RinCoin Core

RinCoin is a decentralized digital currency, based on Bitcoin Core, that introduces a new Proof-of-Work hashing algorithm called RinHash. RinHash is a hybrid PoW algorithm designed for both security and ASIC-resistance, combining BLAKE3, Argon2d, and SHA3-256. This README provides an overview of RinCoin’s specifications, the RinHash algorithm, and network parameters.

Key Specifications

• Coin Name / Ticker: RinCoin (RIN)
• Consensus Mechanism: Proof-of-Work (PoW) – RinHash algorithm (BLAKE3 → Argon2d → SHA3-256)
• Block Target Time: 1 minute (60 seconds per block)
• Block Reward: 50 RIN (initial coinbase reward per block)
• Halving Schedule: Reward halves every 210,000 blocks (~145 days at 1 min blocks)
• Difficulty Adjustment: Every 2016 blocks (~33.6 hours)
• Proof-of-Work Hash: 256-bit output
• Address Format: Base58 addresses start with R
• Network Ports: P2P: 9555, RPC: 9556
• Network Magic: 0x52 0x49 0x4E 0x43 ("RINC")

Proof-of-Work Algorithm: RinHash

RinHash is a custom proof-of-work algorithm using:

1. BLAKE3: Fast initial hashing
2. Argon2d: Memory-hard step to resist ASICs
3. SHA3-256: Final standard cryptographic hash

A valid block satisfies:
SHA3-256( Argon2d( BLAKE3(block_header) )) < Target

This design provides:

• Fast verification
• Memory-hardness to deter ASICs
• Compatibility with existing 256-bit PoW frameworks

Network and Usage

• Magic bytes: 0x52 0x49 0x4E 0x43
• Ports: 9555 (P2P), 9556 (RPC)
• Mining: CPU/GPU mining supported
• Wallet: Full-node wallet with RIN units

Developer Notes

See chainparams.cpp for network configuration.
