The final level to discuss is the presentation layer, which consists of the use of a website and web3 libraries in order to retrieve data from the blockchain to put on a web page, and in order to write data back to the blockchain in the form of transactions, usually using an integrated web browser blockchain wallet such as MetaMask.  The thing to realize here, is that the web site developer has complete control over how they present the data they retrieve from the blockchain to the user. They can present it as is, or they can alter some or all of it.  There is nothing about a blockchain that forces the web developer to be honest in this presentation, and I give an example in this video of how I did just that to Anthony Day in the SOULS website ( visit https://souls.fi/  for more ).
