On decentralized oracles for data availability
This work addresses the need for decentralized systems to verify data availability without trust, potentially enabling new applications in blockchain and distributed computing, though it appears incremental as it builds on existing consensus mechanisms.
The paper tackles the problem of creating a trustless data availability oracle by leveraging Nakamoto consensus, proposing a design that reduces data availability verification to a network construction problem where either most nodes can download a datum or almost none can.
Nakamoto consensus, the protocol underlying Bitcoin, has the potential to secure a new class of systems which agree on non-mathematical truths. As an example of this capability, we propose a design for a trustless, data availability oracle. This exposition reduces the problem of determining whether or not a registered datum is publicly available to the problem of constructing a network in which either almost all nodes can download a given datum, or almost none of them can.
