Buterin published a blog post yesterday, December 6th, under the title “Endgame.” In it, he presented a thought experiment for how a big blockchain, defined by high block frequency, thousands of transactions, and high block size, can still be considered trustless and censorship-resistant.

Usually, this level of scalability comes at a price, and the price is centralization. However, Buterin then provided a solution that does not address the centralization issue itself but offers a roadmap for the implementation.

Buterin suggested the introduction of a second tier of staking that would use low amounts of resources for carrying out distributed block validation. With the updates he suggested, it would be possible to create a chain where block production remains centralized, but the block validation is trustless and highly decentralized. More than that, it would have a specialized anti-censorship feature that would prevent block producers from censorship.

Finally, he concluded by sayings that there is a high probability that the block production would remain centralized regardless of what path to scalability the project takes. However, his solution offers to make certain parts of the process decentralized, which is still a step in the right direction.
