Bitcoin layer 2 scaling

Development on Bitcoin is on fire lately!
After Ordinals, it’s time to focus on Layer 2 scaling solutions.
What’s new in the space? Let’s discover it in this thread!
Bitcoin has two very serious problem, which are linked one to another: scaling and lack of adoption.
Scalability, capacity of the network to process a large number of transactions quickly and efficiently.
Bitcoin’s scalability challenge arises from its design and the underlying technology it relies on, known as the blockchain.
Adoption instead, refers to the use, or willingness to use, the network in the society.
Scalability is a prerequisite for adoption: even if every single person on Earth decided to use the Bitcoin network, without scalability, there would be no adoption
