    0/ Many people asked me recently why does the alpha version of the EDI blogs.ed.ac.uk/blockchain/202… count pools as single entities when measuring decentralization and not pool members. To answer this question yourself, answer the following 3 questions

    I am very excited to share our open source simulation engine for blockchain reward sharing with @_LadyChristina_, all those interested in how systems like Cardano behave game theoretically are welcome to perform their own experiments and/or extend it blogs.ed.ac.uk/blockchain/202…

    glad to see that bimodal “liquid” staking is being considered in Ethereum. We did the first research on this in arxiv.org/abs/1807.11218, and our rewards sharing scheme was implemented in Cardano. for further context see the blog post iohk.io/en/blog/posts/…

    (1/3) Decentralization can only be measured taking into account multiple different layers of a blockchain system. I am very happy to share that we just released the alpha version of the tokenomics layer of EDI, see groups.inf.ed.ac.uk/blockchainlab/…

    We are officially launching today the alpha version of the EDI. The EDI is not a number or a graph! It is a framework, set of tools and graphical interface for the blockchain community to collaboratively and transparently measure decentralization - read: blogs.ed.ac.uk/blockchain/202…

    Measuring decentralisation is one of the hardest problems in the blockchain space with many implications of practical, security and regulatory importance. The EDI team has released its first measurement tool for the consensus layer - read more here: blogs.ed.ac.uk/blockchain/202…

    4/ In all three questions the answer that matters relates to how many distinct and independent pools exist in the blockchain system - not how many members each one has.
