Blockchain Development Tools

Installation

virtualenv blockchain && cd blockchain
git clone https://github.com/chrisbagsrocks/blockchain-dev-tools.git && cd blockchain-dev-tools
./INSTALL.sh
cd ..
source bin/activate
pip install ecdsa

Alternatively, copy all of the *.py files except blockchain_fundamentals.py into the python bin folder, and the blockchain_fundamentals.py file into the python lib folder.

bits.py

Convert bits to and from compact or extended format

You must define "COIN" with two commands, COIN=examplecoin and export COIN

Then you can run:

./bits.py

usage: bits.py [-h] [-c] value

Example

./bits.py -c 0x1e0ffff0 
coming soon

./bits.py 486604799
bits value must be 4 bytes

bs58.py

distribution.py

hash160.py

hash256.py

msgprefixgen.py

Generates pchMessageStart prefixes

You must define "COIN" with two commands, COIN=examplecoin and export COIN

Then you can run:

./msgprefixgen.py

Example

./msgprefixgen.py
Mainnet
pchMessageStart[0] = 0x84;
pchMessageStart[1] = 0xde;
pchMessageStart[2] = 0xab;
pchMessageStart[3] = 0xd5;

Testnet
pchMessageStart[0] = 0xb0;
pchMessageStart[1] = 0xd1;
pchMessageStart[2] = 0xb6;
pchMessageStart[3] = 0xc8;

Regtest
pchMessageStart[0] = 0xcf;
pchMessageStart[1] = 0xbe;
pchMessageStart[2] = 0xc1;
pchMessageStart[3] = 0xab;

pubkey.py

Generate a Private and Public Key

First you need to generate a Private key and use that to generate a Public key. You can use many programs to do this, just make sure you are not using an online generator. That may put your project at risk if they log the private keys. Use something local, you can run the command:

openssl rand -hex 32 

which will output a secure 32-bit private key, which can be used to generate a public key :

with command ./pubkey.py -u YOUR PRIVATE KEY

You must define "COIN" with two commands, COIN=examplecoin and export COIN
