NEXA

Nexa is a Layer 1 (L1) Smart Contract Platform and a Proof of Work (PoW) cryptocurrency. It’s uniquely designed for hardware-based scalability, originating from the Bitcoin source code. Nexa functions by using a unique PoW algorithm for a 2-minute block time, enabling new hardware to validate transactions at unmatched speeds. It supports instant transactions, acts as a store of value with Bitcoin-like tokenomics, and offers ultra-scalable smart contract capabilities alongside native tokens without complex standards.

Nexa addresses the critical issues of blockchain scalability, high transaction fees, and slow processing times. It solves these by offering global capacity, capable of over 10 billion transactions daily, enough for the whole planet, thanks to its unique Proof of Work algorithm. Nexa removes bottlenecks related to bandwidth, storage, and computation speed, ensuring no high fees or waiting. Furthermore, its instant transaction capability provides immediate security for certain transactions, with future technology enabling trustless, instant payments for any amount, overcoming common crypto limitations.

Nexa is powered by a unique Proof of Work (PoW) algorithm, engineered for hardware scalability and rapid transaction validation, setting it apart from other UTXO-based blockchains. Originating from the Bitcoin source code, it benefits from a robust and familiar foundation. Key technologies include an ultra-scalable smart contract system that avoids major scaling bottlenecks common in other networks. Additionally, Nexa supports native token functionality directly, eliminating the need for complex ERC-20 standards, while also offering full smart contract power for tokens. This infrastructure is developed by the experienced Bitcoin Unlimited team.

Nexa utilizes parallel UTXO processing where unrelated transactions validate simultaneously, contrasting with Ethereum's sequential execution. Combined with hardware-accelerated nodes and minimized scripting overhead, this enables 40,000+ TPS versus Ethereum's ~30 TPS. Nexa also avoids recurring computation costs by executing smart contracts only during creation rather than validation.

No, Nexa employs Proof-of-Work consensus where mining provides block rewards. There is no staking mechanism, aligning with Bitcoin's security model. Token utility derives from transactional use, smart contract execution, and ecosystem participation rather than staking yields.

Nexa eliminates blind signing risks through deterministic transaction validation before execution. Its UTXO model prevents Miner Extractable Value (MEV) exploitation by validators. Native tokens avoid smart contract vulnerabilities since asset rules enforce at the protocol level. Schnorr signatures provide quantum-resistant cryptography alongside Bitcoin's battle-tested security foundations.

Through atomic secrets – a cryptographic protocol using Diffie-Hellman key exchange. Sellers encrypt NFT content, which remains inaccessible until payment verification. Upon transaction confirmation, buyers derive decryption keys from blockchain data. This enables confidential digital asset transfers without centralized intermediaries while maintaining on-chain settlement finality.

Nexa mirrors Bitcoin's fixed supply (21 trillion NEX) and quadrennial halvings, creating predictable scarcity. Emission decreases from ~2.6 trillion NEX annually pre-halving to 1.3 trillion post-2026 halving. This contrasts inflationary tokens with uncapped supply or perpetual emissions, prioritizing long-term value preservation through programmed scarcity.
