The Overlay Network

Powering permissionless and decentralized access to any API.

PreviousOracle ProgramsNextDecentralized Solver Network

Last updated 2 months ago

The Overlay Network is a multi-party computational network built to host tens of thousands of independently operated nodes. The primary responsibility of The Overlay Network is to query data sources as defined by a protocol Oracle Program. By leveraging an Overlay Network SEDA operates a highly decentralized data retrieval system while facilitating increased community participation.

When a data request is issued to the SEDA Network, Overlay Nodes form secret committees. The amount of nodes in a secret committee is determined by the protocol's customized replication factor, configured in their Oracle Program. This secret committee then queries the data sources also specified in an Oracle Program and individually returns data results via a commit reveal scheme. This process maintains data integrity and decentralized data querying, reducing trust of a single source of truth.

Participating in The Overlay Network is designed to be permissionless. Similarly to the operation parameters of main chain nodes, participants may stake SEDA Tokens to Overlay Nodes to perform the operation.

The Overlay Network will launch in phases, with phase one consisting of a whitelisted selection of 20 professional validator companies.
