We want to reconstruct bitcoin system, since it has been developped for 10 years.
The project still in developping, we are constructing from zero line of source code, and in first phase we will release a concise system that assume carry out functional verification.
The project is written in python, it supports Python2.7+ or Python3.4+
Setup package not ready yet, please clone the project, and put it to python's library directory in your machine.
Current version only can run in MAC OS.
- Nondeterministic wallet
Create wallet addresss:
from nbc.wallet import *
addr = Address.generate()
print(addr)Get public key:
pubKey = addr.publicKey()Save to file and load from file:
saveTo('default.txt',addr)
addr_ = loadFrom('default.txt')
print(addr_)Save and load by encryption:
saveTo('default2.txt',addr,b'password')
addr2 = loadFrom('default2.txt',b'password') # or: u'密码'.encode('utf-8')
print(addr2)
addr3 = loadFrom('default2.txt') # system will prompt inputing when omit password- Deterministic wallet (HD wallet)
Create wallet addresss:
from nbc.wallet import *
addr = HDWallet.from_master_seed('HDWallet seed')
print(addr)Extend key:
master = HDWallet.from_master_seed('HDWallet seed')
prvMaster = master.to_extended_key(include_prv=True)
pubMaster = master.to_extended_key()
webWallet = HDWallet.from_extended_key(pubMaster)
child2342 = webWallet.child(23).child(42)Save to file and load from file:
saveTo('hd.txt',addr)
saveTo('hd2.txt',addr,b'password')
addr_ = loadFrom('hd.txt')
print(addr_)
addr2 = loadFrom('hd2.txt',b'password')
print(addr2)- Signature and verification for wallet keys
from nbc.wallet import *
addr = Address.generate()
ss = addr.sign(b'example')
addr.verify(b'example',ss)
addr.publicKey().verify(b'example',ss)
addr2 = HDWallet.from_master_seed('HDWallet seed')
ss2 = addr2.sign(b'example')
addr2.verify(b'example',ss2)
