A decentralized blockchain-based network platform.

Inspired by Bitcoin, Ethereum and Solana.

WIP.

crate	description
blockchain	Different utilities to build a blockchain, blocks, hashing, public-private keys, signing...
node	Node implementation in Rust
client	JSON-RPC Client to connect and interact with a node
consensus	Consensus utilities
discovery_server	A signaling server for nodes to find each other
cli	CLI Runner of a Node
explorer	A TUI app to display the evolution of the blockchain and monetary increase of the simulation nodes
metrics_server	A metrics server implementation in Rust

Requirements

• Cargo (nightly toolchain)

Run simulation (WIP)

Run:

cd node
cargo run --example simulation --release

TO-DO

• Reward the block forgers
• Propagate transactions
• Remove transactions from the mempool that has been bundled on a propagated block
• Prioritize sending transactions to the next block forger
• Improve the election algorithm
• Use enum instead of struct to easily have different types of Transactions inside the blocks
• Make the discovery server a library,this way the discovery server could be launched right from the simulation example
• Synchronization support
• Fees ?
• Transactions might be duplicated across different blocks if the network latency is too high, it should make sure the transactions hasn't been already added to a block
• Scalable block size relative to the network performance
• Always have just the X last blocks of the blockchain on memory to avoid infinite memory increase
• Implement a consensus algorithm to prevent bad nodes to ignore certain transactions
• Improve simulation by allowing external nodes to join (this would need to have synchronization support)
• Fix the never-ending memory usage increase
• Discard lost blocks after certain block height to avoid spam.
• A metrics module that sends information such as new blocks or new txs, etc... through a WebSockets connection to an external point such as a server that could display this data in a frontend such as website.
• A website that shows information about a given metric server
• Option to get the current history of a wallet
