This is my attempt at writing a from-scratch Bitcoin SPV client. The implementation language is C++. This is purely for me to learn about the Bitcoin protocol: you probably shouldn't use this.
If you are interested in learning more about how the Bitcoin protocol works, or are interested in writing you own SPV client, you may find the source code here useful as a reference. I would also recommend taking a look at libbtc, which is more fully featured.
This code is considered alpha and incomplete. To avoid being a nuisance to the network, the client is currently hard-coded to connect to testnet.
Currently the client can connect to the peers via the DNS seed list, and
initiate header sync, downloading the full set of block headers starting from
the genesis block. The block headers themselves are stored in a RocksDB
database, in a directory named .spv.
To build spv, you'll need autoconf, automake, and a bleeding-edge C++17
compiler:
$ ./autogen.sh
$ ./configure
$ makeThe make command will produce an executable at src/spv.
Build dependencies:
- autoconf
- automake
- pkg-config
- libuv (version 1.x)
- librocksdb (version 3.x)
