Lightning Labs Proposes LayerTree, intended to allow approximately up to 1000000 users to share a single UTXO, but it cannot currently be deployed directly on Bitcoin mainnet.

Lightning Labs Proposes the Bitcoin scaling solution LayerTree: approximately up to 1000000 users share a single UTXO BlockBeats reports that October 16，Lightning Labs proposed the Bitcoin scaling solution LayerTree, designed as a non-custodial architecture that could allow approximately up to 1000000 users to share a single UTXO and connect to the Lightning Network. Balances are recorded in an off-chain Merkle-sum tree, with the shared output committing to the tree root, and users able to exit unilaterally in a single transaction. The solution depends on Bitcoin consensus-layer changes that have yet to be activated, such as covenant-related opcodes, and cannot currently be deployed directly on mainnet. The project describes it as a design and reference implementation; the opcodes used remain proposals rather than current consensus rules.

AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
LayerTree envisions placing the balances of many users in an off-chain tree structure, with a shared UTXO committing to its root. Users do not need to rely on a custodian and can exit independently with a single transaction. However, the Bitcoin rules required for it to operate have not yet been activated, so it cannot currently be used directly on mainnet.
Why it matters to readers
If the rules required by this design are activated, it could allow many users to share a single UTXO and connect to the Lightning Network, thereby becoming a Bitcoin scaling solution; for now, it remains a design and reference implementation.
For beginners, the key point is that “approximately up to 1000000 users sharing a single UTXO” is a design target, not an indication that approximately 1000000 users are already using it, nor that it has already launched.
Risks and unknowns
It remains unclear whether consensus-layer changes, such as contract-related opcodes, will be activated.
It has not yet been confirmed whether LayerTree can be deployed on Bitcoin mainnet.
The original text does not provide information on testnet deployment, security audits, or actual user adoption.
“Up to approximately 1000000 users” has not yet been validated on mainnet.
