What is the blockchain trilemma?

This phenomenon is known as the blockchain trilemma, which was originally coined by Ethereum co-founder Vitalik Buterin as the scalability trilemma. A major reason for the gridlock is the fact that decentralized platforms grow in size as usage increases. This is evident in leading projects like Bitcoin and Ethereum.

What is a blockchain record?

Such a record could be a list of transactions (such as with a cryptocurrency), but it also is possible for a blockchain to hold a variety of other information like legal contracts, state identifications, or a company’s product inventory.
