bitcore-lib-crown
This package is under development. It may be unstable, or not work as expected.
What's Different
This package is a variant of bitcore-lib with some differences.
BlockHeader
instance now has a property auxPow
(an AuxPow
instance). AuxPow
inherits MerkleTransaction
, and MerkleTransaction
inherits Transaction
. The same mechanism can be found in Crown Core.
Note that by definition, AuxPow doesn't belong to the block header. BlockHeader
has auxPow
property just for convenience. The AuxPow data doesn't contribute to computing the block hash. The return values of toBuffer
, toObject
and toJSON
method of BlockHeader
also don't include the AuxPow data.
BlockHeader
instance now has a property versionObject
. AuxPow validation needs it. Our block version number is more complex than Bitcoin.
Note that the return values of toBuffer
, toObject
and toJSON
method of MerkleTransaction
and AuxPow
don't include the coinbase link, aux blockchain link or the parent block header. It only includes the parent block coinbase transaction, that is, the first part of the AuxPow data. hash
property and _getHash
method also refers to the hash of this part. So, the AuxPow
class should be treated as just a part of the whole AuxPow. Other parts are in its properties just for convenience.
The return values of toBuffer
, toObject
and toJSON
method of Block
include the whole AuxPow data.
BlockHeader
's validProofOfWork
method now checks AuxPow if it's an AuxPow block, while still using the original way if it's a legacy block (not AuxPow).
