A naïve implementation of Bitcoin Simplified Payment Verification using bloom filters.
This project helped me to gain a better understanding of bitcoin technology.
I struggled a lot to find a complete python library for Bitcoin (if you know one let me know ;)).
In this project a fork of the library python-bitcoinlib is used. I created the fork in order to improve the support to bloom filters and merkle blocks.
- Client to download the Bitcoin block chain (only headers)
- Client to analyze the Bitcoin block chain, using SPV and bloom filters, in order to find your transactions
NOTE: Probably you will have to customize the code used for import the private key if you have exported the key from a wallet different from Bitcoin Core (0.16.0). Please refer at the extensive comment in the file data_store/keys.py.
This is not a Bitcoin wallet! You can use the transactions found to create your own wallet.
