On-chain Korean blockchain class recap by Pablock organizer, July 2018. Date, Seoul venue, full attendee roster, airdrop record.
Key Facts
Description
An on-chain class recap deployed July 2018 by the organizer of a Pablock community blockchain workshop in Seoul. Calling the no-argument getter at selector 0x8a4d5a67 returns a Solidity string whose body is itself a hex-encoded UTF-8 byte sequence (an extra encoding layer the author used to avoid any non-ASCII bytes in the source). After decoding, the contract records: the class title (Easiest blockchain class in the world; Pablock), the date and time (Thursday, July 12, 2018, 7:30 PM), the venue (2F The Air, 14-gil 7 Bangbaecheon-ro, Seocho-gu, Seoul), the full roster of 30 attendees by name, and the sponsorship credits (Inblock, The Air, Pablo Plus Chain). It also records that every attendee received an airdrop of 30,000 Pablo Plus tokens. The organizer used Ethereum as a permanent attendance ledger for a single in-person meetup.
