In order to scale the number of validators in the first 6 - 9 months we will investigate improvements to the multisig contract:

Edit, this should also cover:

• Multisig control should allow signer set update by vega token holder vote #1547
• Stranded withdrawal reissuing #1502

Investigate the Gas costs/ amount of gas required for 30, 50… more for validators signing?

• If gas costs increase we may need to consider batching
• What costs per validator on other networks / other comparable actions on Ethereum (benchmark what gas costs seem reasonable)
• Are there any indications of risk that gas costs will go up in the next 6-9 months?

Signature bundles?

• Check rewards spec defines a mechanism about updating validator weights - contracts should be aligned
• What can we do without batching
• What is the least onerous process for the validators or is there some incentive to make the validators do it. Have to assume the weights won’t be updated every epoch? (do we need to write a tool for validators to facilitate this?)
