Cryptographic sortition

WebAlgorand's cryptographic sortition posted September 2024 There are several cryptocurrencies that are doing really interesting things, Algorand is one of them. Their breakthrough was to make a leader-based BFT algorithm work in a permissionless setting (and I believe they are the first ones who managed to do this). WebAlgorand uses cryptographic sortition to select users to propose blocks for a given round. When a block is proposed to the blockchain, a committee of voters is selected to vote on the block proposal. If a super majority of the votes are from honest participants, the block can be certified.

WebNov 21, 2024 · Cryptographic sortition is an algorithm for choosing a random subset of users according to per-user weights; that is, given a set of weights and the weight of all users , the probability that user is selected is proportional to . The randomness in the sortition algorithm comes from a publicly known random seed. WebCryptographic sortition allows the network to compute, without communication, which node will do what, at what step, and guarantees none of this is even observable to an attacker until it is done. The network is essentially a hive mind. This is called player replacability.
