Ngoku ujonge Yintoni iiNodes?

Zithini iiNode?

Ixesha lokufunda: 5 imizuzu

I-node inentsingiselo eyahlukileyo esekwe kwimeko yayo.

Kwilizwe lothungelwano, iinethiwekhi zonxibelelwano ngocingo okanye iikhompyuter, ii-node zineempawu ezichazwe kakuhle: zinokuba yindawo yokwabiwa ngokutsha okanye indawo yokuphela konxibelelwano. Singatsho ngokubanzi ukuba i-node sisixhobo sothungelwano lomzimba. Ukuze ungaphoswa nayiphina into, nangona kunjalo, kukho iimeko ezithile ezithile apho kufanelekileyo ukuba kusetyenziswe iindawo ezibonakalayo.

Cazoo, thetha ngokusela!

Iyahamba ngebhon. I-node yenethiwekhi yindawo apho umyalezo unokwenziwa, ufunyenwe okanye uhanjiswe. Njengoko sele kukhankanyiwe, kukho iintlobo ezahlukeneyo zeendawo zeBitcoin: iindawo ezipheleleyo, iindawo eziphezulu, iindawo zokumbiwa kwemigodi kunye nabathengi be-SPV.

Iimpawu zeBitcoin

Apho iBlockchain yenzelwe khona njengenkqubo isasazwe, uthungelwano lweendawo luvumela i-Bitcoin ukuba isetyenziswe njenge-peer-to-peer (P2P) yemali yedijithali, enganyamezelekiyo kunye nokwabelwa amagunya, oko kukuthi, ngaphandle kokuba kufuneke kubekho abalamli ukuze kuqinisekiswe urhwebo, ukutshintshiselana, ukuthengiselana phakathi kwabasebenzisi.

I Iibhloko ze blockchain Kufuneka ke ngoko basebenze njengendawo yokunxibelelana kwaye babenakho ukuba neepropathi ezithile, ukuze bakwazi ukwenza imisebenzi ethile. Nasiphi na isixhobo edibanisa ujongano lweBitcoin, njengekhompyuter, ingaqwalaselwa njengeqhina, kuba zonke iindawo zixhunyiwe ngaphakathi kwe-blockchain. Yintoni enokwenziwa ngala maqhina? Bayanxibelelana. Bathumela ulwazi malunga nokuthengiselana kunye neebhloko zothungelwano lwazo lwekhompyuter olusasazwe kunye nomgaqo-nkqubo woontanga kaBitcoin. Iliso: Kukho iintlobo ezahlukeneyo zeendawo zeBitcoin.

Iindawo ezipheleleyo

Iindawo ezipheleleyo zezi ndawo ezinikezela ngokhuseleko lweBitcoin kwaye zixhasa ubume bayo: zibalulekile ekusebenzeni kwenethiwekhi yonke. Mhlawumbi sele uzifundile kwenye indawo kwaye uzibone zibizwa iindawo eziqinisekisa ngokupheleleyo: bababiza njalo kuba ukuthatha inxaxheba kwinkqubo yokuqinisekisa ukuthengiselana kunye nokutshixa ngokwemigaqo ebekwe ngu imvume yenkqubo. Iindawo ezipheleleyo zingadlulisa ukuthengiselana okutsha kunye neebhloko ezintsha kwi-blockchain.

Ngokwesiqhelo indawo yokugqibela kufuneka ikhuphele ikopi yayo yonke ibhloko, kunye nazo zonke iibhloko kunye nokuthengiselana (nokuba ayiyomfuneko ukuba ithathelwe ingqalelo njengeyona ndawo ilungileyo-nokuba yinxalenye enye ye-blockchain inokukhutshelwa).
I-Bitcoin node epheleleyo inokumiselwa emva kokuphunyezwa kwesoftware eyahlukeneyo, apho kwaziwa khona konke Bitcoin Core (nantsi ikhonkco le-github yakhe). Ayenzelwe wonke umntu! Nantsi ubuncinci, kodwa ubuncinci, ubuncinci beemfuno zokuba yi-Bitcoin Core node epheleleyo:

  • Idesktop okanye ilaptop enenguqulo yeWindows, iMac OS X, okanye iLinux.
  • I-200GB yendawo yasimahla yediski.
  • 2GB yememori (RAM).
  • Isantya esiphezulu sonxibelelwano lwe-intanethi kunye nokulayishwa okungenani okungama-50 kB / s.
  • Unxibelelwano olungasikelwanga mda okanye ngemida yokulayisha ephezulu. Okanye qiniseka ukuba kwisicwangciso sakho somrhumo, ukuba wenza i-hotspot, i-200 giga ngenyanga yokulayisha kunye ne-20 kwi-downlaod ifakiwe.
  • I-node epheleleyo kufuneka ikwazi ukusebenza ubuncinci ikota yosuku (iiyure ezi-6) kodwa kuyabulelwa ukuba ihlala isebenza, iiyure ezingama-24 ngosuku.

Amawakawaka amavolontiya ahlukeneyo kunye nemibutho basebenza nzima ukuba babe ziindawo ezipheleleyo kwaye ke bakwazi ukunceda i-Bitcoin ecosystem. Ukusukela namhlanje (ngoMeyi 2021) siyabala 9615 iindawo ezisebenzayo zoluntu kwinethiwekhi yeBitcoin. Kwaye sithetha nje ngeendlela zasesidlangalaleni, oko kukuthi, iindawo ezibonakalayo zeBitcoin nezifumanekayo - ezibizwa nangokuthi iindawo zokuphulaphula

Isishwankathelo seendawo zoluntu zenethiwekhi yeBitcoin

Ewe uSherlock, zikhona iindawo ezingamameliyo, amaqhina afihliweyo nanganakubonwa. Ezi zifihla ngasemva kwe-firewall ukuze zisebenze, zisebenzisa iiprothokholi zabucala ezinje ngeTor, okanye, nokuba zilula kwaye zikhuselekile, azimiselwanga ukufumana unxibelelwano.

Iindawo zokuphulaphula (iiNow Super)

Un node yokumamela o Indawo ephezulu yindawo ebonakalayo ebonakalayo esidlangalaleni: iyanxibelelana nezinye iindawo ezifuna ukuthetha nayo kwaye ibelane ngolwazi. Isetyenzisiwe eyona ndlela iphambili zombini ibhulorho yonxibelelwano che Umthombo wedatha: indawo ephezulu ngu Indawo yokwabiwa ngokutsha komhlaba.

Ukuba ufuna ukuba yindawo ephezulu ethembekileyo, kufuneka uhlale usebenza, iiyure ezingama-24 ngosuku, ukuze ukwazi ukuhambisa unogumbe wonxibelelwano: imbali ye-blockchain kufuneka ibhalwe, yonke imicimbi kufuneka irekhodwe kunye nedatha kuzo zonke iindawo ehlabathini. Ayitsho ngaphandle kokuba yeyabantu abambalwa: kufuneka amandla ekhompyuter afunekayo, kunye nonxibelelwano olungcono lwe-intanethi.

Iindawo Zemigodi

Ixesha lokumba umgodi lidlulile. Sukuqala ukujongela phantsi. Namhlanje, ukuze uthathe inxaxheba ngokukhuphisanayo kwinkqubo yemigodi yeBitcoin, kubalulekile ukuba utyale imali kwiinkqubo ezikhethekileyo kunye nezixhobo, ezihamba ngokudibeneyo neBitcoin Core ukuzama ukwenza iibhloko. Umsebenzi wasemgodini, okanye umntu osebenzisa ezi khomputha zinamandla, unokuthatha isigqibo sokusebenza yedwa (mgodini kuphelaokanye ngokwamaqela (umgodi wamachibi). 

Ngelixa iingcuka zodwa, abasebenza emgodini kuphela abacele umakhulu wabo ukuba bakwazi ukusebenzisa igumbi elingaphantsi komhlaba ukwenza izinto ngeekhompyuter, ngelixa besebenzisa ikopi yabo yasekuhlaleni ekhutshelweyo ye-blockchain, abo benza imigodi emachibini, kumadama okudada Abasebenzi basemgodini, basebenza kunye nje, kwaye ngamnye enegalelo kwizixhobo zakhe (amandla). Kwichibi lezemigodi luxanduva lodwa lomlawuli wedama lokugcina indawo epheleleyo: uyi umvukuzi opheleleyo wenode.

Ubunzima okanye umxhasi we-SPV

Ikwabizwa ngokuba ngabaxhasi be-SPV) abaxhasi, abathengi KDEName Basebenzisa inethiwekhi yeBitcoin kodwa abenzi njengendawo epheleleyo. Abathengi be-SPV ke abanalo igalelo kukhuseleko lwenethiwekhi: Akukho mfuneko yokuba babe nekopi ye-blockchain, kwaye abaze bacelwe kwinkqubo yokuqinisekisa kunye nenkqubo yokuqinisekisa.

Umxhasi we-SPV unomsebenzi osisiseko: ivumela nawuphi na umsebenzisi ukuba ajonge ukuba ngaba intengiselwano ethile ibandakanyiwe kwibhloko okanye hayi, ngaphandle kokukhuphela yonke idatha yebhloko. Benza njani? Bacela ulwazi oluthile kwezinye iindawo ezipheleleyo (iindawo eziphezulu). Abathengi abancinci basebenza njenge Indawo yokuphela konxibelelwano kwaye zisetyenziswa zizipaji ezahlukeneyo (iipaji) ukugcina i-cryptocurrensets.

Abaxhasi vs iiNdawo zeMigodi

Ngokubalulekileyo, ukugcina i-node epheleleyo kwahluke kakhulu ekugcineni i-node yemigodi epheleleyo. Ngelixa abasebenzi-mgodini kufuneka batyale imali kunye nezixhobo ukuthenga kunye nokusebenzisa izixhobo ezibiza kakhulu kunye nesoftware (khumbula ukuba bangakanani abantu abakhalazayo ngombane osetyenziselwa imigodi yeetcoins), nabani na unokugcina indawo eqinisekisiweyo. Ewe kunjalo, ngaphandle kwesixokelelwano esipheleleyo sokusebenza, umgodi akanakwenza nantoni na: ngaphambi kokuzama ukwenza ibhloko, umntu osebenza emgodini kufuneka afumane i-ok kwi-node epheleleyo, eqinisekisa kwaye iqinisekise ukuthengiselana okusalindelweyo. Ke ummbizi unokwenza ibhlokhi efake isicelo sokubamba olo lwazi (kunye neqela lentengiselwano) kwaye azame ukwemba ibhloko. Nantsi i-blockchain imalunga nokuhlaziywa kwakhona: ukuba umgodi uyakwazi ukufumana isisombululo esifanelekileyo sebhloko ngoku unokudluliselwa kuyo yonke i-blockchain kunye neendawo ezipheleleyo zokuqinisekisa ukusebenza kwayo. Ekugqibeleni, imigaqo yemvume igqityiwe kwaye iqinisekisiwe ngothungelwano olusasaziweyo lwe ukungqinisisa iindawo, ayiveli emgodini.

isiphelo

Iindawo zeBitcoin zinxibelelana nabanye ngeP2P Bitcoin yenethiwekhi kwaye ngokuqhakamshelana rhoqo, baqinisekisa ukuthembeka kwenkqubo. Ungathini ukuba kukho iqhina elingaziphathi kakuhle, elinganyanisekanga, elinobubi, elizama ukuhambisa ulwazi oluphosakeleyo? Kwi-blockchains, ulwazi luhamba: loo node iyaziwa ngokukhawuleza ngamanqanaba athembekileyo kwaye ikhutshwe ngokukhawuleza kwinethiwekhi.

Yimalini endinokuyifumana ngokugcina node epheleleyo yokuqinisekisa? '?

Ikazoo! Akukho mbuyekezo yezoqoqosho enikezelwayo: kugqitywa kukuthenjwa ngabasebenzisi, kubonelela ngoxolo lwengqondo, ukhuseleko, imfihlo kubasebenzisi. Iindawo ezipheleleyo ngabapempe bomdlalo wokwenene: baqinisekisa ukuba imigaqo iyalandelwa. Bakhusela i-blockchain kuhlaselo lobuqhetseba (njenge Ukuchitha kabini) kwaye akukho mfuneko yokuba bathembele komnye umntu.
