Godot Blockchain

The idea here is to gain some understanding of how blockchain technology works by building relevant nodes in Godot Engine and coding functionality in GDScript. Then simulate transactions.

Godot coin

This will represent the tokens that get accumulated into stakes that are held.

What is a blockchain?

A blockchain is a growing list of records, called blocks, that are linked using cryptographic hashes. Each block contains a hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree). By design, a blockchain is resistant to modification of its data. This is because once recorded, the data in any given block cannot be altered retroactively without alteration of all subsequent blocks.

Representation of a block

We will use a Proof of Stake (PoS) protocol so as not to waste lots of energy as in a PoW (Proof of Work) system.

• Previous block's hash
• Timestamp - when the block was created
• Transaction data (Merkle tree) - Area of confusion for me!
• Validator address - the validator that was responsible for creating the block

The network

• Blockchain
• Validators - these are servers around the Internet

Validators

• Stake - number of tokens (coins) held
• Address - such as the IP address of the server

Maybe these will somehow handle transactions and when there are enough records, want to create a new block containing the tokens/coins. This is the area that I don't understand yet.

ToDos

• Add test suite
• Figure out how to implement transactions - I don't understand this topic yet
• Understand the role of a Wallet in this system
• Create a UI and graphical representation of nodes
• Be able to run scenarios to simulate activities
