  2. Blockchain - Wikipedia

    en.wikipedia.org/wiki/Blockchain

    Bitcoin and other cryptocurrencies currently secure their blockchain by requiring new entries to include proof of work. To prolong the blockchain, bitcoin uses Hashcash puzzles. While Hashcash was designed in 1997 by Adam Back , the original idea was first proposed by Cynthia Dwork and Moni Naor and Eli Ponyatovski in their 1992 paper "Pricing ...

  3. Bitcoin protocol - Wikipedia

    en.wikipedia.org/wiki/Bitcoin_protocol

    A diagram of a bitcoin transfer. The bitcoin protocol is the set of rules that govern the functioning of bitcoin.Its key components and principles are: a peer-to-peer decentralized network with no central oversight; the blockchain technology, a public ledger that records all bitcoin transactions; mining and proof of work, the process to create new bitcoins and verify transactions; and ...

  4. Blockchain analysis - Wikipedia

    en.wikipedia.org/wiki/Blockchain_analysis

    Blockchain analysis is the process of inspecting, identifying, clustering, modeling and visually representing data on a cryptographic distributed-ledger known as a blockchain. [ 1 ] [ 2 ] The goal of blockchain analysis is to discover useful information about different actors transacting in cryptocurrency.

  5. Distributed ledger - Wikipedia

    en.wikipedia.org/wiki/Distributed_ledger

    The most common form of distributed ledger technology is the blockchain [citation needed] (commonly associated with the bitcoin cryptocurrency), which can either be on a public or private network. Infrastructure for data management is a common barrier to implementing DLT.

  6. Proof of stake - Wikipedia

    en.wikipedia.org/wiki/Proof_of_stake

    For a blockchain transaction to be recognized, it must be appended to the blockchain. In the proof of stake blockchain, the appending entities are named minters or validators (in the proof of work blockchains this task is carried out by the miners); [2] in most protocols, the validators receive a reward for doing so. [3]

  7. Proof of work - Wikipedia

    en.wikipedia.org/wiki/Proof_of_work

    At the IACR conference Crypto 2022 researchers presented a paper describing Ofelimos, a blockchain protocol with a consensus mechanism based on "proof of useful work" (PoUW). Rather than miners consuming energy in solving complex, but essentially useless, puzzles to validate transactions, Ofelimos achieves consensus while simultaneously ...

  8. Bitcoin - Wikipedia

    en.wikipedia.org/wiki/Bitcoin

    Nodes in the peer-to-peer bitcoin network verify transactions through cryptography and record them in a public distributed ledger, called a blockchain, without central oversight. Consensus between nodes is achieved using a computationally intensive process based on proof of work, called mining, that secures the bitcoin

  9. The Graph - Wikipedia

    en.wikipedia.org/wiki/The_Graph

    The Graph volunteers, known as Curators, Indexers, and Delegators work to process data and share it with Consumers. [1] The Graph offers support to index data from 25 different blockchain protocols including Ethereum , NEAR, Arbitrium, Optimism, Polygon , Avalanche , Celo, Fantom, and Moonbeam.
