Elixir implementation of Ethereum's Blockchain. This includes functionality to build and verify a chain of Ethereum blocks that may be advertised from any peer. We complete the resultant state of the blocktree and form a canonical blockchain based on difficulty.
Exthereum's blocks are specified in a variety of sections throughout the yellow paper, but it's best to start looking under Section 4.4.
export "CFLAGS=-I/usr/local/include -L/usr/local/lib"
cd deps/libsecp256k1 && rebar compile
mix compile
If available in Hex, the package can be installed
by adding blockchain
to your list of dependencies in mix.exs
:
def deps do
[{:blockchain, "~> 0.1.6"}]
end
Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/blockchain.
To debug a given run of the blockchain, you can set breakpoints on contract addresses by setting the BREAKPOINT
environment variable and specifying a contract address to break on. E.g.
BREAKPOINT=bc1ffc1620da1468624a596cb841d35e6b2f1fb6 iex -S mix
...
00:04:18.739 [warn] Debugger has been enabled. Set breakpoint #1 on contract address 0xbc1ffc1620da1468624a596cb841d35e6b2f1fb6.
