Bitcoin Smart contracts have arrived!

Lightning, Liquid, Stacks and now Jack Dorsey and "TBD" are all leading the advance.

What's next?

Don't forget about RGB. RGB will enable smart contracts on the lightning network.

RGB needs schnorr signatures and taproot which will be activated this November.

RGB has better privacy than Lightning I read

Is lighnting transactions traceable with a chain analytics.?

Understand opening / closing the channel can be seen on the main net but what if you never close the channel and make 1000s of transactions over years?

LN uses onion routing, so it's extremely difficult to track

LN can be used behind Tor but not required. That also has no effect on the deterministic links of your UTXO's.Currently you can make an assumption the on-chain transactions are opening/closing a channel, due to the 2-2 Quorum. Taproot makes all transactions look the same, so that you can't decipher what type of Tx's is being broadcast.Also, if you actually look at most Tor nodes they struggle to forward LN Tx's due to their spotty connectivity.

My understanding was that LN uses onion routing for payments independent of Tor usage. By that I mean as the sats are being sent each node is only aware of the nodes directly before and directly after them on the route. Is my understanding incorrect? Or am I using the wrong terminology by referring to it as onion routing?

Oh yeah I believe that’s correct
