Kchannels is a new payment channel platform for Ethereum. It is non-custodial and trust-minimized, and its primary focus is on great UX. Among other things, it is well suited for commercial use-cases (think merchants and their customers).

Kchannels provides the standard payment channel features:

• fast transactions - no more waiting for blocks/confirmations; no more dealing with congestion

• low fees - no more dealing with expensive and ever-changing gas prices

• privacy - most transactions are not visible on-chain

It also has the following features:

• minimal infrastructure requirements - you don't need to install any software (even Geth)

• transaction finality - transactions are final as soon as they complete

• no special token - there is no special token anywhere in the system

• no network - we avoid all the complexity of sending transactions through a network

• no capital required to maintain channels - transactions are not bottlenecked by the need for additional funds in the system

• high scalability - Kchannels can scale horizontally to support thousands of transactions per second

Kchannels uses a powerful channel design:

• a channel can hold multiple assets (and transfer multiple assets in a transaction)

• an unattended channel can receive transactions

• fast and easy deposits/withdrawals at an open channel

• most users only need a single channel--ever--for all their needs!

Together, these features create a nice package that could open up the blockchain to lots of new (or at least known but elusive) use-cases.
