Building A Blockchain In .NET Core - Transaction And Reward
In my previous article, I talked about Proof of Work. Proof of Work requires a lot of computing time, in turn, it uses a lot of electricity. One example is that the power consumed by the entire Bitcoin network in November 2017 is higher than that of Ireland. All the nodes in Bitcoin network are volunteers that they “donate” their computing time to the network. The question is why people want to connect their computer to a Blockchain network and use their computing time to help on Proof of Work? The answer is an award.

Building A Blockchain In .NET Core - Proof Of Work

In my previous article, I created a basic blockchain that was used to store transactions. The basic blockchain can be tampered with easily. Even though there was a validation mechanism, by updating a block and re-calculating hashes of all blocks after it, the tampered blockchain passed validation. The situation could become worse in the real world because re-calculation can be done in a short period of time with a modern computer. We must come up with a solution to stop attackers from tampering a blockchain. The solution actually is pretty simple and straightforward. That is Proof of Work.
