Expanding Possibilities with Rollups

PreviousEnhancing the Bitcoin Ecosystem with Smart Contract CapabilitiesNext$XSAT Tokenomics

Last updated 7 months ago

exSat, powered by Antelope, provides a modular blockchain solution that enhances the Bitcoin ecosystem. It serves as both Data Availability (DA) and settlement layer within rollup systems, streamlining the deposit and withdrawal processes and bolstering trust in Bitcoin L2 solutions. Developers can leverage exSat to create secure and efficient Bitcoin L2 solutions with minimal effort and resources.

exSat provides the DA and settlement layer for BTC. This naturally enabled all the Rollup solutions including Optimism (OP) and ZK. As both DA and settlement are performed on exSat, we don’t need Data Availability Sample (DAS) for data publication. The verification of Zero-Knowledge Proofs (ZKP) from Bitcoin L2 Rollups are executed on exSat.

This modular approach allows developers to customize Bitcoin L2 solutions to meet diverse requirements, promising a flourishing ecosystem of DApps as Bitcoin continues to evolve.

For the modular scaling solution architecture, please refer to the figure below.
