Steven Barclay d8d8ec3f97 Add PoW version(-list) fields to ProofOfWork & Filter ... Add a numeric version field to the 'ProofOfWork' protobuf object, along with a list of allowed version numbers, 'enabled_pow_versions', to the filter. The versions are taken to be in order of preference from most to least preferred when creating a PoW, with an empty list signifying use of the default algorithm only (that is, version 0: Hashcash). An explicit list is used instead of an upper & lower version bound, in case a new PoW algorithm (or changed algorithm params) turns out to provide worse resistance than an earlier version. (The fields are unused for now, to be enabled in a later commit.)		2021-11-24 15:07:42 +00:00
