Why PoS DA layers beat data availability committees
Thread102 words
Argues PoS-based DA layers like Celestia and Avail beat DACs on trustlessness, since nodes stake and can be slashed for not serving data, and on fault tolerance, since larger participant sets make data withholding attacks harder.
Key claims
Staked DA nodes can be slashed for failing to provide data
Larger participation sets make withholding attacks harder than with DACs
PoS based DA layers like @CelestiaOrg or @AvailProject have two core benefits over centralized data availability committees (DACs)
✅ Trustlessness
✅ Fault tolerance
1/3
Trustlessness
PoS DA networks use crypto economic incentives to ensure node honesty. Every node that stores data must stake funds in a smart contract, which can can be slashed if they fail to provide data on request, thereby removing trust assumptions that exist with DACs
2/3
Fault tolerance
Proof-of-Stake data availability networks often have higher participation sets than data availability committees. This makes it harder for malicious actors to compromise the group and conduct data withholding attacks
