NEAR Protocol
NEAR Protocol is a sharded blockchain with smart contracts, human-readable accounts, and a flexible key management system. Its native cryptocurrency is NEAR.

Moreover, and according to an independent source, as of today (Aug 1st, 2025) NEAR is the blockchain with most number of active accounts and is top 4 in number of transactions
History
NEAR was conceived in 2017 by Illia Polosukhin and Alexander Skidanov. Development started in 2018, with the network going live in 2020 as a monolithic chain.[4][2][1]
In 2021 the network started migrating towards a sharded design named Nightshade, authored by Polosukhin and Skidanov.[3]
During 2024 two major network updates were released. The first one introduced stateless validation, allowing to divide the network into independent shards.[5] The second enabled NEAR smart contracts to sign transactions for foreign chains, such as Bitcoin, Ethereum and Solana.[6]
Architecture
NEAR Protocol is a decentralized network, in which a fixed number of nodes validate transactions using a proof-of-stake consensus mechanism, and register them in a blockchain.[3][7]
Validators are grouped into independent shards, each responsible for a portion of the network's state and transactions. Approximately every 600 milliseconds a new block is produced. Approximately every 12 hours (known as an epoch) the network's validators are re-elected and re-assigned one of the existing shards. [7]
Accounts
In order to act within the NEAR network, users must create an account. Accounts are identified through either human-readable name, e.g. alice.near, an alphanumeric string or ethereum-like accounts.
NEAR accounts hold NEAR tokens, but can be created with no balance.
Keys
Each account is associated with zero, one or more public-key cryptography, which are used to sign transactions.
NEAR Protocol distinguishes between two types of keys: Full-access keys, which allow complete control over the account, and function-call keys, which grant limited permissions to calling specific functions on a specific smart contract.
Smart Contracts
All NEAR accounts can host programmable logic known as smart contracts, which are written in high-level languages such as Rust or Python and compiled into WebAssembly. A global registry of smart contracts exists, allowing accounts to share and reuse code across the network.
Smart contracts can interact with each other through asynchronous function calls. They can also yield execution and resume once an external call is received.
Transactions
Transactions allow accounts to perform an action (or series of actions) against a specific target account on the network.
The actions an account can make are limited to: call a function on a contract, create a sub account, deploy a contract on itself, add or remove a key on itself, delete itself. Accounts can also natively delegate the transaction costs to another account through an action known as DelegateAction.
Gas
All transactions incur a fee known as gas, which is paid by the account initiating the transaction. Fees are fixed, and users cannot pay extra gas to prioritize their transactions.
