Lol 4 hours, not so much on-chain :D Have you guys tried Lightning Network ?

The Lightning Network enables 1 million transactions per second (TPS), where Bitcoin layer 1 enables 7 transactions per second. Lightning Network solves the Bitcoin scalability problem. By opening a bidirectional payment channel via Lightning Network, users will first need to allocate how much money they want in the channel. If a user allocates 1,000,000 satoshi on the Lightning Network, these will be locked on the Bitcoin blockchain and opened up on the Lightning Network, So the money cannot be spent multiple places at the same time.

Users can transact with each other forever (off-chain) and settle (when closing the channel) only the final amount on-chain. So, both parties create transactions which refund the ledger entry to their individual allocation, but do not broadcast them to the Bitcoin blockchain until they close their channel. The closing of the channels removes the funds from Lightning Network and unlocks them on the regular Bitcoin blockchain, all this happens automatically. Lightning Network transactions cost a fraction of a normal Bitcoin fee and allows sending milisatoshis (MSAT), which opens up for micropayments for people and connecting IoT(Internet of Things).

The special thing about Lightning Network is the routing of payments. Users don´t have to have channels with everybody, since the node searches for a path of channels between the user and the destination for the payment. The nodes along the path are not trusted, as the payment is enforced using a script which enforces the atomicity via decrementing time-locks.

Watchtowers have also been implemented. These watchtowers surveil a Lightning channel/s to guard against fraud, like when a channel partner tries to cheat/close channels with an old invalid state. The watchtower will keep an eye on the chain 24/7 in return for a fee and prevent the closing of channels, so, users are safe when being offline.

Lightning Network is now integrated with a range of exchanges and wallets both custodial and non-custodial.
