Explain Solana’s validator, Proof of History, consensus, SOL, wallet, and shared-ledger roles, including how cluster-specific Alpenglow migration changes consensus.
On paper, trace a fictional 0.2 SOL payment. Mark the wallet and signing authority, the RPC relay, the selected cluster, the sender and recipient account state, and the evidence n…
Distinguish wallet connection, scoped message login, transaction signing, and submission, and review unsafe requests.
Draw two outcomes after reviewing a fictional wallet request: rejecting closes it without a signature; approving signs only the exact message or transaction bytes presented. Then …
Check a transaction on the correct cluster.
Select Devnet in Solana Explorer and choose a recent public transaction with a visible signature. Run the read-only Devnet inspector for that exact signature. Compare its status a…
Distinguish wallet, mint, and token-account roles, and explain Token-2022 extension design constraints.
Create a balance report with the cluster and context slot, mint address and token program, token-account address, runtime owner program, internal owner, ordinary delegate and allo…
Explain what signing, submitting, confirming, and finalizing mean.
Draw the transaction states prepared → signed → submitted → confirmed → finalized, with failed, expired, and unknown branches. Calculate the example network fee from two signature…
Build a small Solana program from the official starter and explain what a local LiteSVM test proves.
Open the official counter starter. Trace `initialize` from its client test to the program instruction and account state, then trace `increment`. Write down what `anchor build` pro…
Trace a SOL or token transfer and report what the transaction and resulting account state establish.
Write a one-page transfer verification report with one SOL and one token example. For each, record the signature, exact cluster and RPC or explorer source, commitment, execution r…
Explain how native SOL delegation supports stake-weighted consensus, distinguish a stake account's total balance from its effective delegated amount, identify stake-account authorities, and trace activation, deactivation, rewards, and withdrawal without making an investment claim.
Read the fictional records in this lesson and make an evidence table for each: cluster, total account balance, delegated and effective amounts, stake-account state, stake authorit…
