#Spark is a new payment solution with the goal to mitigate shortcomings of Lightning. Curious about your thoughts on this:

“Spark is a Bitcoin L2 that enables instant, dirt-cheap, and unlimited self-custodial transactions of bitcoin and tokens while also enabling users to send and receive natively via Lightning. It's open-sourced and secured by Bitcoin.

Spark Diagram

Spark is purpose-built for payments, and as such enables the following:

Native BTC

Full self-custody

Instant settlement

Extremely low fees

Native tokens (e.g. stablecoins)

Native Lightning interface without needing to run a Lightning node

Ability to scale to billions of users

1/n trust assumptions (or minority/n) with the risk only at the time of transfer, not in perpetuity

Unconditional unilateral exits

Capital efficiency (no pre-funding, liquidity lockups, etc.)

Exists without the need for a new Bitcoin OPcode or any Bitcoin changes (although improves when they're available)

What Spark is not:

100% trustless on day one

A new Bitcoin L2 launching a token”
