aka Data Availability Proofs
‣
- Data availability proofs are a new technology that allows clients to check with very high probability that all the data for a block has been published, by only downloading a very small piece of that block.
- Fraud and data availability proofs are key to enabling on-chain scaling of blockchains (e.g. via sharding or bigger blocks) while maintaining a strong assurance that on-chain data is available and valid. We present, implement, and evaluate a novel fraud and data availability proof system.
