What This Covers

Blockchain fundamentals and practical interaction — the technology, not the speculation. In scope: Distributed ledgers, consensus, transactions, smart contract interaction, wallets, token standards. Out of scope: Trading strategies, price analysis, specific DeFi protocols, Solidity development (see dedicated skills).

Core Concepts

ConceptOne-linerDistributed ledgerShared database synchronized across nodes, no single ownerConsensusHow strangers agree on truth without trusting each otherImmutabilityChanging history requires re-doing all subsequent workSmart contractCode that executes automatically when conditions are metGasFee paid to network for computation For mental models and analogies, see concepts.md.

Developer Quick Reference

// Read contract (viem) const balance = await client.readContract({ address: TOKEN, abi: erc20Abi, functionName: 'balanceOf', args: [wallet] }) // Write requires wallet + confirmation wait const hash = await walletClient.writeContract({...}) const receipt = await client.waitForTransactionReceipt({ hash }) Common traps: missing allowance checks, wrong decimals (ETH=18, USDC=6), not awaiting confirmations. For full patterns, see dev.md.

When to Use Blockchain

✅ Use when: Multiple parties need shared truth, no trusted authority exists, immutability is critical, settlement costs are high. ❌ Don't use when: Single org controls data, you trust a central authority, data needs deletion (GDPR), or a database solves it. The Database Test: Would PostgreSQL with audit logs solve this? If yes, skip blockchain. For decision framework and enterprise platforms, see evaluation.md.

Security Essentials

Seed phrase = master key — never share, never screenshot Hardware wallet > software wallet > exchange Test transactions before large transfers Verify URLs obsessively — phishing clones are sophisticated For wallet security and scam patterns, see security.md.

Category context

Agent frameworks, memory systems, reasoning layers, and model-native orchestration.
