Validator node consolidation refers to the trend where a relatively small number of large entities control a significant portion of the validator nodes in a proof-of-stake blockchain network. This can occur due to economies of scale, technical requirements, or capital requirements for staking. It can impact the decentralization and security of the network.
Context
News reports often raise concerns about validator node consolidation as it pertains to the decentralization and censorship resistance of proof-of-stake blockchains. While efficient, a high degree of consolidation could lead to increased central points of failure or influence. Protocols continuously seek ways to promote wider distribution of validator power.
PANDAS uses direct communication and a two-phase seeding/consolidation model to meet the 4-second DAS deadline, ensuring data availability despite malicious nodes.
