gui VS omnicore

libbitcoin isn't a company. It's an alternative C++ implementation (https://github.com/libbitcoin) to the Bitcoin Core (https://github.com/bitcoin/bitcoin) implementation. Bitcoin Core is the one originally from Satoshi. Libbitcoin came in like 2011 or so iirc and was led by Amir Taaki. Libbitcoin is a lot less popular than Bitcoin Core, as you can see on the github stats.

The code is open-source: https://github.com/bitcoin/bitcoin/

That would make Eve online, Second Life, and other games illegal since people trade their digital assets all the time

>Comparing Bitcoin to free software seems similarly disingenuous.

Bitcoin is free software. https://github.com/bitcoin/bitcoin

Yes a government can. Bitcoin specifically is open source: https://github.com/bitcoin/bitcoin. The ledger is public so as you pointed out there wouldn't be more details.

Bitcoin Core integration/staging tree - 66.3k stars

Different implementations(core, knots,btcd,bcoin,libbitcoin, ....) have different ways of coming to consensus. The most popular implementation called core https://github.com/bitcoin/bitcoin follows these guidelines https://github.com/bitcoin/bitcoin/blob/master/CONTRIBUTING.md

You can read every line of code right here on GitHub.

Also, read the source code It's on-line, for free https://github.com/bitcoin/bitcoin

Why is the source code a single file? No real code project that I've ever seen is built on 1 file. Take a look at BTC for example, that's what a real code project looks like.

It got rebranded Omni layer: https://www.omnilayer.org

There is usually no point to using a distinct blockchain as well as one can use a secure blockchain like Bitcoin without the need of inefficiently replicating all its work and security and timestamp with https://opentimestamps.org/ or http://coloredcoins.org/ or creating assets with https://www.omnilayer.org/ or https://github.com/rgb-org/spec or https://blockstream.com/2018/07/02/liquid-issued-assets/ without the need for any distinct blockchain and the overhead this requires.

Perhaps you could ask on the litecoin sub? From the name I guess it is similar to https://www.omnilayer.org/ which exists on BTC and which is used to send USDT over the BTC network. If that is all, it would allow you to add a bit of information to a LTC transaction. Possibly it is more.

Concerning the ability of running tokens ("colored coins") on the Bitcoin network, such as for example USDT, and referencing those, the omnilayer system encodes all of that in terms of the normal Bitcoin scripting language: https://www.omnilayer.org. I remember reading a bit in its documentation a few years ago, but I don't remember any details. Omnilayer undoubtedly also has a system to reference its objects, but I have no clue how.

Tokens exist on BTC, and they are just as expensive to move around as BTC itself. Most well known token is probably tether. See https://www.omnilayer.org/
