How bijoy26/crypto-beacon works
1. Repository purpose
- This is a Truffle-based proof-of-concept for a decentralized community platform called CryptoBeacon.
- The repo is primarily the blockchain application layer: smart contracts, deployment scripts, and local test/development setup. The README also describes a planned front end and IPFS integration, but those pieces are not present in the file tree yet.
2. Core runtime boundary
- The main execution boundary is the Ethereum-compatible network: local Ganache for development and Polygon Mumbai testnet for deployment.
- Users interact with the system through a wallet/Web3 client, which sends transactions to the deployed contract rather than a traditional server backend.
3. Smart contract subsystem
- The contracts/ directory is the on-chain business logic layer.
- Based on the README, the contract likely supports the platform’s core actions: publishing community updates, reading updates, and upvoting posts to establish trust.
- This is the authoritative state store for platform data that must be transparent and tamper-resistant.
4. Deployment pipeline
- The migrations/ folder contains Truffle migration scripts:
- 1_initial_migration.js sets up Truffle’s migration bookkeeping.
- 2_deploy_contracts.js deploys the application contract(s).
- This is the repo’s deployment boundary between source code and a live blockchain network.
5. Local development and testing
- truffle-config.js defines network/compiler settings and is the key configuration file for running against local or remote chains.
- The test/ folder is present but mostly empty, so automated contract testing is only minimally scaffolded in this snapshot.
- The README indicates local development was done with Ganache and Truffle.
6. Frontend / client boundary
- The README describes a front end built with HTML/CSS/Bootstrap/JavaScript and Web3.js, but those source files are not in the tree.
- Architecturally, the intended client would sit outside the blockchain and act as a thin presentation/transaction layer: connect wallet, read contract state, submit updates/upvotes.
7. External storage plan
- The README calls out IPFS as a distributed storage layer to complement blockchain storage.
- The intended architecture is likely: large or user-generated content stored off-chain in IPFS, with only references/hashes and metadata committed on-chain.
- That integration is listed as planned, not yet implemented in this repo snapshot.
8. Network and deployment targets
- The project is designed around Polygon, specifically noted as deployed to Polygon Mumbai Testnet.
- This means the runtime is not a centralized server but a public blockchain network with contract addresses and transaction history visible externally.
9. Assets and documentation
- assets/ contains banners and system architecture imagery used for project presentation, not runtime behavior.
- README.md and changelog.md provide the product narrative and progress status; they are important for understanding intended architecture but do not define executable paths.
10. What is actually implemented vs. planned
- Implemented in this repo: contract code, deployment scripts, Truffle configuration, and the scaffolding for tests.
- Planned but not present: a fully wired Web3 front end, IPFS integration, and production frontend deployment.
- So the current architecture diagram should emphasize a smart-contract-centric dApp foundation with future client and storage layers still pending.
11. Suggested diagram boundaries
- Show three major zones: Client/Wallet, Blockchain (Truffle-deployed Solidity contracts on Polygon/Ganache), and Distributed Storage (IPFS, planned).
- The current repo mostly occupies the middle zone plus deployment tooling; the client and storage zones are architectural targets rather than completed modules.

Components 16
Client boundary
User-facing Web3 presentation and wallet interaction, currently planned rather than implemented in the tree.
- Wallet · User wallet and transaction signer that initiates on-chain actions.
- Web UI · Planned HTML/CSS/Bootstrap/Web3.js presentation layer described in the README.
Blockchain app
Truffle-managed smart contracts and deployment tooling that define the current executable core.
- Contracts · Authoritative on-chain business logic for community updates and trust signals.
contracts - Beacon app · Representative application contract deployed by the migration flow.
contracts - Migrations · Truffle deployment scripts that initialize bookkeeping and deploy the application contract(s).
migrations - Init mig · Sets up Truffle's migration bookkeeping.
migrations/1_initial_migration.js - Deploy app · Deploys the application contract(s) to the target network.
migrations/2_deploy_contracts.js - Truffle cfg · Compiler and network settings for local and remote chain execution.
truffle-config.js - Tests · Minimal contract test scaffold present in the repository.
test
Chain runtime
Ethereum-compatible networks used for local development and deployment targets.
- Ganache · Local Ethereum-compatible development chain used during contract iteration.
- Mumbai · Polygon Mumbai test network used as the public deployment target.
External storage
Planned off-chain storage layer for larger content and references.
- IPFS · Planned distributed storage layer for content too large or suitable for off-chain storage.
Project materials
Documentation and presentation assets that explain the system but do not affect runtime behavior.
- README · Primary narrative for the project goals, architecture, and planned integrations.
README.md - Changelog · Progress and release notes for the project snapshot.
changelog.md - Assets · Banners and architecture imagery used for project presentation.
assets - Package · Dependency and script manifest for the Truffle-based project.
