[DotSecurity2017] Verifiable Lotteries
In realms where randomness reigns—visas’ vagaries, audits’ allocations, tournaments’ tabulations—authorities’ assertions of equity often echo empty, bereft of corroboration. Joseph Bonneau, a cryptographer and researcher at Stanford’s Applied Crypto Group, demystified this domain at dotSecurity 2017, championing verifiable randomness as algorithmic accountability’s anchor. Formerly of Google and the Electronic Frontier Foundation, Joseph’s journey—Bitcoin’s blockchain to privacy’s precincts—culminates in constructs that compel proof from the capricious, from dice’s clatter to cryptographic commitments.
Joseph’s journey juxtaposed physical proofs’ pitfalls: lottery balls’ bias, dice’s deceit—transparency’s theater, yet tampering’s temptation. Cryptography’s counter: commitments’ covenant—hash’s hideaway, revealing randomness post-participation. Verifiable delay functions (VDFs) vex velocity: computations’ chronology, proofs’ promptness—adversaries’ acceleration averted. Joseph’s jewel: lottery’s ledger—participants’ pledges, commitments’ concatenation, hash’s harvest yielding winners’ wreath.
Applications amplify: H1B visas’ vagaries verified, elections’ audits authenticated—overbooked flights’ farewells fair. Joseph’s jibe: FIFA’s football fiascoes, fans’ fury—verifiability’s vindication. Blockchain’s boon: Bitcoin’s beacons, stock quotes’ surrogates—delay’s defense against traders’ tempo.
Challenges chime: VDFs’ verification velocity, parallelism’s peril—research’s realm ripe. Joseph’s rallying cry: demand documentation—dashlane’s draws, FIFA’s fixtures, governments’ gambits—cryptography’s capability calls.
Randomness’ Riddles and Physical Pitfalls
Joseph juxtaposed balls’ bias, dice’s deceit—commitments’ cure, delay’s deterrent.
Constructs’ Craft and Applications’ Ambit
Hash’s haven, VDFs’ vigil—lotteries’ ledger, visas’ verity. Blockchain’s bastion, stocks’ surrogate.
