Limitations of Blockchain. What are they?

[rhayot]

Blockchain's limitation are known to its complexity because blockchain technology requires new vocabulary to installed. It is made of  cryptography codes, but there are some details provided by the internet about glossaries and indexes that are easy to understand for us to be familiar with it. Another thing is the human error, because if a blockchain is used as a database, the information will be inputted in the database must be a good quality. The data stored on a blockchain is not inborn safe or trustworthy, so if that would be the case it is obvious that you need to have a back up for those data that you're going to stored. Basically, blockchain technology is an undeniably master piece invention because it is a decentralized technology but still blockchain isn’t perfect.

I think one of its limitations is that as bigger data are embedded into it, the larger the transaction fee and the slower it may process. Ofcourse, as more people indulge into that specific blockchain, more files and data will be stored leaving some of it unconfirmed. This delays transactions.

I think may be its the scalibilty but pardon me as i know not much about it. The term i just heard it from my friend

don't listen to friends,listen to nullius
you can read the topic and find many interesting things that can be called limitations of blockchain
all of them(or at least the majority of them) were discussed at length,plus some interesting insights into the most popular
misconceptions about quantum computers resistance,cryptography and fire hydrants

There are many drawbacks some of which are Network size, network speed but not human error as its an automated public ledger

Can't scalability issues be solved through a sidechain ?

This is the Bitcoin board so I'll be speaking about the Bitcoin blockchain....

The first and most evident "limitation' of blockchains is scalability.
Public blockchains are very hard to scale especially on-chain.
This is because of the way bitcoin achieves consensus; most nodes must verify a transaction (or block) is valid.
If the block size is too high then a lot of nodes will be cut off and this leaves the power of the network in the hands of a few people which leads to centralisation.
Also, if the block size is too low then obviously a lot of transactions won't be able to fit and this leads to high fees during high thoroughput periods as people will pay more for their transaction to be mined.

I made my research about blockchains limitations and one of which is Human Error. Here it says,
If a blockchain is used as a database, the information going into the database needs to be of high quality. The data stored on a blockchain is not inherently trustworthy, so events need to be recorded accurately in the first place.

The phrase 'garbage in, garbage out' holds true in a blockchain system of record, just as with a centralized database.

I still havent got the meaning of blockchain means what are they and why are they even used?

Then, try your best to digest this: Wikipedia/Blockchain

So you're saying that, if a monkey inputs a data into a blockchain-based database and the result was incorrect or an error, the problem came from the blockchain?
No, "human error" is not a blockchain limitation. If it was, Everything that involves human interaction has "human error" limitation.

I think the biggest task we face is scaling without sacrificing any of the underlying privacy and security problems it done so well to solve
