A blockchain is a growing list of records , called blocks , that are linked together using cryptography. The timestamp proves that the transaction data existed when the block was published in order to get into its hash. As blocks each contain information about the block previous to it, they form a chain, with each additional block reinforcing the ones before it. Therefore, blockchains are resistant to modification of their data because once recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks.
Blockchains are typically managed by a peer-to-peer network for use as a publicly distributed ledger , where nodes collectively adhere to a protocol to communicate and validate new blocks. Although blockchain records are not unalterable as forks are possible, blockchains may be considered secure by design and exemplify a distributed computing system with high Byzantine fault tolerance. The blockchain was popularized by a person or group of people using the name Satoshi Nakamoto in to serve as the public transaction ledger of the cryptocurrency bitcoin , based on work by Stuart Haber, W.
Scott Stornetta, and Dave Bayer. The implementation of the blockchain within bitcoin made it the first digital currency to solve the double-spending problem without the need of a trusted authority or central server.
The bitcoin design has inspired other applications   and blockchains that are readable by the public and are widely used by cryptocurrencies. The blockchain is considered a type of payment rail. Private blockchains have been proposed for business use. Computerworld called the marketing of such privatized blockchains without a proper security model " snake oil ";  however, others have argued that permissioned blockchains, if carefully designed, may be more decentralized and therefore more secure in practice than permissionless ones.
Scott Stornetta. In , Haber, Stornetta, and Dave Bayer incorporated Merkle trees to the design, which improved its efficiency by allowing several document certificates to be collected into one block. The first decentralized blockchain was conceptualized by a person or group of people known as Satoshi Nakamoto in Nakamoto improved the design in an important way using a Hashcash -like method to timestamp blocks without requiring them to be signed by a trusted party and introducing a difficulty parameter to stabilize the rate at which blocks are added to the chain.
In August , the bitcoin blockchain file size, containing records of all transactions that have occurred on the network, reached 20 GB gigabytes. The ledger size had exceeded GB by early The words block and chain were used separately in Satoshi Nakamoto's original paper, but were eventually popularized as a single word, blockchain, by According to Accenture , an application of the diffusion of innovations theory suggests that blockchains attained a A blockchain is a decentralized , distributed , and oftentimes public, digital ledger consisting of records called blocks that is used to record transactions across many computers so that any involved block cannot be altered retroactively, without the alteration of all subsequent blocks.
They are authenticated by mass collaboration powered by collective self-interests. The use of a blockchain removes the characteristic of infinite reproducibility from a digital asset. It confirms that each unit of value was transferred only once, solving the long-standing problem of double spending.
A blockchain has been described as a value-exchange protocol. Logically, a blockchain can be seen as consisting of several layers: . Blocks hold batches of valid transactions that are hashed and encoded into a Merkle tree. The linked blocks form a chain. Sometimes separate blocks can be produced concurrently, creating a temporary fork.
In addition to a secure hash-based history, any blockchain has a specified algorithm for scoring different versions of the history so that one with a higher score can be selected over others. Blocks not selected for inclusion in the chain are called orphan blocks. They keep only the highest-scoring version of the database known to them. Whenever a peer receives a higher-scoring version usually the old version with a single new block added they extend or overwrite their own database and retransmit the improvement to their peers.
There is never an absolute guarantee that any particular entry will remain in the best version of the history forever. Blockchains are typically built to add the score of new blocks onto old blocks and are given incentives to extend with new blocks rather than overwrite old blocks.
Therefore, the probability of an entry becoming superseded decreases exponentially  as more blocks are built on top of it, eventually becoming very low. There are a number of methods that can be used to demonstrate a sufficient level of computation. Within a blockchain the computation is carried out redundantly rather than in the traditional segregated and parallel manner.
The block time is the average time it takes for the network to generate one extra block in the blockchain. Some blockchains create a new block as frequently as every five seconds. In cryptocurrency, this is practically when the transaction takes place, so a shorter block time means faster transactions.
The block time for Ethereum is set to between 14 and 15 seconds, while for bitcoin it is on average 10 minutes. A hard fork is a rule change such that the software validating according to the old rules will see the blocks produced according to the new rules as invalid.
In case of a hard fork, all nodes meant to work in accordance with the new rules need to upgrade their software. If one group of nodes continues to use the old software while the other nodes use the new software, a permanent split can occur. For example, Ethereum has hard-forked to "make whole" the investors in The DAO , which had been hacked by exploiting a vulnerability in its code. In this case, the fork resulted in a split creating Ethereum and Ethereum Classic chains.
In the Nxt community was asked to consider a hard fork that would have led to a rollback of the blockchain records to mitigate the effects of a theft of 50 million NXT from a major cryptocurrency exchange. The hard fork proposal was rejected, and some of the funds were recovered after negotiations and ransom payment. Alternatively, to prevent a permanent split, a majority of nodes using the new software may return to the old rules, as was the case of bitcoin split on 12 March By storing data across its peer-to-peer network , the blockchain eliminates a number of risks that come with data being held centrally.
Peer-to-peer blockchain networks lack centralized points of vulnerability that computer crackers can exploit; likewise, it has no central point of failure. Blockchain security methods include the use of public-key cryptography.
Value tokens sent across the network are recorded as belonging to that address. A private key is like a password that gives its owner access to their digital assets or the means to otherwise interact with the various capabilities that blockchains now support. Data stored on the blockchain is generally considered incorruptible. Every node in a decentralized system has a copy of the blockchain.
Data quality is maintained by massive database replication  and computational trust. No centralized "official" copy exists and no user is "trusted" more than any other. Messages are delivered on a best-effort basis. Mining nodes validate transactions,  add them to the block they are building, and then broadcast the completed block to other nodes.
Open blockchains are more user-friendly than some traditional ownership records, which, while open to the public, still require physical access to view. Because all early blockchains were permissionless, controversy has arisen over the blockchain definition. An issue in this ongoing debate is whether a private system with verifiers tasked and authorized permissioned by a central authority should be considered a blockchain.
These blockchains serve as a distributed version of multiversion concurrency control MVCC in databases. An advantage to an open, permissionless, or public, blockchain network is that guarding against bad actors is not required and no access control is needed. Bitcoin and other cryptocurrencies currently secure their blockchain by requiring new entries to include a proof of work. To prolong the blockchain, bitcoin uses Hashcash puzzles.
In , venture capital investment for blockchain-related projects was weakening in the USA but increasing in China. As of April [update] , bitcoin has the highest market capitalization. Permissioned blockchains use an access control layer to govern who has access to the network. They do not rely on anonymous nodes to validate transactions nor do they benefit from the network effect. Nikolai Hampton pointed out in Computerworld that "There is also no need for a '51 percent' attack on a private blockchain, as the private blockchain most likely already controls percent of all block creation resources.
If you could attack or damage the blockchain creation tools on a private corporate server, you could effectively control percent of their network and alter transactions however you wished.
It's unlikely that any private blockchain will try to protect records using gigawatts of computing power — it's time consuming and expensive. This means that many in-house blockchain solutions will be nothing more than cumbersome databases. The analysis of public blockchains has become increasingly important with the popularity of bitcoin , Ethereum , litecoin and other cryptocurrencies. The process of understanding and accessing the flow of crypto has been an issue for many cryptocurrencies, crypto-exchanges and banks.
This is changing and now specialised tech-companies provide blockchain tracking services, making crypto exchanges, law-enforcement and banks more aware of what is happening with crypto funds and fiat crypto exchanges. The development, some argue, has led criminals to prioritise use of new cryptos such as Monero. It is a key debate in cryptocurrency and ultimately in blockchain. In April , Standards Australia submitted a proposal to the International Organization for Standardization to consider developing standards to support blockchain technology.
Many other national standards bodies and open standards bodies are also working on blockchain standards. Blockchain technology can be integrated into multiple areas. The primary use of blockchains is as a distributed ledger for cryptocurrencies such as bitcoin ; there were also a few other operational products which had matured from proof of concept by late Individual use of blockchain technology has also greatly increased since According to statistics in , there were more than 40 million blockchain wallets in in comparison to around 10 million blockchain wallets in Most cryptocurrencies use blockchain technology to record transactions.
For example, the bitcoin network and Ethereum network are both based on blockchain. On 8 May Facebook confirmed that it would open a new blockchain group  which would be headed by David Marcus , who previously was in charge of Messenger. Facebook's planned cryptocurrency platform, Libra now known as Diem , was formally announced on June 18, The criminal enterprise Silk Road , which operated on Tor , utilized cryptocurrency for payments, some of which the US federal government has seized through research on the blockchain and forfeiture.
Governments have mixed policies on the legality of their citizens or banks owning cryptocurrencies. China implements blockchain technology in several industries including a national digital currency which launched in Blockchain-based smart contracts are proposed contracts that can be partially or fully executed or enforced without human interaction.
A key feature of smart contracts is that they do not need a trusted third party such as a trustee to act as an intermediary between contracting entities -the blockchain network executes the contract on its own. This may reduce friction between entities when transferring value and could subsequently open the door to a higher level of transaction automation. But "no viable smart contract systems have yet emerged.
