If you want to learn how to build blockchain in Go, this set of posts explains it really well https://jeiwan.cc/posts/building-blockchain-in-go-part-1/

Are there any JavaScript blockchain implementations?

This might sound like a super stupid question but it's the only language I know my way around very well and I'd love to figure out how they work in practice.

Solidity, the etherum language is based on JavaScript

It's actually a lot closer to C than Javascript.

However geth, the Go Ethereum implementation, has a Javascript CLI.

Isn't only the syntax of Solidity based on JS, not the implementation?

How about Truffle? It was recommend by yc blog about blockchain.

Truffle is a framework for writing solidity smart contracts, which themselves run on the ethereum blockchain. Its not a blockchain implementation.

Even though this is a toy blockchain, it is essential to provide a Blockchain.verify() method to check the integrity of the blocks.

Great learning tool. For getting started with blockchains I collect starter scripts in JavaScript, Python, Ruby, etc over at the Awesome Blockchain page [1]. Happy blockchaining! [1] https://github.com/openblockchains/awesome-blockchains
