Golden Age Addresses are split by new, human readable shard prefixes:
“0x00” prefixes are Cyprus1 addresses (Region 0, Zone 0)
“0x01” prefixes are Cyprus2 addresses (Region 0, Zone 1)
“0x10” prefixes are Paxos1 addresses (Region 1, Zone 0)
and so on...
Golden Age Addresses are also split by ledger type (Quai and Qi)
“0x0080” is a Qi address (3rd digit larger than 7)
“0x0060” is a Quai address (3rd digit smaller than 7)
