Impi mayelana ne-Blocksize
I-Litecoin
Iqhinga elilodwa okwaxoxwa ngalo ku-Dragonsโ Den kulesi sikhathi kwaba ukusebenzisa i-SegWit ku-Litecoin, olunye uhlamvu lwemali, oluvame ukubhekwa njengesihlobo esiseduze ne-Bitcoin. Lokhu kuzobonisa abavukuzi ukuthi i-SegWit iyasebenza futhi ibonise ukuthi eziningi zokushiyeka ku-SegWit eziguqulelwe ama-blocker amakhulu, njengobuthakathaka bezokuphepha, empeleni zaziwumbudane. Iklayenti le-softfork le-SegWit likhishwe ngoJanuwari 12, 2017, kunguqulo ye-Litecoin engu-0.13.2.1. Ngokungafani ne-Bitcoin, eyayinomkhawulo wokuvula wamaphesenti angama-95, i-Litecoin yayinomkhawulo wokwenza kusebenze umvukuzi ongamaphesenti angama-75. I-Litecoin ibe namafasitela afanayo okuvuselela amasonto amabili, alandelwa isikhathi somusa samaviki amabili. Iningi lamanothi okukhululwa aleli klayenti abhalwe umthuthukisi we-Bitcoin ongaziwa obizwa ngokuthi "Shaolinfry", futhi iningi lekhodi ye-SegWit yakhiqizwa abathuthukisi be-Bitcoin. Cishe uShaolinfry wayezoba yilungu le-Dragonsโ Den; nokho, nangaphakathi eMgodini, ubuyena beqiniso balo muntu babengazi ngokuqinisekile. UCharlie Lee wayesungule i-Litecoin futhi wayebonakala ehlonza njenge-blocker encane. Ngesikhathi esifanayo, umphakathi wakwa-Litecoin ubonakale ukusekela ngentshiseko ukuqaliswa kwe-SegWit, njengoba lokhu kwakuyithuba labo lokuqalisa ubuchwepheshe obusha ngaphambi kwe-Bitcoin, okwakubhekwa njengento enhle kakhulu.
Ukusekelwa kwe-SegWit phakathi kwabavukuzi be-Litecoin kwanda kancane kancane, nokho kwakusephansi futhi kwakungaqiniseki ukuthi ukusebenza kuzokwenzeka. Cishe ngo-April 9, 2017, kube nomkhankaso we-softfork ecushwe ngumsebenzisi (i-UASF) ku-Litecoin, ukuphoqelela ukusebenza kwe-SegWit. Inhloso yomkhankaso kwaba ukukhungatheka kwabasebenzisi ngokungabi bikho kwenqubekela phambili kubavukuzi. Umbono lapha wawuwukuthi, kunokuba kube nomkhawulo wokwenza kusebenze umvukuzi, abasebenzisi bangasebenzisa iklayenti elingavele lenze kusebenze imithetho emisha endaweni ethile esikhathini esizayo, kungakhathaliseki isimo sokuhlaba umkhosi kwabavukuzi. Kuleli qophelo, umkhankaso wawuhilela ngokuyinhloko abasebenzisi ukungeza ifulegi elithi โUASF-Segwit-BIP148โ kumenzeli womsebenzisi weklayenti labo le-Litecoin, ukuze lo mlayezo ubonakale kunethiwekhi. Ayivulanga lutho nhlobo, kodwa ivele yasho inhloso yabasebenzisi.
I-Bitcoin yayike yasebenzisa le ndlela yokwenza kusebenze esikhathini esidlule, ngesikhathi sika-Satoshi, nokho i-Bitcoin yashintshela ekuhlabeni umkhosi kwabavukuzi ukuze kwehliswe amathuba anoma yikuphi ukuhlukana kweketango noma izinkinga ekusebenziseni. Kubonakale kimi ukuthi, ngenkathi ukusebenzisa indlela enjalo yokuvula ku-Bitcoin kungase kube yingozi, ikakhulukazi ekuthuthukisweni okuyimpikiswano njenge-SegWit, ku-Litecoin lokhu kungase kube lula. Ukusekelwa kwe-SegWit phakathi kwabasebenzisi kwakuseduze nendawo yonke, futhi i-Litecoin yaze yaba nomsunguli owayesebenza esikhaleni futhi esekela ukuthuthukiswa. I-UASF yabonakala isebenza; abavukuzi base bewutholile umlayezo futhi ukuhlaba umkhosi kwe-SegWit ku-Litecoin kwaqala ukwanda. Ukuqalisa manje kubukeka kuseduze.
Kodwa-ke, cishe ngo-Ephreli 17, 2017, i-hashrate ye-Litecoin yanda. Le hashrate entsha ibingahlabi umkhosi ku-SegWit futhi ibonakala ivimba ukuqalisa. Lokhu kubukeka njengesu lamabomu elivela kubavukuzi. I-hashrate ivele ku-LTC1BTC kanye namachibi e-LTC.TOP, alawulwa ngu-Jiang Zhuoer, owayebhekwa kabanzi njengommeleli we-Jihan Wu. Ngo-April 19, 2017, u-Jiang Zhuoer wabhala i-blogpost echaza isikhundla sakhe:
Nakuba nginokugodla kwami mayelana ne-Segwit (ngiyi-HODLER ye-Litecoin), uma kuyindlela eyamukelwa kabanzi eya phambili ngakho-ke angiyiphikisi. Kodwa ngimelene ngokuqinile namaqhinga asetshenziswa abalandeli be-Segwit, okuyi-UASF (DASF) kanye nobufakazi be-DDoS, ukuphusha ukuthi isebenze. Uma abasekeli bala maqhinga beqinisekiswa ngokubabona bephumelela ku-Litecoin, khona-ke kokubili i-Bitcoin ne-Litecoin iba amasistimu asengozini ethambekele ekukhohlisweni kobugebengu.
Ngenxa yalokhu, ngengeza i-hashrate eyanele echibini lami ukuze ngiqinisekise okulandelayo:
Ukuqinisekisa ukuthi i-Segwit ayisebenzi ngobufakazi be-DDoS. Ukuthi umphakathi wakwa-Litecoin uzolinda kuze kube yilapho u-Charlie Lee evakashela e-China ukuze enze lesi sinqumo ndawonye.
Manje sekubonakala sengathi izimpi zokukala zeBitcoin sezithuthele eLitecoin, cishe nekhophi yekhabhoni yezingxabano. Ngalesi sikhathi, ngakhuluma ngokuqondile noJiang Zhuoer. Wangichazela ukuthi wayengafuni i-SegWit ku-Litecoin, ngaphandle kwe-Litecoin futhi ibe nokunyuka kwe-hardfork blocksize. Kodwa-ke, lokhu akuzange kubonakale kunengqondo ngoba, ngokungafani ne-Bitcoin, i-Litecoin yayingenawo nhlobo amabhlogo. U-Jiang wangichazela ukuthi kwakumayelana nothishanhloko walesi simo: abathuthukisi be-Litecoin kwakudingeka "bakwenze kucace ukuthi bazokwenza i-hardfork lapho amabhulokhi egcwele", ngaphandle kwalokho lokhu kwakuyindlela engalungile. Wabe esengichazela ukuthi ukusebenzisa i-SegWit ku-Litecoin โkwakuwumdlalo we-Bitcoin Coreโ. Wayekhathazekile ukuthi, uma i-SegWit icushiwe ku-Litecoin, ingase isebenze naku-Bitcoin. Uphinde wathukuthela kakhulu nge-UASF ehlongozwayo, nokuthi lokhu kungaphinde kuzanywe kuBitcoin. Ngokubona kukaJiang, i-UASF โiphikisana nentshisekelo yabavukuziโ kanye โnesenzo esinobutha kubavukuziโ. Kwacaca kule ngxoxo ukuthi u-Jiang kanye nabanye babavukuzi babekhathazeke kakhulu futhi becishe besaba ithemba le-UASF, eyayizosusa umbono wokuthi abavukuzi babenezinga elithile lokulawula phezu kwephrothokholi.
Yebo, kwakukhona izinga elithile leqiniso kulokho uJiang ayekusho. Ngangazi ezingxoxweni ezisemhumeni ukuthi abavimbeli abancane babehlose ukusebenzisa ukusebenza kwe-SegWit ku-Litecoin ukuyisiza ukuthi isebenze ku-Bitcoin. Abavimbeli abakhulu babekutholile lokhu futhi manje kwadingeka bashintshe imizamo yabo yokumisa i-SegWit ku-Litecoin. Ngakolunye uhlangothi, kwacaca ukuthi umphakathi wangempela we-Litecoin usekele ngokuqinile ukuthuthukiswa, ngakho-ke mhlawumbe isenzo sabavimbeli abakhulu lapha sasingalungile kancane.
Ngomhla zingama-21 kuMbasa 2017, esenzweni esicacile sokukopisha i-Bitcoin, umhlangano we-Litecoin oyindilinga nabavukuzi abaningi wabanjelwa e-China, futhi kwashicilelwa isivumelwano:
Sikhuthaza ukuthi isinqumo sokuthuthukisa iphrothokholi ye-Litecoin kufanele senziwe ngokusekelwe ezidingweni zabasebenzisi, ngenqubo yokuvota yomhlangano we-roundtable, futhi sivuswe ukuvota kwabasebenzi basezimayini.

Asikhuthazi i-"UASF" yosuku lwefulegi engahambi noma (sic) noma yibaphi abasebenzisi noma inqubo yokuvota yomphakathi. Lolu hlobo lokuthuthukiswa okuphoqelekile ngaphandle kokuvumelana komphakathi lubeka i-Litecoin engcupheni yokuhlukana.
โฆ
Ngenqubo yokuvota, amalungu abambe iqhaza avumelana ngazwi linye nalolu hlelo olulandelayo mayelana nokuthuthukiswa kwephrothokholi ye-Litecoin:
Ukusebenzisa i-softfork yoFakazi Ohlukanisiwe ku-Litecoin. Lapho ukusetshenziswa kwe-bhulokhi lwe-Litecoin umthamo kungaphezu kuka-50%, sizoqala ukulungiselela isisombululo sokwandisa umkhawulo we-bhulokhi ye-1MB ngokusebenzisa i-hardfork noma i-softfork.
Okokugcina, sifuna ukugcizelela ukuthi lo mhlangano umele kuphela ukuvumelana kwamalungu abambe iqhaza, futhi awukwazi ukwenza isinqumo egameni lomphakathi we-Litecoin.
Isivumelwano sizibophezele ekusebenziseni i-SegWit, kodwa futhi savuma ukuqala ukulungiselela okunye ukukhushulwa komkhawulo we-blocksize, uma amabhulokhi esegcwele ngamaphesenti angama-50. Lokhu kuzwakale njengomsebenzi wokusindisa ubuso kubavukuzi; bazovula i-SegWit, kodwa bavikele esinye isithembiso esingacacile se-hardfork engaba khona. Eqinisweni, abavukuzi kungenzeka baphoqeleke ukuba basebenzise i-SegWit ngenxa yosongo lwe-UASF, okuyinto, esimweni se-Litecoin, yayingokoqobo kakhulu. Isivumelwano seBitcoin saseHong Kong sasisabalulekile kuJihan, futhi lena kwakuyindlela yokusho ukuthi basafuna into efanayo kuBitcoin, SegWit kanye nokwenyuka komkhawulo we-hardfork blocksize. Yiqiniso, e-Bitcoin, amabhlogo asevele egcwele ngaphezu kwamaphesenti angu-50, ngakho-ke i-hardfork yayidingeka manje.
Lesi sivumelwano futhi sasiqukethe izinto ezimbalwa ezazibonakala ziphikisana. Iqale ngokuthi izinqumo zephrothokholi kufanele zenziwe emhlanganenwi, kodwa isitatimende esifanayo kamuva sathi inqubo yomhlangano ayikwazi ukwenza izinqumo futhi umphakathi we-Litecoin ulawula. Lokhu kubonakale kukhombisa ukuthi akubona bonke emhlanganweni ababenombono ofanayo mayelana nokuphatha, futhi izigwebo ezingqubuzanayo zifakwe ukuze kushwelezwe izinhlangothi zombili. Iphinde yanikeza inkomba yokuthi uJihan kanye nabanye babavukuzi bazizwa benamandla kangakanani, ukuthi kwakuwukuthi abavukuzi ababelawula imithetho yephrothokholi. Kusukela ekukhulumeni nabo bobabili uJihan noJiang kulesi sikhathi, kwaba nomuzwa kimina ukuthi kancane kancane babebona ukuthi abavukuzi babengenawo amandla abake bacabanga ukuthi banawo, lokhu kwabakhungathekisa kakhulu futhi babelangazelela ukubambelela kulo mqondo ukuze inqobo nje uma bekwazi.
Ngokuthanda okuningi, i-Litecoin yabe ivula i-SegWit ngo-May 2017. Intengo ye-Litecoin yabe isikhuphuka kakhulu: ngokwengxenye ngenxa yenjabulo nge-SegWit; ngokwengxenye ngenxa yesu elivela kwabanye abavimbeli abancane lokuthenga i-Litecoin ukuze bakhuphule intengo futhi bakhe ukulandisa okuhle mayelana ne-SegWit; kodwa ikakhulukazi ngenxa yezimali eziningi ezigeleza esikhaleni njengoba i-khripthokharensi ka-2017 iqala. Amanye ama-Dragoni abe eseqala ukusabalalisa izindaba ezinhle mayelana ne-SegWit: ukuthi intengo ye-Litecoin inyukile nokuthi izibikezelo ezingamanga zosuku lwembubhiso ezivela kubavimbi abakhulu.
Lesi bekuyisiqalo esihle ku-2017 kubavimbi abancane. Babezuze ukunqoba okuthathu ngokulandelana: ukushintshana, i-ASICBoost futhi manje i-Litecoin. Ngehlobo lika-2017, amaphuzu onyaka ayenga amancaneavimbeli abathathu. Le mpi yayimayelana nomfutho, kanye nombono womfutho; abantu abaningi babefuna nje ukulandela iningi futhi babuyisele owinile. Umthelela onqwabelene walokhu kunqoba ube wusizo olukhulu. Abavimbeli abancane base bekhuphuka.
