# tokucore – A Simple, Powerful Library for Bitcoin Apps.
[](https://travis-ci.org/keyfuse/tokucore) [](https://golangci.com/r/github.com/keyfuse/tokucore) [](https://goreportcard.com/report/github.com/keyfuse/tokucore) [](https://codecov.io/gh/keyfuse/tokucore/branch/master) [](LICENSE) 
## tokucore
*tokucore* is a simple Go (golang) library for creating and manipulating bitcoin data structures like creating keys and addresses (HD/BIP32/BIP39/SegWit) or parsing, creating and signing transactions.
## Overview
* Base58 encoding/decoding
* Block headers, block and transaction parsing
* Transaction creation, signature and verification
* Script parsing and execution
* BIP 32 (deterministic wallets)
* BIP 39 (mnemonic code for generating deterministic keys)
* BIP 173 (Base32 address format for native v0-16 witness outputs)
* Two-Party ECDSA Threshold Signature Scheme (TSS)
* Mult-Party Schnorr Threshold Signature Scheme (TSS)
* Scriptless Adaptor Signature
## Focus
* Simple and easy to use
* No external dependencies
* Full test coverage
## Tests
```
$ export GOPATH=`pwd`
$ go get -u github.com/keyfuse/tokucore/xcore
