Agora

Agora is a distributed computing protocol powered by blockchain technology.

repository structure

• core_protocol: core protocol implementation.

  • core: node/peer implementation handling network communication and consensus mechanisms.
  • database: key-value database used to manage the blockchain state.
  • virtual_machine: virtual machine for executing smart contracts.

• explorer: a simple node explorer webpage, written using the Flask framework, for visualizing network activity.

• agora_lang_compiler: compiler implementation for the Agora smart contract language.

  • lexer: performs lexical analysis to convert source code into tokens.
  • parser: builds abstract syntax tree from tokens.
  • ast: defines the abstract syntax tree structure.
  • code_gen: generates executable code for the virtual machine.

• vm_debugger: interactive debugger for the virtual machine.

  • Step-by-step execution of bytecode
  • Stack, memory, and storage inspection
  • Breakpoint support
  • Program state visualization

• docs: documentation and notes about the project.

TODO

Lang Compiler

• Function dispatcher (ABI)
  • Read payload data
  • COPY instruction
  • payload arguments
  • Mappings (storage read/write)

Smart Contracts

• Persistent storage
• Add bloom filter to track events

Node

• Optimizations and fixes
  • Optimize block broadcasting (remove cyclical requests)
  • Implement singleton secp256k1 context

Main Goal

• Compile and deploy a simple token contract on the network
  • Source code: simple_token.agora
