Update methods to return type Hash32 where appropriate

2

### What was wrong? A number of methods return a value from `keccak` which is guaranteed to be 32 bytes. For example, see: https://github.com/ethereum/eth-utils/blob/d05279c6af22b9e7defc0d7a5df0d7d3422e2061/eth_utils/abi.py#L54-L60 Other methods that require the 32-byte...

Import from the curried versions of toolz

2

### What was wrong? `eth_utils.toolz` does not provide access to the curried versions of the methods ### How can it be fixed? Add another `eth_utils.curried.toolz` module like the `eth_utils.toolz` one,...

Clarify solc unavailable message

### What was wrong? The error message is not clear, when solc isn't available. Examples: - https://ethereum.stackexchange.com/questions/26192/errno-2-no-such-file-or-directory-solc-using-py-solc-and-solidity - https://github.com/ethereum/web3.py/issues/467 Proposal: catch and reraise the exception with a note saying something...

[WIP] APIs I expected/wanted on "first contact"

Since this is roughly my first real contact with `lahja`, I wanted to write down my first impressions. I'll leave this open and `[WIP]` for a bit, as I collect...

https://github.com/ethereum/lahja/blob/595a0f52ff825e12ecf244b80dd73e1a88e71d54/lahja/asyncio/endpoint.py#L586-L587 I'm thinking we should run these ^ in a `loop.run_in_executor()` so that long runs don't block lahja's event handling.

Windows support?

### What is wrong? Windows is not supported. Even if we never get trinity supported, just being able to run evm stuff on Windows would be nice. ### How can...

Parse genesis file to create a Chain object

2

### What is wrong? Would be ideal to be able to create a Chain object from a genesis file. This implementation already exists in Trinity, but more reasonably belongs in...

It has a lot of overlap with `create_header_from_parent`, maybe we can drop it altogether to get rid of some duplicate logic.
