# 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\<Coin>): 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 t-of-n multisig, where n is the amount
of key shares in the validator set and t is `n / 3 * 2 + 1`, per curve required
by its coins. This multisig is secure to hold funds up to 67% of the validator
set's bond value. If funds exceed that threshold, there's more value in the
multisig than in the supermajority of bond that must be put forth to control it.

### Participation in the BFT process

All validator sets participate in the BFT process. Specifically, a block
containing `Oraclization`s 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, `Oraclization`s 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.
