What the certificate validates

The certificate states that you passed every graded quiz in the camp. Those quizzes cover the following skills:

• Blockchain fundamentals

  Blocks, hashes, ledgers and why decentralised state is tamper-evident.

• Keys, addresses and wallet safety

  Seed phrases, derivation, custody models and phishing-resistant habits.

• Transactions, nonces and gas

  Fee markets across EVM (gwei), Solana (lamports) and Bitcoin (sats/vByte).

• Consensus and finality

  Proof of Work vs Proof of Stake, reorgs and confirmation depth.

• Smart contracts and tokens

  ABIs, EVM bytecode, ERC-20/721 and Solana programs and accounts.

• Testnet deployment and testing

  Hardhat and Foundry workflows, faucets and deploying a staking contract to Base Sepolia.
