Bitcoin Addresses, P2SH Format Explanation and More

Day 4: I will repost this guide daily until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and transaction fees are low. ARE YOU PART OF THE SOLUTION? News: Unconfirmed TX's @ 174K, more exchanges adding SegWit, Core prioritizes SegWit GUI

NOTE Just a daily repost because original OP Bastiat seems to be offline (due to holidays I guess). However, this is quite important as I see much misinformation on which exchanges use segwit or not. Please upvote for awareness.
BACKGROUND
Subhan Nadeem has pointed out that:
If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
A few thousand bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make it happen. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. 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.
  2. 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 exchange now and initiate the verification process so you'll be ready to bail
  3. 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
IMPORTANT NOTE: The mempool is currently overflowing. 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
SELECTED TOP EXCHANGES BY SEGWIT & BATCHING STATUS
There are 2 different Segwit address formats.
  • p2sh - starting with a "3..."
  • bech32 - starting "bc1..."
Not many wallets/exchanges support bech32 yet and will claim the address is invalid if you try to send to it. bech32 ("native Segwit") is a mildly better solution compared to p2sh.
Exchange Batching Status Segwit (p2sh) Send to bech32

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.
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 Transaction if the sending address is a SegWit address.

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?

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?

BACKGROUND
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, and the majority of users have not made the switch themselves.
On Dec 18 2017 Subhan Nadeem has pointed out that: If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
Mass SegWit use alone could empty the mempool, result in blocks that are not completely full, and make it possible to include transactions with $0 fee once again.
On Jan 11 2018 when BTC sends went offline at Coinbase the mempool began to rapidly empty. Later in the day when service was restored there was a sharp spike up in the mempool. Subsequently, that afternoon Brian Armstrong finally had to break his silence on the topic and admitted Coinbase is working on SegWit but has still not deployed it. It appears that this is an important data point that indicates if just a few major exchanges would deploy SegWit the high fees bitcoin is experiencing would be eliminated.
SegWit is just one technique available to exchanges and users to reduce pressure on the Bitcoin network. You can make the switch to SegWit on your next transaction, and pressure exchanges to deploy SegWit NOW along with other actions that will reduce their transaction impact on the network. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. 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.
  2. 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
  3. 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.
  4. 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

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.

P2SH/bech32 FAQs
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.

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
BACKGROUND
On Dec 18 Subhan Nadeem has pointed out that:
If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
A few thousand bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make 80%+ SegWit happen fast. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. 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.
  2. 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
  3. 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.
  4. 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.

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?
P2SH/bech32 FAQs
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 existing 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 backwards 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.

Groestlcoin Release September 2018

Introduction

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.

What's been Happening?

GRSPay Released

We are so excited for this, that it has it's own separate reddit thread. Head over there now at https://www.reddit.com/groestlcoin/comments/9ikr5m/groestlcoin_releases_grspay/? to see more on this!
https://www.melis.io/assets/logo-navbar-4b6f0d372f15b2446d3fa4c68f346e4fb08ee113941186cee58fd6135f3f8b7d.svg

Melis Wallet

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.

In short, we're a bunch of people that claim to be Crypto Evangelists. We strongly believe in cryptocurrencies, and our main promise is to push them up so more people get involved and take all the advantages they offer.

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.

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.

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.

Groestlcoin Sentinel (Android & Blackberry) – Mainnet + Testnet

What is Sentinel?

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.

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?

The original post's content was as follows:
BACKGROUND
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, and the majority of users have not made the switch themselves.
On Dec 18 2017 Subhan Nadeem has pointed out that: If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
Mass SegWit use alone could empty the mempool, result in blocks that are not completely full, and make it possible to include transactions with $0 fee once again.
On Jan 11 2018 when BTC sends went offline at Coinbase the mempool began to rapidly empty. Later in the day when service was restored there was a sharp spike up in the mempool. Subsequently, that afternoon Brian Armstrong finally had to break his silence on the topic and admitted Coinbase is working on SegWit but has still not deployed it. It appears that this is an important data point that indicates if just a few major exchanges would deploy SegWit the high fees bitcoin is experiencing would be eliminated.
SegWit is just one technique available to exchanges and users to reduce pressure on the Bitcoin network. You can make the switch to SegWit on your next transaction, and pressure exchanges to deploy SegWit NOW along with other actions that will reduce their transaction impact on the network. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. 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.
  2. 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
  3. 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.
  4. 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

Since Bastiat hasn't posted this for the past 2 days, I would like to post it because it's necessary.
TL/DR
Bitcoin users can help lower transaction fees and improve Bitcoin by switching to SegWit addresses and encourage wallets and 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.

Where can I get a fee estimate for a SegWit transaction?
How can I get a SegWit address from my Bitcoin Core wallet?
  • Currently, Bitcoin Core hasn't implemented a way to get a SegWit address using the GUI. But you can get a receiving SegWit address using the debug console. To do it, go to the "Receive" tab and copy a receiving address (it starts with 1). Then just click Help > Debug window > Console and type: addwitnessaddress addr
  • You should replace addr with the receiving address that you just copied. Tap enter and you'll get an address (starts with 3). This is your SegWit address. You can use this one to receive funds. When you spend from this address, it will be a SegWit transaction. Easy huh?
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.

SegWit (P2SH) and Native SegWit (bech32) are not the first address formats to exist for Bitcoin accounts. The very first one was Legacy, where addresses would start with a “1”.
