The DFINITY Foundation is a not-for-profit[1] organisation developing the Internet Computer. The Internet Computer is a public blockchain platform which is based on a network of sub-blockchains governed by an ownerless master blockchain. The web3 platform is designed to enhance the Internet with a new form of server-less cloud-functionality. Its internal cryptocurrencyICP is the short form of its underlying protocol, the Internet Computer Protocol.[2]
The Internet Computer was conceived in 2015 by programmer Dominic Williams, the idea being a world computer that cannot be shut down; which originated from the Ethereum ecosystem.[3]
DFINITY was later founded by Williams in October 2016.[4]
In 2018, prominent venture capital firms such as Andreessen Horowitz, Polychain Capital, SV Angel, Wanxiang Blockchain provided financial contributions for less than 10% of the network's governance tokens.[5]
DFINITY raised $61 million from Andreesen Horowitz and Polychain Capital in a February 2018 funding round.[6] A further $102 million funding round in August 2018 brought the project's total funding to $195 million.[7][8][9]
In May 2018, DFINITY distributed around 35 million Swiss francs worth of DFINITY tokens in an airdrop. Due to regulatory concerns, none of the tokens were to be distributed to US residents.[5][10]
Development (2019–2021)
From 2019 to 2021, the Internet Computer was formally developed through several named versions: Copper, Bronze, Tungsten, Sodium, and Mercury.[11]
On 30 June 2020, the Tungsten (or Developer Network) version was announced in an online event.[12][13] and enabled third-party developers to start using the platform to develop web and smartphone apps.[13]
On 30 September 2020, the Sodium version was announced in an online event.[14][15] This version included the Network Nervous System (NNS), the open algorithmic governance system of the Internet Computer.[15]
Post-launch (2021–present)
After successfully launching the Internet Computer protocol in May 2021 accompanied with market cap tumble, the project attracted 500 developers and nearly 250,000 users to its decentralized applications within the first 10 weeks of launch.[16]
Organizational structure of Dfinity
DFINITY was registered as a non-profit foundation in Zug.[17]
The Internet Computer is maintained by many independent data centers and derives its security from a distinctive system of cryptographic signatures[further explanation needed] known as Threshold Relay Consensus.[23] As detailed in the 2018 white paper, the Internet Computer's consensus mechanism consists of the following four layers:[24]
Identities and registry: Active participants are registered with permanent and pseudonymous identities.
Random beacon: Using the BLS digital signature scheme[further explanation needed], registered participants jointly generate a random output, which is unpredictable to anyone until it becomes available to everyone.
Blockchain and fork resolution: Using the random output from the random beacon layer, each participant is ranked deterministically. Proposed blocks are then weighted according to their proposers' ranks (so that blocks from higher-ranked proposers receive higher weight), and forks are resolved by prioritizing the chain with the highest total block weight.
Notarization and finality: Blocks are notarized through threshold signatures created jointly by registered clients. Blocks must be notarized in order to be included in a chain. A transaction is final after two notarizations.
To join the Internet Computer, a data center must obtain a Data Center Identity.[23]
The Internet Computer has a builtin algorithmic governance system known as the Network Nervous System.[23][further explanation needed]
Transactions on the Internet Computer are finalized in 3–5 seconds.[5][25]
