I-Softfork Eyenziwe Umsebenzisi (User--Activated Softfork)
Umbono we-UASF ku-Bitcoin ukuxazulula inkinga yamanje kanye nokwenza kusebenze i-SegWit ubonakala sengathi uvela kumthuthukisi ongaziwa u-Shaolinfry, ku-imeyili ethunyelwe kuhlu lwamakheli e-Bitcoin ngo-February 25, 2017:
Inkinga nge-supermajority hash power signaling idonsa ukunaka okungadingekile kubavukuzi okungaba yipolitiki kungenasidingo. Osekuvele kuqondwe kabi njengevoti, abavukuzi bangase bazizwe benengcindezi โyokwenza isinqumoโ egameni lomphakathi: ukuthi ubani osayinayo noma ongasayini kuba yinto egxile kakhulu emphakathini futhi angase afake ingcindezi kubavukuzi abangayilungele. Abanye abavukuzi bangase bangabi sesimeni sokuthuthuka, noma bancamele ukungabambi iqhaza kwimfoloko ethambile okuyilungelo labo. Kodwa-ke, lowo mvukuzi manje angaba yisizathu esisodwa esenza ukuthi ama-veto asebenze kuwo wonke umuntu, lapho imfoloko ethambile iyisici sokungena! Lesi simo sibonakala siphikisana nemvelo yokuzithandela yohlelo lwe-Bitcoin lapho ukubamba iqhaza kuwo wonke amazinga kuwukuzithandela futhi kugcinwa kuthembekile ngezisusa ezilinganiselayo.

_Okunye okuxoxwe ngakho lapha โukwenza kusebenze usuku lwefulegiโ lapho amanodi eqala khona ukusetshenziswa ngesikhathi esinqunyiwe ngaphambili. Le ndlela idinga isikhathi sokuhola eside kunesicuphi sokuvula amandla esisekelwe ku-hashi, kodwa inikeza inani lezinzuzo futhi mhlawumbe inikeza ukushintjhisana okungcono.
Ngo-March 12, 2017, u-Shaolinfry wenza isiphakamiso sakhe ngokusemthethweni futhi saziwa ngokuthi i-BIP 148. Umbono wawuwukuphoqa abavukuzi ukuthi bahlabe umkhosi ukusekelwa kwe-SegWit ngomthetho wokuvumelana, ngaleyo ndlela bawenze kusebenze. Ngandlela thize, kwakuyi-softfork ukuvula enye i-softfork. Ukuhlatshwa umkhosi kwabavukuzi ngenkani bekuhlelelwe ukuthi kuqale ngo-Agasti 1, 2017, cishe kusasele izinyanga ezine nesigamu. Lokhu kungase kuqalise i-softfork yokuqala ye-SegWit, ngaphambi kokuthi kuphelelwe yisikhathi iwindi lokuvula.
Ukugqugquzela
I-Segwit ikhulisa usayizi wokuvimba, ilungisa ukusebenziseka kalula, futhi yenza ukubhala kube lula ukuthuthukisa kanye nokuletha ezinye izinzuzo eziningi.
Kuyethenjwa ukuthi abavukuzi bazosabela kule BIP ngokuvula i-segwit kusenesikhathi, ngaphambi kokuba le BIP iqale ukusebenza. Uma kungenjalo le BIP izobangela ukuthi kusebenze okuphoqelekile kokuthunyelwa kwe-segwit okukhona ngaphambi kokuphela kwaphakathi kwamabili Novemba 15th 2017.
Ukucaciswa
Zonke izikhathi zicaciswe ngokwesikhathi esidlule esimaphakathi.
Le BIP izosebenza phakathi kwamabili Agasti 1st 2017 (isikhathi se-epoch 1501545600) naphakathi kwamabili Novemba 15th 2017 (isikhathi se-epoch 1510704000) uma ukusetshenziswa kwe-segwit okukhona kungakhiyiwe noma kwenziwa kusebenze ngaphambi kwesikhathi se-epoch4 B5601 sisebenza lapho 56001 sisebenza. i-segwit ivaliwe.
Ngenkathi le-BIP isebenza, wonke amabhulokhi kufanele asethe amabhithi angu-3 aphezulu kunhlokweni abe ngu-001 kanye ne-bit field (1<<1) (ngokuhambisana nokusetshenziswa kwe-segwit okukhona kakade). Amabhulokhi angabonisi njengoba kudingeka azonqatshwa.
Umbono wawuphikisana kakhulu futhi ukunyakaza okuyingozi kakhulu, kusukela ekubukeni kwabavimbeli abancane. Okokuqala, ukulandisa okuningi kokuvinjwa okuncane kuze kube manje bekumayelana nesineke futhi kuguqule imithetho yokuvumelana kuphela ngendlela ezolile nephephile. Lokhu bekuwukuthuthukisa okuyingozi: bekudinga abavukuzi ukuthi bahlabe umkhosi ukwesekwa futhi, uma bengakwenzanga lokho, kungaholela ekuhlukaneni kwamaketango. Okwesibili, kwakuyingozi kakhulu ngoba, uma i-BIP 148 UASF ihluleka, okwakubonakala kungenzeka kakhulu, inganikeza isinyathelo kubavimbeli abakhulu. Kuleli qophelo lempi, abavimbi abakhulu base behlukene baba amaqembu amaningana: isibonelo, phakathi kwalabo ababekholelwa ukuthi uCraig Wright wayenguSatoshi kanye nalabo ababecabanga ukuthi uyiqili; phakathi kwalabo ababecabanga ukuthi i-Bitcoin Unlimited ingumbono oqinile nalabo ababecabanga ukuthi inephutha; naphakathi kwalabo ababeshiye ukwethula iminikelo yohlamvu lwemali olusha kanye nalabo abasala begxile kuBitcoin. Kodwa-ke, ngokubonga kwabo, kuze kube manje abavimbeli abancane base behlangene kakhulu. Lokhu bekungamandla ayisihluthulelo kuhlangothi oluncane lwabavimbeli futhi kwabasiza ukuthi bathole ukwaziwa okukhulu empini. Lo mdlalo obungundabamlonyeni wekampa yebhulokhi ubeka engcupheni yokuwahlukanisa kabili, obekungabalimaza kakhulu umgomo wabo.
Ngokwesibonelo, uGregory Maxwell, omunye wezihlakaniphi ezinethonya elikhulu ohlangothini oluncane lwabavimbeli, waphikisa i-UASF futhi wawubeka ngokucacile lo mbono nge-imeyili ngo-April 14, 2017:
Angiyisekeli i-BIP148 UASF ngenxa yezizathu ezifanayo engisekela i-segwit: I-Bitcoin iyigugu ngokwengxenye ngoba inokuvikeleka okuphezulu nokuzinza, i-segwit yaklanywa ngokucophelela ukusekela nokukhulisa lobo buqotho bobunjiniyela abantu abangathembela kubo manje futhi esikhathini esizayo.
Angizizwa ukuthi indlela (sic) ehlongozwayo ku-BIP148 ilingana ngempela nezinga elibekwe yi-segwit ngokwayo, noma izinqubo ezikhona ezingcono kakhulu zokuthuthukiswa kwephrothokholi kulo mphakathi.
Iphutha eliyinhloko ku-BIP148 ukuthi ngokuphoqelela ukwenziwa kusebenze kwamanodi akhona (okungewona awe-UASF) cishe kuqinisekisa ezingeni elincane lokuphazamiseka.
I-Segwit yakhiwe ngokucophelela ukuze abavukuzi abadala abangashintshiwe bakwazi ukuqhubeka nokusebenza _ngokuphelele_ ngaphandle kokuphazamiseka ngemva kokuqaliswa kwe-segwit.
Ama-nodi amadala angeke ahlanganise ukusetshenziswa kwe-segwit, ngakho-ke amabhulokhi awo ngeke abe angavumelekile ngisho noma engenakho ukwesekwa kwe-segwit. Bangakwazi ukuthuthukela kukho ngohlelo lwabo. Okuwukuphela kwengozi abavukuzi abangahlanganyeli abayithatha ngemva kokuqaliswa kwe-segwit ukuthi uma omunye umuntu emba ibhulokhi engavumelekile bazoyinweba, ingozi abavukuzi abaningi asebevele beyithatha njalo ngezinhloli.
Angicabangi ukuthi kuyisiphakamiso esibi: yenziwe kangcono kunezinto eziningi ezenziwa ama-altcoins amaningi, kodwa hhayi nje ngokwezindinganiso zethu ezijwayelekile. Ngiyazihlonipha izisusa zababhali be-BIP 148. Uma umgomo wakho kuwukwenza kusebenze i-segwit esheshayo ngakho-ke kusiza kakhulu ukusebenzisa i->80% yamanodi akhona asevele esekela inguqulo yokuqala ye-segwit.
Kodwa ukusekelwa okushesha kakhulu akufanele kube umgomo wethu, njengomphakathi- kuhlale kunohlelo oluthile lwe-altcoin noma oluphakathi nendawo olungasekela okuthile ngokushesha kunalokho esingakwenza- ukuzama ukufanisa okungase kucekele phansi ukubaluleka kwethu okusihlukanisayo ekuklanyweni kahle nasekuzinzeni.
โOkokuqala ungalimazi.โ Kufanele sisebenzise izindlela ezincane eziphazamisayo ezitholakalayo, futhi isiphakamiso se-BIP148 asihlangabezani nalolo vivinyo. Ukuzwa abanye abantu- okungebona abathuthukisi be-reddit futhi abanjalo- abambalwa baze babone ukuphoqelelwa kwentandane kwe-148 njengento enhle, ukuthi kuyisijeziso kubavukuzi abangaziphathi kahle. Angikwazanga (sic) ukuphikisa lowo mbono ngamandla.
Yebo, angiphikisani nomqondo ojwayelekile we-UASF kodwa _ngokuvamile_ imfoloko ethambile (yanoma yiluphi uhlobo) ayidingi ukuzifaka engcupheni yokuphazamiseka kwezimayini, njengoba nje ukwenza kusebenze i-segwit kungenasidingo. I-UASF iwuhlobo lokuqala lwemfoloko ethambile futhi bekuwukuphela kohlobo lwemfoloko eyenziwa nguSatoshi. I-P2SH yenziwe yasebenza ngokususelwe kwidethi, futhi konke okwangaphambili kwakusekelwe ezikhathini noma ubude. Sethule ukusebenzisa okusekelwe kumvukuzi njengengxenye yenqubo yokwenza i-Bitcoin izinze esimweni esivamile lapho umphakathi uhambisana khona. Kuyaxaka ukubona i-UASF ikhonjiswe njengento entsha.
Kubalulekile ukuthi abasebenzisi bangabi semseni wanoma iyiphi ingxenye yomphakathi ngezinga esingakugwema ngayoโ kungaba abathuthukisi, abahwebi, izinkundla zezingxoxo, noma abenzi bezingxenyekazi zezimayini. Ekugcineni imithetho ye-Bitcoin iyasebenza ngoba isetshenziswa abasebenzisi ngokuhlanganyela- yilokho okwenza i-Bitcoin i-Bitcoin, yikho okwenza kube yinto abantu abangathembela kuyo: imithetho akulula ukuyishintsha nje.
Kube khona ezinye iziphakamiso ze-UASF ezigwema ukuphazamiseka okuphoqelekile- ngokuchaza ingxenye entsha yofakazi kanye nokuvumela abavukuzi abangathuthukisiwe ukuya ku-uasf kanye nama-nodi ukuthi baqhubeke njengokungathuthukisiwe, ngicabanga ukuthi baphakeme kakhulu. Bazophuza ukuhambisa, kodwa angicabangi ukuthi lokho kuyiphutha.
Kufanele sibe nesineke. I-Bitcoin iwuhlelo okufanele luhlale kuyo yonke iminyaka futhi lunikeze amandla isintu isikhathi eside- iminyaka eyishumi kusukela manje iminyaka embalwa yengxabano izobukeka iyinto engekho. Kodwa idumela esilitholayo lokuzinza nobuqotho, ngokuba uhlelo lwemali abantu abangathembela kulo kuyosho yonke into.
Uma lezi zingxoxo zivela, zizovela ngendlela yokukhumbuza abantu ukuthi i-Bitcoin ayiguqulwa kalula nje, noma ngabe izifiso zinhle ngokusobala, nokuthi lokho kuyivikela kanjani ekuphathweni njengazo zonke izinhlelo ezincintisanayo. imali eyayisetshenziswa umhlaba wonke yayiphathwa. ๐
Ngakho yiba nesineke, ungathathi izindlela ezimfushane. I-Segwit iyintuthuko enhle futhi kufanele siyihloniphe ngokwazi ukuthi inhle ngokwanele ukuyilinda, futhi nokho ukuthi yenziwe yasebenza ngendlela engcono kakhulu esazi ngayo.
Omunye wabathuthukisi bokuqala be-Bitcoin abaziwayo ukusekela i-UASF kwakungu-Luke Dashjr, umthuthukisi owathola ukuthi kungenzeka kanjani ukwenza i-SegWit imfoloko ethambile kwasekuqaleni. U-Luke wayemise intamo yakhe lapha, esekela eminye imithetho yokuvumelana lapho cishe kungekho muntu owayenza. Nokho, ngenxa yobuntu bakhe, lokhu kwakungeke kumkhathaze, futhi kwakungabonakali. Omunye wabathuthukisi abahlonishwa kakhulu ekamu elincane le-bhulokhi, u-Pieter Wuille, owayebhale amakhodi amaningi e-softfork ye-SegWit, naye wamelana ne-BIP 148. NgoMeyi 2017, engxoxweni yokudluliselwa kwe-inthanethi no-Luke, u-Pieter wenza lawa mazwana alandelayo:
engikulindele ukuthi yonke i-nodi egcwele ehlobene ngokwezomnotho izobuyela emuva emahoreni ekhodi ye-bip148 ngemva kokuthi i-hashrate ihlulekile ukuyithatha

luke-jr: ngicabanga ukuthi uyahlanya
Kumele kuqashelwe ukuthi uPieter washeshe waxolisa ngala mazwana โohlanyayoโ. Uma kubhekwa imibono yabathuthukisi abafana noPieter noGregory, manje kwabonakala kungenakwenzeka kakhulu ukuthi i-Bitcoin Core ikhulule iklayenti elisebenzisa i-BIP 148. Uma uhlelo lwe-UASF lwaluzophumelela, abavimbeli abancane, ngokuxakile, kuzodingeka basebenzise elinye iklayenti elinezinhlobonhlobo. imithetho yokuvumelana, njengoba nje abavimbeli abakhulu babenze ngeBitcoin XT, Bitcoin Classic kanye neBitcoin Unlimited.
Yilokhu okwenzekile: U-Luke wagcina ekhiphe iklayenti esebenzisa i-BIP 148, enomaka we-ejenti yomsebenzisi othi โ/Satoshi:0.14.2/UASF-Segwit:0.3(BIP148)/โ. Abasebenzisi baphinde bakhuthazwa ukuthi baqhubeke nokusebenzisa i-Bitcoin Core futhi bashintshe i-ID ye-ejenti yomsebenzisi ukuze babonise ukusekela i-BIP 148, nayo eyayibonakala ingumkhuba odumile ngaleso sikhathi. Abanye baphikisa ngokuthi lokhu kwakuwumkhuba omubi njengoba iklayenti empeleni lingazange lisebenzise imithetho ye-BIP148, nokho abanye baphendule ngokuthi lokhu kwakumayelana nezinhloso futhi kubonisa ukuthi abasebenzisi bazothuthukisa ngaphambi kuka-Agasti 1. Abanye baveze ukuthi lokhu kwakuwukuzenzisa kancane, njengoba lokhu kwakuwuhlobo lokuziphatha abavimbeli abancane ababelugcona futhi bagxeka abavimbeli abakhulu.
Ekuqaleni kukaMeyi 2017, ngahlala phansi eHong Kong ukuze ngixoxe nomunye wabasekeli ababaluleke kakhulu basemuva be-UASF. Umthuthukisi engikhulume naye wayebhale ikhodi yeklayenti le-UASF futhi wagcina amawebhusayithi amaningi omkhankaso we-UASF. Ngamchazela ukuthi i-UASF yayiyingozi futhi kubalulekile ukubekezela ngemithetho yokuvumelana kweBitcoin. Wanikeza impendulo ende futhi eqinile. โEzikhathini ezijwayelekile, uqinisile,โ egomela, โkodwa-ke, akuzona izikhathi ezijwayelekile lezi, sisempini.โ Waqhubeka: โI-Bitcoin isesimweni esibucayi, i-Bitmain isebenzisa kabi ukuba sengozini kwe-ASICBoost, i-SegWit ilungisa lobu buthakathaka futhi sidinga ukulungisa lokhu ngokushesha. Kuyisimo esiphuthumayo ngakho-ke asinaso isikhathi sendlela ejwayelekile, yesiguli.โ Waqhubeka wachaza ukuthi, empini, awuhlali unakho ukunethezeka kokukhetha isikhathi esifanele. Wabonga ukuthi ukuqaliswa kwe-UASF kwakusenezinyanga ezimbalwa nje kuphela, kodwa wachaza ukuthi abavimbeli abancane okwamanje basesikhundleni esiphezulu empini futhi kwakungekho siqinisekiso sokuthi lokhu kuzohlala. โManje yisikhathi sokukhipha izikhali ezinkulu,โ ememezela, โlapho sesinamandla.โ Uqhube wathi: โAsinayo enye indlela esingayenza, sidinga ukuthatha isinyathelo manje, sihambe ngezikhali zenuzi futhi siyinqobe le mpi, ngekusasa leBitcoin. Uma singakwenzi lokho, sizifaka engozini
Nakuba, ekuqaleni, lo mbono wawuyimpikiswano ngaphakathi kwekamu elincane le-block, ngo-May 2017 lase lithole ukuthinteka okuphawulekayo. I-Dragons 'Den manje yayisikwimodi yomkhankaso ephelele, isekela i-BIP 148 kanye ne-UASF. U-Samson Mow useze wahlela, wathengisa futhi wasabalalisa isigqoko esinezinhlamvu ezihlotshiswe nge-UASF ngaphambili. Lesi sigqoko ngokuvamile sasinemibala yezempi futhi sigqokwa abavimbeli abancane ezingqungqutheleni ze-Bitcoin nemicimbi ukukhombisa ukusekela kwabo lo mkhankaso ovela emazingeni aphansi. Kuleli qophelo, ingxoxo ye-UASF yayidlange kuphela ngaphakathi komphakathi wamabhulokhi amancane, kuyilapho abavimbeli abakhulu kanye nomkhakha obanzi we-cryptocurrency ngokuvamile bekushaya indiva. Kwaba ngasekupheleni kukaMeyi 2017 lapho umbono usuhlolisiswa kabanzi ngaphandle kwekamu elincane le-bhulokhi.
Ngokombono weqhinga, abavimbeli abakhulu bephuze kakhulu ukusabela futhi bephuza kakhulu ukuqonda i-UASF. Abavimbeli abakhulu bekufanele babone ukuhlukana okungenzeka ekamu elincane le-block futhi bazame ukukugqamisa nokukusebenzisa, njengoba nje abavimbeli abancane benzile ngokuhlukana okungenzeka ekamu elikhulu labavimbeli. Esikhundleni salokho, bayishaya indiva i-UASF. Ngasekupheleni kukaMeyi, ngakhuluma nomunye wabavimbeli abakhulu abavelele ukuxoxa nge-UASF. Wangichazela ukuthi wayengakholelwa ukuthi uGregory Maxwell wayephikisana ngempela ne-UASF; โkwakungamanga nemidlaloโ yakhe nje, echaza. Kwakubonakala sengathi, ngalesi sikhathi, izinga lokungathembani laliphezulu kangangokuthi, kuhlangene nokuqonda okuhluke kakhulu kokuthi i-Bitcoin isebenza kanjani, abavimbeli abakhulu bacishe bangakwazi ukutshela ukuthi abavimbeli abancane babenzani. Kimina kwabonakala sengathi abavimbeli abancane base besukile futhi bashiya indawo evulekile. Uma le mpi yayizoqhubeka, abavimbeli abakhulu babedinga ukusabela futhi basebenzise ukuvulwa, kodwa abazange babonakale beqonda ukuthi benzeni.
Abavimbeli abakhulu nabo babonakala bekhathazeke ngokweqiniso yi-UASF. Ekuqaleni kwempi, babebukele phansi kakhulu ubukhulu nethonya lekamu elincane labavimbi, belindele ukunqoba okulula empini. Abavimbeli abakhulu babevame ukuklolodela abavimbeli abancane njengabangabalulekile futhi abangenalwazi. Nokho, kuleli qophelo, ngemva kwemizamo emithathu ehlulekile ye-hardfork - ukuhlulwa okwabamangaza - iningi labavimbeli abakhulu manje babonakala beqina ngokweqile amandla nomthelela wabavimbeli abancane. Eqinisweni, abavimbeli abancane babenamandla amancane kakhulu kunalokho ababekucabanga; isizathu esiyinhloko sokuphumelela kwabo ekunqobeni abavimbeli abakhulu kuze kube yileli phuzu kwakuwukuqonda kwabo okuphakeme kwe-Bitcoin, amaphutha ahlakaniphile avela kubavimbi abakhulu ngokwabo kanye nokuqina kwe-Bitcoin ngokumelene nezinguquko zemithetho yephrothokholi ephikisanayo. Ngenxa yokuqonda okungaphelele, okungenani ngokwezinga elithile, abavimbeli abakhulu esikhundleni salokho basola ukunqotshwa kwabo ngobuqili obuvela kubavimbi abancane abanobuqili nabanamandla. Ngakho-ke, abavimbeli abakhulu babonakala behlonipha abavimbeli abancane futhi abaningi babo besaba i-UASF, ababeyibona njengomdlalo omkhulu olandelayo wabavimbeli abancane. Bebengaboni ngaso linye ithuba leqhinga elalibanika lona. Ngakho-ke ithuba abahlulekile ukulisebenzisa.
Kuleli qophelo, i-UASF cishe ayinakho ukusekelwa okuvela ekuhwebeni kwe-cryptocurrency. Iningi lama-CEO okushintshana engangikhulume nawo ngaleso sikhathi lalilindele ukuthi i-UASF ingaphumeleli, noma babengazi nokuthi kuyini. Izinga lokusekelwa kwezomnotho kwe-UASF ngaphandle kwekamu elincane le-bhulokhi lalincane. Lokhu bekuwumnyakazo oyingozi ovela kubavimbeli abancane, futhi kubonakala sengathi kungenzeka kimi ukuthi bangase bashiywe ku-blockchain ephansi yobufakazi bomsebenzi ethathwa njenge-Bitcoin. Okufanele ngabe abavimbeli abakhulu bakucabangele ukukhululwa kwe-"counter-softfork", eyavimbela amafulege we-BIP 148 emabhuloki. Lolu chungechunge lungaba neningi lezomnotho kanye ne-hashrate enkulu. Lesi sibali se-UASF besizoqinisekisa nokuthi sihlukana kahle, kanti iketango elingelona i-UASF lingasenabungozi bokwesulwa. Kodwa-ke, lena akuyona nje indlela abavimbeli abakhulu ababecabanga ngayo. Babefuna ukwanda kwe-hardfork blocksize; babengenabo ubuchwepheshe noma isifiso sokusebenzisa i-counter-softfork.
UJihan Wu ubonakale ecasulwe kakhulu wumkhankaso we-UASF. Kuye, i-UASF yabukela phansi ukulandisa ayekwakhile ukuthi abavukuzi babe nomthelela omkhulu phezu kwemithetho yephrothokholi. NgoMeyi 28, 2017, uJihan wabhala ngethegi ethi #UASF eceleni kwesithombe sezisulu zokubulawa kwesibhicongo saseJonestown. Intukuthelo nokwesaba ayenakho nge-UASF kwabonakala kunamandla.
Maphakathi noJuni, ukushintshaniswa kwe-ViaBTC, okwakuxhunywe ku-Jihan Wu, kufakwe kuhlu lwekusasa le-BIP 148 endaweni yesikhulumi. Lokhu kwakuwumqondo ocacile othathwe ku-Bitfinex ezinyangeni ezimbalwa ngaphambili kanye nethokheni yabo ye-Bitcoin Unlimited. Kwakungumzamo wokubukela phansi i-BIP 148, njengoba nje ikusasa le-Bitfinex lalibukele phansi i-Bitcoin Unlimited. Kodwa-ke, imibandela yenkontileka yayiyinqaba futhi inamaphutha. Uma umuntu etshale imali kuthokheni ye-BIP 148, ungathola inkokhelo kuphela uma kokubili iketango lethokheni le-BIP 148 kanye neketango lemithetho yasekuqaleni (iketango elingelona i-BIP 148) liqhubeka nokuba khona. Lokhu ngokusobala akuyona into ebifunwa ngabasekeli be-BIP 148. Babekholelwa ukuthi uchungechunge lwemithetho yokuqala luzophela, ikakhulukazi ngoba uchungechunge lwemithetho yasekuqaleni lwalusengozini yokusulwa ochungechungeni lwe-BIP 148. Ngakho-ke, ukutshala imali kuthokheni encike ekubeni khona okuqhubekayo kweketango le-non-BIP 148 kwenza umqondo omncane kubasekeli be-BIP 148. Inkontileka yehlulekile ukufeza noma iyiphi ivolumu yokuhweba ebalulekile futhi ayizange ibonakale ibukela phansi imbangela ye-BIP 148.
Ngomhla ziyi-14 kuJuni, i-2017, i-Bitmain ishicilele ibhulogi echaza uhlelo lwezimo eziphuthumayo ekuphenduleni i-UASF:
BIP148 iyingozi kakhulu ekuhwebeni namanye amabhizinisi. Alukho uphawu lokusekelwa okubalulekile kwezomnotho ngemuva kwe-BIP148 futhi lapho iphila njenge-blockchain, ukusekelwa kwezomnotho cishe kuzosuselwa ekuqageleni. Umsebenzi wezimayini ngemuva kochungechunge lwe-UASF ungase ume ngaphandle kwesaziso, futhi abatshalizimali abathenga inkulumo-ze ye-BIP148 bangase balahlekelwe yikho konke ukutshalwa kwezimali kwabo. Noma ikuphi ukuhwebelana okunquma ukusekela ithokheni ye-UASF ngemuva kwephuzu lokufoxa kumele kubhekwe ingozi yokuma enamathiselwe kukho.

Uchungechunge lwe-UASF luveza ubungozi bokwesulwa kweketango lokuqala. Uma lungekho uhlelo lwezimo eziphuthumayo, yonke imisebenzi yezomnotho eyenzeka ochungechungeni lokuqala ngemuva kwephuzu lokufola le-UASF izobhekana nengozi yokuqedwa. Lokhu kunemiphumela eyinhlekelele kuyo wonke umphakathi we-Bitcoin. I-UASF iwukuhlasela kwabasebenzisi namabhizinisi angavumelani nokuvula i-SegWit njengamanje ngaphandle kokukhushulwa kosayizi webhulokhi, okuyisigatshana esibaluleke kakhulu esivumelwaneni sase-Hong Kong esenziwe umphakathi we-Bitcoin womhlaba wonke ngoFebhuwari, 2016.

I-Bitmain izomba iketango okungenani amahora angu-72 ngemva kwephoyinti lokufola le-BIP148 ngephesenti elithile lesilinganiso se-hashi elinikezwa imisebenzi yethu yezimayini. I-Bitmain cishe ngeke ikhulule ngokushesha amabhulokhi ambiwe kunethiwekhi yomphakathi ngaphandle uma izimo zidinga lokho, okusho ukuthi i-Bitmain izomba iketango elinjalo ngasese kuqala. Sihlose ukuthi kulezi zimo ezilandelayo sikhulule amabhlogo ambiwe emphakathini (uhlu olungaphelele):
Iketango le-BIP148 liyasebenza futhi ngemva kwalokho lizuza ukwesekwa okubalulekile embonini yezimayini, okungukuthi ngemva kokuba i-BIP148 isivele ihlukanise ngempumelelo iketango;Imizwa yemakethe ye-hardfork iqinile(https://twitter.com/el33th4xor/status/867065862657900545), a ingqondo yezomnotho isishukumisela ukuthi siyimayini, isibonelo, izinga lokushintshisana livuna okukhulu -vimba i-Bitcoin;Uma sekuvele kunenani elikhulu labanye abavukuzi abamba uchungechunge lwamabhulokhi amakhulu esidlangalaleni futhi sinquma ukuthi kunengqondo ngathi ukuthi simbe phezu kwalelo ketango. Esimeni esinjalo, sizophinde sicabangele ukujoyina lelo ketango futhi siyeke uchungechunge lwethu olumbiwa ngasese ukuze iketango lomphakathi le-UAHF lingabi sengcupheni yokuhlelwa kabusha.

Uhlelo lwe-Bitmain bekuwukwenza kusebenze i-hardfork ngesikhathi esifanayo njengoba i-UASF yayizosebenza, okuzokwandisa umkhawulo wokuvimba. Uhlelo lwe-hardfork lwafaka nesimiso sokukhushulwa komkhawulo we-blocksize. Umkhawulo we-blocksize uzoqala ku-2 MB ngo-Agasti 2017, bese ukhuphuka kancane kancane ezinyathelweni ezengeziwe, ezinqunywe kusengaphambili ku-16.8 MB ngo-Agasti 2019. Lolu hlelo lubonakala luwuhlobo oluthile losongo, oluhloselwe abasekeli be-UASF. Abavimbeli abakhulu babezothola iketango labo elisha le-hardfork, into ababebona ukuthi abavimbeli abancane babenethemba elikhulu lokubavimbela ekufezeni.
Nakuba u-Jihan engazange abonakale ekubona, lolu hlelo empeleni lwaluvuna imbangela ye-UASF, ngoba kwakusho ukuthi iketango le-UASF lalingase lithole ukuhola kobufakazi bomsebenzi phezu kweketango lemithetho yokuqala, njengoba i-Bitmain ibonise ukuthi uhlele ukuthuthela kwelinye iketango le-hardfork. Ngaphezu kwalokhu, i-Bitmain ihlele ukumba imayini entsha ye-hardfork ngasese, isikhathi esingamahora angu-72. Lokhu bekuyisinyathelo esibi kakhulu, uma uhlelo bekuwukuba iketango eliqinile lithole noma yikuphi ukudonsa, njengoba kungekho muntu ozokwazi ukubona iketango, noma aqhube iklayenti elisekelayo, futhi ukuhwebelana bekungeke kukwazi ukusekela uphawu. Akukacaci ukuthi yini ebigqugquzele le bhulogi. Kubonakala sengathi u-Jihan wayethukuthele kakhulu futhi ngokushesha wenza icebo eliklanyelwe ukukhungathekisa abamelene naye, kodwa wayengakacabangi nhlobo. Okufanele uJihan akumemezele, yiqiniso, ukuthi, uma kwenzeka i-UASF, uzogcina izimayini uchungechunge lwemithetho yokuqala futhi okwamanje uhlele i-counter UASF. Kodwa-ke, lokhu bekuzomshiya enamathele kumabhulokhi angu-1 MB, ngakho-ke mhlawumbe wayenomuzwa wokuthi wayengenayo inketho enkulu.
Ngaphakathi kwe-Dragons 'Den, abavimbeli abancane bagubha i-posti ye-Bitmain ngenjabulo, njengoba cishe yabaqinisekisa ngokunqoba okuphelele. Kodwa-ke, abanye bathatha ithoni yokuqapha, "ngoba nje uJihan ethi uzokwenza into ewubuwula, ungacabangi ukuthi uzokwenza". Kimina kwabonakala sengathi lesi simo sokuqapha kwakuyindlela efanele. Njengoba u-Agasti 1 esondela, u-Jihan wayezobona ukuthi icebo lakhe lalingenangqondo futhi ligxile kwenye into esebenza kangcono.
Njengoba umnqamulajuqu we-UASF usondela, abavimbeli abakhulu basemuva njengoba babengazi ukuthi baphendule kanjani ngokuphumelelayo. Kwaba sengathi abanazo izinketho ezisebenzayo ezisele. Kwakubonakala sengathi abavimbeli abakhulu ekugcineni sebebheke ekuhlulweni okuhlazisayo, futhi babekwazi. Babedinga uhlobo oluthile lokuzivocavoca okusindisa ubuso.
