Merlin Chain's Bitcoin Layer 2 design
Merlin Chain is a native Layer 2 solution engineered to empower existing Bitcoin Layer 1 assets and protocols. With an integration of the ZK-Rollup network, Merlin Chain brings additional improvements to the native Bitcoin ecosystem: zero-knowledge and fraud proofs submitted to Bitcoin, economical efficiency to make Bitcoin fun again
Merlin Chain is designed to unlock Bitcoin's full potential by creating an interoperable, scalable, and robust ecosystem. With its mainnet launched recently, Merlin Chain promises to bring about innovation that goes beyond just fast and cheap transactions.
When we talk about the Merlin Chain ecosystem, we can interact with a wide range of Dapps that bring numerous use cases to the community: from various developer tools to staking, DeFi protocols and traditional services of swaps and bridges. What’s interesting is that some of them recently confirmed airdrops and reward campaigns.
Here’s everything you may need to know about them.
