The Blockchain trilemma is a peculiar concept coined by the founder of Ethereum, Vitalik Buterin. The Blockchain trilemma talks about the three primary issues including decentralization, security, and scalability encountered by every developer while building Blockchains. Ultimately, it forces them to sacrifice one aspect of the Blockchain for the sake of the other two.
It has become one of the widely accepted concepts across every decentralized ecosystem. However, the latest innovations suggest that introducing a diversified range of Layer-1 and Layer-2 can overcome the obstacle, solving the trilemma once and for all.
