What is a Core RPC Node?

Access Bitcoin-secured smart contracts

A Core RPC node provides applications with access to the first blockchain combining Bitcoin's security with EVM programmability. Core's Satoshi Plus consensus uniquely leverages Bitcoin miners and stakers to secure an EVM-compatible smart contract platform, creating a bridge between Bitcoin's $1.3T ecosystem and DeFi innovation.

Why Core is revolutionary

Core solves a fundamental challenge: Bitcoin is the most secure blockchain but lacks smart contracts, while EVM chains have programmability but less security. Satoshi Plus consensus allows Bitcoin miners to simultaneously secure Core while mining Bitcoin, bringing Bitcoin-level security to smart contracts without compromising either network.

Core advantages:

  • Bitcoin security — 65%+ of Bitcoin hash power securing Core
  • Satoshi Plus — innovative PoW + DPoS hybrid consensus
  • Non-custodial BTC staking — stake Bitcoin without bridges
  • EVM compatible — full Solidity and Ethereum tooling
  • Bitcoin alignment — designed to complement Bitcoin ecosystem
  • Proven technology — 300M+ transactions processed

Satoshi Plus consensus explained

Satoshi Plus combines three security sources: (1) Bitcoin miners delegating hash power, (2) Bitcoin holders staking BTC non-custodially, and (3) CORE token stakers. This triple security model creates unprecedented decentralization and resistance to attacks.

How Satoshi Plus works:

  1. Bitcoin miners write Core validator addresses in Bitcoin blocks
  2. Bitcoin holders stake BTC to Core validators (non-custodial)
  3. CORE token holders delegate to validators
  4. Validators selected based on combined hash power, BTC, and CORE
  5. Block rewards distributed to miners, stakers, and validators

Non-custodial Bitcoin staking

Core enables Bitcoin holders to stake their BTC to earn yield without moving Bitcoin off the Bitcoin network. This non-custodial mechanism uses Bitcoin's native multisig and timelocks, ensuring Bitcoin never leaves the Bitcoin blockchain — a revolutionary approach to Bitcoin DeFi.

This design makes Core the most Bitcoin-native smart contract platform, fundamentally aligned with Bitcoin's security model and ethos.

Technical Documentation

Quick start for developers

Supported RPC Methods

Core supports all standard Ethereum JSON-RPC methods:

  • eth_blockNumber — current block number
  • eth_getBalance — CORE token balance
  • eth_call — execute view functions
  • eth_sendRawTransaction — broadcast transactions
  • eth_getTransactionReceipt — transaction confirmation
  • eth_getLogs — event logs and filters
  • eth_gasPrice — current gas price
  • eth_estimateGas — gas estimation
  • eth_subscribe — WebSocket subscriptions

Code Examples

💻

JavaScript (ethers.js) — Core Connection:

const { ethers } = require('ethers');

const provider = new ethers.JsonRpcProvider('https://rpc.crypto-chief.com/core/YOUR_API_KEY');

// Verify we're on Core
const network = await provider.getNetwork();
console.log('Chain ID:', network.chainId); // 1116

// Get CORE balance
const balance = await provider.getBalance('0x...');
console.log('CORE Balance:', ethers.formatEther(balance));

// Interact with coreBTC (wrapped Bitcoin on Core)
const COREBTC = '0x...';
const btcABI = ['function balanceOf(address) view returns (uint256)'];
const coreBTC = new ethers.Contract(COREBTC, btcABI, provider);

const btcBalance = await coreBTC.balanceOf('0x...');
console.log('coreBTC:', ethers.formatUnits(btcBalance, 8));
💻

Python (web3.py) — Core Setup:

from web3 import Web3

w3 = Web3(Web3.HTTPProvider('https://rpc.crypto-chief.com/core/YOUR_API_KEY'))

print('Connected to Core:', w3.is_connected())
print('Chain ID:', w3.eth.chain_id)  # 1116
print('Latest block:', w3.eth.block_number)
print('Gas price:', w3.eth.gas_price, 'wei')

# Get CORE balance
balance = w3.eth.get_balance('0x...')
print(f'CORE: {balance / 1e18}')
💻

WebSocket — Monitor Core Network:

const { ethers } = require('ethers');
const provider = new ethers.WebSocketProvider('wss://rpc.crypto-chief.com/core/ws/YOUR_API_KEY');

// Monitor new blocks
provider.on('block', async (blockNumber) => {
  const block = await provider.getBlock(blockNumber);
  console.log(`Core block ${blockNumber}: ${block.transactions.length} txs`);
});

// Monitor BTC staking events
const STAKING_CONTRACT = '0x...';
const filter = {
  address: STAKING_CONTRACT,
  topics: [ethers.id('BTCStaked(address,uint256,address)')]
};

provider.on(filter, (log) => {
  console.log('Bitcoin staked on Core:', log);
});
