Main Idea

Nexus is launching its final testnet for an AI-ready 'world supercomputer' L1 blockchain, combining advanced cryptographic techniques and decentralized compute power to handle complex workloads like AI inference.

Key Points

1. Nexus aims to be a 'world supercomputer' by integrating blockchain states into a single succinct proof using a RISC-V-based zkVM for complex workloads, including AI inference.

2. The protocol uses Incrementally Verifiable Computation (IVC) and the Stwo (Circle STARK) prover to aggregate proofs into a Universal Proof, enabling verifiable computation.

3. Nexus has over 2.1 million unique testnet users, with 4,000 active accounts, and employs Sybil detection to ensure legitimacy.

4. The project prioritizes speed over decentralization, focusing on becoming infrastructure for the AI era and fostering user engagement in 'building the future.'

5. Nexus' consensus protocol, inspired by CometBFT and HotStuff-2, ensures fast finality for coordinating globally distributed proving tasks.
