Publicly verifiable randomness from the drand League of Entropy beacon, attested and times
Publicly verifiable randomness from the drand League of Entropy beacon, attested and timestamped. Use it for a fair draw between parties who do not trust each other: a distributed network emits one signed value every 30 seconds and no participant, Soren included, can choose or predict it. Soren refuses to attest a round that does not verify, and you can check the same round yourself at api.drand.sh.
