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.\n\nExthereum's blocks are specified in a variety of sections throughout [the yellow paper](http://yellowpaper.io/), but it's best to start looking under Section 4.4.\n\n## Installation\n\n```bash\nmix deps.get\nmix compile\n```\n\nIf [available in Hex](https://hex.pm/docs/publish), the package can be installed\nby adding `blockchain` to your list of dependencies in `mix.exs`:\n\n```elixir\ndef deps do\n  [{:blockchain, \"~\u003e 0.1.6\"}]\nend\n```\n\nDocumentation can be generated with [ExDoc](https://github.com/elixir-lang/ex_doc)\nand published on [HexDocs](https://hexdocs.pm). Once published, the docs can\nbe found at [https://hexdocs.pm/blockchain](https://hexdocs.pm/blockchain).\n\n## Debugging\n\nTo 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.\n\n```bash\nBREAKPOINT=bc1ffc1620da1468624a596cb841d35e6b2f1fb6 iex -S mix\n\n...\n\n00:04:18.739 [warn]  Debugger has been enabled. Set breakpoint #1 on contract address 0xbc1ffc1620da1468624a596cb841d35e6b2f1fb6.\n\n...\n\n-- Breakpoint #1 triggered with conditions contract address 0xbc1ffc1620da1468624a596cb841d35e6b2f1fb6 (start) --\n\ngas: 277888 | pc: 0 | memory: 0 | words: 0 | # stack: 0\n\n----\u003e [ 0] push2\n      [ 1] 0\n      [ 2] 4\n      [ 3] dup1\n      [ 4] push2\n      [ 5] 0\n      [ 6] 14\n      [ 7] push1\n      [ 8] 0\n      [ 9] codecopy\n\nEnter a debug command or type `h` for help.\n\n\u003e\u003e\n```\n\n## Contributing\n\n1.
