Crypto 101
Demystify blockchain fundamentals with interactive examples covering cryptographic principles, decentralized ledgers, and consensus mechanisms.
Core Blockchain Principles
Decentralization
Eliminate central authorities using distributed ledger architecture with peer-to-peer network validation models.
// Node synchronization example
const syncNodes = async () => {
return new P2PNetwork({
port: 3000,
initialPeers: ["node1", "node2"]
});
};
Cryptography
Implement secure key generation using ECDSA algorithms with SHA-256 hashing for digital signature verification.
// ECDSA signature generation
const { publicKey, privateKey } = generateKeyPair('ecdsa', {
namedCurve: 'P-256'
});
Consensus
Execute proof-of-stake validation with Byzantine fault tolerance for network synchronization.
// Stake-based validation
const validate = async (validator) => {
return stakeWeight > MINIMUM_STAKE;
};
