Other Definitions

  • Blockchain Technologies 2016 (†789 s.v. "P2P"): Peer-to-peer (P2P) refers to the decentralized interactions that happen between at least two parties in a highly interconnected network. P2P participants deal directly with each other through a single mediation point.


  • Buterin [2017] (†818 s.v. "Conclusion" ): Protocols around decentralized file storage, decentralized computation and decentralized prediction markets, among dozens of other such concepts, have the potential to substantially increase the efficiency of the computational industry, and provide a massive boost to other peer-to-peer protocols by adding for the first time an economic layer. (†2347)
  • Nakamoto 2008 (†804 p.8): To solve this, we proposed a peer-to-peer network using proof-of-work to record a public history of transactions that quickly becomes computationally impractical for an attacker to change if honest nodes control a majority of CPU power. (†2328)
  • Wood 2014 (†803 p.1): In this instance, the token was used to keep peer-to-peer file trading in check, ensuring “consumers” be able to make micro-payments to “suppliers” for their services. (†2335)
