Which release/version did you read?

0.12.1 (https://github.com/tendermint/tendermint/releases/tag/v0.12.1)

Why it is a good project to read?

• A full blockchain implementation in Go
• Generic/stand-alone blockchain and consensus engine. Can be used to build custom blockchain applications through the abci interface (also part of the tendermint project).

Starting point

• Tendermint core cli (https://github.com/tendermint/tendermint/blob/v0.12.1/cmd/tendermint/main.go)

Reading order

• Tendermint core cli
• Abci cli
• P2P network
• Transaction, blockchain, consensus

Interesting parts

• Blockchain and consensus
• Abci interface

Any parts should be skipped?

• Non core blockchain stuff.

Any other tips?

• Read the documentation first to learn how the cli works.
• Setup local tendermint core instances. Useful for setting debugger when get stuck.
• Be prepared to invest a lot of time. It's a large project with many dependencies in separate repos. Focus on tendermint core and abci.
