Blockchain trilemma

Scaling the Bitcoin Blockchain The limit on the size of each block however, has changed several times. In 2010, Satoshi Nakamoto established the rule that no block could exceed 1MB in size . In 2017, that limit was altered via the SegWit upgrade, which raised the limit to 4MB.

Scalability within Bitcoin means the limitations of the blockchain for the processing of multiple transactions . As already described, individual transactions are collected in a block. The maximum size of a block is clearly defined in the Bitcoin protocol.

Why is Scalability Important for Blockchain? Scalability is an important requirement in blockchain networks as it refers to the network’s ability for supporting higher transaction throughput . Therefore, scalability is highly essential for the future growth of blockchain.
