Say Goodbye to Miners, and Hello to Builders, Proposers and Verifiers: Sharding and Danksharding
I have just moved house and currently live near other houses being built. The one thing you notice is that there is considerable activity in building parts of houses, and where each house is at different stages of development. This is a distributed model of building a house, and where many houses can be built at the same time. If we build one house at a time, we would end up with bottle-necks, and where we would continually have to gain approval for every part of the house build. In a distributed approach to house building, each house can be built independently of the others.
And, imagine if every time a worker had to do some work on the house build, they had to put a cost on their work, and then bid for the work to be done. For this, we normally bundle up all the costs of all the work into a contract and then get each builder to bid for the whole house build.
Well, the world of Ethereum is now taking these approaches and moving towards the increased distribution of its work. This will hopefully move away from slow processing and high gas fees. One of the key implementations in this new model of Ethereum is the move away from miners and proof of work, and towards builders, proposers and verifiers, and which should allow Ethereum to scale-up.
