Block size limit: Bitcoin originally had a strict 1 megabyte (MB) block size limit. However, the introduction of Segregated Witness (SegWit) in 2017 changed how data is counted within blocks.

Each block in the blockchain is a digital container that permanently stores transaction data for the network. When new transactions occur, they are processed and bundled into a block.
