M\u00f4\u017ee to znie\u0165 ako komplikovan\u00fd v\u00fdraz, ale nie je to ni\u010d v\u00e1\u017eneho, akon\u00e1hle to pochop\u00edte a uvediete do praxe, dokonca.

Tak\u017ee ... je to nie\u010do ako \u0165a\u017eba kryptomeny? Tak nejako. Je to v podstate alternat\u00edva k tradi\u010dnej \u0165a\u017ebe kryptomeny Proof of Work (PoW), ktor\u00fa pou\u017e\u00edvaj\u00fa mince ako Bitcoin (BTC). Trochu si to zapam\u00e4tajme.<\/p>\n\n\n\n

PoW je \u010fal\u0161\u00ed algoritmus<\/a>\u201eAlgoritmus\u201c znamen\u00e1 s\u00fabor krokov a met\u00f3d, ktor\u00e9 s\u00fa zostaven\u00e9 - s matematikou - na dosiahnutie konkr\u00e9tneho v\u00fdsledku alebo vyrie\u0161enie probl\u00e9mu.

\u010co je teda zl\u00e9 na PoS?<\/strong><\/h2>\n\n\n\n

Stru\u010dnou odpove\u010fou na to je zabezpe\u010denie siete. Tu sa trochu pozastav\u00edme, aby sme sa porozpr\u00e1vali o vidliciach. Viete, v\u00e4\u010d\u0161ina kryptomien je divok\u00fdch a bez ak\u00fdchko\u013evek autorsk\u00fdch pr\u00e1v, open-source a decentralizovan\u00e1.

Aby to bolo jasnej\u0161ie, Bitcoin v hotovosti<\/a> (BCH) je napr\u00edklad vidli\u010dka Bitcoin<\/a> (BTC). Maj\u00fa rovnak\u00fa hist\u00f3riu do roku 2017, ke\u010f sa BCH rozdelila in\u00fdm smerom a s nov\u00fdmi funkciami. Ale hej, obaja funguj\u00fa s PoW, nie s PoS. To znamen\u00e1, \u017ee ban\u00edci sa mali vtedy rozhodn\u00fa\u0165 medzi nimi dvoma.

To je v pr\u00edpade syst\u00e9mov PoS skuto\u010dne riziko. S PoW nem\u00e1 zmysel vytv\u00e1ra\u0165 nekone\u010dn\u00e9 vidlice, ale v PoS m\u00f4\u017eu by\u0165 pre podvodn\u00edkov ziskov\u00e9.

V\u00fdvoj\u00e1ri na tomto mo\u017enom probl\u00e9me pracuj\u00fa. Boli navrhnut\u00e9 tresty za zl\u00e9 spr\u00e1vanie, ako napr\u00edklad seknutie alebo konfi\u0161k\u00e1cia kolov podvodn\u00edkov. Je to v\u0161ak nedokon\u010den\u00e1 pr\u00e1ca.

Pravdepodobne hlavn\u00fdm probl\u00e9mom, ktor\u00fd m\u00f4\u017ee vyvola\u0165 opr\u00e1vnen\u00e9 obavy v s\u00favislosti s t\u00fdmto syst\u00e9mom, je environment\u00e1lny faktor.

Z perspekt\u00edvy je to viac ako v krajin\u00e1ch ako F\u00ednsko, \u0160vaj\u010diarsko a Portugalsko.<\/p>\n\n\n\n
