At ethereum's flagship conference, Devcon, project creator Vitalik Buterin revealed he has been quietly working on a new long-term plan for the future of the blockchain network. What he called a "modest proposal," it's perhaps better described as a three-to-four-year roadmap for ethereum's technical development.
Notably at the heart of the vision is a long-in-the-making technical change to ethereum called "sharding," and while always expected to be included in the protocol's plans, today Buterin proposed what might be his most solidified strategy for the technique to date.
As such, the roadmap hints at problems yet to be solved on the platform, and as the emphasis on scalability for project developers. As ethereum nodes need to store everything that ever happened on the network, Buterin stressed that there's a need for solutions that mitigate expensive storage costs that could escalate exponentially as the system expands...
