Sidecar

Chains can leverage the benefits of Javelin without running on SEQ by running a sidecar. Chains can easily run this sidecar which allows them to opt into having their blocks produced by Javelin builders.

Chains register ahead of time to opt into a shared auction that allows Javelin builders to bid on a shared slot across chains, enabling them to provide composability to users and applications. These shared slots are done in epochs that last 12 seconds.

A builder bids for the right to build across all chains on The Composable Network for a given epoch. Blocks are built and sent to the chain in time with the chain’s blocktime. Builders switch every epoch.

Chains benefit by unlocking cross-chain composability with Javelin while being able to maintain flexibility in their stack and allowing them to have their own block time without giving up any revenue.
