A blockchain[1] [2] [3] originally block chain[4] [5] is a continuously growing list of recordscalled blockswhich are linked and secured using cryptography. It is "an bitcoin wiki lt, distributed ledger that can record transactions between two parties bitcoin wiki lt and in a verifiable and permanent way".
Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority. Blockchains are secure by design and exemplify a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a blockchain. Blockchain was invented by Satoshi Nakamoto in for bitcoin wiki lt in the cryptocurrency bitcoinas its public transaction ledger.
The bitcoin design has been the inspiration for other applications. The first work on a cryptographically secured chain of blocks was described in by Stuart Haber and W. The first blockchain was conceptualized by a person or group of people known as Satoshi Nakamoto in It was implemented the following year by Nakamoto as a core component of the cryptocurrency bitcoinwhere it serves as the public ledger for all transactions on the network.
The words block bitcoin wiki lt chain were used separately in Satoshi Nakamoto's original paper, but were eventually popularized as a single word, blockchain, by The term blockchain 2. Second-generation blockchain technology makes it possible to store an individual's bitcoin wiki lt digital ID and persona" and provides an avenue to help solve the problem of social inequality by "potentially changing the way wealth is distributed". Inthe central securities depository of the Russian Federation NSD announced a pilot project, based on the Nxt blockchain 2.
A blockchain bitcoin wiki lt a decentralized, distributed and public digital ledger that is used to record transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the collusion of the network. They are authenticated by mass collaboration powered by collective self-interests. The use of a bitcoin wiki lt 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. Blockchains have been described as a value -exchange protocol.
Blocks hold batches of valid transactions that are hashed and encoded into a Merkle tree. The linked blocks form a chain. Sometimes bitcoin wiki lt blocks can be produced concurrently, creating a temporary fork.
In addition to a bitcoin wiki lt hash-based history, any blockchain has a specified algorithm for scoring different versions of the history so that one with a higher value can be selected over others. Bitcoin wiki lt 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. Because blockchains are typically built to add the score of new blocks onto old blocks bitcoin wiki lt because there bitcoin wiki lt incentives to work only on extending with new blocks rather than overwriting old blocks, the probability of an entry becoming superseded goes down exponentially [34] as more blocks are built on top of it, eventually becoming very low.
There bitcoin wiki lt 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. In cryptocurrencythis is practically when the money transaction takes place, so a shorter block time means faster transactions.
The block time for Ethereum is set to between 14 and 15 bitcoin wiki lt, while for bitcoin it is 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 bitcoin wiki lt software.
If one group of nodes continues to use the old software while the other nodes use the new software, a split can occur. For example, Ethereum bitcoin wiki lt hard-forked to "make whole" the investors in The DAOwhich had been hacked by exploiting a vulnerability in its code.
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 bitcoin wiki lt 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, bitcoin wiki lt 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 bitcoin wiki lt failure.
Bitcoin wiki lt 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. While centralized data is more easily controlled, information and data manipulation are possible.
By decentralizing data on an accessible ledger, public blockchains make block-level data transparent to everyone involved. Every node in a decentralized system has bitcoin wiki lt copy of the blockchain. Data quality is maintained by massive database replication [9] 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, [33] 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. The great 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. Financial companies have not prioritised decentralized blockchains.
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 bitcoin wiki lt the network effect. The New York Times noted in both and that many corporations are using blockchain networks "with private blockchains, independent of the public system. Nikolai Hampton pointed out in Computerworld that "There is also no bitcoin wiki lt 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.
Data interchange between participants in a blockchain is a technical challenge that could inhibit blockchain's adoption and use. This has not yet become bitcoin wiki lt issue because thus far participants in a blockchain have agreed either tacitly or actively on metadata standards. Standardized metadata will be the best approach for permissioned blockchains such as payments and securities trading with high bitcoin wiki lt volumes and a limited number of participants. Such standards reduce the transaction overhead for the blockchain without imposing burdensome mapping and translation requirements on the participants.
However, Robert Kugel of Ventana Research points out that general purpose commercial blockchains require a system of self-describing data to permit automated data interchange. According to Kugel, by enabling universal data interchange, self-describing data can greatly expand the number of participants in permissioned commercial bitcoin wiki lt without having to concentrate control of these blockchains to a limited number of behemoths.
Self-describing data also facilitates the integration bitcoin wiki lt data between disparate blockchains. Blockchain technology can be integrated into multiple areas. The primary use of blockchains today is as a distributed ledger for bitcoin wiki ltmost notably bitcoin. Blockchain technology has a bitcoin wiki lt potential to transform business operating models in the long term.
Blockchain distributed ledger technology is more a foundational technology —with the potential to create new foundations for global economic and social systems—than a disruptive technologywhich typically "attack a traditional business model with a lower-cost solution and overtake incumbent firms quickly".
As of [update]some observers remain bitcoin wiki lt. Steve Wilson, of Constellation Research, believes the technology has been hyped with bitcoin wiki lt claims. This means specific blockchain applications may be a disruptive innovation, because substantially lower-cost solutions can be instantiated, which can disrupt existing business models.
Blockchains alleviate the need for a trust service provider and are predicted to result in less capital being tied bitcoin wiki lt in disputes. Blockchains have the potential to reduce systemic risk and financial fraud. They automate processes that were previously time-consuming and done manually, such as the incorporation of businesses. As a distributed ledger, blockchain reduces bitcoin wiki lt costs involved in verifying transactions, and by removing the need for trusted "third-parties" such as banks to complete transactions, the technology also lowers the cost of networking, therefore allowing several applications.
Starting with a strong focus on financial applications, blockchain technology is extending to activities including decentralized applications and collaborative organizations that eliminate a middleman. Frameworks and trials such as the one bitcoin wiki lt the Sweden Land Registry aim to demonstrate the effectiveness of the blockchain at speeding land sale deals.
The Government of India is fighting land fraud with the help of a blockchain. In Octoberone of the first international property transactions was completed successfully using a blockchain-based smart contract. Each of the Big Four accounting firms is testing blockchain technologies in various formats.
It is important to us that everybody gets on board and prepares themselves for the revolution set to take place in the business world through blockchains, [to] smart contracts and digital currencies. Blockchain-based smart contracts are contracts that can be partially or fully executed or enforced without human interaction. The IMF believes smart contracts based on blockchain technology could reduce moral hazards and optimize the use of contracts in general.
Some blockchain implementations could enable the coding of contracts that bitcoin wiki lt execute when specified conditions are met.
A blockchain smart contract would be enabled by extensible programming instructions that define bitcoin wiki lt execute an agreement. Companies have supposedly been suggesting blockchain-based currency solutions in the following two countries:. Some countries, especially Australia, are providing keynote participation in identifying the various technical issues associated with developing, governing and using blockchains:.
