Package: digibyte
# Pydigibytetools, Python library for Digibyte signatures and transactions### Advantages:Functions have a simple interface, inputting and outputting in standard formatsNo classesMany functions can be taken out and used individuallySupports binary, hex and base58Transaction deserialization format almost compatible with BitcoinJSElectrum and BIP0032 supportMake and publish a transaction all in a single command line instructionIncludes non-bitcoin-specific conversion and JSON utilities### Disadvantages:Not a full node, has no idea what blocks areRelies on centralized service (blockchain.info) for blockchain operations, although operations do have backups (eligius, blockr.io)### Example usage (best way to learn :) ):> from digibyte import *
