\nHanyecz a intrat din nou \u00een aten\u0163ia presei \u015fi de data aceasta tot pentru c\u0103 a cump\u0103rat dou\u0103 pizza. De data aceasta el a vrut s\u0103 testeze re\u0163eaua lighting network care func\u0163ioneaz\u0103 pe blockchain-ul de bitcoin, implementat\u0103 pentru a cre\u015fte viteza tranzac\u0163iilor. Astfel el a pl\u0103tit 0.00649 bitcoini pentru 2 pizza (67 de dolari), iar tranzac\u0163ia l-a costat 6 cen\u0163i.<\/p>\n
\n“Am vrut s\u0103 le demonstrez oamenilor c\u0103 \u00eenc\u0103 po\u0163i cump\u0103ra pizza cu bitcoin. Dar dac\u0103 dai 50 de dolari pe pizza \u015fi ai o tax\u0103 de tranzac\u0163ionare de 100 de dolari atunci nu func\u0163ioneaz\u0103. Ideea este c\u0103 prin lighting network tranzac\u0163iilor pot fi instante cu aceea\u015fi securitate a blockchain-ului \u015fi taxele sunt minime”, a declart Hanyecz pentru Bloomberg. <\/p>\n
\nBlockchainul (lan\u0163ul de blocuri) este compus din mai multe blocuri care con\u0163in colec\u0163ii de tranzac\u0163ii organizate \u00een buc\u0103\u0163i secven\u0163iale. Pentru ca o tranzac\u0163ie s\u0103 devin\u0103 oficial\u0103, ceilal\u0163i juc\u0103tori (minerii) trebuie s\u0103 efectueze proceduri computa\u0163ionale (s\u0103 pun\u0103 calculatoarele la treab\u0103 s\u0103 rezolve anumi\u0163i algoritmi) pentru a putea plasa acea tranzac\u0163ie \u00een bloc, un proces care dureaz\u0103 cam 10 minute. Aproximativ 2.000 de tranzac\u0163ii se pot stoca \u00eentr-un singur bloc, astfel apar \u00eent\u00e2rzieri. Pentru c\u0103 spa\u0163iul dintr-un bloc este limitat, utilizatorii care fac o tranzac\u0163ie ata\u015feaz\u0103 o mic\u0103 tax\u0103, pentru a motiva minerii s\u0103 includ\u0103 tranzac\u0163ia \u00een bloc \u00eenaintea altora. Aceste taxe de tranzac\u0163ionare pot fi de c\u00e2\u0163iva de dolari sau mai mult, iar taxa este aceea\u015fi, indiferent dac\u0103 faci o tranzac\u0163ie de 5 bitcoini sau 10.000 de bitcoini. \u201eDac\u0103 se implementeaz\u0103 lighting network anul acesta, atunci vor fi mari probleme pentru procesatorii de pl\u0103\u0163i. \u00ce\u0163i voi putea trimite bani \u00een mai pu\u0163in de o secund\u0103, la un cost minimal. Po\u0163i s\u0103 trimi\u0163i 100 de miliarde de dolari ap\u0103s\u00e2nd un buton\u201d, spune fondatorul Netopia.<\/p>\n
\nIdeea din spatele lighting network este c\u0103 majoritatea pl\u0103\u0163ilor nu trebuie \u00eenregistrate \u00een registrul bitcoin. \u00cen schimb, pl\u0103\u0163ile pot avea loc \u00een canale private \u00eentre utilizatori. Astfel, lighting network \u00eencearc\u0103 s\u0103 deplaseze multe tranzac\u0163ii \u00een canalele private. Astfel \u00eenc\u00e2t atunci c\u00e2nd cumperi o cafea cu bitcoin, acea tranzac\u0163ie s\u0103 nu mai fie stocat\u0103 \u00een blockchain, ci \u00een canalul privat care este ata\u015fat blockchainului.<\/p>\n
