Ledger Live adds Coin control: Here's why that matters.

Ledger Live adds Coin control: Here's why that matters.
Ledger Live version 2.11.1 (download link) adds Coin control for power users.
The coin control feature gives advanced users more granular control over their wallets. It enables them to change how and which coins are selected when making transactions. This increases their ability to manage their privacy and the network fees they will have to pay to spend their account balance.
More control over your coins

How does it work?

The account balance for Bitcoin and its derivatives consists of all the unspent transaction outputs (UTXOs) in the account. You can think of UTXOs as the coins in a regular wallet. When you receive money, you collect coins in your wallet. Then, when you want to make a payment, you get to choose which coins you pick from your wallet. Do you pick the largest coins first? Or do you want to spend all the smaller value coins to lighten up your wallet? Similar considerations can be made when creating a Bitcoin or Bitcoin derivative (altcoin) transaction.
Before the Coin Control feature was released, all transactions involving Bitcoin (and altcoins) automatically selected their coins using the First-In-First-Out (FIFO) algorithm. This strategy includes the oldest coin in the account, and when the amount is not sufficient the second-oldest coin is added, and so forth.
As of Ledger Live version 2.11.1, users are able to make use of a dedicated Coin Control tool to choose the coin selection strategy and the coins that may be spent.

Using Coin control in Ledger Live

Coin control is available in Advanced options in the Send flow
  1. Click on Send, choose an account to debit, and enter a recipient address. Click on Continue.
  2. Enter an amount and click on Advanced options. You will then see: - The currently selected, default coin selection strategy: Oldest coins first (FIFO). - A toggle to enable Replace-By-Fee (RBF). - A toggle to include coins from unconfirmed, replaceable transactions.
  3. Click on Coin control. The coin control modal opens.
  4. Select a Coin selection strategy from the dropdown menu: - Oldest coins first (FIFO). This is the default strategy that spends the oldest coins first. - Minimize fees (optimize size). This strategy tries to minimize the byte size of the transaction by spending the lowest number of UTXOs. This results in a low network fee. - Minimize future fees (merge coins), This strategy includes the maximum number of inputs so that a potential future price rise does not make smaller UTXOs economically unspendable. If the price of a crypto asset increases too much, small UTXOs may become worth less than the cost of the network fees to spend them.
  5. Select which coins may not be included in the selection by unticking their checkbox. The SELECTED indicator shows which coins will be included in the transaction. By changing the selection strategy and/or coins to include, the user has precise control over which coins end up being spent. The Coins to spend and Change to return indicators show how much is spent from and returned to the account.
  6. Click on Done to return to the Send flow to verify and send the transaction.
The coin control window lets you select the strategy as well as pick the coins. Coins marked SELECTED will be included in the transaction.

Coin status

The following statuses can be displayed for a coin:
  • Coins received in a transaction with 0 confirmations without RBF enabled: PENDING
  • Coins received in a transaction with 0 confirmations with RBF enabled: REPLACEABLE
  • Coins received in a transaction with 1337 confirmations: 1337 CONFIRMATIONS
By enabling the toggle Include coins from unconfirmed, replaceable transactions, replaceable transactions can be selected in the Coin control screen.

The Privacy use case

One of the main use cases for Coin control is to protect one’s privacy. UTXOs are, unfortunately, not perfectly fungible due to their unique history on the blockchain. Therefore, users may want to spend coins from different sources without mixing them together, because this would indicate to an outside observer of the blockchain that these addresses belong to the same account. For instance, if one were to spend coins bought on a KYC exchange, which are associated with the user’s identity, together with coins bought anonymously using cash, the anonymous coins could be linked to the user’s identity.
Another example would be that you would like to prevent spending a high-value coin for smaller purchases because this would unnecessarily show the person you’re paying how much you have. This is similar to not showing the boulanger how much is on your bank account when buying a baguette.

Let us know what you think!

We are excited to release this new feature because we think it will fulfill real needs of an important part of our users. This version of Ledger Live marks an important milestone, but we will continue working on more features that our community wants.
So, we invite you to try out Coin control in Ledger Live and let us know what you think! All feedback is welcome on this thread, on ledgerwallet, and you can send suggestions or get help through our official contact form.
We'd like to close out by underlining our commitment to the Bitcoin community, and our willingness to build the best wallet ecosystem for newbies as well as for power users.

How does bitcoin scale in performance? (CPU and RAM usage, usually ppl talk about disk space)

I am currently reading "Mastering Bitcoin" and I learned a lot of news things. But a questions keeps bugging me:
If bitcoin grows around 1 terabyte each decade (i know, this is not yet the case), that is completely fine. But the fullnodes store the whole history and validate against the whole past, right? Also wallets, that "restore from a private key" (you setup a new wallet with an old private key, so it has to check the full bitcoin history for your funds).
Won't those be extremely slow mechanisms in the future? What is bearable now, will it be super cpu-intensive in several years? The mempool takes unconfirmed transactions, but in the end, it only "accepts" them, if they are valid. So the node has to validate all of them right? The longer the chain, the longer that takes, right? (not sure if a node really validates all of them, or if he just validates the block that a miner delivers. I read conflicting information on this topic or misinterpreted one.)
Disclaimer: I could be wrong on some things, please go easy on me. :)

the year 2020 in Bitcoin Cash so far: a detailed history

the year 2020 in Bitcoin Cash so far: a detailed history
What follows at the bottom is a four page long chronological overview of what happened in BCH in 2020 so far. To make it more digestable and fun to read I start with my narrating of the story.
My attempt was to remain as objective as possible and "let the facts speak for themselve" with everything sourced. I also link to many read.cash articles, the decision of which are the important ones to include is certainly not easy, I count on the rest of the community if I overlooked anything important.

summary & my narrating of the story:
The year started out relatively calm, with cashfusion in "the news" and an older ongoing controversy between Amaury and Roger Ver being worked out. Starting Jan 22nd all debate broke loose with the announcement of “Infrastructure Funding Plan for Bitcoin Cash” by Jiang Zhuoer of BTC.TOP. To illustrate this point 2 days later coinspice ran the title " Roger Ver Praises Vigorous Debate, [...]" and 6 days, less than a week, later Chris Pacia made a read.cash post titled "The 253rd "Thoughts on developer funding" Article" which might have been only a slight exaggeration or he might have been counting. Part of the reason of the tsunami was the lack of worked out details. By the time of Pacia's post a lot had changed: Both BU, Bitcoin Verde and a group of miners had made announcements not to go along with "the plan".
On feb 1st, the second version of the IFP was announced by Jiang Zhuoer in a post “BCH miner donation plan update”. Two weeks later on Feb 15th, the third iteration was announced by Bitcoin ABC which was to be activated by hashrate voting and on the same day Flipstarter was introduced, a sign of the search for alternative solutions. After a few more days and a few more people coming out more against the IFP (including Jonald Fyookball, Mark Lundeberg & Josh Ellithorpe), BCHN was announced on feb 20th with a formal release a week later. Also feb 27th, the DAA was brought back into the conversation by Jonathan Toomim with his " The BCH difficulty adjustment algorithm is broken. Here's how to fix it." video. By early march the IFP was effectively dead with its author Jiang Zhuoer vowing to vote against it. This became clear to everyone when ABC, a day later sudddenly shifted gears towards non-protocol, donation based funding: the IFP was dead. End march ABCs 2020 Business Plan was announced as a way to raise $3.3 million. Mid april to mid may was the high time for voluntary funding with four node implementations and General Protocols, a BCH DeFi Startup successfully raising funds.
By May 15th, the 6th HF network upgrade things had pretty much cooled down. The upgraded included nothing controversial and even saw an unexpected doubling in the unconfirmed transaction chain. June 15th a month later things started to heat up again with the BCHN announcement to remove the "poison pill" or "automatic replay protection". 8th Jul Jonathan Toomim posted "BCH protocol upgrade proposal: Use ASERT as the new DAA" which promised the solution to the long dragging DAA problem. Jul 23th however an unexpected twist occurred when Amaury Séchet posted "Announcing the Grasberg DAA" an incompatible, alternative solution. This, again, sparked a ton of debate and discussion. Grasberg lasted just two weeks from Jul 23th to Aug 6th when ABC announced its plans for the november 2020 upgrade but it had successfully united the opposition in the meanwhile. ABCs plan for november included dropping grasberg in favour of aserti3–2d and introducing IFPv4. Now we're here August 8th, the IFP which was declared dead after just over a month (Jan 22-Mar 5) is now back in full force. The rest of the history is still being written but if p2p electronic cash is to succeed in any big regard it's very thinkable that these events will get into history books.

Failed transaction from 10 days ago ... re-broadcast?

I understand the mempool is jammed and transaction fees are up.
About 10 days ago I tried to self-transfer bitcoin from a hot wallet (wasabi) to hardware (using electrum). I used 1 sat/byte fee. At the time the fees had just started rising and I was ok waiting several days/weeks for it to confirm. For the first week, I could see the unconfirmed tx in both wallets.
Yesterday I noticed that wasabi put the funds back into my wallet, and the transaction was deleted from my history completely. I still see the unconfirmed inbound tx in electrum, but it says "Local". Both wallets are pointed at my own Node.
Since electrum saw the inbound transaction, is there any way to push this tx through? It seems like in wasabi I can "double spend" these funds.

I found a $600k BCH theft that has gone unnoticed

Hello all, I'm (among other things) a graduate student getting a master's degree in cybersecurity. This last quarter for one of my classes, I was tasked to examine and recreate an exploit. For the actual exploit I was examining the "anyone can spend" segwit addresses on the BCH chain, and in my research I found a $600k theft that seems to have gone completely unnoticed.
You all might recall this $600k theft of segwit addresses, but it happened again in mid-February 2018 and there has been zero news about it.
BCH block 517171 contains solely segwit-stealing transactions. If you look at any given transaction, the inputs are all segwit program hashes spending a P2SH segwit output. I only caught it by accident, as I was originally going to talk about the publicized November attack.
The interesting thing I discovered about this was that it's harder to have stolen that segwit money than most people think. Both Unlimited and ABC nodes do not relay segwit-spending transactions, and Bitcoin ABC hard-coded in fRequireStandard, so you couldn't even force-relay them with a conf option. On top of that, miners keep their node IPs private for obvious avoiding-ddos-and-sybil-attack reasons, which means it's impossible to directly send transactions to miners. This means that the only way to actually execute this attack was to setup one's own mining pool running on a custom-modified client to allow non-standard transactions. Then you'd have to get enough hash power to mine a block yourself. I estimated the cost of renting enough hash power to do this at the time as around $30k-$60k to have a greater than 90% chance of mining a block within a 3 month window.
In order to simulate the attack, I spun up BTC, LTC, and BCH nodes in Docker, and wrote a Python script. The Python script started at segwit activation on BTC and LTC and it scanned every transaction in every block looking for P2SH segwit inputs as well as native segwit outputs, since these are the necessary hash pre-images to spend P2SH segwit money on the BCH chain. The script then also scanned the BCH chain for any native segwit outputs, as well as recording all P2SH outputs. (This was all saved in a MySQL database.) Then, at any point in time, I could simply query for BCH unspent native segwit outputs as well as P2SH outputs for which I had a known segwit hash pre-image. (If this was an attack I was doing real-time, I would probably also have a large mempool on each node and monitor unconfirmed tx's for useful info as well, but since this was after the fact, I just queried blocks sequentially.)
For the mining node that runs the pool, it would need to be firewalled behind (i.e. only connected to) an unmodified node in blocks-only mode, so that the segwit hash pre-images aren't transmitted out to the network, and so that no other unconfirmed transactions are transmitted in to the mining node. (The mining node should only be filling its block with segwit tx's in order to maximize the gain from the attack.)
Then a script should run continuously to grab segwit utxos from the MySQL database and construct high-fee transactions to send directly to the mining node. Unlike the November attack, each input should be spent in its own individual transaction, so that in the event it is individually spent, I don't negate a tx with other inputs. The overhead on having different transactions for each input is only about 8 extra bytes (the tx version and the locktime), so I think this is a good trade-off.
Then, the attacker simply rents hashing power and points it at his secret pool.
By the time February rolled around and the attack happened, my MySQL database had about 40 million BCH P2SH outputs and each query took about 3 minutes to execute. This of course would have been fine in the 10-minute block world of Bitcoin and BCH, but it means that I stopped my Python script after that time, so I don't know about any possible other attacks that happened before the clean stack rule was hard-forked into BCH.
It was pretty interesting to work through how this attack must have happened, and it was significantly harder to execute than I thought it would be given that all the money was "anyone can spend".
However, the most interesting thing about all this is that nobody has noticed. There is literally no news or mention of block 517171 or any of the transactions in it. My theory is that it is money that nobody misses -- i.e. misprogrammed custom wallet software for BTC nodes accidentally also sent out BCH transactions to the same address, given that BTC and BCH shared the same history until August 2017. And whatever person or entity is running those nodes is only thinking about BTC money and is completely oblivious to its misprogrammed problem of shipping BCH to segwit P2SH addresses.
Obviously, that's just a theory, but I think it's pretty reasonable. Given the intense community divide, I think it's very possible that a number of BTC users simply ignored money on the BCH chain, even though it's "free money" for them, simply out of ideological hatred.
Whatever the case, nobody has posted anywhere complaining of money stolen in that block. It seems to have gone completely unnoticed. (Which is why I'm posting this.) It was an interesting case study and I'd be curious to hear if anybody has any addition information or thoughts about it. I believe this was a different person than the November theft, because the way it was done was different -- the November theft had all the money in one transaction, but this February theft was done with separate individual transactions. Additionally worth noting is that the address which received the bulk of the money is still active, which means they're still out there.
Anyway, I thought this was interesting and worth posting.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Did somone send me 30,000 in bitcoin?

I opened an account on silkroad 3.1, i made some purchases which arrived all fine. Then 3 days ago i go online to my account and saw that there was 2.9999999998087E-8 unconfirmed bitcoin in my wallet. I think its too good too be true and it probably is, i know that in math e-8 would set the decimal back making it worthless, But idk what this notation is representing is it possible its symbolic of a transaction fee? Or why would somone send such a small amount of bitcoin and why would the site display it in such a confusing manner? Someone please help, is this to be good to be true? Can i pay for college?
Also the site says in about that all transaction history is cleared in 14 days and to open a support ticket before if issues occur Idk if i should as to not attract attention

Unconfirmed parent?

So earlier today I transferred some bitcoin from my coinbase account to my electrum wallet. I then tried to transfer that to another wallet, but now under the history tab on electrum it just says 'unconfirmed parent'. And it also says for the transaction from coinbase to electrum 'unconfirmed', even though the bitcoin appeared in my wallet, which I then assumed was okay to send to the other wallet.

What do I do in this situation? Will the transfer go through or will I have to transfer more bitcoin? Also Should I make a new electrum wallet if I want to try transferring more?

cheers

Announcement: Symphony_IOHK Releases Symphony-Web 2.0

Announcement: Symphony_IOHK Releases Symphony-Web 2.0

View from inside a blockchain galaxy
The Symphony project began with a question: how do we represent blockchain technology in a way that is stimulating, entertaining, and audio-visually engaging for a wider audience, technical and non-technical. In other words, how do we explain the abstract and give form to the formless.

It’s been over a year since we answered that question, and we’re still working to make Symphony the most interactive and immersive blockchain experience available. What began as a way to visualize the blockchain has evolved into a way to experience the blockchain: an immersive journey accessible through your device’s browser.

The result is Symphony 2.0: a 3D explorer through which anyone can traverse the topographic history of the Bitcoin blockchain, from the first transaction to the most recent. Compared with the first version, Symphony 2.0 goes deeper in every way. It drills down into transaction data to create a live soundscape – each block has its own unique audio signature – using data-driven sound synthesis. It looks like this:


Soar over the galaxies of blockchians

How it Works

As you can imagine, giving feeling to data isn’t easy. Creating a sound for each block was how I wanted to represent the uniqueness and permanence of the blockchain: once added, a block is there forever, making that same sound, containing those same transactions.

I used a technique called additive synthesis to generate sound on the fly, and utilized the parallel nature of graphics cards to synthesize a unique sound for each of the thousands of transactions that can make up a block. The sound signature that plays when you visit a block consists of each transaction producing eight sine waves (a fundamental pitch and seven harmonics). The fundamental pitch is determined by the transaction value, and the amount of randomness added to the harmonics partials is controlled by the fee-to-value ratio of the transaction.

https://preview.redd.it/w6be8pwjb5931.png?width=1114&format=png&auto=webp&s=856bbc3572cf535a35ea20a086daa467e6512e8e

Design Philosophy

With Symphony 2.0, the blockchain’s mempool – which stores unconfirmed transactions – is visualized as a gravitational swell, around which confirmed transactions spiral in concentric rings. Think of Saturn’s rings but, instead of particles of ice and rock, we have transactions, continuously adding to the size of the rings as they extend outwards. Then, undergirding each block are Merkle trees represented, unsurprisingly, as trees.

https://preview.redd.it/exoldf4lb5931.png?width=1120&format=png&auto=webp&s=07c632b930131b94b4852293bfe6272b4a9ef90f
On top of each block, confirmed transactions are visualized as 3D hexagons. Their height corresponds to the transaction volume, and their width (note the rotund individuals to the right of the image above) corresponds to the health of the block. The result is an unprecedented imagining of the blockchain, with its representative parts synced and manifest, explorable block-by-block or through a flight-simulator mode.

Ways to Experience Symphony

Symphony 2.0 is now live It can be accessed using any modern web browser, but is best experienced in Google Chrome. For laptop and mobile device users, it’s advised to select the Medium quality option and, for those with high-performance devices or dedicated graphics support, the High quality option. Performance optimizations will continue into the future.

Together with our friends at Kuva, a Bristol-based creative agency, we’ve also grown the project to include events and exhibition pieces. These events – one of which was held this year in Bristol – have included a number of exhibitions that showcase different parts of the project, including virtual reality (VR) and augmented reality (AR).

Using WebVR software, I built a VR experience based on the code for Symphony 2.0, which demonstrates the extensibility of the system. This will be exhibited at future events and, I hope, one day available for VR headsets at home.

What’s Next

We’re going on tour. We have the story, and now we need an audience. I’m also starting to build an Ethereum version using the same code base, which will feature explorable smart contracts, and, after that, Cardano. We know there are thousands of people out there who are only faintly familiar with blockchain technology and want to know more – and with Symphony 2.0, they’ll be able to cut through the confusion. A picture tells a thousand words, and an interactive audio-visual experience tells many more.

Symphony is a long-term project. It’s as much an adventure for us as our audience. We want to see how far we can take it – because blockchain technology is still developing, still growing, and the opportunity for education is only just beginning. The release of Symphony 2.0 marks a significant milestone for us, and we’re thrilled to be sharing it with you. There’s a lot of opportunity for Symphony, from optimizations and incorporation of other blockchains, to events and more ways to enjoy Symphony at home. So, stay tuned for more updates and, in the meantime, enjoy the world’s first interactive blockchain experience.

Community. We need to upvote this post so no one else loses money!

This is a seriously important topic everyone is ignoring. Copay / Bitpay wallet has been having problems with their servers. In long story short. TONS of transactions have just gone missing from users across the world. If you go onto the copay help and support forum, there's tons of new topics of people losing funds or them being in limbo in copays system. I have lost over 3k and support is ignoring everyone's tickets... How is no one talking about this ?
EDITED TO INCLUDE BACKSTORY FROM BELOW:
So on December 9th in my copay wallet right now, I am sending out 0.043239 BTC with a fee of 0.000243btc to address : 1LqRQgKFDKfm6za8q6esdU2yFYe1zngqJc with tx : 83309d5858cf226c3c0edd360c36a2c0c059db3da3a3582f47df6cd468bf2f80
Yes I understand this was a low fee, but I send transactions ranging from 400 sat/byte to 80 sat/byte depending on the situation.. it still should have been picked up on the blockchain and in the mempool at 88 sat/b
The reciever who is my brother, has the funds recieved into his wallet. Yet this transaction is not on the blockchain. When I view the transaction in copay it directs me to bitpay insight, which then states transaction does not exist. If I paste this tx into any block explorer it doesn't exist, and if I paste the address of my brother who is recieving the funds, on the blockchain, it says there has been no recieved Bitcoin to the address. On top of this, the balance that was sent out keeps appearing and revanishing in my wallet as if it is there for a second and then disappearing, as well as in my transaction history. I have screenshots and can demonstrate how there is something wrong with copay. This has nothing to do with the mempool.
My transaction did not even touch down in the mempool, but the balance sent out of my copay ? How does this make any sense.. The representative on the copay board keeps going in circles that he encourages us to paste a txid that isn't even real into a blockexplorer other than bitpay insight.. he is also closing all tickets without resolving this problem. By hand i can count 20 people with this issue. Someone even lost 9 btc. This is ridiculous.
Please do not give me the answer that the mempool is too full or this transaction does not exist.. because it does exist, and I'm missing a total of $1500 usd from my wallet which I can view as sent out but unconfirmed and not touching down on the blockchain. I have years of experience in this industry as well as run a business around it. I am familiar with fees / acceleration as well as bumping. And this is not something anyone should be dealing with. Where is my money and how are you going to resolve this.
Here is another user who lost 3 btc with copay with similar issues.. no one is talking about this...

IOTA Definition

IOTA Definition
History of IOTA
The blockchain was announced in October 2015 through. The roots of IOTA go back to the Jinn project. That project aimed to develop ternary hardware or low-cost and energy-efficient hardware, primarily general-purpose processors, for use in the IoT ecosystem. Jinn held a crowd sale for its tokens in September 2014. The Jinn tokens were soon in hot water because they marketed as profit-sharing tokens.. In 2015, Jinn was rebranded as IOTA, and another token sale was held. This time around, the tokens were marketed as utility tokens, and Jinn token holders could exchange their tokens at equivalency with the new blockchain. According to David Sønstebø, IOTA was “spawned” due to the Jinn project. But reports state that a snapshot of the genesis transaction is yet to be found online. These tokens were dispersed to other “founder” addresses. The total number of mIOTAs planned to be in existence is 27 quadrillion. According to IOTA’s founders, the total number of mIOTAs fits in “nicely” with the maximum allowable integer value in Javascript, a programming language.
Understanding IOTA
According to research firm Gartner, there will be 20.4 billion devices connected to the Internet by 2020. Within this ecosystem, each device will exchange data and payment information with multiple, other devices in transactions conducted throughout the day. IOTA intends to become the standard mode of conducting transactions on devices. Its founders have described the ledger as a “public permission-less backbone for the Internet of Things that enables interoperability between multiple devices.” In simple words, this means that it will enable transactions between connected devices, and anyone will be able to access it. Those problems are primarily caused due to a backlog of transactions on Bitcoin’s blockchain. The backlog itself is because of a variety of reasons, from small block sizes to the difficulty of puzzles that miners must solve to earn the cryptocurrency as a reward. IOTA solves these problems by reconfiguring blockchain's architecture into Tangle, a new way of organizing data and confirming transactions.
How Does IOTA Solve Bitcoin’s Scalability Problems?
IOTA’s solution to Bitcoin’s problems is to do away with several key concepts and topographical constraints of a blockchain. mIOTA, IOTA’s cryptocurrency, is pre-mined and consensus of transactions occurs differently as compared to a blockchain. IOTA developers have proposed a new data structure. Tangle is a Decentralized Acyclic Graph, a system of nodes which is not sequential. Thus, each node can be connected to multiple other nodes in a Tangle. But they are connected only in a particular direction, meaning that a node cannot refer back to itself. A standard blockchain is also a DAG because it is a sequential linked set. In Bitcoin, a group of systems running full nodes that contain the entire history of transactions for a ledger are required for confirmations and consensus. Full node miners are not required in Tangle. Each new transaction is confirmed by referencing two previous transactions, reducing the amount of time and memory required to confirm a transaction. Related to the concept of a “confidence” is a transaction’s weight. As it moves through Tangle, a transaction gathers weight. A transaction’s weight increases with the number of approvals. Once a transaction is confirmed, it is broadcast to the entire network, and another unconfirmed transaction can choose the newly-confirmed transaction as one of the tips to confirm itself.
Governance Protocol
IOTA has not outlined a governance structure for its blockchain. The IOTA Foundation is primarily responsible for funding and leading development of IOTA. In a previous post, John Licciardello, former managing director of IOTA's Ecosystem Development Fund (EDF), that would allow members of the IOTA community to vote on proposals regarding its future direction. But there are no updates on the initiative yet.
Concerns About IOTA
Criticism of IOTA has mainly centered around its technical flaws. As with most cryptocurrencies, IOTA’s system is nascent and unproven. A phishing attack on its network resulted in the theft of mIOTA worth $3.94 million. In other words, they created their encryption scheme from scratch, forgoing the widely-used SHA-256 hash function used in Bitcoin. The team at MIT’s Digital Currency Initiative found serious vulnerabilities with IOTA’s hash function, which is called Curl. This property is known as Collision and denotes a broken hash function. In their analysis of the vulnerability, the MIT team stated that a bad actor could have destroyed or stolen user funds from Tangle with their technique. IOTA’s team has corrected the vulnerability. The foundation announced a new partnership with Ledger, one of the leading producers of hardware wallets. IOTA technology will be integrated into the hardware wallets, giving users the ability to store the private key information in a device that adds another layer of protection from hackers.
https://preview.redd.it/ex768bb74gw31.jpg?width=777&format=pjpg&auto=webp&s=4e89f0875410274a85b76227c17d321b5c3d29ed
“The collaboration between the teams created an immediate synergy concentrated on developing a compatibility feature allowing users to access, store and manage IOTA tokens on Ledger devices. 

The IOTA (MIOTA) digital asset suffered from a lack of adequate wallets for months, even at the peak of the market. The asset, which commanded prices above $5, was not spared by the bear market. Despite the launch of the long-awaited Trinity wallet, MIOTA lost positions. Given that mIOTA, the crypto used in IOTA, is still to gain mainstream traction, its claims to eliminate scalability problems for blockchains through the use of DAGs are also still to be proven. Vitalik Buterin, the co-founder of Ethereum, has cast doubt on the ability of hashgraphs to solve scalability issues.
Another problem with IOTA currently is the small size of its network. Researchers have found that hackers need only gain control of 33% of the total hashing power required to bring it down. In Bitcoin, control of 51% of a network is required to bring its blockchain down. To ensure security, IOTA’s network currently uses a central server known as a Coordinator to process transactions. This practice has diluted its claims of being a decentralized system since the introduction of a Coordinator has resulted in the introduction of a single point of failure.
The consensus system is described in a new white paper. In the past, IOTA has been criticized for its hidden centralization, as well as for the loss of coins sometimes happening when a user’s wallet was unable to receive its previous balances from the state of the Tangle.
But despite the innovation, IOTA lags behind digital assets that are receiving the most significant inflows of investment and trading liquidity.

[Weekly Report] BSV News

Dear friends of LivesOne,
Since the Symbiosism Economy Foundation announced the cooperation with BSV, we have introduced BSV in detail, including its history, philosophy, advantages, and the reasons for our choice. LivesOne always pays close attention to the trend of BSV and informs you in time. As we enter the year 2020, good news is coming one after another.
Mining pool reduces BSV transaction fee and anchors legal tender
BSV transaction fees are already the cheapest in major blockchains, but this is not enough. On January 8, the famous Bitcoin mining giant TAAL announced that in order to support blockchain applications that require a large number of transactions, it will reduce the miner rate on the BSV chain and increase the limit value of unconfirmed inherited transactions. Subsequently, the CoinGeek mining pool also issued a statement saying that it would follow up with this adjustment. Any fee reduction will send a clear signal to the market that the cost of using BSV will decrease. It is expected that this change will incentivize more enterprise applications to generate a large number of BSV transactions. Taking this step will generate high transaction volumes and higher total transaction fees.
At present, Bitcoin transaction fees are not expressed in legal tender, but in "sat / byte". Therefore, transaction fees in legal tender price will fluctuate with the fluctuation of the price of bitcoin. This fluctuation will have a greater impact on applications that generate a large number of transactions on the blockchain. Commercial users of the BSV ecosystem have recently begun to explore an alternative transaction fee model that can be priced in legal tender, which provides higher reliability for BSV business applications. This new type of expense market emerged with the greater data and microtransaction capabilities of BSV. However, this is unlikely to happen on the bitcoin core network, because its block is too small, resulting in high transaction costs.
Large enterprises usually want to be able to predict their costs, so stable transaction fees are expected to attract more enterprises to use BSV for data applications. TAAL promises to regularly check the lower BSV transaction fees to maintain stable transaction fees in legal tender. As one of BSV's partners, it is undoubtedly brought real benefits to LivesOne.
Oppose Anonymity and Embrace Regulation
The European Union’s 5th Anti-Money Laundering Directive (5AMLD) came into effect on January 10. The regulation was entered as law on July 9, 2018 in an effort to bring increased transparency to financial transactions for pushing back against money laundering and terrorist financing across Europe. For the first time, 5AMLD is broadening its regulatory scope by including crypto service providers like virtual-fiat exchanges or custodian wallet providers. The idea is make it more plainly knowable who’s participating in crypto transactions. The rationale is that doing so pushes back against money laundering and terrorism financing.
According to an 5AMLD fact sheet, the law will:
European Union is paying close attention to cryptocurrency and has established its first set of rules for how companies in this space must behave. Now it’s on those companies to gain compliance or risk being able to operate at all.
This reminds me of Dr. Craig's emphasis on the existence of BSV: Bitcoin's system should be transparent. It should not be used to fight the government; it should not be used to fight anyone. It can be used for creation, it can be used for construction. I have to say that the vision of BSV is prescient and correct. BSV is an honest system with transparency as its key feature. BSV can be used to create a more secure and honest society.
BSV with unlimited expansion, anti-anonymity, and embrace supervision is the first choice for LivesOne team cooperation. The collaboration between LivesOne and BSV is ongoing, let us look forward to seeing more details.

Long live decentralized bitcoin(!) A reading list

Newbs might not know this, but bitcoin recently came out of an intense internal drama. Between July 2015 and August 2017 bitcoin was attacked by external forces who were hoping to destroy the very properties that made bitcoin valuable in the first place. This culminated in the creation of segwit and the UASF (user activated soft fork) movement. The UASF was successful, segwit was added to bitcoin and with that the anti-decentralization side left bitcoin altogether and created their own altcoin called bcash. Bitcoin's price was $2500, soon after segwit was activated the price doubled to $5000 and continued rising until a top of $20000 before correcting to where we are today.
During this drama, I took time away from writing open source code to help educate and argue on reddit, twitter and other social media. I came up with a reading list for quickly copypasting things. It may be interesting today for newbs or anyone who wants a history lesson on what exactly happened during those two years when bitcoin's very existence as a decentralized low-trust currency was questioned. Now the fight has essentially been won, I try not to comment on reddit that much anymore. There's nothing left to do except wait for Lightning and similar tech to become mature (or better yet, help code it and test it)
In this thread you can learn about block sizes, latency, decentralization, segwit, ASICBOOST, lightning network and all the other issues that were debated endlessly for over two years. So when someone tries to get you to invest in bcash, remind them of the time they supported Bitcoin Unlimited.
For more threads like this see UASF

Debunked: "Fast transactions using 0-conf were never safe in Bitcoin. Satoshi added Replace-by-Fee himself and said we shouldn't use unconfirmed transactions."

In the Bitcoin design — today implemented in the form of Bitcoin Cash — the blockchain is used to "confirm" or "timestamp" whichever transaction sent by the same party came first. This prevents cheating, which can otherwise be done by replacing a transaction going to a merchant with one going to another or back to the payee themselves. A transaction waiting in line to be timestamped is called 0-conf and can be used to facilitate instant transactions at lower fraud rates than credit cards.
The incentives needed for the above mode of operation is derived from Proof-of-Work, which in combination with protocol and client settings creates the positive pull needed to ensure that it is always more likely that nodes will only accept the first transaction that they saw and record it in a block as soon as possible. Like everything in Bitcoin it can never be fully guaranteed, but it can be considered "reasonable certain", which is also what we see in practice.
Sources 1, 2, 3, 4
Replace-by-Fee being enabled by default in Bitcoin Core clients made 0-conf in particular much less secure on its chain, because the change of expectations that it brought in practice changed the "first seen" rule to a "highest-bid-until-it-gets-into-a-block" rule.
It did this by making it much more likely that a payee marks his transaction for potential later changes to the recipient field in the form of a replacement transaction with increased fee, in turn complicating the receiving process for merchants and making the nodes (solo-miners and pools) that run the timestamping service less strict with the first seen rule in general.
Some have claimed Satoshi invented this form of RBF and that it was present in Bitcoin from the start. These are actually complete lies. Satoshi never supported such a feature. He once had something vaguely similar in mind, but removed it to improve security. In a forum post he also explained that a replacement transaction must be the exact same as the original transaction except with a higher fee, which would of course not in any significant way allow tempering with the order in which transactions were accepted by the network.
Sources 1, 2
Bitcoin always had 0-conf. The first seen rule is essential to Bitcoin and the only way to have fast transaction speeds and immediately re-spendable coins; the security of which can then be improved on with a payment processor if one wants to or by waiting for the "confirmation" which will be "computationally hard" to reverse.
Source
Satoshi himeself was a big proponent of 0-conf payments and expected them to work fine for paying many if not most merchants. He just went out of his way to explain their drawbacks in a rather immature network and how they could be used more safely. He also did serious work to make them function as well as they could.
Sources 1, 2, 3, 4
0-conf transactions on Bitcoin Cash with 1 sat/byte or more in fees are safe enough for most use cases today, including commercial transactions. You can pay for digital goods online and have them delivered without having to wait for your transaction to confirm. With a high degree of certainty, it will eventually. Timestamping happens on average once every 10 minutes and the BCH chain being congestion free ensures it won't take days to make the transaction actually computationally hard to reverse.
In order to have close to zero risk, businesses can still wait for 1 confirmation if they so choose. Earlier in Bitcoins history it would have been more than one and over time the risk will tend to decrease as the strength of the network and the stakes of the nodes in the network itself increases. This is all Satoshi stuff.
It should be noted that Satoshi did temporarily limit the spending of such unconfirmed transactions received from a different wallet, in the reference client itself, since these — especially back then — were less secure by not yet being included in a block and passing them on too quickly actually risked breaking your wallet. This is however not a valid argument to reject the viability of 0-conf itself or to stop improving on the concept.
