Chain selection

The parameters of the blockchain are managed by Bitcoin::ChainParams. Switch chain parameters as follows:

Bitcoin.chain_params = :mainnet

This parameter is described in https://github.com/chaintope/bitcoinrb/blob/master/lib/bitcoin/chainparams/mainnet.yml.

Bitcoin.chain_params = :testnet

This parameter is described in https://github.com/chaintope/bitcoinrb/blob/master/lib/bitcoin/chainparams/testnet.yml.

Bitcoin.chain_params = :regtest

This parameter is described in https://github.com/chaintope/bitcoinrb/blob/master/lib/bitcoin/chainparams/regtest.yml.

Bitcoin.chain_params = :signet

This parameter is described in https://github.com/chaintope/bitcoinrb/blob/master/lib/bitcoin/chainparams/signet.yml.

Test

This library can use the libsecp256k1 dynamic library. Therefore, some tests require this library. In a Linux environment, spec/lib/libsecp256k1.so is already located, so there is no need to do anything. If you want to test in another environment, please set the library path in the environment variable TEST_LIBSECP256K1_PATH.

In case the supplied linux spec/lib/libsecp256k1.so is not working (architecture), you might have to compile it yourself. Since if available in the repository, it might not be compiled using the ./configure --enable-module-recovery option. Then TEST_LIBSECP256K1_PATH=/path/to/secp256k1/.libs/libsecp256k1.so rspec can be used.

The libsecp256k1 library currently tested for operation with this library is v0.4.0.
