NEAR is a public blockchain platform that uses a proof-of-stake consensus mechanism and provides smart-contract functionality. Its native cryptocurrency is NEAR. It was founded in 2018 by Illia Polosukhin and Alexander Skidanov, with mainnet launching in 2020.

NEAR was designed with a sharded architecture for decentralized applications and high-throughput transactions, intended to serve as an alternative to Ethereum and other layer-one blockchain networks.

NEAR Protocol was founded in early 2017 by Illia Polosukhin and Alexander Skidanov. Initially, the project was established as Near.ai, an artificial intelligence startup focused on program synthesis. Polosukhin was a former engineering manager at Google Research, where he co-authored the 2017 paper "Attention Is All You Need," which introduced the transformer architecture. Skidanov was previously the director of engineering at MemSQL and a software engineer at Microsoft.

The project began development on its sharded architecture in late 2018. In July 2019, NEAR raised $12.1 million in a funding round led by Metastable Capital and Accomplice.

The NEAR mainnet launched in April 2020, initially operating in a "restricted" proof of authority mode to ensure stability. In May 2020, the project closed a $21.6 million funding round led by Andreessen Horowitz.

In 2022, Skyward Finance, an IDO/launchpad built on NEAR blockchain, was exploited for roughly $3 million after an attacker abused a flaw in the project’s treasury redemption contract. The bug, identified by security firm BlockSec, failed to check for duplicate token account IDs, enabling the attacker to redeem wrapped NEAR in a loop within a single transaction. Skyward acknowledged that its treasury had been drained and advised users to cease interacting with the contracts, noting that the incident rendered the SKYWARD token effectively worthless.

In 2023, a blockchain analyst questioned validator decentralization on Avalanche, Solana, NEAR, and other blockchain platforms. A Messari study found that roughly 35% of NEAR’s staked tokens were hosted on Amazon Web Services, yielding a hosting “operational Nakamoto coefficient” of 1 (i.e., more than one-third of stake concentrated on a single provider).

The report also observed geographic concentration of validators and stake in the United States and Germany, limited presence in underrepresented regions, and reliance on a single validator client at the time; taken together, NEAR’s aggregated operational Nakamoto coefficient was estimated at ~1.3, indicating elevated susceptibility to correlated infrastructure or jurisdictional failures relative to a more distributed network.
