Bitcoin

Bitcoin (₿) ndi ndalama za digito zomwe zitha kusamutsidwa pa intaneti ya anzawo ndi anzawo. [7] Zochita za Bitcoin zimatsimikiziridwa ndi ma netiweki kudzera pa cryptography ndikujambulidwa mu buku lofalitsidwa ndi anthu lotchedwa blockchain. The cryptocurrency anatulukira mu 2008 ndi munthu osadziwika kapena gulu la anthu ntchito dzina Satoshi Nakamoto.[10] Ndalamayi idayamba kugwiritsidwa ntchito mu 2009[11] pomwe kukhazikitsidwa kwake kudatulutsidwa ngati pulogalamu yotseguka.

Bitcoins amapangidwa ngati mphotho ya njira yotchedwa migodi. Atha kusinthidwa ndi ndalama zina, zogulitsa, ndi ntchito zina. Bitcoin yadzudzulidwa chifukwa chogwiritsidwa ntchito pochita zinthu zoletsedwa, kuchuluka kwa magetsi (ndipo motero mpweya wa carbon) womwe umagwiritsidwa ntchito ndi migodi, kusinthasintha kwamtengo wapatali, ndi kuba kwa kusinthanitsa. Osunga ndalama ena ndi akatswiri azachuma amaziwonetsa ngati zongopeka nthawi zosiyanasiyana.

Bitcoin, wakhala akufotokozedwa ngati kuwira chuma kuwira ndi osachepera asanu ndi atatu Nobel Memorial Prize mu Economic Sciences.[12] Atolankhani, akatswiri azachuma, osunga ndalama, ndi banki yayikulu ya Estonia anena kuti bitcoin ndi dongosolo la Ponzi. [13] [14] [15] [16]

Mawu akuti bitcoin adatanthauzidwa mu pepala loyera lofalitsidwa pa 31 October 2008. [4] [17] Ndi kuphatikiza kwa mawu akuti bit ndi coin.[18] Palibe yunifolomu msonkhano wa bitcoin capitalization alipo; Magwero ena amagwiritsa ntchito Bitcoin, capitalized, kunena zaukadaulo ndi maukonde ndi bitcoin, lowercase, kwa unit of account.[19] The Wall Street Journal, [20] The Chronicle of Higher Education, [21] ndi Oxford English Dictionary [18] amalimbikitsa kugwiritsa ntchito bitcoin zilembo zing'onozing'ono nthawi zonse.

Maboma angapo am'deralo ndi amayiko akugwiritsa ntchito Bitcoin mwanjira ina, ndi mayiko awiri, El Salvador ndi Central African Republic, akutenga ngati njira yovomerezeka.

Mayunitsi ndi kugawanika

Chigawo cha akaunti ya bitcoin system ndi bitcoin. Ndalama zoyimira bitcoin ndi BTC[a] ndi XBT.[b][25]: 2  Khalidwe lake la Unicode ndi ₿.[1] bitcoin imodzi imagawidwa ndi malo asanu ndi atatu. [6]: ch. 5  Mayunitsi a tinthu tating'ono ta bitcoin ndi millibitcoin (mBTC), yofanana ndi 1⁄1000 bitcoin, ndi satoshi (sat), lomwe ndi gawo laling'ono kwambiri, ndipo limatchulidwa polemekeza Mlengi wa bitcoin, kuimira 1⁄100000000 (zana. miliyoni) bitcoin [2] 100,000 satoshis ndi mBTC imodzi.[26]

Blockchain

Mapangidwe a data a midadada mu leja.

Chiwerengero chazomwe zimachitika pa bitcoin pamwezi, chiwembu cha semilogarithmic[27]

Chiwerengero cha zotsatira zomwe sizinagwiritsidwe ntchito[28] The bitcoin blockchain ndi buku la anthu lomwe limalemba zochitika za bitcoin.[29] Imakhazikitsidwa ngati midadada yotsatizana, chipika chilichonse chokhala ndi ma cryptographic hashi ya block yapitayo mpaka ku block ya genesis[c] mu unyolo. Maukonde olumikizirana omwe amayendetsa mapulogalamu a bitcoin amasunga blockchain.[30]: 215–219  Kusinthana kwa fomu yolipira X imatumiza ma bitcoins a Y kwa wolipidwa Z amawulutsidwa ku netiweki iyi pogwiritsa ntchito mapulogalamu omwe amapezeka mosavuta.

Ma node a netiweki amatha kutsimikizira zomwe zachitika, kuziwonjezera pamakope awo, kenako ndikuwulutsa zowonjezera zaleji ku ma node ena. Kuti tikwaniritse kutsimikizira paokha unyolo wa umwini aliyense maukonde mfundo amasunga buku lake la blockchain.[31] Pazigawo zosiyanasiyana za nthawi yofikira mphindi iliyonse ya 10, gulu latsopano la zochitika zovomerezeka, lotchedwa chipika, limapangidwa, likuwonjezeredwa ku blockchain, ndipo limafalitsidwa mwamsanga ku ma node onse, osafuna kuyang'anira pakati. Izi zimalola mapulogalamu a bitcoin kuti adziwe nthawi yomwe bitcoin inayake idagwiritsidwa ntchito, zomwe zimafunika kupewa kuwononga kawiri. A ledger ochiritsira amalemba kusamutsidwa kwa mabilu enieni kapena zolemba zamalonda zomwe zilipo popanda izo, koma blockchain ndi malo okhawo omwe bitcoins anganene kuti alipo mu mawonekedwe a zotuluka zosagwiritsidwa ntchito zamalonda.[6]: ch. 5

midadada aliyense, maadiresi onse ndi zochitika mkati midadada akhoza kufufuzidwa pogwiritsa ntchito blockchain wofufuza.

Zochita Onaninso: Bitcoin network Zochita zimatanthauzidwa pogwiritsa ntchito chilankhulo cha Forth-like scripting.[6]: ch. 5  Zochita zimakhala ndi cholowa chimodzi kapena zingapo komanso zotulutsa chimodzi kapena zingapo. Wogwiritsa ntchito akatumiza ma bitcoins, wogwiritsa ntchito amasankha adilesi iliyonse ndi kuchuluka kwa bitcoin yomwe imatumizidwa ku adilesiyo pazotulutsa. Pofuna kupewa kuwononga kawiri, cholowetsa chilichonse chiyenera kutchula zomwe sizinagwiritsidwe ntchito kale mu blockchain.[32] Kugwiritsiridwa ntchito kwa zolowetsa zambiri kumagwirizana ndi kugwiritsa ntchito ndalama zambiri pochita malonda. Popeza kugulitsa kumatha kukhala ndi zotuluka zingapo, ogwiritsa ntchito amatha kutumiza ma bitcoins kwa olandila angapo pakuchita kumodzi. Monga momwe zimakhalira ndi ndalama, kuchuluka kwa zolowa (ndalama zomwe zimagwiritsidwa ntchito polipira) zitha kupitilira zomwe zaperekedwa. Zikatero, kutulutsa kowonjezera kumagwiritsidwa ntchito, kubwezera kusintha kwa wolipira. [32] Ma satoshis aliwonse omwe sanawerengedwe pazotulukapo amakhala ndalama zogulira.[32]

Ngakhale ndalama zolipirira ndi zosankha, ogwira ntchito ku migodi amatha kusankha zomwe akuyenera kukonza ndikuyika patsogolo zomwe zimalipira ndalama zambiri.[32] Ogwira ntchito m'migodi angasankhe zochita kutengera ndalama zomwe amalipira potengera kukula kwawo kosungira, osati kuchuluka kwa ndalama zomwe amalipira ngati chindapusa. Ndalamazi zimayesedwa mu satoshis pa baiti (sat/b). Kukula kwa zochitika kumatengera kuchuluka kwa zomwe zalowetsedwa popanga malondawo, komanso kuchuluka kwa zomwe zatuluka.[6]: ch. 8

Ma midadada mu blockchain poyamba anali ochepa 32 megabytes kukula. Kuchuluka kwa chipika cha megabyte imodzi kunayambitsidwa ndi Satoshi Nakamoto mu 2010. Pambuyo pake malire a kukula kwa chipika cha megabyte imodzi adayambitsa mavuto pakukonza zinthu, monga kuonjezera ndalama zogulira ndi kuchedwa kukonza zochitika. [33] Andreas Antonopoulos wanena kuti Lightning Network ndi njira yothetsera makulitsidwe ndipo amatchula mphezi ngati njira yachiwiri yosanjikiza. [6]: ch. 8

Unyolo wosavuta wa umwini monga momwe zikuwonetsedwera mu bitcoin whitepaper.[4] M'menemo, kugulitsa kumatha kukhala ndi zolowetsa zambiri komanso zotulutsa zambiri.[32] Mu blockchain, ma bitcoins amalembetsedwa ku ma adilesi a bitcoin. Kupanga adilesi ya bitcoin sikungofunika china koma kusankha kiyi yachinsinsi yachinsinsi ndikuyika adilesi yofananira. Kuwerengera uku kutha kuchitika pakagawanika sekondi. Koma m'malo mwake, kupanga kiyi yachinsinsi ya adilesi yomwe yapatsidwa bitcoin, ndizosatheka.[6]: ch. 4  Ogwiritsa amatha kuuza ena kapena kuyika pagulu adilesi ya bitcoin popanda kusokoneza chinsinsi chake chachinsinsi. Kuphatikiza apo, kuchuluka kwa makiyi achinsinsi ovomerezeka ndi akulu kwambiri kotero kuti ndizokayikitsa kuti wina angawerenge makiyi omwe akugwiritsidwa ntchito kale ndipo ali ndi ndalama. Kuchuluka kwa makiyi achinsinsi ovomerezeka kumapangitsa kuti zikhale zosatheka kuti mphamvu zankhanza zitha kugwiritsidwa ntchito kusokoneza makiyi achinsinsi. Kuti athe kugwiritsa ntchito ma bitcoins awo, eni ake ayenera kudziwa chinsinsi chofananira chachinsinsi ndikusaina malondawo [d] Maukonde amatsimikizira siginecha pogwiritsa ntchito kiyi yapagulu; kiyi yachinsinsi sinaululidwe.[6]: ch. 5

Ngati chinsinsi chachinsinsi chatayika, maukonde a bitcoin sadzazindikira umboni wina uliwonse wa umwini;[30] ndalamazo zimakhala zosagwiritsidwa ntchito, ndipo zimatayika. Mwachitsanzo, mu 2013 wogwiritsa ntchito wina ananena kuti anataya ma bitcoins 7,500, okwana madola 7.5 miliyoni panthawiyo, pamene mwangozi anataya hard drive yomwe munali kiyi

Migodi Onaninso: Bitcoin network § Migodi

Ogwira ntchito m'migodi akale a bitcoin ankagwiritsa ntchito ma GPU pamigodi, chifukwa anali oyenererana ndi umboni wa ntchito kuposa ma CPU. [41]

Pambuyo pake ankachita masewera amakumba ma bitcoins ndi tchipisi tapadera za FPGA ndi ASIC. Ma chips omwe ali pachithunzichi atha kutha chifukwa chazovuta.

Masiku ano, makampani amigodi a bitcoin amapereka maofesi ku nyumba ndikugwira ntchito zambiri za hardware zamigodi zomwe zimagwira ntchito kwambiri. [42]

Semi-log chiwembu chazovuta zamigodi [e][28] Migodi ndi ntchito yosunga zolembedwa zomwe zimachitika pogwiritsa ntchito mphamvu yakukonza makompyuta. [f] Ogwira ntchito ku migodi amasunga blockchain kukhala yokhazikika, yokwanira, komanso yosasinthika pogawa mobwerezabwereza zomwe zangochitika kumene ku block, zomwe zimawulutsidwa ku netiweki ndikutsimikiziridwa ndi wolandira. mfundo.[29] Chida chilichonse chimakhala ndi SHA-256 cryptographic hash ya chipika chapitacho, [29] potero amachilumikiza ku chipika chapitacho ndikupatsa blockchain dzina lake.[6]: ch. 7 [29]

Kuti avomerezedwe ndi maukonde ena onse, chipika chatsopano chiyenera kukhala ndi umboni wa ntchito (PoW).[29][g] PoW imafuna kuti ogwira ntchito m'migodi apeze nambala yotchedwa nonce (nambala yomwe imagwiritsidwa ntchito kamodzi), kotero kuti pamene chipika zili mwachangu pamodzi ndi nonce, zotsatira zake zimakhala zocheperapo kusiyana ndi chandamale chovuta cha netiweki.[6]: ch. 8  Umboniwu ndi wosavuta kuti node iliyonse pamaneti itsimikizire, koma imatenga nthawi yambiri kuti ipange, ngati kachipangizo kotetezedwa, ochita migodi amayenera kuyesa mitundu ingapo yamitundu yosiyanasiyana (nthawi zambiri kutsatizana kwa miyeso yoyesedwa ndi manambala achilengedwe omwe akukwera: 0 , 1, 2, 3, ...) zotsatira zisanachitike kukhala zochepa kuposa chandamale chovuta. Chifukwa chandamale chovutirapo ndi chaching'ono kwambiri poyerekeza ndi ma hashi wamba a SHA-256, ma block hashi ali ndi ziro zambiri zotsogola[6]: ch. 8  monga tikuwonera pachitsanzo ichi block hash:
