Nervos Network : enhances Bitcoin with RGB++ and layer-2 scalability

The key thing they're working on is this protocol called RGB++, which lets you use CKB as both an execution layer and a data storage layer for Bitcoin. This solves some of the limitations of the original RGB protocol, making Bitcoin more scalable and flexible.
Some of the standout features of Nervos:
🔸 Turing-complete smart contracts using their unique "Cell Model" - this is way more advanced than Bitcoin's basic scripting language 
🔸 Vertical scaling with RGB++, so Bitcoin can handle more transactions and data 
🔸 Compatibility with existing Bitcoin Layer 2 solutions like Lightning Network 
🔸 A custom virtual machine called CKB-VM to run contracts efficiently
