Gigachain

Gigachain is a Layer 1 aimed at heavy computation that argues the metric should shift from transactions per second to instructions per second. The bottleneck it targets is sequential execution: traditional chains make every validator replay the full transaction set, which keeps complex computation off-chain and forces teams to trade away decentralisation and state consistency.

Its mechanism splits transactions into non-conflicting batches by state access, has multiple decentralised executors process them in parallel, generates a SNARK proof per batch and recursively aggregates those into a single block proof, removing redundant re-execution while keeping verifiability. Per its whitepaper, throughput under highly parallel workloads can exceed a sequential model by four orders of magnitude and a multi-threaded in-node design by roughly 500 times, with a target envelope of 61 billion IPS that covers on-chain AI inference, games and financial simulation. The protocol was presented at zkSummit13 in May 2025, the same month its prototype was completed.
