Making sure the Tezos blockchain is decentralized for ever.
Similarly to bitcoin’s difficulty adjustment, you could imagine decreasing the roll size as long as the Tezos Gini coefficient is above 0.5 and vice-versa.
This would deliver mathematical promise that “Richs won’t get that richer” while guaranteeing a number of bakers low enough to allow transaction volumes.
[The Gini coefficient is a measure of statistical dispersion ranging from 0 to 1. A coefficient of 0 would indicate an equal allocation to every wallet, while a coefficient of 1 would describe a dataset where the entire allocation goes to a single contributor. The Gini coefficient is easily computable with the Lorenz Curve.]
In 2017, the Tezos Gini coefficient of was 0.878 , which was higher than the Gini coefficient of the Ethereum crowdsale (0.832), or wealth in the world (0.804), the United States (0.801), and Switzerland (0.803).
0.5 is a random, but symbolic number. Feel free to own this idea and to compute an optimum static Gini coefficient.
