| > Yes and no: it's not a blockchain. It's relying on the fact that the drand network is producing distributed, verifiable randomness using a threshold scheme with distributed key generatio Hm ok, it's just that there is a lot of blockchain terminology used throughout drand like "testnet", "mainnet", "chain" and so on. Seems very similar to a blockchain with similar attack scenarious but I guess it's not exactly a blockchain but somewhat similar? > Currently it relies on the League of Entropy network, run by Cloudflare, Protocol Labs, Ethereum Foundation, Kudelski Security and other organizations, including multiple universities. So the security is relying on the fact that the network's goal is to produce public randomness, and that parties have no reason to collude. For instance the League of Entropy is used for leader election and randomness by Filecoin, so it's already "securing" a lot of things, adding timelocked data on top seems like a nice way to use the network. I see so there is a closed group of more or less well known entities which hopefully wont be dishonest to a major degree. Closed group being the key here because that prevents whole range of attacks, most importantly sybil attacks. So the trust in the system derives from the trust into the participants. Without researching it more I would guess that during encryption it might use the public keys of the nodes plus the round number with the threshold scheme and when the round finally arrives, the nodes then publish their private keys for this round? I think I have a better idea of the system now. Judging by me being not the only one here who didn't understand how things work on a high level maybe the README could be expanded a bit. That would be great. |
