I will develop or troubleshoot PoW blockchains, mining pools & wallets

## Blockchain, Mining Pool & Cryptocurrency Wallet Development

Need help creating your own Proof-of-Work blockchain, fixing a mining pool, configuring nodes, or integrating cryptocurrency wallets?

I develop, troubleshoot, and maintain independent blockchain networks and cryptocurrency infrastructure.

### Blockchain Development

• Custom Proof-of-Work blockchain development.
• Bitcoin Core-based cryptocurrency networks.
• SHA-256d mining and consensus configuration.
• Difficulty adjustment algorithms, including ASERT.
• AuxPoW merged mining integration.
• Blockchain nodes, P2P networking, and RPC interfaces.
• Block validation, transaction processing, and network synchronization.
• Blockchain debugging, upgrades, and performance optimization.

### Mining Pools & Infrastructure

• Stratum mining pool development and configuration.
• Native and merged mining support.
• ASIC miner connectivity and troubleshooting.
• PPLNS and solo mining infrastructure.
• Worker statistics, hashrate monitoring, and reporting.
• Block submission and reward accounting.
• Mining pool APIs and external integrations.
• Linux server deployment and monitoring.

### Cryptocurrency Wallets

• Desktop and mobile cryptocurrency wallet development.
• Wallet RPC and blockchain API integrations.
• Transaction creation, signing, and broadcasting.
• Address generation and wallet functionality.
• Blockchain explorers and transaction monitoring.
• Wallet debugging and integration testing.

### Real Project Experience

I created and launched Ruble Core (RUB), an independent Bitcoin Core-based Proof-of-Work blockchain.

The ecosystem includes:

• A functioning SHA-256d blockchain mainnet.
• Native and AuxPoW merged mining.
• A mining pool with Stratum connectivity.
• Desktop and Android cryptocurrency wallets.
• A blockchain explorer.
• Node infrastructure and monitoring systems.
• Integration resources for external mining pools.

### Pricing & Delivery

Starting at 100 USDC for diagnostics and troubleshooting of one specific technical issue.

This includes an initial review of relevant configurations, logs, or code, identification of likely causes, and recommended corrective actions.

Typical delivery: 2 days for a clearly defined diagnostic task.

Implementation, complex bug fixes, custom blockchain development, complete mining pools, and wallet applications are quoted separately based on project requirements.

### Before Ordering

Please describe your blockchain or infrastructure, the issue you want to solve, and the expected result.

I can review technical documentation, relevant code, logs, and configuration details to determine the appropriate solution.

No seed phrases, wallet private keys, or unnecessary server credentials are required.
