Validator Sets

Validator Sets are defined at the protocol level, with the following parameters:

  • index (VS): Validator set index, a global key atomically increasing from 0.
  • bond (Amount): Amount of bond per key-share of this validator set.
  • coins (Vec): Coins managed by this validator set.

At launch, there will solely be validator set 0, managing Bitcoin, Ethereum, USDC, DAI, and Monero.

Multisig Management

Every validator set is expected to form a multisig per curve required by its coins. This multisig is secure to hold funds up to 67% of the validator set's bond value.

Participation in the BFT process

All validator sets participate in the BFT process. Specifically, a block containing Oraclizations for a coin must be approved by the BFT majority of the validator set responsible for it, along with the BFT majority of the network by bond.

At this time, Oraclizations for a coin are only expected to be included when a validator from the validator set managing the coin is the producer of the block in question.
