Blockchain \u0219i mai mult blockchain! Acesta este \u00een prezent un termen comun, aproape o mod\u0103 \u00een sferele corporative. Toat\u0103 lumea \u00ee\u0219i dore\u0219te ceva cu blockchain, chiar dac\u0103 nu \u0219tie exact ce este un \u201eblockchain\u201d. Ceva despre criptomonede, nu? Ceva ca un nou lucru super-tehnic, nu ...?<\/p>\n\n\n\n

Nu exact, prietene. Deci, putem \u00eencepe s\u0103 afirm\u0103m ce NU este un blockchain \u0219i pentru ce NU este:<\/p>\n\n\n\n

* Blockchain nu este o criptomoned\u0103.
* Blockchain nu este o platform\u0103 de investi\u021bii.
* Blockchain nu este cea mai mare platform\u0103 open-source.
* Blockchain nu poate fi un sistem distribuit.
* Blockchain nu poate fi un descentralizat<\/em> sistem.
* Blockchain-ul nu este magic.
* Blockchain nu v\u0103 poate rezolva toate problemele.
* Blockchain nu poate cre\u0219te c\u00e2\u0219tigurile \u00een niciun fel.
 <\/strong><\/p>\n\n\n\n

Toate clare? Apoi, putem \u00eencepe a invata<\/a> ce este cu adev\u0103rat un \u201eblockchain\u201d \u0219i care este scopul s\u0103u \u00een univers.<\/p>\n\n\n\n

Un blockchain este ...<\/strong><\/h2>\n\n\n\n

Acest lucru nu este altceva dec\u00e2t un registru contabil \u00eentr-o versiune criptat\u0103 digital.<\/strong> Sun\u0103 plictisitor? Ei bine, este un pic plictisitor, ca s\u0103 fiu sincer. Unde este magia acolo? De ce toat\u0103 lumea este at\u00e2t de \u00eenc\u00e2ntat\u0103? \u0218i de ce chestia asta are ceva de f\u0103cut cu criptomonede?<\/a> S\u0103 ne explic\u0103m.<\/p>\n\n\n\n

\u00cen urm\u0103 cu doisprezece ani, persoana (sau grupul de oameni) cunoscut sub numele de Satoshi Nakamoto \u00eencerca s\u0103 rezolve problema dublei cheltuieli cu numerarul digital \u00eentr-un mod f\u0103r\u0103 \u00eencredere. O.K! Putem \u00eencetini pu\u021bin. Cheltuielile duble sunt, practic, cheltui\u021bi aceia\u0219i bani digitali de mai multe ori (a\u0219a cum ar trebui s\u0103 fie). \u0218tii, po\u021bi copia \u0219i lipi aproape tot de pe Internet, de ce nu banii?<\/p>\n\n\n\n

Pentru a evita acest tip de comportament, am avut \u00eencredere \u00een institu\u021biile centralizate, cum ar fi b\u0103ncile \u0219i guvernele. Odat\u0103 ce a\u021bi trimis un transfer bancar electronic, sistemul b\u0103ncii scade ace\u0219ti bani din contul dvs. Dac\u0103 nu ar fi acolo, probabil c\u0103 oamenii ar cheltui aceia\u0219i bani de mai multe ori. \u0218i c\u0103 e ca un jaf.<\/p>\n\n\n\n

Asa de, Satoshi se g\u00e2ndea \u00eentr-un sistem automat pentru a \u00eenlocui aceste institu\u021bii centralizate <\/strong>\u0219i face posibil\u0103 ob\u021binerea de numerar digital f\u0103r\u0103 problema dublei cheltuieli \u00een acela\u0219i timp. El \/ ea \/ ea a luat apoi un fel de baz\u0103 de date experimental\u0103 criptografic\u0103 (criptat\u0103) creat\u0103 \u00een anii 70 \u0219i a amestecat-o cu alte elemente tehnice pentru a crea prima moned\u0103 digital\u0103 descentralizat\u0103 f\u0103r\u0103 o problem\u0103 de cheltuieli duble. \u0218i Bitcoin s-a n\u0103scut \u00een 2009!<\/p>\n\n\n\n

Aceast\u0103 baz\u0103 de date criptografic\u0103 experimental\u0103 este faimosul blockchain, \u00een ciuda faptului c\u0103 nimeni nu o \u0219tia atunci. Nici m\u0103car Satoshi: a venit numele dup\u0103 Bitcoin<\/a>. De ce nu \u201ebaza de date cripto\u201d sau ceva de genul acesta, \u00een loc de \u201eblockchain\u201d? Ei bine, este pentru c\u0103 baza de date este de fapt ... un lan\u021b de blocuri, a\u0219a cum pare. Blocuri digitale.<\/p>\n\n\n\n

Cum func\u021bioneaz\u0103 blocurile?<\/strong><\/h2>\n\n\n\n

Fiecare \u201ebloc\u201d este un mic container de date<\/strong> (tranzac\u021bii monetare, \u00eentr-un caz de criptomoned\u0103), \u00eenl\u0103n\u021buite la toate celelalte (trecut \u0219i viitor) cu ceva numit \u201ehash\u201d. Acestea sunt rezultatul criptat de la trecerea datelor printr-un algoritm complex. Ceva de genul acesta (dac\u0103 folosim Algoritm SHA256<\/a>):<\/p>\n\n\n\n

* Date ini\u021biale: a\u021bi transferat 1 BTC c\u0103tre Mike.
* Date hash: 710DAEB54021CCD83046E4FA16106E4DC10E5D617E4C28F61CE29C29CFAE823E<\/p>\n\n\n\n

Fiecare hash reprezint\u0103 o identitate unic\u0103 pentru fiecare tranzac\u021bie \u0219i fiecare bloc (un grup de tranzac\u021bii) existente. Toate acele identit\u0103\u021bi se \u00eembin\u0103 matematic mai t\u00e2rziu \u00eentre ele, \u201e\u00eenl\u0103n\u021buindu-se\u201d astfel. Deci, dac\u0103 cineva \u00eencearc\u0103 s\u0103 tri\u0219eze, hash-ul tranzac\u021biei sale (identitatea unic\u0103) se va schimba; iar dac\u0103 se schimb\u0103, va fi descatenat \u0219i va deveni automat invalid.<\/p>\n\n\n\n

De exemplu, s\u0103 ne amintim datele noastre ini\u021biale (a\u021bi transferat 1 BTC c\u0103tre Mike). Dac\u0103 schimb\u0103m chiar \u0219i un mic personaj acolo, hash-ul se va schimba radical \u0219i:<\/p>\n\n\n\n

Tranzac\u021bia nu mai este valabil\u0103 \u0219i tu, s\u0103rac muritor, nu po\u021bi \u00een\u0219ela sistemul blockchain. Chiar dac\u0103 autorit\u0103\u021bile nu supravegheaz\u0103. Dar acum, s\u0103 simul\u0103m \u201efuzionarea\u201d \u00eentre tranzac\u021bii. S\u0103 presupunem c\u0103 acele hash-uri sunt \u00eentr-adev\u0103r valabile \u0219i reprezint\u0103 identit\u0103\u021bile a dou\u0103 blocuri diferite. Cum se leag\u0103 \u00eentre ei? Des\u0103v\u00e2r\u0219indu-se \u00eempreun\u0103, desigur.<\/strong> Ca aceasta:<\/p>\n\n\n\n

Si asta e! Dac\u0103 dori\u021bi s\u0103 schimba\u021bi ceva \u0219i s\u0103 \u00eel face\u021bi valabil, trebuie mai \u00eent\u00e2i s\u0103 descifra\u021bi \u0219i s\u0103 schimba\u021bi fiecare bloc existent. Mult succes cu asta.<\/p>\n\n\n\n

Un blockchain nu func\u021bioneaz\u0103 singur<\/strong><\/h2>\n\n\n\n

\u00cen ciuda matematicii, acel registru sofisticat nu poate func\u021biona de la sine. Are nevoie de celelalte elemente pe care Satoshi i le-a ad\u0103ugat: o re\u021bea distribuit\u0103 de noduri (\u0219i persoane), algoritmul men\u021bionat anterior pentru a cripta tranzac\u021biile \u0219i a stabili regulile pentru validatori, tranzac\u021biile de cheltuit sau \u201emonede\u201d \u0219i cheile criptografice private \u0219i publice. S\u0103 verific\u0103m repede unul c\u00e2te unul.<\/p>\n\n\n\n

Nu sunt b\u0103nci sau guverne, dar cineva ar trebui s\u0103 verifice tranzac\u021biile \u00eentr-un fel. \u0218i, pentru sistemele descentralizate (ca majoritatea criptomonedelor), aceasta ar fi o re\u021bea distribuit\u0103 conform\u0103 multor oameni din \u00eentreaga lume \u0219i computerelor \u0219i echipamentelor (nodurilor) lor. Mai ales ultimele.<\/p>\n\n\n\n

Lucrul este, fiecare membru al re\u021belei (cunoscut sub numele de miner sau validator<\/a>) are o copie a \u00eentregului blockchain \u00een hardware-ul lor<\/strong>, iar software-ul lor special sau echipamentele miniere sunt \u00eens\u0103rcinate cu verificarea \u0219i p\u0103strarea eviden\u021bei fiec\u0103rei tranzac\u021bii noi \u0219i cu monede noi; urm\u00e2nd regulile matematice stabilite de algoritmul sistemului. Rezultatul ar trebui s\u0103 fie \u00eentotdeauna acela\u0219i pentru majoritatea validatorilor, \u00een caz contrar, tranzac\u021bia sau blocul vor fi nevalide.<\/p>\n\n\n\n

Putem defini un algoritm ca un set de pa\u0219i \u0219i metode care sunt construite - cu matematic\u0103 - pentru a ob\u021bine un rezultat specific sau pentru a rezolva o problem\u0103. Exist\u0103 o mul\u021bime de algoritmi acolo \u0219i nu to\u021bi lucreaz\u0103 pentru a construi un blockchain.

Nici fiecare sistem de criptomonede sau blockchain nu folose\u0219te acela\u0219i algoritm.<\/strong> Bitcoin, de exemplu<\/a>, folose\u0219te SHA256 (cel pe care l-am folosit \u00eenainte), dar Ethereum folose\u0219te Ethash \u0219i Zcash folose\u0219te Equihash.

Acestea sunt chei matematice care func\u021bioneaz\u0103 ca adrese pentru a trimite \u0219i primi fonduri \u00een interiorul unui blockchain.

Dup\u0103 cum am spus la \u00eenceput, este posibil ca un blockchain s\u0103 nu fie distribuit \u0219i s\u0103 nu fie descentralizat. La urma urmei, este doar un registru criptografic, iar celelalte elemente care func\u021bioneaz\u0103 cu acesta se pot schimba \u00een func\u021bie de nevoile creatorilor lor.<\/p>\n\n\n\n

Satoshi Nakamoto a fost prima persoan\u0103 care l-a folosit cu Bitcoin, dar codul surs\u0103<\/a> c\u0103ci acest tip de registru este deschis publicului. Poate fi copiat, lipit, modificat \u0219i chiar v\u00e2ndut. Deci, o mul\u021bime de oameni (\u0219i \u00eentreprinderi) din \u00eentreaga lume au \u00eencercat aceast\u0103 tehnologie pentru propriile utiliz\u0103ri, chiar \u0219i dincolo de criptomonede. B\u0103ncile nu sunt excluse: le place s\u0103 foloseasc\u0103 blockchain-uri pentru a construi noi platforme de plat\u0103. \u0218i, dup\u0103 cum v\u0103 pute\u021bi imagina, acestea nu sunt descentralizate, ci controlate \u00een totalitate de re\u021beaua institu\u021bional\u0103.<\/p>\n\n\n\n

Uneori, blockchain-urile nu func\u021bioneaz\u0103 cu re\u021bele distribuite, ci doar cu re\u021bele interne controlate<\/strong>. Acest tip de platform\u0103 are nevoie de permisiunile utilizatorilor de la creatori, a\u0219a c\u0103 sunt numite blockchain-uri \u201epermise\u201d sau private. Pe de alt\u0103 parte, criptomonedele \u0219i platformele precum Bitcoin func\u021bioneaz\u0103 cu re\u021bele descentralizate. Asta le face \u201ef\u0103r\u0103 permisiuni\u201d sau publice.<\/p>\n\n\n\n
