Chain Relay Network (CRLN) is a decentralized marketplace that connects dApp developers and infrastructure providers through its trustless API protocol. This ensures secure connections and rewards for node providers. The network operates a two-sided marketplace portal that uses its native cryptocurrency, CRLN, to facilitate transactions. Developers stake a fixed amount of CRLN to guarantee a specific number of relays per session, while node providers stake CRLN on a per-node basis and receive CRLN rewards for servicing relays. By purchasing CRLN upfront, users can eliminate recurring payments to traditional infrastructure providers. If the service is no longer needed, users can sell their staked CRLN to another user. Node providers receive dynamic and proportional CRLN rewards based on the number of relays and transaction fees in each block.
