Scalable Distributed Key Generation for Blockchains https://eprint.iacr.org/2026/072
Kate et al. proposed the first discrete-log-based DKG protocol tailored for blockchains in their paper, leveraging on-chain consensus for improved performance, supporting asynchronous networks and up to 1/2 Byzantine faults. Kate等人在论文中提出了首个基于离散对数的区块链专用DKG协议，利用链上共识机制提升性能，支持异步网络和高达1/2的拜占庭容错。
Notes
- Existing DKG protocols underutilize blockchain, leaving room for performance improvement.
- New protocol tailored for blockchain, leveraging built-in consensus for efficient DKG.
- Supports asynchronous networks with up to 1/2 Byzantine fault tolerance.
- Uses random beacon for small committees, reducing communication and computation complexity.
- Experiments show faster termination than state-of-the-art protocols with high CPU utilization.
- Completes in ~6.5 seconds in optimistic case for 256-node systems, suitable for large-scale use.
