GO LEARNING PATH · 7 LESSONS

Around Go: blockchain infrastructure

Ethereum, Bitcoin and Cosmos package roles; exact units, RPC, ABI, nonces, key custody and reorg-safe indexing.

  1. Go in blockchain: choose packages by the protocol and the job

    Distinguish RPC applications, transaction tooling and consensus/application frameworks.

  2. Ethereum RPC: verify the chain and bound every operation

    Use an explicit RPC client, operation deadline and expected chain identity.

    3 min · Worked lesson

  3. Token amounts: parse exact base units without float64

    Convert validated decimal text to bounded integer base units with an explicit scale.

  4. Contract ABI: encoding is not permission and eth_call is not a transaction

    Distinguish ABI packing, read simulation, signed transactions and deployment identity.

  5. Nonces, fees and unknown outcomes: one durable owner per account

    Coordinate transaction intent and account nonce allocation before retrying a send.

  6. Signing policy: bind the chain and keep key custody separate

    Validate transaction intent before delegating signing to an explicitly owned key service.

  7. Index events through disconnects and reorgs, not just the happy subscription

    Persist canonical checkpoints and reconcile removed or missing events before final effects.
