Projekt Wormhole DeFi<\/h2>\n

\u010cerv\u00ed d\u00edra je most mezi Solanou a ostatn\u00edmi blockchainy. Bylo ukradeno asi 120 000 ether\u016f, co\u017e z n\u011bj d\u011bl\u00e1 druh\u00fd nejv\u011bt\u0161\u00ed hack DeFi. Celkov\u00e1 aktiva \u010derv\u00ed d\u00edry p\u0159esahuj\u00ed 1 miliardu dolar\u016f. Podporuje tak\u00e9 asi \u0161est blockchain\u016f v\u010detn\u011b Polygonu, Binance Smart Chain, Avalanche, Etherea<\/a>, Terry a Solany.<\/p>\n

B\u011bhem hackersk\u00e9ho \u00fatoku byl ovlivn\u011bn pouze syst\u00e9m wETH. Ostatn\u00ed \u017eetony jsou st\u00e1le neporu\u0161en\u00e9. Wormhole funguje tak, \u017ee kdy\u017e obchodn\u00edk p\u0159ev\u00e1d\u00ed aktiva z jednoho blockchainu<\/a>do druh\u00e9ho, dojde k uzam\u010den\u00ed transakce.

Po \u00fatoku spole\u010dnost Wormhole uvedla, \u017ee zranitelnost, kter\u00e1 vedla k \u00fatoku, byla opravena. S\u00ed\u0165 tak\u00e9 p\u0159idala ETH, aby zajistila, \u017ee wETH bude neust\u00e1le podporov\u00e1n na z\u00e1klad\u011b principu one-to-one.

Po \u00fatoku se cena sn\u00ed\u017eila o 14,36 %.<\/p>\n

Je zabezpe\u010den\u00ed DeFi dobr\u00e9?<\/h2>\n

Spoluzakladatel spole\u010dnosti Bloomberg Tom Robinson po \u00fatoku uvedl, \u017ee zabezpe\u010den\u00ed slu\u017eeb DeFi nedos\u00e1hlo \u00farovn\u011b, kdy by bylo mo\u017en\u00e9 ukl\u00e1dat obrovsk\u00e9 mno\u017estv\u00ed dat<\/a>.

V oblasti DeFi je bohu\u017eel druh\u00e1 nejv\u011bt\u0161\u00ed. N\u011bkter\u00e9 z ob\u011bt\u00ed se pokusily hackera p\u0159\u00edmo kontaktovat. Zde je p\u0159\u00edklad zpr\u00e1vy zaslan\u00e9 dan\u00e9 osob\u011b: „P\u0159i va\u0161em \u00fatoku jsem p\u0159i\u0161el o 100 000 dolar\u016f. Jsem zdravotn\u00ed sestra.

\u00datoky, ke kter\u00fdm do\u0161lo v minulosti, v\u010detn\u011b toho z ledna lo\u0148sk\u00e9ho roku, kdy se ztratilo 80 milion\u016f dolar\u016f minc\u00ed Binance, jsou znepokojiv\u00e9.

To vyvol\u00e1v\u00e1 obavy ve\u0159ejnosti o bezpe\u010dnost projekt\u016f DeFi. Kdy\u017e se pod\u00edv\u00e1te na projekty DeFi, vypadaj\u00ed l\u00e1kav\u011b.

M\u00edsto toho byste m\u011bli zv\u00e1\u017eit jeho zabezpe\u010den\u00ed a ochranu.<\/p>\n

Tento probl\u00e9m zp\u016fsobuje, \u017ee je zraniteln\u00fd v\u016f\u010di hacker\u016fm. V sou\u010dasn\u00e9 dob\u011b existuje n\u011bkolik projekt\u016f DeFi, ze kter\u00fdch si m\u016f\u017eete vybrat. Proto byste jako investor m\u011bli investovat jen do t\u011bch, kter\u00e9 pova\u017eujete za spolehliv\u00e9. V sou\u010dasn\u00e9 dob\u011b bylo z projekt\u016f DeFi kv\u016fli jeho zranitelnosti odcizeno p\u0159ibli\u017en\u011b 2,2 miliardy.<\/p>\n

Dr\u017eitel\u00e9 kryptom\u011bn obvykle nep\u016fsob\u00ed v jednom blockchainov\u00e9m ekosyst\u00e9mu. Z tohoto d\u016fvodu v\u00fdvoj\u00e1\u0159i vyvinuli mezi\u0159et\u011bzcov\u00e9 mosty. C\u00edlem je umo\u017enit u\u017eivatel\u016fm pos\u00edlat kryptom\u011bny z jednoho \u0159et\u011bzce do druh\u00e9ho.<\/p>\n

Wormhole umo\u017e\u0148uje u\u017eivatel\u016fm p\u0159esouvat sv\u00e9 NFT a tokeny mezi Ethereem a Solanou<\/a>. Po \u00fatoku se s\u00ed\u0165 stala offline. V\u00fdvoj\u00e1\u0159i uvedli, \u017ee b\u011bhem tohoto obdob\u00ed byla slu\u017eba odstavena z d\u016fvodu \u00fadr\u017eby.<\/p>\n

Wormhole funguje tak, \u017ee m\u00e1 dva chytr\u00e9 kontrakty.
