Day 9: I will post this guide regularly until available solutions like SegWit, order batching, and Lightning payment channels are mass adopted, the mempool is empty once again, and tx fees are low. Have you done your part?
If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. If your wallet is not committed to implementing SegWit fast, speak out online any way you can and turn up the pressure. In the meantime start using a wallet that has already implemented SegWit.
If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin.
Spread the word! Contact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch. Use social media to point out the benefits of SegWit adoption.
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange. BEYOND SEGWIT - BATCHING, PAYMENT CHANNELS, LIGHTNING Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it. Users should demand this or walk. Beyond SegWit & Batching, Lightning Network integration will have even more effect. Lightning is now active and exchanges could setup payment channels between each other so that on-chain transactions need not take place. Some ideas have to outline how that might work are here: Google Doc - Lightning Exchanges. Which two bitcoin exchanges will be the first to establish a lightning channel between themselves and offer free/instant transfers between them for their customers? This will happen in 2018 MEMPOOL/SEGWIT STATISTICS

FAQs
If I'm a HODLer, will it help to send my BTC to a SegWit address now?
No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unnecessary transactions for now.
Why is SegWit adoption going so slowly? Is it a time-consuming process, is there risk involved, is it laziness, or something else?
SegWit will require some extra work to be done right and securely. Also, most exchanges let the user pay the fee, and up to now users have not been overly concerned about fees so for some exchanges it hasn't been a priority.
Once Segwit is FULLY adopted, what do we see the fees/transaction times going to?
Times stay the same - fees will go down. How much and for how long depends on what the demand for transactions will be at that time.
What determines bitcoin transaction fees, to begin with?
Fees are charged per byte of data and are bid up by users. Miners will typically include the transaction with the highest fee/byte first.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download the latest version of Electrum to generate a SegWit address. A transaction between two SegWit addresses is a SegWit transaction. A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction. A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address. Source: HowToToken
What wallet are you using to "batch your sends"? And how can I do that?
Using Electrum, the "Tools" menu option: "Pay to many". Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?
What are the two SegWit address formats and why do they exist?
It's been a challenge for wallet developers to implement SegWit in a way that users can easily and without too much disruption migrate from legacy to SegWit addresses. The first wallets to enable SegWit addresses – Ledger, Trezor, Core, GreenAddress – use so-called “nested P2SH addresses.” This means they take the existing Pay 2 Script Hash address – starting with a “3” – and put a SegWit address into it. This enables a high grade of compatibility to exist wallets as every wallet is familiar with these addresses, but it is a workaround which results in SegWit transactions needing around 10 percent more space than they otherwise would. Electrum 3.0 was the first wallet to use bech32 addresses instead of nested p2sh addresses. Source: BTCManager.com
What is the difference in address format between SegWit address formats P2SH and bech32?
P2SH starts with "3..." bech32 starts with "bc1..."
Which addresses can I send from/to?
P2SH Segwit addresses can be sent to using older Bitcoin software with no Segwit support. This supports backward compatibility bech32 can only be sent to from newer Bitcoin software that support bech32. Ex: Electrum Source: BitcoinTalk.org
Why did ThePirateBay put up two Bitcoin donation addresses on their frontpage, one bech32 and one not?
The address starting with a "3..." is a P2SH SegWit address that can be sent BTC from any bitcoin address including a legacy address. The address starting with a "bc1..." is a bech32 SegWit address that can only be sent to from newer wallets that support bech32.

Day 7: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and tx fees are low. Do you want low tx fees, because this is how you get low tx fees
TL/DR Bitcoin users can help lower transaction fees and improve bitcoin by switching to SegWit addresses and encourage wallets/exchanges to do the same. SUMMARY Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work on integrating it. Others, such as Zebpay in India have already implemented SegWit and are reaping the benefits of reduced transaction fees. If bitcoin users demand SegWit now it will temporarily relieve the transaction backlog while more even more advanced solutions such as Lightning are developed. Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it. There is an opportunity now for all bitcoin users to individually contribute to help strengthen and improve the bitcoin protocol. At this point, the process requires a bit of work/learning on the part of the user, but in doing so you'll actually be advancing bitcoin and leaving what could turn out to be a multi-generational legacy for humanity.

dcrd: Version 1.3.0 RC1 (Release Candidate 1) is out! The main features of this release are significant performance improvements, including some that benefit SPV clients. Full release notes and downloads are on GitHub. The default minimum transaction fee rate was reduced from 0.001 to 0.0001 DCkB. Do not try to send such small fee transactions just yet, until the majority of the network upgrades. Release process was changed to use release branches and bump version on the master branch at the beginning of a release cycle. Discussed in this chat. The codebase is ready for the new Go 1.11 version. Migration to vgo module system is complete and the 1.4.0 release will be built using modules. The list of versioned modules and a hierarchy diagram are available here. The testnet was reset and bumped to version 3. Comments are welcome for the proposal to implement smart fee estimation, which is important for Lightning Network. @matheusd recorded a code review video for new Decred developers that explains how tickets are selected for voting. dcrwallet: Version 1.3.0 RC1 features new SPV sync mode, new ticket buyer, new APIs for Decrediton and a host of bug fixes. On the dev side, dcrwallet also migrated to the new module system. Decrediton: Version 1.3.0 RC1 adds the new SPV sync mode that syncs roughly 5x faster. The feature is off by default while it receives more testing from experienced users. Other notable changes include a design polish and experimental Politeia integration. Politeia: Proposal editing is being developed and has a short demo. This will allow proposal owners to edit their proposal in response to community feedback before voting begins. The challenges associated with this feature relate to updating censorship tokens and maintaining a clear history of which version comments were made on. @fernandoabolafio produced this architecture diagram which may be of interest to developers. @degeri joined to perform security testing of Politeia and found several issues. dcrdata: mainnet explorer upgraded to v2.1 with several new features. For users: credit/debit tx filter on address page, showing miner fees on coinbase transaction page, estimate yearly ticket rewards on main page, cool new hamburger menu and keyboard navigation. For developers: new chain parameters page, experimental Insight API support, endpoints for coin supply and block rewards, testnet3 support. Lots of minor API changes and frontend tweaks, many bug fixes and robustness improvements. The upcoming v3.0 entered beta and is deployed on beta.dcrdata.org. Check out the new charts page. Feedback and bug reports are appreciated. Finally, the development version v3.1.0-pre is on alpha.dcrdata.org. Android: updated to be compatible with the latest SPV code and is syncing, several performance issues are worked on. Details were posted in chat. Alpha testing has started, to participate please join #dev and ask for the APK. iOS: backend is mostly complete, as well as the front end. Support for devices with smaller screens was improved. What works now: creating and recovering wallets, listing of transactions, receiving DCR, displaying and scanning QR codes, browsing account information, SPV connection to peers, downloading headers. Some bugs need fixing before making testable builds. Ticket splitting: v0.6.0 beta released with improved fee calculation and multiple bug fixes. docs: introduced new Governance section that grouped some old articles as well as the new Politeia page. @Richard-Red created a concept repository sandbox with policy documents, to illustrate the kind of policies that could be approved and amended by Politeia proposals. decred.org: 8 contributors added and 4 removed, including 2 advisors (discussion here). decredmarketcap.com is a brand new website that shows the most accurate DCR market data. Clean design, mobile friendly, no javascript required. Dev activity stats for August: 239 active PRs, 219 commits, 25k added and 11k deleted lines spread across 8 repositories. Contributions came from 2-10 developers per repository. (chart)
Network
Hashrate: went from 54 to 76 PH/s, the low was 50 and the new all-time high is 100 PH/s. BeePool share rose to ~50% while F2Pool shrank to 30%, followed by coinmine.pl at 5% and Luxor at 3%. Staking: 30-day average ticket price is 95.6 DCR (+3.0) as of Sep 3. During the month, ticket price fluctuated between a low of 92.2 and high of 100.5 DCR. Locked DCR represented between 3.8 and 3.9 million or 46.3-46.9% of the supply. Nodes: there are 217 public listening and 281 normal nodes per dcred.eu. Version distribution: 2% at v1.4.0(pre) (dev builds), 5% on v1.3.0 (RC1), 62% on v1.2.0 (-5%), 22% on v1.1.2 (-2%), 6% on v1.1.0 (-1%). Almost 69% of nodes are v.1.2.0 and higher and support client filters. Data snapshot of Aug 31.
ASICs
Obelisk posted 3 email updates in August. DCR1 units are reportedly shipping with 1 TH/s hashrate and will be upgraded with firmware to 1.5 TH/s. Batch 1 customers will receive compensation for missed shipment dates, but only after Batch 5 ships. Batch 2-5 customers will be receiving the updated slim design. Innosilicon announced the new D9+ DecredMaster: 2.8 TH/s at 1,230 W priced $1,499. Specified shipping date was Aug 10-15. FFMiner DS19 claims 3.1 TH/s for Blake256R14 at 680 W and simultaneously 1.55 TH/s for Blake2B at 410 W, the price is $1,299. Shipping Aug 20-25. Another newly noticed miner offer is this unit that does 46 TH/s at 2,150 W at the price of $4,720. It is shipping Nov 2018 and the stats look very close to Pangolin Whatsminer DCR (which has now a page on asicminervalue).
Integrations
www.d1pool.com joined the list of stakepools for a total of 16. Australian CoinTreeadded DCR trading. The platform supports fiat, there are some limitations during the upgrade to a new system but also no fees in the "Early access mode". On a related note, CoinTree is working on a feature to pay household bills with cryptocurrencies it supports. Three new OTC desks were added to exchanges page at decred.org. Two mobile wallets integrated Decred:
Coinomiadded Decred to their Android and iOS wallets. In addition to the Apple App Store and Google Play you can download the APK directly. Coinomi features an integrated cryptocurrency exchange and is the first company to offer a mobile Decred wallet.
Reminder: do your best to understand the security and privacy model before using any wallet software. Points to consider: who controls the seed, does the wallet talk to the nodes directly or via middlemen, is it open source or not?
Adoption
Merchants:
Bit Dialsannounced DCR support via GloBee at their bitdials.eu luxury boutique. Their separate supercar and classic car shop bitcars.eu also accepts DCR, either via GloBee or with manual invoicing in case of privacy concerns.
Sheldon Storere-enabled DCR payments. The shop sells gift cards for Amazon, iTunes, Netflix and many more.
Marketing
Targeted advertising report for August was posted by @timhebel. Facebook appeal is pending, some Google and Twitter campaigns were paused and some updated. Read more here. Contribution to the @decredproject Twitter account has evolved over the past few months. A #twitter_ops channel is being used on Matrix to collaboratively draft and execute project account tweets (including retweets). Anyone with an interest in contributing to the Twitter account can ask for an invitation to the channel and can start contributing content and ideas there for evaluation by the Twitter group. As a result, no minority or unilateral veto over tweets is possible. (from GitHub)

For those willing to help with the events:
BAB: Hey all, we are gearing up for conference season. I have a list of places we hope to attend but need to know who besides @joshuam and @Haon are willing to do public speaking, willing to work booths, or help out at them? You will need to be well versed on not just what is Decred, but the history of Decred etc... DM me if you are interested. (#event_planning) The Decred project is looking for ambassadors. If you are looking for a fun cryptocurrency to get involved in send me a DM or come talk to me on Decred slack. (@marco_peereboom, longer version here)
Media
Decred Assembly episode 21 is available. @jy-p and lead dcrwallet developer @jrick discussed SPV from Satoshi's whitepaper, how it can be improved upon and what's coming in Decred. Decred Assembly episodes 1-21 are available in audio only format here. New instructional articles on stakey.club: Decrediton setup, Deleting the wallet, Installing Go, Installing dcrd, dcrd as a Linux service. Available in both English and Portuguese. Decred scored #32 in the August issue of Chinese CCID ratings. The evaluation model was explained in this interview. Satis Group rated Decred highly in their cryptoasset valuation research report (PDF). This was featured by several large media outlets, but some did not link to or omitted Decred entirely, citing low market cap. Featured articles:
Decred Investor Interviews: Ciarán O’Leary, General Partner, BlueYard Capital (medium)
Decred Update Research Report by Node Blockchain (medium), and the corresponding full 11-page report (Google Drive)
Is Decred worth my time and money? by Fabien Pelissier (medium), and the full 13-page Decred Analysis (PDF)
One private work channel was successfully migrated to Matrix.
Stylish room avatars were set.
@Haon has prepared a short guide to help new Matrix users get started and join the Decred rooms.
Highlights:
A thread was started to discuss changes to Decred jargon with the intent to make it more consistent and accessible to newcomers. The question whether changing "official" terminology requires stakeholder approval was touched in this thread and in #documentation.
Project fund transparency and constitution were extensively discussed on Reddit and in #general.
Pre-proposal to use Politeia to approve Politeia as a legitimate decision-making tool for Decred.
Reddit: substantive discussion about Decred cons; ecosystem fund; a thread about voter engagement, Politeia UX and trolling; idea of a social media system for Decred by @michae2xl; how profitable is the Obelisk DCR1. Chats: cross-chain trading via LN; plans for contractor management system, lower-level decision making and contractor privacy vs transparency for stakeholders; measuring dev activity; what if the network stalls, multiple implementations of Decred for more resilience, long term vision behind those extensive tests and accurate comments in the codebase; ideas for process for policy documents, hosting them in Pi and approving with ticket voting; about SPV wallet disk size, how compact filters work; odds of a wallet fetching a wrong block in SPV; new module system in Go; security of allowing Android app backups; why PoW algo change proposal must be specified in great detail; thoughts about NIPoPoWs and SPV; prerequisites for shipping SPV by default (continued); Decred vs Dash treasury and marketing expenses, spending other people's money; why Decred should not invade a country, DAO and nation states, entangling with nation state is poor resource allocation; how winning tickets are determined and attack vectors; Politeia proposal moderation, contractor clearance, the scale of proposals and decision delegation, initial Politeia vote to approve Politeia itself; chat systems, Matrix/Slack/Discord/RocketChat/Keybase (continued); overview of Korean exchanges; no breaking changes in vgo; why project fund burn rate must keep low; asymptotic behavior of Decred and other ccs, tail emission; count of full nodes and incentives to run them; Politeia proposal translations and multilingual environment. An unusual event was the chat about double negatives and other oddities in languages in #trading.
Markets
DCR started the month at USD 56 / BTC 0.0073 and had a two week decline. On Aug 14 the whole market took a huge drop and briefly went below USD 200 billion. Bitcoin went below USD 6,000 and top 100 cryptos lost 5-30%. The lowest point coincided with Bitcoin dominance peak at 54.5%. On that day Decred dived -17% and reached the bottom of USD 32 / BTC 0.00537. Since then it went sideways in the USD 35-45 / BTC 0.0054-0.0064 range. Around Aug 24, Huobi showed DCR trading volume above USD 5M and this coincided with a minor recovery. @ImacallyouJawdy posted some creative analysis based on ticket data.
Relevant External
StopAndDecrypt published an extensive article "ASIC Resistance is Nothing but a Blockchain Buzzword" that is much in line with Decred's stance on ASICs. The ongoing debates about the possible Sia fork yet again demonstrate the importance of a robust dispute resolution mechanism. Also, we are lucky to have the treasury. Mark B Lundeberg, who found a vulnerability in atomicswap earlier, published a concept of more private peer-to-peer atomic swaps. (missed in July issue) Medium took a cautious stance on cryptocurrencies and triggered at least one project to migrate to Ghost (that same project previously migrated away from Slack). Regulation: Vietnam bans mining equipment imports, China halts crypto events and tightens control of crypto chat groups. Reddit was hacked by intercepting 2FA codes sent via SMS. The announcement explains the impact. Yet another data breach suggests to think twice before sharing any data with any company and shift to more secure authentication systems. Intel and x86 dumpsterfire keeps burning brighter. Seek more secure hardware and operating systems for your coins. Finally, unrelated to Decred but good for a laugh: yetanotherico.com.

As always, the past 3 months since 22nd June have been crazy busy. The bears might still be around, but the show must go on and of course has not slowed the Groestlcoin development team in the slightest. Here’s a quick overview of what has already happened since the last release: - Integrated into the bitbns exchange, with the ability to buy Groestlcoin directly with the Indian Rupee. - Groestlcoin Rebrand Vote – Whilst there was much talk and push for a rebrand vote, the overall result was almost unanimously in favour of keeping our unique and conversation-starting name. With just 83 votes to Rebrand, and 2577 votes to No Rebrand. Thank you for all who voted, the funds raised are being used to fund ongoing hosting and development costs. - Integrated into the Cryptobridge exchange. Cryptobridge is a popular decentralised exchange where you always hold the private keys to your funds, only YOU have access to them. - Groestlcoin has been added to SimpleSwap – Groestlcoin can now be swapped with over 100 other cryptocurrencies, without signing up! - Groestlcoin has been added to UnoDax, one of the leading cryptocurrency exchanges in India, with TUSD, BTC and INR trading pairs. - Groestlcoin has been added to SwapLab.cc, where you can buy Groestlcoin using Bitcoin and over 50 other altcoins. Purchasing with VISA/Mastercard is coming VERY SOON. Discussed later: - Groestlcoin has been listed on #3 largest exchange in the world on volume, Huobi Global! More on this to come further on in the announcements. - Groestlcoin has been added to the Guarda Multi-Currency Wallet. - Groestlcoin has been added to Melis Multi-Device, Multi-Account, Multi-Platform, Multi-Signature advanced wallet! Already this list is far more than most other cryptocurrencies have achieved in the past 3 months. But this is just the tip of the iceberg of what has been developed.
The the most advanced wallet for Bitcoin, Bitcoin Cash, Litecoin and now Groestlcoin.
With Melis you have the complete control of your bitcoins and private keys, you can define spending limits policies and make use of two or more factors authentication. Melis is open source, published on GitHub.
How Melis Works?
You can create as many accounts as you want. An account is a part of your wallet that can be customised to your requirements. You can choose how many co-signers are required to spend funds. The accounts are completely independent and act like separate wallets from each other but can be accessed via the same details. A core feature of Melis is the ability to set a ‘primary’ device. With this you can set an account as ‘Secure’ so it is only viewable (and accessible at all) from the Primary device. You can have a savings account hidden from the outside world whilst also having your ‘spending’ funds available on the go. With Melis you can create a multi-signature account between N people, where up to N signatures are required to sign a transaction, choosing if any of those should be mandatory.
Core Features:
Multi-Device – Ability to hide accounts from all but the primary account.
Multi-Account – Multiple, entirely separate accounts in one wallet.
Multi-Platform – Available on iOS, Android, Web, Windows, Linux and Mac OS
Multi-Signature – Create multi-signature accounts between many people, where a certain amount of people’s signatures is required to sign a transaction. Some can be required before a transaction is signed.
Native support for many currencies – Multiple currencies are supported, accessed all from the same wallet and backup keywords.
Advanced Coin Control (Choose which UTXO are involved in the transaction), multiple destinations and manual fee settings.
2FA support for enhanced security, also available via Telegram.
Wrong-Currency detection. The server knows if someone sends BTC to a BCH address and visa versa and automatically creates a new account to be able to recover the funds.
A single backup using standard BIP39 mnemonics is valid and enough for an unlimited number of transactions, address and different account types
Safer than ever! Desktop Light Wallet - Anonymous and fast!
With Guarda Multi-currency Desktop Light Wallet you don’t need to register. Guarda has no access to your private keys or funds. You can receive, send, store, buy and exchange cryptocurrencies in complete anonymity and safety. All these features are available on Linux, Windows or MacOS. Choose the one that suits you!

More information from Blockchain Financial
Back in 2014, the world was taken by storm when Facebook approved the first cryptocurrencies tipping apps. The first was for Dogecoin, and the second was for multiple coins. The project was hosted on whitepuma.net, and persisted for almost two years, built up a massive user community and gave a home to Bitcoin, Litecoin, Dogecoin and dozens of other bitcoin-based altcoins. After very active months, the tipping hype started to fade away. Then, the developers decided to jump into the next stage: bringing not only tipping, but also mining and a widget that could be embedded on websites to allow everyone to accept payments. Sadly, the work was never completed because the project started to require an unsustainable amount of resources. Then, in a painful decision, a shutdown was announced by December 2015. A couple of months after whitepuma.net was closed, the source code was released by its creator as Open Source on GitHub. But it wasn't maintained. Now, some of the original members of the dev and admin teams gathered up with a handful of the WhitePuma's elite users, and decided to make something good with the best pieces of the old source code. That, with fresh new ideas and the power of the BardCanvas engine, synthesized the core of Blockchain Financial.
Huobi was founded in China and is now based in Singapore, with offices in Hong Kong, South Korea, Japan and the North America, currently sitting #3 in volume on Coinmarketcap. Huobi is a great leap forward for our growing presence in Asia and we are very excited to be listed here! You can find the official Huobi announcement here.
Groestlcoin Core v2.16.3 - Please Update ASAP
A new major Groestlcoin Core version 2.16.3 is now available for download which includes both a Denial of Service component and a critical inflation vulnerability, so it is recommended to upgrade to it if you are running a full Groestlcoin node or a local Groestlcoin Core wallet. v2.16.3 is now the official release version of Groestlcoin Core. This is a new major version release with a very important security updates. It is recommended to upgrade to this version as soon as possible. Please stop running versions of Groestlcoin Core affected by CVE-2018-17144 ASAP: These are 2.13.3 and 2.16.0. As a result in this, all exchanges and services have been asked to upgrade to this version, so please be patient if wallets go in to maintenance mode on these services.
What's new in version v2.16.3?
This is a major release of Groestlcoin Core fixing a Denial of Service component and a critical inflation vulnerability (https://nvd.nist.gov/vuln/detail/CVE-2018-17144) exploitable by miners that has been discovered in Groestlcoin Core version 2.13.3 and 2.16.0. It is recommended to upgrade to 2.16.3 as soon as possible. If you only occasionally run Groestlcoin Core, then it's not necessary to run out and upgrade it right this second. However, you should upgrade it before you next run it. If you know anyone who is running an older version, tell them to upgrade it ASAP. Stored funds are not at risk, and never were at risk. At this time we believe over half of the Groestlcoin hashrate has upgraded to patched nodes. We are unaware of any attempts to exploit this vulnerability. However, it still remains critical that affected users upgrade and apply the latest patches to ensure no possibility of large reorganizations, mining of invalid blocks, or acceptance of invalid transactions occurs.
The Technicals
In Groestlcoin Core 2.13.3, an optimization was added (Bitcoin Core PR #9049) which avoided a costly check during initial pre-relay block validation that multiple inputs within a single transaction did not spend the same input twice which was added in 2012 (Bitcoin Core PR #443). While the UTXO-updating logic has sufficient knowledge to check that such a condition is not violated in 2.13.3 it only did so in a sanity check assertion and not with full error handling (it did, however, fully handle this case twice in prior to 2.1.0.6). Thus, in Groestlcoin Core 2.13.3, any attempts to double-spend a transaction output within a single transaction inside of a block will result in an assertion failure and a crash, as was originally reported. In Groestlcoin Core 2.16.0, as a part of a larger redesign to simplify unspent transaction output tracking and correct a resource exhaustion attack the assertion was changed subtly. Instead of asserting that the output being marked spent was previously unspent, it only asserts that it exists. Thus, in Groestlcoin Core 2.16.0, any attempts to double-spend a transaction output within a single transaction inside of a block where the output being spent was created in the same block, the same assertion failure will occur. However, if the output being double-spent was created in a previous block, an entry will still remain in the CCoin map with the DIRTY flag set and having been marked as spent, resulting in no such assertion. This could allow a miner to inflate the supply of Groestlcoin as they would be then able to claim the value being spent twice. Groestlcoin would like to publicly thank Reddit user u/Awemany for finding CVE-2018-17144 and reporting it (https://lists.linuxfoundation.org/pipermail/bitcoin-core-dev/2018-Septembe000064.html). You deserve gratitude and appreciation from cryptoworld, and you have ours.

Electrum-GRS is a lightweight "thin client" groestlcoin wallet Windows, MacOS and Linux based on a client-server protocol. Its main advantages over the original Groestlcoin client include support for multi-signature wallets and not requiring the download of the entire block chain.
Changes:
Qt GUI: seed word auto-complete during restore
performance improvements (wallet, and Qt GUI)
hardware wallets: show debug message during device scan
add regtest support (via --regtest flag)
other minor bugfixes and usability improvements
If present, libsecp256k1 is used to speed up elliptic curve operations. The library is bundled in the Windows, MacOS, and Android binaries. On Linux, it needs to be installed separately.
Transactions that are dropped from the mempool are kept in the wallet as 'local', and can be rebroadcast. Previously these transactions were deleted from the wallet.
The scriptSig and witness part of transaction inputs are no longer parsed, unless actually needed. The wallet will no longer display 'from' addresses corresponding to transaction inputs, except for its own inputs.
The partial transaction format has been incompatibly changed. This was needed as for partial transactions the scriptSig/witness has to be parsed, but for signed transactions we did not want to do the parsing. Users should make sure that all instances of Electrum-GRS they use to co-sign or offline sign, are updated together.
Signing of partial transactions created with online imported addresses wallets now supports significantly more setups. Previously only online p2pkh address + offline WIF was supported. Now the following setups are all supported: > online {p2pkh, p2wpkh-p2sh, p2wpkh} address + offline WIF, > online {p2pkh, p2wpkh-p2sh, p2wpkh} address + offline seed/xprv, > online {p2sh, p2wsh-p2sh, p2wsh}-multisig address + offline seeds/xprvs > (Potentially distributed among several different machines) Note that for the online address + offline HD secret case, you need the offline wallet to recognize the address (i.e. within gap limit). Having an xpub on the online machine is still the recommended setup, as this allows the online machine to generate new addresses on demand.
Segwit multisig for bip39 and hardware wallets is now enabled (both p2wsh-p2sh and native p2wsh).
Ledger: offline signing for segwit inputs (#3302) This has already worked for Trezor. Offline segwit signing can be combined with online imported addresses wallets.
Added Revealer plugin. ( https://revealer.cc ) Revealer is a seed phrase back-up solution. It allows you to create a cold, analog, multi-factor backup of your wallet seeds, or of any arbitrary secret. The Revealer utilizes a transparent plastic visual one time pad.
Fractional fee rates: the Qt GUI now displays fee rates with 0.1 gro/byte precision, and also allows this same resolution in the Send tab.
Hardware wallets: a "show address" button is now displayed in the Receive tab of the Qt GUI. (#4316)
Electrum-grs is a lightweight "thin client" groestlcoin wallet Android based on a client-server protocol. Its main advantages over the original Groestlcoin client include support for multi-signature wallets and not requiring the download of the entire block chain.
Changes
Android: fix some crashes
If present, libsecp256k1 is used to speed up elliptic curve operations. The library is bundled in the Windows, MacOS, and Android binaries. On Linux, it needs to be installed separately.
Two-factor authentication is available on Android. Note that this will only provide additional security if one time passwords are generated on a separate device.
Semi-automated crash reporting is implemented for Android.
Qt/Kivy: added "gro" as optional base unit.
Kivy GUI: significant performance improvements when displaying history and address list of large wallets; and transaction dialog of large transactions.
Groestlcoin EasyVanity Released
Groestlcoin EasyVanity is a Windows app is built from the ground-up in C# and makes it easier than ever before to create your very own bespoke Groestlcoin address(es), even whilst not connected to the internet! You can even generate multiple keys with the same prefix and leave it on overnight whilst your CPU or GPU collects and stores these addresses locally.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then Groestlcoin EasyVanity is the right choice for you to create a more personalized address.
Features
• Ability to continue finding keys after first one is found • Includes warning on startup if connected to the internet • Ability to output keys to a text file (And shows button to open that directory) • Ability to make your match case sensitive (Where possible) • Show and hide the private key with a simple toggle switch, and copy the private key straight to your clipboard • Show full output of commands • Includes statistics whilst the application is running • Ability to choose between Processor (CPU) and Graphics Card (GPU) • Automatically detects 32 or 64 bit systems • Features both a Light and Dark Material Design inspired Themes • EasyVanity's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky. • EasyVanity includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. • Prefixes are exact strings that must appear at the beginning of the address. When searching for prefixes, Easyvanity will ensure that the prefix is possible, and will provide a difficulty estimate. • The percentage displayed just shows how probable it is that a match would be found in the session so far. If it finds your address with 5% on the display, you are extremely lucky. If it finds your address with 92% on the display, you are unlucky. If you stop EasyVanity with 90% on the display, restart it, and it finds your address with 2% on the display, your first session was unlucky, but your second session was lucky. • EasyVanity uses the OpenSSL random number generator. This is the same RNG used by groestlcoin and a good number of HTTPS servers. It is regarded as well-scrutinized. Guessing the private key of an address found by EasyVanity will be no easier than guessing a private key created by groestlcoin itself. • To speed up address generation, EasyVanity uses the RNG to choose a private key, and literally increments the private key in a loop searching for a match. As long as the starting point is not disclosed, if a match is found, the private key will not be any easier to guess than if every private key tested were taken from the RNG. EasyVanity will also reload the private key from the RNG after 10,000,000 unsuccessful searches (100M for oclvanitygen), or when a match is found and multiple patterns are being searched for. • Free software - MIT. Anyone can audit the code. • Written in C# - The code is short, and easy to review.

[uncensored-r/Bitcoin] Day 7: I will post this guide regularly until available solutions like SegWit & order batching ar...
The following post by Bastiat is being replicated because some comments within the post(but not the post itself) have been silently removed. The original post can be found(in censored form) at this link: np.reddit.com/ Bitcoin/comments/7ojt5f The original post's content was as follows:
TL/DR Bitcoin users can help lower transaction fees and improve bitcoin by switching to SegWit addresses and encourage wallets/exchanges to do the same. SUMMARY Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work on integrating it. Others, such as Zebpay in India have already implemented SegWit and are reaping the benefits of reduced transaction fees. If bitcoin users demand SegWit now it will temporarily relieve the transaction backlog while more even more advanced solutions such as Lightning are developed. Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it. There is an opportunity now for all bitcoin users to individually contribute to help strengthen and improve the bitcoin protocol. At this point, the process requires a bit of work/learning on the part of the user, but in doing so you'll actually be advancing bitcoin and leaving what could turn out to be a multi-generational legacy for humanity. MEMPOOL/SEGWIT STATISTICS
If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. In the meantime start using a wallet that has already implemented SegWit.
If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin.
Spread the word! Conact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange.

Paper
FAQs If I'm a HODLer, will it help to send my BTC to a SegWit address now?
No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unneccessary transactions for now.
Why is SegWit adoption going so slowly? Is it a time-consuming process, is there risk involved, is it laziness, or something else?
SegWit will require some extra work to be done right and securely. Also, most exchanges let the user pay the fee, and up to now users have not been overly concerned about fees so for some exchanges it hasn't been a priority.
Once Segwit is FULLY adopted, what do we see the fees/transaction times going to?
Times stay the same - fees will go down. How much and for how long depends on what the demand for transactions will be at that time.
What determines bitcoin transaction fees, to begin with?
Fees are charged per byte of data and are bid up by users. Miners will typically include the transaction with the highest fee/byte first.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download Electrum v3.0.3 to generate a SegWit address. A transaction between two SegWit addresses is a SegWit transaction. A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction. A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address. Source: HowToToken
What wallet are you using to "batch your sends"? And how can I do that?
Using Electrum, the "Tools" menu option: "Pay to many". Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?

ABOUT FINATCH Finatch is a private Blockchain Technology Company which aim's at revolutrionizing the Blockchain Technology industry. Looking at the lack of stable, fast and reliable decentralized crypto exchanges which causes inconviniences to crypto traders in the space. We have come up with the solution to the problems faced by decentralized exchanges. There are basically two different types of exchanges: Centralized and Decentralized exchanges. We will focus on the Deentralized exchange system. We have a strong belief that Decentralized based crypto exchanges will be bigger than Centralized based crypto exchanges in the nearest future, because Blockchain is all about Decentralization. They will play an evermore role in the world of finance, and we call this FINATCH EXCHANGE. FINATCH EXCHANGE Finatch Exchange is a Decntralized crypto exchange, which is run and powered by the Finatch Smart Contract Blockchain. Problems Poor technical architecture in Decentralized exchanges There are a good number of exchanges set up by professionals who have little or no experience in finance or in operating an exchange. They often take the easiest route to get the system up and running. While this may work well in the beginning, as traffic grows, the system will not be able to handle the increased load. Exchange systems need to be engineered from the ground up with security, efficiency, speed, and scalability in mind. This often slows down the initial development, but is critical for long-term success. Our team has decades of combined experience building and maintaining world class financial systems that shape the economy. We understand how these systems are built from the ground up. Slow Smart Contract confirmation time Deployment of Smart contract on the blockchain takes time and causes inconveniences becauses of the poorly built blockchain, this results in a bad user experience in decentralized crypto exchanges. Our team has designed a new and capable type of Blockchain that speeds up confirmation time for smart contratcts, making the platform user friendly and smooth. Insecured Platform There are hundreds of exchanges that went down due to being hacked. Finatch is built to top notch quality, audited, and penetration tested. We have experience building financial systems to the highest security standards and strive to ensure security first. Poor market liquidity Professional traders and normal users are significantly affected by this. Having a shallow orderbook means high slippage when trading, which is very expensive for traders. Finatch’s team have been in both the finance and crypto industry for many years. The team has worked on and operated a number of exchanges, and have accumulated a large network of partners in this space. These partners will be key in bootstrapping the exchange. Poor customer service Traders are a different breed when it comes to users. Understanding the trader mentality is vital for running a successful exchange. Money is literally on-the-line. Many exchange service trades as if they were running a social media site. A 3-second delay in seeing your friends’ status update would hardly be noticed, but on an exchange, the same would be unacceptable, resulting in a torrent of user complaints. In additional to the technology stack, Finatch is built with service in mind. Finatch shares and supports responsibilities across the entire staff and company. When a trader has a problem, they get an answer directly from someone who knows the system and not someone reading from a script. Limited access to decentralized services There are few existing decentralized exchanges with close to good user interface and lacks quick and reasonable smart contract transaction fees, causing slow platorm functioning. Our team has designed a new and capable type of Blockchain that speeds up confirmation time for smart contratcts, making the platform user friendly and smooth. Poor internationalization and language support Blockchains have no borders. Most exchanges focus only on one language or one country. Our international multi-lingual team has extensive working experience in North America, Europe, Asia and Africa and we are able to smoothly support the global market. Lack of transparency All trading activities should be decentralized and open to the general public to insure trust and transparency in trades. Centralized crypto exchanges lack this quality. Finatch runs on a Decentralized crypto platform where all trading activities are transparent. Finatch is a Crypto Decentralized crypto exchange that has the feel and look of Centralized Crypto exchange but with more convinience And extra Blockchain Security Layer. An Exchange where you own your private keys. Finatch exchange is a huge decentralized trading exchange platform equipped with various sub-platform, trading tools and secure decentralized wallet. Finatch exchange consists of various sub platforms to choose from, this changes the trading experience namely: 1. Binary Platform: Fin vault platform, FinBox platform 2. Finatch trading tools: Finatch exchange have the best trading tools ready for traders on all our trading platform, taking trading experience to the next level. You can choose from our multiple trading tools the one that suits your trading skills. 3.Andriod and iOs Mobile Trading Application.

You can be certain, on our exchange, that your orders will never be stuck due to the matching engine being overwhelmed. FEATURE ROLLOUT We will roll out the platform in roughly the following order: Decentralized (on-chain) exchange Spot trading Margin trading Futures Anonymous instant exchange and more...

Create your own tokens, automate supply chain management and engage in self-executing agreements in a standardized environment, verified and tested for stability. SMART CONTRACT LIFE CYCLE MANAGMENT Finatch, in cooperation with its academic partners, develops tools and methods to standardize the workflow for business smart contract development. This includes the formally verifiable translation of human-readable agreements to machine smart contracts, and the error-resilient specification of their elements, terms and conditions. SETTING INDUSTRY STANDARDS Cooperating with a series of partners and third parties, Finatch aims to establish a smart contract hub, offering secure and thoroughly tested contract templates, tailor fitted for a multitude of industries and use cases, such as supply chain management, telecommunications, IoT, social networking, Crypto exchanges and many more. ABOUT FIN COIN FIN Coin is a decentralised Cryptocurrency based on Finatch. It is the local based Cryptocurrency of Finatch Blockchain. FIN Coins are cryptographic software tokens used to engage with distributed applications (DApps) and smart contracts on the Finatch Platform. FIN Coins will serve as the staking currency of the Finatch blockchain and fuel computational operations performed by the Finatch network. SPECIFICATION Total Pre-Mined Supply: 200,000,000 Block Target: 3-15 seconds Stake Return: ~5 FIN Coin Algorithm: Scrypt PoW/PoS and FT The FINATCH Foundation: Governance Structure The development and maintenance of the FINATCH Blockchain, as well as all services provided by FINATCH, are directed and supervised by the FINATCH Foundation - a non-profit organization, representing FINATCH’s stake and token holders as elaborated below. In order to avoid the inefficient conduct, open source and blockchain projects often suffer from, and to ensure a coherent and standardized implementation of the FINATCH blockchain, the FINATCH Foundation was established under the guidance and support of FINATCH Inc. The Foundation will oversee the development of the FINATCH Blockchain, advocate governance transparency, and promote the safety and harmony of the open source ecosystem. The design of the Foundation’s governance structure mainly considers sustainability, management effectiveness, and fund-raising security in the open source community. The Foundation consists of various committees, such as Executive Judgment, Code Review, Finance & HR, as well as Marketing & PR. The different committees work in cooperation to manage FINATCH’s daily operations and special occasions with detailed operational procedures and rules.

Most importantly, this technology allows these blockchain parameters to be changed without any disruption to the ecosystem. After a setting change, no new software must be downloaded by users, and no intervention is needed from stakers, miners and node operators. The way the DGP works is relatively straightforward. First, a governing party for the DGP makes a proposal to change a parameter. Afterward, all the governing parties for the DGP can vote on the proposal, and if it receives enough approval votes, then the parameter change proposal becomes active. The proposal data is then placed in a standardized format and a particular storage space so that the blockchain software can easily access it without needing to execute the DGP contract directly.

The Foundation will also seek complementary services to aid our efforts in transparency and professionalism with a professional auditing firm, legal team and a professional digital asset management solution. We hope this will help promote the healthy development of the FINATCH Project and serve as a model for other projects.
