Before the introduction of the bitcoin lightning network, scalability was a big problem that causes delay in transactions and higher fee and also has a limit to some certain extent, an expressway was made and channeled through the bitcoin lightning network under the protocol for layer 2 protocols for transactions, and ever since this, it has been permanently solved
Bitcoin mempool has not been congested except certain time, especially during a very massive bull run, there can be high mempool congestion. But most of the time, the mempool is not congested and low fee transaction fee can be enough to get transactions confirmed in the next block or few blocks away.
ordinals that we recently experience is not as a result of scalability, but something that seems a bug on the bitcoin blockspace on the blockchain, NFTs inscriptions could place dager on the network later in future by some developers launchi attacks on bitcoin nodes through this.
Ordinals and Inscriptions is beyond NFTs, it was also the start of what people called bitcoin tokens like BRC-20. No nodes can be affected by Ordinals.
But why are the big exchange and non custodian exchange not supporting it though
binance is planning to.
Although some exchanges are supporting it too, not that it is so bad to the extent that few exchanges are not supporting it. About your questions, it is likely because those exchanges are making huge profit from bitcoin. They also have their side chains, like the Binance BNB Beacon Chian and the Binance Smart Chain for bitcoin which are actually not bitcoin, but altcoins.
This is what they said in the link on my post
I saw it too and I perfectly understood you correctly, but you do not have to agree with everything you see on the news, while you need to read some news in details before not leading to rumour or misunderstanding. Some news are also just of false information.
I hope you understand how Bitcoin lightening network works, the transaction dey confirm for another layer like dem polygon dem wey be layer 2.
The real bitcoin are the mainet and lightning network. All other networks are altcoins and some people referred to them as side chains. Lighting network is layer 2 like you meant, but not side chain because it is actually bitcoin sent to offchain layer to be used for lower and faster transactions. Which can be sent back onchain.
Lightening network na layer 2 e be the transaction no dey happen on the Bitcoin mainnet and na why people been dey get second thought about the whole solution.
Most wallets are not supporting it. Some exchanges are not supporting it. If it is not your lightning node, it is not your coin. Some people are afraid of attack. Also not good for huge transactions amount.
But some wallets are making lightning network easier to use as they are only generating payment invoice for users, but this is centralization.
But those who didn't adopt lightning network before, have been able to cope with the scaling problem before this recent attack on Bitcoin, with this can I say the scaling problem was not too serious before this recent attack?
Yes, not as serious as this. But it is worth knowing that this is not an attack. It only makes bitcoin to have more usefulness. Something useful should not be called an attack, but I noticed that almost all established bitcointalk members that posted about it all against it except one that I know among them that is a miner. Some coins like litecoin and doge have their own tokens now which their community well accepted and not a problem because they are not have scaling issue. I do not mean bitcoin is not superior and better, but why want to fight what makes transaction fee to be more replacing mining reward.
