V\u010faka memorandu o spolupr\u00e1ci medzi NEM Europe a Blockchain Slovakia sa NEM technol\u00f3gia dost\u00e1va do povedomia slovenskej blockchain komunity.<\/span><\/p>\n

NEM zaujal slovensk\u00fdch program\u00e1torov hlavne kv\u00f4li jednoduchosti v\u00fdvoja a vstavan\u00fdm funkci\u00e1m. To viedlo k <\/span>prv\u00e9mu NEM workshopu pre developerov v Bratislave<\/b>. Odohral sa 12. decembra v Progressbare, inovat\u00edvnej platforme pre t\u00fdch, ktor\u00ed sa zauj\u00edmaj\u00fa o hacking, 3D tla\u010d, programovanie, blockchain a in\u00e9 oblasti.<\/span><\/p>\n

Na workshope sa z\u00fa\u010dastnil \u0161peci\u00e1lny hos\u0165 Istv\u00e1n De\u00e1k, NEM Europe Solutions Architect z Viedne a cel\u00fdm workshopom V\u00e1s sprev\u00e1dzal Mat\u00fa\u0161 Rajsk\u00fd, NEM projekt koordin\u00e1tor pre Blockchain Slovakia.\u00a0<\/span><\/p>\n

Ako r\u00fdchlo sa d\u00e1 nau\u010di\u0165 programova\u0165 na blockchaine? Pod veden\u00edm Istv\u00e1na De\u00e1ka dok\u00e1zal t\u00edm 7 program\u00e1torov pou\u017e\u00edva\u0165 pokro\u010dil\u00e9 funkcie NEM Catapult blockchainu za 4 hodiny!<\/span><\/p>\n

Ako vyzer\u00e1 r\u00fdchlokurz programovania na NEM v praxi<\/b><\/p>\n

V prvom rade mus\u00edme zodpoveda\u0165 ot\u00e1zku, pre\u010do vlastne chceme pou\u017e\u00edva\u0165 blockchain. V \u00favode Istv\u00e1n prezentoval pr\u00edpadov\u00fa \u0161t\u00fadiu, v ktorej m\u00f4\u017ee blockchain zlep\u0161i\u0165 transparentnos\u0165 a minimalizova\u0165 nef\u00e9rov\u00e9 praktiky pri predaji l\u00edstkov na koncert.<\/span><\/p>\n

Nef\u00e9rov\u00e1 praktika pri predaji l\u00edstkov m\u00f4\u017ee by\u0165 skalpovanie: situ\u00e1cia, ke\u010f v\u00e4\u010d\u0161inu l\u00edstkov na koncert k\u00fapia fikt\u00edvne osoby pou\u017eit\u00edm botov. Potom sa tieto l\u00edstky objavia na druhotnom trhu za n\u00e1sobne vy\u0161\u0161ie ceny.<\/span><\/p>\n

Ako m\u00f4\u017ee NEM zabr\u00e1ni\u0165 skalpovaniu? Pou\u017eit\u00edm decentralizovan\u00fdch swapov. Proces je celkom jednoduch\u00fd:<\/span><\/p>\n

    \n
  1. Vytvor\u00edme Namespace a Mosaic, teda token, ktor\u00fd reprezentuje l\u00edstok na koncert.<\/span><\/li>\n
  2. Nastav\u00edme pravidl\u00e1, ktor\u00e9 umo\u017enia druhotn\u00fd predaj l\u00edstkov iba za ur\u010dit\u00fdch podmienok, napr\u00edklad iba v pr\u00edpade, \u017ee cena l\u00edstka nepresiahne ur\u010dit\u00fa hodnotu<\/span><\/li>\n
  3. Off-chain kontrakt potvrd\u00ed iba po\u017eiadavky, ktor\u00e9 sp\u013a\u0148aj\u00fa dan\u00e9 pravidl\u00e1.<\/span><\/li>\n<\/ol>\n
