# Multisig
|
|
|
|
The multisig is represented on chain by the `Multisig` contract.
|
|
|
|
### `vote(keys: Vec<Vec<u8>>)`
|
|
|
|
Lets a validator vote on a set of keys. Once all validators have voted on these
|
|
keys, it becomes the tracked set of keys for incoming funds.
|
|
|
|
The old keys are eligible to still receive transactions for a provided grace
|
|
period. This means nodes are expected to track and oraclize incoming
|
|
transactions for both sets of keys. At the end of the grace period, the old keys
|
|
are dropped from consideration, and all funds are forwarded to the new keys at
|
|
the next transaction interval for a given chain.
|
|
|
|
The old keys are expected to process outbounds until they forward their funds,
|
|
at which point the new keys are expected to process outbounds.
|
|
|
|
Unlike transactions in, which is confirmed as part of the BFT process, a 100%
|
|
vote is used here. While the BFT process would confirm that keys were generated
|
|
and enough nodes acknowledge them the wallet would be spendable from, it does
|
|
not confirm fault tolerance. If the other 33% of nodes failed to receive their
|
|
key shares somehow, the multisig which is intended to be t-of-n would instead be
|
|
t-of-t.
|
|
|
|
Accordingly, validators are allowed to vote multiple times, and the first key
|
|
set to receive the necessary votes becomes the new key set.
