- Lightning Network
- Sharding
Is there any other methods which might solve the bitcoin scalability problem ?
Are we talking theoretically, or in practice? Because I don't think sharding will ever be implemented in Bitcoin. It completely trades off redundancy -- the backbone of the P2P protocol -- for scale. Ethereum is being forced to consider it because of its unsustainable throughput demands, but the "decentralist" camp won't let it happen in Bitcoin.
Maybe we should start by identifying the exact issue. How do you define this "Bitcoin scalability problem?"
Thanks for your comment. I would describe Bitcoin scalability problem as (correct me if I am wrong) - inability to process a large number of transactions (like for example VISA). which result in impossibility to implemented Bitcoin as normal daily payment method for large amouth of people.
