Avalanche lets you natively bridge bitcoin to their network, and it lets you transact fairly cheaply (think my last transaction was $.15) and their consensus algorithm can reach finality pretty quickly. Typically around 2 seconds. But it also has smart contract support.
So does Solana, where transactions are $0.00001 and finalize faster than google's homepage loads.
Lightning isn’t decentralized though. They just reinvented PayPal.
