vbc

A simple blockchain written in pure V. Very early in its lifecycle. I started writing it because I was learning more about blockchains.

Changelog

0.0.2

• Added in the timestamp to the transactions.
• Changed some test cases (I was wanting to use precomputed hashes but since I added in time to the transactions, I needed to change the test cases to use proof. You can still create a blockchain without a proof parameter "" and it still works)

0.0.1

• Initial project

Specs

• Currently supports a bare blockchain without needed any proof
• Currently supports the ability to require proof to commit to the chain
• Uses MD5, not secure at all but can be switched to any of V's other builtins with a couple lines

FAQ

Why?

• The best way of learning is to build, so building from scratch seemed worth it.

MD5?

• I know its not secure enough for any sort of public blockchain, but I am more interested in using this for logging. Will probably end up using SHA1 later.

What about Coins?

• This is just a blockchain, no coins or tokens, though it has a very simple proof check function.
• Technically you could write a miner and give rewards based on block completion, but that is not my objective.
• This also has no way to distribute the chain or anything like that.

What else?

• I might eventually write a cryptocurrency that uses this chain underneath, but that takes additional time.
