Tick a check only after the terminal agrees.

Eight checks, in order. The command changes with the OS. The expected result does not. Passing marks stay in this browser.

From versions to a root hash

01Node is 20 or newernode -v prints v20, v22, or newer.
02Git answersA version line. On Windows, a new terminal after winget.
03Foundry’s cast answerscast --version prints a version. If the shell cannot find it, reopen the terminal so ~/.foundry/bin is on PATH.
04The RPC is GalileoExactly 16602. Mainnet, if you meant mainnet, is 16661 on https://evmrpc.0g.ai.
05Blocks are movingThe second block number is greater than the first.
06Faucet 0G arrivedThe ether balance is greater than zero, and the faucet transfer is on the Galileo explorer.
07The compute CLI is installedHelp text that mentions setup-network. This does not prove you have credit.
08A storage round-trip returned a root hashupload prints a root hash, hello.txt matches the payload, and Storage Scan on Galileo finds the hash.

A missing binary is the toolchain guide. Do not skip ahead to the RPC.
A chain id other than 16602 is the wrong URL, or a proxy. It is not a rounding error.
A zero balance is the faucet, the address, or a retired testnet. Compare the explorer.
A storage error after a healthy balance is usually the indexer. Galileo uploads in the guide use the turbo indexer.
