Scaling blockchains with sharding

Before diving into the concept of sharding, it is crucial to understand the importance of sharding. Sharding is proposed as a solution that can, in theory, overcome the challenges of scaling blockchains with minimal trade-offs. According to Vitalik Buterin, the founder of Ethereum, typical blockchains are bogged by the Scalability Trilemma - scalability, decentralization, and security. 

For the most part, simple scaling techniques can only achieve two of the three properties in the Scalability Trilemma. Successful sharding, on the other hand, will allow blockchains to scale without facing the Trilemma. A deeper understanding of sharding is therefore beneficial for a sustainable future for blockchains.
