Blockchain ID Wikipedia

John Light edited this page Oct 29, 2015 · 1 revision

A blockchain ID is a unique identifier that is secured by a blockchain. A user can cryptographically link their blockchain ID to a profile containing arbitrary information e.g. name, biography, website link, public key, social graph, etc. Blockchain IDs are simultaneously secure, human-meaningful, and decentralized, thereby squaring Zooko's triangle.

Uses

Potential uses for blockchain IDs include:

Namecoin

In September 2010 a discussion was started in the Bitcointalk forum about a hypothetical system called BitDNS and generalizing bitcoin, based on a talk at IRC at 14 November 2010. Gavin Andresen and Satoshi Nakamoto joined the discussion in the Bitcointalk forum and supported the idea of BitDNS.[1][2][3] A reward for implementing BitDNS was announced on the Bitcointalk forum in December 2010.[4] Soon a developer decided to implement the BitDNS idea to earn the bounty.[5] On April 18, 2011 Namecoin was introduced by vinced as a multipurpose and distributed naming system based on Bitcoin.[6] WikiLeaks mentioned the Namecoin project via Twitter in June 2011.[7]

Several namespaces were created on Namecoin that let users register blockchain IDs:

  • d/
  • i/
  • u/

In June 2013 the NameID project launched.[8] NameID links blockchain IDs to an OpenID provider so that users can log in to websites that support OpenID without a password. NameID released a Firefox extension called Easy Login which automated the authentication process to make it easier to use.[9]

In March 2014 the company Onename started the u/ namespace and launched a service that let users register a blockchain ID in the u/ namespace.[10] The original name for this system was also “OneName” but has since been generalized, with identifiers registered on the blockchain being referred to as “blockchain IDs.”[11] On September 15, 2015 Onename announced that they were deprecating the u/ namespace and switching their blockchain ID registration service to the Bitcoin blockchain using the Blockstore software.[12][13]

  • .p2p[14]
  • KeyID
  • Account names
    • Subaccounts

Bitcoin

In January 2015 Onename introduced Blockstore, a key-value store built on the Bitcoin blockchain.[15] On September 15, 2015 Onename announced that they were migrating their blockchain ID registration system and the entire u/ namespace on Namecoin over to .id namespace on Bitcoin using Blockstore.[16]

  • id: protocol specifications
    • .id namespace rules

On June 7, 2015 Yanislav Georgiev Malahov announced the BitAlias protocol.[17][18] BitAlias uses OP_RETURN transactions to register aliases which are then associated with a Bitcoin address. A Bitalias is transferable to other Bitcoin addresses.
