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).
