CryptoCoin ($CRC) — The Future of Decentralized Finance

About

A full-stack cryptocurrency, reborn on EVM.

CryptoCoin is a technical reference implementation of a complete cryptocurrency stack — a peer-to-peer node, an HD wallet CLI, a block explorer served over REST, on-chain smart contracts, Merkle-tree state commitments, proof-of-work consensus over keccak digests, and JSON-RPC transport for third-party tooling. Everything the classical cryptocurrency stack needs, bundled into one inspectable system.

This is the on-EVM edition. CRC lives as an ERC20 on Robinhood Chain, hard-capped at 21,000,000, mineable by anyone with a laptop, and armored against chart-rug behavior by a per-wallet cooldown.

Tokenomics

Immutable. Scarce. Fair.

21,000,000

Hard cap

Bitcoin-lineage supply. No inflation, no admin key, no upgrade path.

5,000,000

Premine

Sent to the deployer for initial liquidity provisioning. Everything else is mined.

16,000,000

Mineable pool

Distributed via proof-of-work over the network's lifetime.

50 CRC
Per solve
Flat reward. No halving. No lottery. One valid nonce = 50 CRC.

5 min

Per-wallet cooldown

Rate limit that holds regardless of hashrate — a whale with 100 GPUs earns the same per wallet as anyone else.

60 sec

Target rhythm

Difficulty retargets every 128 solves toward one solve per 60 seconds.

Architecture

Every primitive that makes a chain a chain.

CryptoCoin bundles the full crypto-native stack into a single inspectable system. Each layer is exposed on its own port, over its own transport, so tooling in every language can hook in.

⚙

Node

Single process running P2P networking, mempool, blockchain state, PoW consensus, miner, and the smart-contract VM.

🔑

Wallet / CLI

ECDSA over secp256k1. Hierarchical-deterministic key derivation. Base58Check addresses. Offline transaction signing.

🔍

Block Explorer

REST API over indexed blocks, transactions, accounts, receipts — plus a lightweight web UI for browsing chain history.

⛏

Proof-of-Work

keccak256 digest over challenge ‖ minerAddress ‖ nonce. Bitcoin-style epoch retargeting every 128 solves.

📜

Smart Contracts

Deterministic on-chain execution with structured event logging and indexed topics for high-signal listeners.

🌳

Merkle Trees

Block-level state commitments. Light clients verify inclusion without running a full node.

🔌

JSON-RPC

Port 8332. Canonical transport for wallets and third-party integrations.

🌐

REST APIs

Port 8080. Explorer surface: /api/blocks, /api/tx/{id}, plus tokens, addresses and receipts.

📊

Structured Logging

Per-node structured logs. Auditable, greppable, indexable.
