Andiyiqondi ukuba kutheni yonke ingcaciso malunga neHedera Hashgraph inikezelwa ngendlela edidayo, nokuba oku kubangelwa umgaqo-nkqubo wokuqonda wabaphuhlisi okanye kwenzeka nje ngengozi. Kodwa nakweyiphi na imeko, ukubhala isicatshulwa esihambelanayo malunga neHedera Hashgraph kwaba nzima kakhulu. Ngalo lonke ixesha kwakubonakala ngathi le nto, ekugqibeleni ndayiqonda yonke into, ngokukhawuleza kwacaca kwakhona kwaye kwakhona ukuba le yinkohliso enzulu. Ekugqibeleni, kubonakala ngathi into enentsingiselo yaphuma, kodwa kunjalo - funda ngokucophelela, ingozi yokukhupha ingqondo yakho ayizange ihambe.
Icandelo 1. Umsebenzi wabaphathi baseByzantine kunye nokuhleba
Embindini weli bali yinto ebizwa ngokuba yiByzantine Fault Tolerance (BTF), umfuniselo wengcinga olungiselelwe ukubonisa ingxaki yokuvumelanisa imeko yeenkqubo kwimeko apho unxibelelwano luthathwa njengoluthembekileyo, kodwa iindawo azikho. Nabani na onomdla angawufunda lo mba apha okanye apha ngokubanzi.
I-algorithms ye-platform ye-Hedera Hashgraph yakhiwe kwimeko ekhethekileyo ye-Byzantine Fault Tolerance, i-Asynchronous Byzantine General Task, okanye i-aBFT. Ngo-2016, isazi semathematika uLemon Baird waqala ukucebisa isisombululo kuso kwaye, ungabi sisidenge, ngoko nangoko unelungelo lobunikazi.
I-platform ye-Hedera Hashgraph ibonakaliswe ngokwabelana kunye nokulungelelaniswa kwedatha yedijithali ngokwe-algorithm yokuvumelana, ukunyanzeliswa ngokomzimba kweendawo zokugcina idatha kunye nokungabikho kweziko elilodwa lolawulo. Nangona kunjalo, i-protocol ye-Hashgraph (kule meko, i-Hedera yi-eco-environment, i-Hashgraph yi-protocol) ayiyoye-blockchains, kodwa yi-digraph engenazo imijikelo elandelelanayo kwaye iquka ulandelelwano oluhambelanayo oluqala kwindawo enye kunye nokufikelela ekupheleni. ngeendlela ezahlukeneyo.
Ukuthetha nje, ukuba ibhloko ye-blockchain yakudala inokuboniswa ngokubonakalayo njengolandelelwano olungqongqo lwekhonkco (leyo, eneneni, iyipropathi yayo ephambili), emva koko iHashgraph ibonakala ifana nebhonsai enenani elikhulu lamasebe. Ekubeni inani lemijikelo ngaxeshanye alinamda, iHashgraph ivumela inani elikhulu lentengiselwano ukuba yenziwe ngaxeshanye (abaphuhlisi bathi i-250 lamawaka ngomzuzwana, okuphindwe kahlanu amandla eVisa, singasathethi ke ngenethiwekhi yeBitcoin), kwaye ngokuqhelekileyo akukho ntlawulo yentengiselwano .
Umahluko olandelayo osisiseko phakathi kweHashgraph kunye ne-blockchain yakudala yiprotocol engaphantsi kwentlebendwane. Ngaphakathi kwileja esasaziweyo, intengiselwano nganye ayithethi ukudluliselwa kwayo yonke idatha, kodwa ulwazi kuphela malunga nolwazi (Intlebendwane malunga neGossip). I-node ikwazisa ezinye ii-node ezimbini ezichaseneyo malunga nokuthengiselana, nganye apho, ngokulandelelana, isasaza imiyalezo kwabanye ababini kude kube ngumzuzu apho inani lee-node ezichaziweyo lanele ukufezekisa ukuvumelana, kwaye oku kwenzeka xa uninzi lweenodi zikwaziswa ( kwaye kanye ngenxa yoku inani elichaziweyo lentengiselwano ngeyunithi yexesha liphunyeziwe).
Icandelo 2. Umbulali weBlockchain okanye cha
I-Hedera Hashgraph okwangoku iphantsi kophuhliso. Ngokukodwa, sivavanya eyethu i-cryptocurrency ngenkxaso ye-micropayments, inethiwekhi yokugcinwa kweefayile kunye nezikripthi ezisivumela ukuba senze izivumelwano ezihlakaniphile ngokusekelwe kwiilwimi ze-Ethereum.
Izimvo ngale projekthi azifane zibekho phakathi. Eminye imithombo ibiza iHashgraph "umbulali we-blockchain", abanye babonisa ngokufanelekileyo ukuba akukho mizekelo yokusebenza kwezicelo ezinikezelweyo kwindawo ye-Hedera, abanye babhidekile kukuba isiseko seqonga sinelungelo lobunikazi, kwaye uphuhliso lwalo luphantsi ulawulo lwebhodi yokulawula, ebandakanya abameli beqela leenkampani ezisuka kuluhlu lwe-Fortune 500 (nangona le yokugqibela ithetha nje ukuba iprojekthi inamandla okwenene kwaye ngokuqinisekileyo ayisiyo scam). Ngendlela, kwixesha elidlulileyo le projekthi yachithwa kwinkampani eyahlukileyo, iHedera Hashgraph, ekwabonisa ukubaluleka kwayo kubaphuhlisi.
Abaphuhlisi, ngaphandle kwengxabano enkulu, baqokelele kuqala i-18 yezigidi zeedola kwiimfuno zokusebenza kwintengiso yomqondiso ovaliweyo kwaye, emva kwexesha elithile, enye i-$ 100. Akukho zinkcukacha malunga ne-ICO nazo zaxelwa, kwaye ngokubanzi, i-Hedera Hashgraph imephu yendlela ayifane iqondwe, nto leyo. ayithinteli inkampani ukuba iqhube imisebenzi esebenzayo ejolise ekwaziseni le algorithm yemvumelwano, inkampani isebenza ngokukhutheleyo ekusekweni kweendawo ezahlukeneyo zeengcali - ukusuka kubadwelisi benkqubo ukuya kumagqwetha, abameli beprojekthi sele bebambe iintlanganiso ezingaphezu kwama-80 kunye nabemi abanomdla emhlabeni jikelele. ihlabathi, kwada kwafikelela eRashiya - ngo-Matshi 6, intlanganiso yabanjwa eMoscow kunye noMongameli weHedera Hashgraph uTom Trowbridge, abathi, njengoko bethetha, badibanisa abameli abaninzi be-IT yethu kunye nezangqa zemali.
UMnu Trowbridge uthe kwixesha elizayo ubuncinane izicelo ze-40 ezisekelwe kwi-Hedera Hashgraph kulindeleke, kwaye ngokubanzi kukho ngaphezu kwe-100 yazo esebenzayo, ngoko kwixesha elizayo wonke umntu uya kuba nethuba lokubona indlela olu qoqosho lusebenza ngayo. .
Iyonke
Ngokubanzi, izinto ezininzi zinokuthethwa ngokuqinisekileyo. Okokuqala, le projekthi ayibalulekanga kwaye sele ivuse umdla omkhulu kubameli bamashishini amakhulu. Okwesibini, kumntu ongeyongcali akaqondi ngokunyanisekileyo, ngokucacileyo, uchaza ukungabikho kwedatha malunga naye kwindawo yoluntu (kwaye kwakhona, ukugweba ngevidiyo kunye noMnu Limon, kunye nenyaniso yokuba lo mfo ohlakaniphile akaze isithethi kwaphela). Okwesithathu, akunakwenzeka ukuba iya kuba "ngumbulali weBitcoin" okanye into ebuhlungu ngokulinganayo, kodwa izibonelelo zayo ezichaziweyo zibonakala zibalulekile ngokwaneleyo ukulandela iprojekthi ngokusondeleyo.
Ngaphezu koko, kukho amahemuhemu okuba abaququzeleli kungekudala baya kutsala icandelo elilandelayo lotyalo-mali, kunokwenzeka ukuba kuyavakala ukuba bathathe inxaxheba kuyo.
