Program Ape Friends can do their own compilation to build the installation package, there are problems can be directly Dabigatran discussion 161928517 (annotated: CSDN), also welcome the program ape Friend Pullrequest to me, only knowledge sharing can promote the prosperity of Bitcoin.

can support any algorithm (Sha256,scrypt,x11,x13,nist,grostel, and the concatenation of these algorithms) and parameter customization.

There are currently pre-built bitcoin SHA256 and the scypt of the Wright coins, as well as sha3-256 (Keccak).

Online compilation currently offers three types of installation packages:

1,linux/unix Daemon Program (with wallet function)

2,MAC Wallet Installation Package

3,windows Wallet Installation Package

2, the change of the cottage currency steps: (1) Move out of the latest Bitcoin source code

Bitcoin Official code: Https://github.com/bitcoin/bitcoin

Fake currency code address (immediately following bitcoin update): Https://github.com/imharrywu/fastcoin

git clone https://github.com/imharrywu/fastcoin

The changes are all snippets of code, please use Eclipse to open the evicted code and view it in comparison.

(2) Modifying the Genesis block
