Checkpoint ACK and NO-ACK States

Understand acknowledgement states after checkpoint submission and how they affect operational monitoring.

Practical outcomes

  • Interpret ACK signals
  • Investigate NO-ACK events
  • Escalate with evidence

How this works in practice

Understand acknowledgement states after checkpoint submission and how they affect operational monitoring.

A Ramestta protocol flow should be explained as a sequence: a wallet or application submits an EVM transaction, Bor executes it, the validator and Heimdall layers coordinate network state, and checkpoints provide a verifiable path toward Polygon and Ethereum-aligned settlement.

Implementation sequence

Turn the topic into a controlled implementation rather than a one-off transaction. Each step below should leave evidence a teammate, user or auditor can independently review.

  1. 01. Interpret ACK signals. Define the expected result, capture the relevant onchain or operational evidence, and stop for review if the result differs from the plan.
  2. 02. Investigate NO-ACK events. Define the expected result, capture the relevant onchain or operational evidence, and stop for review if the result differs from the plan.
  3. 03. Escalate with evidence. Define the expected result, capture the relevant onchain or operational evidence, and stop for review if the result differs from the plan.

Evidence to retain

Useful evidence includes the transaction hash, block number, validator or checkpoint status, and the corresponding RamaScan record. Do not treat a UI success state as the only confirmation for a high-value action.

Control point

Fast execution feedback and deeper settlement are different confirmation stages. Product teams should state which stage their users are seeing and choose confirmation rules appropriate to the value at risk.
