LayerTree: a non-custodial scaling solution on bitcoin that connects to Lightning. A single UTXO can hold the balance of millions of users as an off-chain Merkle-sum tree.

Using covenants, one UXTO can be shared by a million users. Any user can leave at any time in a single transaction. Users don't need to be online to receive. Funds never time out. Transaction introspection techniques permit batched exit from the system in a single transaction w/o any pre-signing.

LayerTree is the next step in bringing bitcoin to billions.
