I also think L2 layers are not genuinely a Bitcoin network but the issuer's token's network.  Since Bitcoin programmability is limited I do not think that it can support advanced smart contracts unless it is done outside the natural layer of Bitcoin.  But as long as these L2 layers are not as intrusive as BRC-20 that affect the Bitcoin network congestion, I do not mind them developing this kind of smart contract because it enhances the applicability of Bitcoin to real-life case use.


I agree, anything outside the Bitcoin network that issues a coin or token is an altcoin.

Is this not one of the reasons why we will keep advising that not everything you see online are true, we cannot accept whatever they said online, some are doing so in other to just get traffic to their platform because they know that once you heard about something new and uncommon, you will hasten up try to read about it, that is why some of them were sugar coated mouth and are only being sponsored for doing that, bitcoin network cannot be combined with smart contract, even though they all make use of the blockchain technology, their networks are different.

The Bitcoin Blockchain is a secure store of data, and if brilliant people are able to increase it's usefulness - without using altcoins/tokens, then that is a really good thing.








I looked at brief descriptions of quite a few L2 projects. Isn't there at least one or more which do not use new tokens, they are a "true layer on top" which helps give Bitcoin more powerful smart contracts? ....and all the transactions are securely settled in BTC. Yes, I did see at least one of those, I think.




FYI: The OP has been edited:

Edit #2: The Title says Bitcoin Ecosystem (Blockchain) not BTC coin. Please, read the details, thank you.

While it is true that projects of Layer 2 are highly contributing to the functionality of Bitcoin, it should be frankly noted that between the original Bitcoin blockchain and the Bitcoin ecosystem created by these L2 solutions lie great differences. The Bitcoin blockchain itself remains a secure, decentralized, and immutable repository for storage and transfer. Its main function has been to sustain the integrity and security of transactions about Bitcoin, done through its consensus mechanism called proof-of-work.

Nevertheless, we shouldn't ignore the fact that not all L2 scaling solutions are risk-free. The greater the intricacy of a system, the more challenging it will be to maintain security, where users might show concern for the trust models such systems introduce. While these scaling solutions increase the feature set for Bitcoin, they also make it dependent on other secondary systems, like the Liquid Network's federated consensus, which may also introduce centralization concerns.

The only "true layer on top", sufficiently developed and actively researched and maintained is Lightning. Everything else is just another blockchain.

Both Taro and RGB are not reusing bitcoin as currency. They are networks that issue new assets. You cannot enter with a bitcoin amount in any of those networks and be certain that you will return back on-chain with the same amount. There's no on-chain transaction which will can be broadcasted in case you want to unilaterally return some of those assets for bitcoin.

Honestly, the contracts supported on Bitcoin are limited in their use case, like using Taproot smart contracts with limited features, but when it comes to smart contract experience as we see in the ETH's ecosystem as DeFi and other Dapps, it's because of the limitations with language.

For L2 as you've said they dont damage the main chain agreed, but they are not the main chain this is what we need to realize.

Yes, because they are basically on top of the bitcoin blockchain so it doesn’t affect actual bitcoins because the native bitcoin blockchain does not really support smart contracts. There’s also WBTC, which is again not actual bitcoins, that is on the ethereum blockchain that can be used in smart contracts. It’s just basically erc20 that is pegged 1:1 to bitcoin.

Bitcoin is a project that was created in the 21st century, but it will also exist in the 22nd century. The last Bitcoin will be mined around 2140.

What will Bitcoin be like in the 22nd century? Will it really remain unchanged? Exactly the same as it is now?

In my opinion, Bitcoin should also develop technologically. Various alternative cryptocurrencies are essentially experimental laboratories. They test various technological, software, financial and social innovations. The best of them (I believe) will eventually be implemented in Bitcoin.

Therefore, I am quite tolerant of projects such as ordinals and runes, despite the fact that they negatively affect the size of commissions in the Bitcoin network.

Experiments are also needed. All this will make the Bitcoin network better and more useful for users in the future.
