The company announced that some of its digital currency wallets have been "compromised. It is the second major theft of cryptocurrencies to take place in recent days. So-called 'warm' or 'hot' digital wallets are usually based online and designed to allow users to access their cryptocurrencies more easily, while 'cold' wallets are offline and harder to access and therefore usually more secure. Liquid has said that it was tracing the movement of the stolen cryptocurrencies and working with other exchanges to freeze and recover the assets.

Talk:Bitcoin/Archive 10

Bitcoin is the original cryptocurrency released in as open-source software. It is a digital currency predicated on cryptographically secure transactions, a proof-of-work consensus model, and a decentralized, P2P distributed ledger network.

Bitcoin is a decentralized medium of exchange, high-value settlement layer, and store of value that exists outside of the traditional financial system.

The network is entirely P2P, and there are no intermediaries or centralized control. Since its inception, Bitcoin has fueled the growth of an entire industry of cryptocurrencies.

Many of these currencies are forks of the Bitcoin protocol while others have developed into full Turing-complete smart contracts platforms. Despite the wild west like atmosphere within the broader cryptocurrency industry and often polarizing nature of the communities, Bitcoin has emphatically remained resilient. With a decade of experience under its belt, the legacy cryptocurrency has shown a penchant for conservative change that has led to remarkable stability, decentralization, and transparency in spite of the criticisms it has faced over the course of its existence.

Bitcoin has emerged as an exceptional technological feat, and its future implications along with the growing industry it sparked are profound. The genesis block — launching the Bitcoin mainnet — was mined on January 3rd, with a reward of 50 BTC Bitcoin ticker symbol and a text message embedded in the coinbase transaction:.

The message was a headline pulled from the British newspaper The Times following the Global Financial Crisis of where banks were bailed out by their respective governments i. The comment is derived from the instability of the fractional-reserve banking system in general. The headline symbolizes the widely accepted concept behind Bitcoin, an immutable, uncensorable, and decentralized medium of value exchange free of the endemic problems within traditional financial systems and governments.

Satoshi Nakamoto was active on email threads, community forums, and the open-source Bitcoin repo for a little more than a year after initially releasing the white paper and went dark in December The Nakamoto Institute provides a comprehensive compilation of emails, forum posts, code updates, and other interactions that people had with Satoshi Nakamoto. Read: Who is Satoshi Nakamoto?

We Look at The Possible Candidates. Notably, Gavin Andresen was a lead core developer and created the Bitcoin Foundation in to support the development of the network. Over the years, Bitcoin has experienced innumerable contributions from the open-source community and members of the core development team. Currently, Wladimir J. In , WikiLeaks began using Bitcoin following a lack of options for receiving other currencies stemming from pressure by the U. Satoshi Nakamoto was against the notion of WikiLeaks using Bitcoin as it would draw unwanted attention from governments to a network that was still in its nascent stages and susceptible to attack.

Throughout and Bitcoin saw adoption by BitPay — the Bitcoin payment processor — and WordPress as use for payment for the service. The year was eventful for Bitcoin as popular exchange Coinbase started gaining traction at the time, after being founded in Gox exchange.

In February , the largest Bitcoin exchange — Mt. Gox — shut down due to technical issues. Soon after, the exchange filed for bankruptcy following the loss of roughly , BTC that had been stolen in an extended hack. Major cryptocurrency exchange Bitfinex was hacked in for nearly , BTC. Along with the Mt. The events in launched Bitcoin into the mainstream and the broader cryptocurrency industry along with it.

The surge in mainstream activity of Bitcoin led to a series of issues with a backed up mempool, high fees, and general frustration with using the network for payments.

At the protocol level, SegWit was also introduced in late as a method for helping increase the efficiency of digital signature storage within blocks and alleviate some of the scaling concerns. This year has had several significant and intriguing developments for Bitcoin. Moreover, the growth of the LN is gaining steam and services and applications built on top of it are helping foster greater adoption of Bitcoin as a bidirectional micropayments medium.

Privacy-preserving solutions such as Dandelion , security and privacy-focused wallets like Samourai , and self-sovereign payment processing tools like BTCPay server have become vital tools for retaining the initial vision of Bitcoin as an uncensorable, private, and secure medium of value exchange.

Bitcoin has an ample design space, and the future development on top of the core protocol could leverage Bitcoin as an immutable and secure settlement layer. Optimism may be fading in the markets, but these downturns are often touted as crucial periods of development of both the core community and underlying technology. Bitcoin has also seen widespread — in the purview of legacy finance — acceptance as at least an alternative financial asset.

While statements from banks and financial executives mostly still miss the core concept of Bitcoin, the fact that it is accepted and pegged for listing on major financial platforms as an ETF is an enormous step in general awareness from its humble cypherpunk beginnings.

Bitcoin is a permissionless, open-source cryptocurrency network maintained by a community of contributors via its BIP proposal system. The network is secured via a proof-of-work PoW consensus mechanism — known as Nakamoto Consensus —, is decentralized, cryptographically secured via the ECDSA digital signature scheme, and utilizes an unspent transaction output UTXO transaction scheme.

Game theory mechanics also play a prominent role in the network, and its technical design is rolled into the larger dynamics of the incentive system. Bitcoin employs an abstract transaction model optimized for security and linkability known as the unspent transaction output UTXO scheme.

All transactions are chained together where bitcoins actually move from transaction to transaction in the form of inputs and outputs rather than to and from addresses.

Transactions function as a chain of digital signatures. Owners transfer BTC to another owner via digitally signing the hash of a previous transaction along with the public key of the recipient and adding them to the end of the transaction.

Recipients — as is inherent with cryptographic signatures — can trivially verify the validity of the chain of digital signatures used to send the BTC. Therefore, inputs of a Bitcoin transaction end up as outputs which are then spent as inputs in an ongoing process. Users effectively do not own actual BTC; instead, they own the right to spend to a specific number of outputs.

The UTXO model in Bitcoin also allows transactions to be processed in parallel since they refer to independent inputs.

The mempool of Bitcoin are the transactions waiting to be confirmed on the network. Bitcoin only handles roughly 5 — 6 transactions per second TPS on-chain, so transactions that are not processed immediately reside in the mempool until they are picked up by miners and included into blocks. A backlogged mempool was a major problem at the height of the cryptocurrency frenzy towards the end of where it led to exceptionally high fees and slow confirmation times.

Bitcoin also has a native, stripped down scripting language for implementing payment functionality. The proliferation of applications, sidechains, and other technical components with Bitcoin has led to an increase in the use of the scripting language for specific payment functionalities.

Bitcoin is the original blockchain. A new block is mined by miners roughly every 10 minutes, and blocks are usually 1 — 1. Transactions broadcast to the network are incorporated into blocks by miners in a process called Nakamoto PoW Consensus outlined in the next section which validates the transactions and secures them via computational work. The original block was the Genesis block mined by Satoshi Nakamoto and contained the text message within the coinbase transaction.

The coinbase transaction is the first transaction in a block that is created by the miner and allows them to claim the block reward for mining the block as well as bytes for arbitrary data. Transactions contained within blocks are continually hashed and paired in a binary hash tree known as a Merkle Tree until the root hash is reached, which represents all of the transactions in the block and is stored in the block header.

Each block stores the root hash of the previous block, thus cryptographically linking all of the blocks, hence the name blockchain. The ledger of blocks is entirely public, transparent, and digitally timestamped.

The root hash of the current block header represents the state of the entire Bitcoin blockchain, from the Genesis block up to the current block. Transactions within a block cannot be modified without modifying all of the transactions within that block as well as all of the following blocks due to the cryptographic linkage of the Merkle roots between blocks. This gives Bitcoin its immutability property. Full node clients store the entire blockchain locally and propagate transactions across the network.

Further, they assist new nodes in catching up to the state of the Bitcoin blockchain and provide the necessary data for SPV nodes to function correctly. SPV nodes are light clients called Simple Payment Verification nodes and do not store the entire blockchain. Rather, they rely on full nodes to provide them with an accurate picture of the blockchain. An experimental version of a new light client protocol called Neutrino was recently proposed and is being developed by Lightning Labs.

Naturally, in a decentralized P2P network of pseudonymous users, the inherent problem arises of how to ensure that the state of the blockchain is accurate. Overcoming this issue means ensuring, with extremely high probability, that the transactions included in mined blocks are not double spent. This is one of the major achievements of Bitcoin as it solved the double spend problem using a computationally intensive proof-of-work model called Nakamoto Consensus.

Proof-of-work PoW consensus is what was proposed by Satoshi Nakamoto as a method to implement a distributed timestamped server blockchain on a P2P basis. Nodes are free to join and leave the network anonymously at will, so it needs to handle arbitrary behavior by malicious nodes. Read: What is Nakamoto Consensus? The point of PoW consensus is to make it costly — from a computational resource perspective — to mine a block, with the tangible cost coming in the form of electrical energy expended to produce the computation attempting to mine the block.

One of the essential passages from the original Bitcoin white paper that lays the foundation for PoW consensus in Bitcoin and its overall security is:. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If a majority of CPU power is controlled by honest nodes, the honest chain will grow the fastest and outpace any competing chains.

To modify a past block, an attacker would have to redo the proof-of-work of the block and all blocks after it and then catch up with and surpass the work of the honest nodes. A work difficulty targeting an average of 6 blocks per hour is based on a moving average to ensure the timely mining of blocks while compensating for increasing hardware speed.

The resulting PoW model relies on the security assumption that a significant amount of work was invested into mining a block. Also it assumes that the majority of nodes in the network are not compromised due to the massive incentive to NOT compromise the chain as well as general pBFT assumptions based on the probability of arbitrary node behavior. The miner that wins the block subsequently broadcasts the block to its peer nodes who propagate the block across the network for confirmation among the nodes.

Once the block is confirmed, the round restarts and transactions are included into candidate blocks by miners until one finds the nonce value. The higher up the blockchain block height , the more unlikely it is to change a block below the current height. The general assumption is that it is computationally infeasible to modify a block in Bitcoin after 6 block confirmations on top of that block.

Miners invest substantial amounts of capital into hardware equipment to mine Bitcoin , and their rewards for doing so are directly in Bitcoin. The game theoretics of the system are designed so that attempting to attack the network is unsustainably costly. However, the odds of sustaining a 51 percent are extremely low, and the net result is not worth the costs. According to GoBitcoin.

Mining is the only way to produce Bitcoin. Due to the halving of the reward every , blocks, Bitcoin is a deflationary currency since there will only ever be 21 million BTC in existence.

As a result, the final BTC will be mined in the year

Confessions of a Bitcoin sceptic

In this article, we will like to go back to the main stages in the history of the King of Cryptocurrencies, still less known, but we are sure it will become a benchmark to many investors and digital currencies users in the next years. In this article we will try as much to highlight the most significant events in the history of currency, from its origin to present date, highlighting the main stages. The origins of Bitcoin, at least from what we know, dating back to August , when the Bitcoin. This is only the first step, designed to anticipate the publication of the Bitcoin Technical Report, signed by Satoshi Nakamoto.

Shouldn't there be a section that deals with how Bitcoin is "supposed" to work relative to traditional currency concepts, in particular "Money Supply? In this connection it might be helpful to explore at some length the analogy with gold as a currency. After reading some of the references one can gather that there will be a diminishing creation of bitcoin although you can't see it yet in the blockchain numbers up to a fixed maximum, again like gold. Are there ways in which the analogy to gold works and doesn't work? Lots of economists seem to have written about this but there is very little in the article. Bluepost22 talk , 20 November UTC.

If you did not know Steam has introduced support for online game purchases with Bitcoin in April last year , allowing users of the crypto currency to quickly and easily spend it for software. The payment processor that Valve is using for accepting Bitcoin payments is BitPay. Once you select Bitcoin as the payment method you are presented with a QR code to scan to do a payment with a mobile device or you can just copy and paste the BTC address and the amount of coins you need to send to complete the payment. You have 15 minutes to initiate the transaction and as soon as you send the coins and the transaction gets broadcasted over the network the payment is accepted, no need to wait for a minimum of 6 confirmations or anything like that. Valve has officially added support for Bitcoin payments in their Steam platform for distributing games online, meaning that millions of gamers worldwide can now pay with BTC for their new game purchases. There has been some rumors and leaks suggesting that this will happen at some point, but it is official now and you can already pay with Bitcoin at Steam.

All the history is related to Bitcoin. Now I've learned a bit about using git, github, jamstack, I figured that I will make this repository content first, and add it as a submodule to bitcoinfo. This is a copy of Bitcoin-history. Shortly I'll be diving deeper into the history of bitcoin itself. Thusfar, I've been circling around it, so to speak.

Gox agitated for proof that the Tokyo-based firm was still solvent after a hacking attack, CEO Mark Karpeles turned to the comedy science fiction novel "The Hitchhikers Guide to the Galaxy". The gesture - with a sly wink to the "geek" culture Karpeles believed he shared with many of his 50, customers at the time, including an interest in coding, Japanese manga comics and science fiction - succeeded. By moving , bitcoins, Karpeles, then 26, evoked the random number, 42, described as the "meaning of life" in Douglas Adams' sci-fi novel. But even as Mt.
