Nexa is a proof-of-work, UTXO Layer-1 blockchain that supports native tokens and smart contracts, aiming to facilitate scalable global peer-to-peer transactions. It is designed for high performance, enabling over 10 billion transactions per day, and supports EVM-like smart contracts as well as the creation and management of Non-Fungible Tokens (NFTs).
Nexa operates on a UTXO (Unspent Transaction Output) model which allows for efficient transaction verification. It employs a proof-of-work consensus mechanism using a unique algorithm that combines elliptic curve multiplication with SHA-256 to ensure network security. Key technologies include the Graphene protocol for block compression, which reduces network traffic, and DS-Proof for instant, confirmation-free transactions. Smart contracts on Nexa are executed using NexScript, enhancing the blockchain's capability to host decentralized applications.
Nexa's scalable and efficient blockchain infrastructure supports a wide array of use cases:
Nexa was developed by the Bitcoin Unlimited team, known for their involvement with Bitcoin Cash. The founding team brings over 70 years of combined experience in the crypto sector. Nexa has focused on scalability and instant transaction capabilities without experiencing any major forks. Its technological evolution includes integrating advanced systems like Graphene and DS-Proof to enable high throughput and smart contract execution while maintaining decentralization.
