Each DAPP has its own blockchain?

I am learning blockchain technology. I read a lot of tutorials and I got the basic idea of ​​what a blockchain is, but I am confused by the fact that there are separate separate blockchains for individual DAPPs, and people who use this DAPP will only be part of this DAPP blockchain and what do the blocks in the Ethereum blockchain really contain?

If someone can clean my newbies, this will be very helpful. Thanks in advance:)

A dApp, which is a decentralized application, may or may not have its own block code. It depends.

If you want more implementation details, check out Ethereum Yellow Paper :

  • "Transaction" is described in section 4.3.
  • The “block” is described in section 4.4.

Each smart contract has its own Merkle Patricia Trie , which uses Blockchain, but this is more of an implementation detail.

I have described in more detail how Ethereum Storage works, taking into account gas and cost, and why you can use something else, I hope that can help you.
