Title: Testnet difficulty and max target Post by: Dusty on April 29, 2012, 08:54:02 PM Hello,
I'm trying to import the testnet block chain on a library I'm working on but speaking of difficulty I'm not understanding well the differences relative to the production network. This is what I've understood until now about prodnet: - max allowed target is 0xFFFF0000000000000000000000000000000000000000000000000000 - corresponding max bits (compressed target) is 0x1D00FFFF While in testnet: - what is the max allowed target? On the wiki it's stated (https://en.bitcoin.it/wiki/Testnet) that "Minimum difficulty of 1.0 on testnet is equal to difficulty of 0.5 on mainnet. This means that the mainnet-equivalent of any testnet difficulty is half the testnet difficulty." so I guess I've to shift left the prodnet max target, getting 0x1FFFE00000000000000000000000000000000000000000000000000000 but I can't find any confirmation for that. - what is the corresponding compressed target? Any help would be greatly appreciated! |
