Write a BigchaindB Enhancement Proposal (BEP)

This is the main way to get new BigchainDB code into the project.

There are two general paths:

Create a BEP. Then create a pull request to implement it. And so on.
Create a new pull request straight away. This is less likely to work. It is only going to be permitted if the problem being solved is clear, obvious, small and well-defined in the pull request. If it's not, then a BEP was needed and you need to go back and write a BEP first.

Tips

Review 1/C4, the process we use to accept any new code or PR of any kind, including one that adds a BEP to bigchaindb/BEPs.
Review 2/COSS. Maybe print it for reference. It outlines what can go in a BEP.
Don't spend weeks on your BEP. Version 1 should take a few hours to write up, maximum. You can add to it in the future. The process is iterative. If you need more than a few hours, then consider writing multiple BEPs.
Do not start writing code before you think about it. You should always write a BEP first. Once you do that, you can start implementing it. To do that, make a pull request and say it implements your BEP.
If you're thinking of writing a new issue, think again. See the page Issue Rules.
