How many transactions are in a block Bitcoin?

Right now, each new block in the chain must be 1MB or smaller. This limit is hard-coded into Bitcoin. A typical Bitcoin transaction is about 250 bytes, so that means that 1MB/250bytes = 4000 transactions can fit in each new block.

Where are blockchain transactions stored?

Blockchain is decentralized and hence there is no central place for it to be stored. That’s why it is stored in computers or systems all across the network.
