What is OP_CAT and should OP_CAT be restored?

Simply put, UTXO Stack is the "OP Stack + EigenLayer" of the Bitcoin ecosystem.

Mode Network is a modular Layer 2 based on OP Stack focusing on the Defi track. It adopts Optimism’s Bedrock upgrade and can reduce costs by more than 95% compared to the Ethereum main network.

Teams such as Bitlayer and Citrea adopted the BitVM bridge solution, introduced pre-signatures, and combined the idea of ​​channels, allowing users to limit the processing flow after deposit execution before officially depositing, and not giving the cross-chain bridge official the opportunity to misappropriate user deposits.

One of the best ways to implement zkEVM is through Polygon because of its strong business development capabilities.

After completing a series of Staking and Restaking community incentive activities, CyberConnect, a new social public chain built on OP Stack, was officially launched. What potential impact will the new chain Cyber ​​bring?

With the help of technologies such as Taproot and BitVM, more complex off-chain contract verification and settlement can be achieved within DLC, while combined with the OP challenge mechanism, minimization of oracle trust can be achieved.

Bitlayer leads the BitVM-based Bitcoin second-layer solution, adopting layered virtual machine technology (Layered Virtual Machine), using zero-knowledge proof (zkp) and optimistic verification (op) mechanisms to support various types of calculations.
