Topic: How Is Bitcoin Blockchain Different From Altcoin Blockchains? (Read 297 times)

bitcoin and blockchain is different from each other because bitcoin is a digital currency, while blockhain is a databases scattered in all parts of the world that is why even if one goes down there will be no interuption that will occur, blockchain is important for digital currency to run, correct me if i'm wrong

I don't know whether we can have a site that has all stats on total hashrates of each cryptocurrency network.

blockchain itself is not a "software" it is a database. as the name suggests it is "a chain of blocks" which means blocks of data that each is linked to the previous one like a chain.
considering the fact that a very large percentage of altcoins have copied bitcoin, their blockchains are exactly the same.

Blockchain is not an engine, it's just a data structure, and it's really wrong to think that it's some sort of a platform or the most important part of cryptocurrency. Because other parts are just as important, there wouldn't be crypto without consensus algorithm like proof-of-work, there wouldn't be crypto without modern cryptography, there wouldn't be crypto without peer-to-peer network protocol and so on. Blockchain is just a part of something greater.

Lol, good question from someone who actually wants to learn, blockchain is the main engine that coins run on, Bitcoin has its own, Ethereum has its own, Seele has its own, even the new relictum pro is planning on build it's own blockchain that is more faster than older  projects

but on Altcoins there are some added features, like scalability, smart contracts and so much other stuff that is being added just to improve its performance.

As the quote goes "there is no utopian system". What we have is a mixture of both sometimes.

If the Supply of Bitcoin is centralized while the block chain is decentralized it can be said to be a hybrid cryptocurrency model.

Will the hybrid model be more effective?

This is one of my favorite technical explanations on this thread so far. The bitcoin coin owners are decentralized same with the miners.
You mean a server makes a platform to be centralised? Are there altcoins that use servers which make their digital currencies centralised?

it's a little hard to explain but i'll try. cryptography comes in mostly in two parts in bitcoin: the proof of work (hash algorithm) and asymmetric or public key cryptography. decentralization works partly with you creating and controlling your own keys and handling your own money without needing a third party using asymmetric cryptography, and partly with the entire network being peer to peer so there is no "server", no "centralized authority" to decide which transactions to accept and which to censor. it is only peers who enforce all the rules as a very large community of individuals. the miners as another part of this network are also decentralized as they are also individuals and are spread around the globe, they are all competing to find the same solution (step 3 above) using that hash algorithm.

considering that you can only create tokens on another platform i don't think we can even call these two "blockchain development languages" because you aren't developing blockchain you are just writing contracts.
additionally it is just hyped up because of the ICO craze that we had a couple of years ago with all the pumps that happened.

But this is what I mean  by the question you threw light on. What I mean is this; I often hear that blockchain and cryptography are interwoven.
So, my question is actually to know how these work to produce the decentralised non fiat currency like bitcoin.

In my research I found out that solidity and simplicity are two of the leading blockchain development programming languages.
What do you have to say about these technical issues?

Most problems focus on scalability, low fees, and privacy.

 - Scalability & low fees: All altcoins attack Bitcoin in this respect, they have nothing to provide except low fees and short confirmation times, so you find that all currencies claim to be the best in that. Litecoin, BitcoinCash, BitcoinSV^*,....etc.

 - privacy: We all know that Bitcoin transactions can be traced, so some currencies try to make this impossible.

In short, if you examine the currencies carefully, you will find 5 or 8 models that are unique and the rest are duplicates.

Can you point out one of such deficiency in bitcoin and which altcoin is attempting to solve it. Thanks

Bitcoin is a protocol. What distinguishes it is the amount of consensus that it possesses and the large number of people who agree to follow that "law" and therefore has a more fundamental value than Altcoins.
In fact, most alts are attempts to solve some Bitcoin problems or create copies similar to it.
So, continuous development is what makes it unique.

I think this answer is general and you can view more details here ----> https://www.youtube.com/watch?v=_Wg6aPEkc5k.

If you want a comparison with a particular Altcoin, you can ask the question again.

blockchain itself is not a "software" it is a database. as the name suggests it is "a chain of blocks" which means blocks of data that each is linked to the previous one like a chain.
considering the fact that a very large percentage of altcoins have copied bitcoin, their blockchains are exactly the same.

i'm not sure what you are asking here, but as far as blockchain is concerned i can think of three topics: the block structure, the way the blocks are linked together, and the method used to set a cost for creating the blocks.

1) the block structure is not really that important. it is the way transactions are serialized and put inside a block, what part is there to be hashed for part 3,...
2) the way blocks are linked together is (in bitcoin) with each new block having a reference to the hash of the previous block. there are other methods in different chains that someone more familiar with them should answer here.
3) the "cost" is the proof of work for bitcoin and all the similar coins which needs to be an irreversible one way function that could be adjusted to be fast or slow depending on the needs of the network (difficulty) and it should produce a result that could be compared with a desired target. the function is usually a hash function (double SHA256 in bitcoin, Keccak256 in ethereum, scrypt in litecoin, prime gap in GapCoin,...) and the target is usually an integer (little endian 256-bit number in first 3 and a set prime gap in GapCoin).

Since you mentioned it. There is no prime difference how blockchain of bitcoin works differently on altcoins. Satoshi's goal in layman's term is to create a peer to peer enviroment that doesnt restricted by such authority or entity. Like what has been explained by @pooya87 this is major building blocks that linked together called chain. Now for these chains to connect we execute transactions that has been systematically recognized in a network.

Difference to other blockchain will be restricted to speed, weight, algorithm and scalability of their using consensus.  But if your looking for more detailed comparison you can refer to this simple guide. What is Blockchain Technology - A step by step guide for beginners
