# SEDA Layer One SEDA secures data using heavily battle and time-tested algorithms. The SEDA Chain bases its security on Proof-of-Stake (PoS), using the Cosmos SDK as a foundation. Users may delegate their stake to validators participating in consensus to secure the network. Any entity can run a validator node on SEDA, where the top 100 validators are selected for participation based on their staked weight, as delegated from the community. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
