Rekli smo vec da je blockchain baza podataka.Blockchain je sastavljen od blokova od po 1mb i ti podaci su me\u0111usobno kriptovani,odnosno zaklju\u010dani.<\/p>\n
Rekli smo da se baza uve\u0107a svakih 10 minuta za jedan novi blok,odnosno 1 mb*.<\/p>\n
To uve\u0107anje baze vr\u0161e ljudi koji imaju ra\u010dunare i specijalizovane ma\u0161ine priklju\u010dene na blockchain.To su rudari,a nazivaju se rudarima jer danono\u0107no rade na blockchainu.<\/p>\n
Ne\u0107emo ulaziti u detalje oko rudara ali bitno je da znate da rudari bez obzira \u0161to imaju jake ma\u0161ine mogu samo da upisuju podatke ali ne da ih I bri\u0161u.Oni za ovaj posao budu nagra\u0111eni novim bitcoinima.<\/p>\n
Motiv da budete rudar je jednostavan ,imate financijsku korist od toga.Upro\u0161\u0107eno to zna\u010di da mi \u201cobi\u010dni\u201d korisnici pla\u0107amo rudarima da nas \u010duvaju i rade za nas po bitcoin pravilima.<\/p>\n
\u0160to je vi\u0161e rudara priklju\u010deno na blockchain to je on sigurniji.\u0160to je veci broj korisnika,to je vrijedniji blockchain,pa taj blockchain privla\u010di i vi\u0161e rudara.I tako zajednica raste.<\/p>\n
Kad je 2009 godine pu\u0161ten Bitcoin blockchain u opticaj bio je velik 1 mb i imao je jedan blok.Za 10 minuta dodao se novi blok i blockchain je narastao na 2 mb,sledeci 10 minuta dodao se 3 blok i blockchain je porastao na 3 mb.<\/p>\n
I tako je nastao bitcoin blockchain ,odnosno nastali su blokovi u lancu.Nastali su blokovi zakljucani jedan za drugoga.<\/p>\n
Treba napomenuti da ti prvi blokovi prakti\u010dno nisu imali puno podataka pa 1 mb nije bio ni popunjen.<\/p>\n
Danas 2018 godine,a 9 godina kasnije Bitcoin blockchain je velik oko 190 gb.<\/p>\n
Spomenuli smo da se Bitcoini nalaze unutar Blockchaina i njihov broj je jasno definisan i javan.Ukupan broj bitcoina \u0107e biti 21 milion,a ve\u0107 danas u opticaju se nalazi 81%.<\/p>\n
To zna\u010di da se trenutno u opticaju nalazi oko 17 miliona bitcoina,a preostalih 20% bitcoina \u0107e se pojaviti u blockchainu u narednim godinama.<\/p>\n
Napomenu\u0107emo da se novoupisani bitcoin dodjeljuju rudarima kao nagrada za upisivanje novih blokova i transakcija.<\/p>\n
Tako\u0111e ,na taj na\u010din se pla\u0107a i sigurnost same mre\u017ee.Rudari takode dobijaju i mali procenat od svih transakcija,tako da ce biti pla\u0107ani za svoj rad i kad se svi bitcoini puste u bazu,puste u blockchain.<\/p>\n
