SharpChain is a simple blockchain implementation for educational purposes, written in C#. It is a simpler, smaller model of the Bitcoin blockchain. I believe it makes it easier to see how the blockchain actually works nicely.

.NET Core 2.0 SDK

If you have Visual Studio, just open the .sln file and build as usual. Alternatively, you can do:

dotnet build

in the folder where the .sln file is.

First you need to get and ID, like so:

localhost:9532/SharpChain/Register

This will return an ID, like 723e83c4-8f43-4e96-a1e2-af895d041a46. After that, SharpChain works exactly like the Bitcoin blockchain. You need to mine blocks with:

localhost:9532/SharpChain/Mine/723e83c4-8f43-4e96-a1e2-af895d041a46

Blocks are needed to store transactions & send coins to someone. You can send coins with:

localhost:9532/SharpChain/SendCoin/723e83c4-8f43-4e96-a1e2-af895d041a46/f6b88148-b0e9-439c-b246-21e7a55e0c11/5

This will send 5 SharpCoins to f6b88148-b0e9-439c-b246-21e7a55e0c11, from 723e83c4-8f43-4e96-a1e2-af895d041a46. The transaction will be added to the next mined block.

You can see your balance anytime with:

localhost:9532/SharpChain/GetBalance/723e83c4-8f43-4e96-a1e2-af895d041a46

If anytime, you want to see the whole chain, you can do:

localhost:9532/SharpChain/GetChain
