This release adds a new network option
--network 193, which is the new public testnet that implements VIP-193. The VIP is the part of PoA2.0 consensus upgrade and proposes:
- VRF-based source of randomness that improves the security of the current leader selection mechanism, making it immune to attacks like corruption attacks or grinding attacks.
- Committee-endorsing block producing process that reduces the probability of forking, resulting in the decreased confirmation delay and increased throughput (TPS).
