this video is proudly brought to you by wwbd with links our official sponsors for cohort [Music] 11 react is actually JavaScript library used for building a front end for user interfaces whereby users can come and see whatever is happening on the dabs web 2 basically uses um database a centralized database and data is stored on centralized servers for the web three we have which has a decentralized nature you stored on the blockchain the blockchain technology and we look into um how data is actually stored so from the front end to the back end where data is seen on the client to the server that is um for the web two on the web three data is being stored on the blockchain in a decentralized nature and we make uses of make use of smart contract um on the ethereum blockchain to store data so basically um these are the core areas in which you know Web Two differs from web [Music] 3 other characteristics of real this is does not use the normal D is a virtual Dome is also a component based architecture and it allows proper State Management to HS so as the architecture goes um the front end facing UI would communicate with a wallet beit metal mask or connect wallet or whatever wallet may be now that will to handle signing transactions that we made to a node which has a copy of a particular blockchain any particular l1s there are um ethereum Bitcoin um wherever respective L ones that there are so what a node is basically is that it's a dedicated system that actually runs a replica of a particular blockchain that is it has the respective um first of it has the um needed software that it needs that's required to actually have a replica of all the data that been stored in particular blockchain and then Grant the respective users access to communicate with that particular blockchain be it's reading data from it or writing data to it or basically interacting with a particular smart contract um via that node and also carrying out transaction on that node Serv as a distributed um replica for that particular blockchain so um for that to be carried out the respective node service providers out there the usual suspect would be um Alchemy and infura they already grants like a end point to frontend applications that communicates with them and then in turn communicate to um communicate with the respective um information has been held by that node um copy of the particular um blockchain that it's um serving or running a replica [Music] for yay
