$CKB CKB is the first Bitcoin Layer 2 solution that is completely isomorphic to BTC, built on the PoW and UTXO models. This unique architecture not only enhances compatibility with Bitcoin, but also empowers various assets on BTC through smart contract functions. This allows developers to create and manage complex financial products and services more flexibly in the BTC ecosystem.

In addition, CKB is actively developing its second-layer lightning network solution, which aims to achieve interconnection with BTC's lightning network. This will greatly enhance the practicality of the Bitcoin network, allowing BTC's first-layer assets to achieve censorship-resistant, permissionless and decentralized two-way circulation between BTC and CKB.

In this way, CKB greatly expands the use cases of Bitcoin.

In order to help more developers join the BTC and CKB ecosystems, we will hold a series of developer open classes from May 20 to May 28.

The course aims to provide an in-depth explanation of CKB's core technology, smart contract programming, and asset issuance, helping developers better understand and practice BTC and CKB development, unlocking the potential of the first layer of Bitcoin assets.

Friends who participate in the course and complete the homework can also participate in the red envelope grabbing at the end of the course~
