BitOasis / CryptoCorp's Multisig python API implementation using the pycoin library.

Currently this requires the p2sh branch of https://github.com/devrandom/pycoin.git.

Examples

export PYCOIN_CACHE_DIR=~/.pycoin_cache
export PYCOIN_SERVICE_PROVIDERS=BLOCKR_IO:BLOCKCHAIN_INFO:BITEASY:BLOCKEXPLORER
digital_oracle --email a@b.com create P:aaa P:bbb
# not recommended - both keys on one machine
digital_oracle --email a@b.com create P:aaa xpub...
digital_oracle -i 0/0/123 address P:aaa xpub...
# shows deposit address
tx -i SOURCE_ADDRESS DESTINATION_ADDRESS/100000 CHANGE_ADDRESS -o tx.bin
digital_oracle sign P:aaa xpub... tx.bin -i 0/0/123
# signs and shows tx hex)
digital_oracle sign P:aaa xpub... tx.bin -i 0/0/123 0/0/124 -c - 0/1/44
# signs tx with two inputs and two outputs. The second output is change.
