Data Availability (DA)
NODE: DATA-AVAILAB
VERIFICATION: PASSED
01_DEFINITION
Strict Definition
"The guarantee that the data required to reconstruct the state of a blockchain or rollup is available to all network participants."
Liability Check // Risk Analysis
The 'State Lock' risk. If a rollup's DA layer goes offline, you may still 'own' your assets, but you cannot prove it or move them, effectively locking your capital indefinitely.

Strategy Domain
"Select rollups that use highly decentralized DA layers (like Ethereum or Celestia) for mission-critical treasuries."
Operations Standard
"Run a 'Light Node' or 'sampling node' to verify for yourself that your transaction data is indeed available."
Legal & Compliance
"Ensure your DA provider complies with relevant 'Data Persistence' requirements if your industry is highly regulated (e.g., Healthcare, Finance)."
