Constants

const DefaultRequiredApprovalsForSealValidation = 0

DefaultRequiredApprovalsForSealValidation is the default number of approvals that should be present and valid for each chunk. Setting this to 0 will disable counting of chunk approvals this can be used temporarily to ease the migration to new chunk based sealing. TODO:

• This value is for the happy path (requires just one approval per chunk).
• Full protocol should be +2/3 of all currently staked verifiers.
