Kunzwa izwi 'Blockchain' uyo asingazive macryptocurrencies anogona kuzvifananidza nemabhuroko emuviri kana cheni nepo vamwe veavo vane ruzivo rushoma nezve cryptos vanganzwa kuti zvakafanana neBitcoin.
Maererano Blockchain Research Institute, blockchain ndiyo yechipiri internet. Zvinonzi internet yekutanga, iyo yatinayo ikozvino, ndiyo 'internet yeruzivo' nepo blockchain, yechipiri internet, ndiyo 'internet yekukosha.'
Sezvineiwo, hapana anoziva munhu kana vanhu vakagadzira iyo blockchain. Nepo chikwereti cheBitcoin neBlockchain chakapihwa Satoshi Nakamoto, zita racho rinongori manyepo.
Chii chinonzi blockchain tekinoroji?
Iyo blockchain ibhuku redhijitari remarekodhi akarongwa mumabhiti edata anonzi Mablocks, anogona kumiririrwa muchimiro chemidziyo yedhijitari.
Mukutaura kwakapfava, itiweki yemakomputa anogovera nhoroondo yakafanana yekutengeserana, nenzira yekuti rondedzero yekutengeserana inobatwa pakombuta yega yega, uye kutengeserana kwega kwega kunopihwa mvumo nekombuta yega yega kuitira kuti inogara ichizvivandudza pachayo.
Iyo blockchain ndiyo tekinoroji inopa masimba emari dzemari seBitcoin, Ethereum, nevamwe.
Iyo network ye 'node' inogadzira iyo blockchain. A Node komputa yakabatana kune blockchain network ichishandisa mutengi anoita basa rekusimbisa kutengeserana.
Nhoroondo ye blockchain uye bitcoin
Blockchain yakatanga kufungidzirwa naSatoshi Nakamoto muna 2008 (Wikipedia) Gore rakatevera, yakaurayiwa se chikamu chikuru che bitcoin, kwaishandiswa segwaro reruzhinji kune ese matransaction pane network. Izwi rekuti block uye cheni rakashandiswa zvakasiyana mubasa rekutanga raSatoshi Nakamoto asi, pakazosvika 2016, vakazoshandisa izwi rimwechete, blockchain.
Kuburikidza nekushandiswa kwe blockchain tekinoroji kune bitcoin, yakava iyo yekutanga cryptocurrency kugadzirisa dambudziko rekushandisa kaviri pasina kudiwa kwechiremera chinovimbwa sewechitatu mukutengeserana.
Muna Nyamavhuvhu 2014, iyo bitcoin blockchain faira ine zvese zvekutengesa zvakaitika pane network yaive 20GB (gigabyte), uye muna Ndira 2017, yakakura kusvika 100GB muhukuru.
Iyo blockchain inoshanda sei?
Iyo blockchain yakafanana nespredishiti inodhindwa kane zviuru nezviuru pamanetiweki emakomputa, uye inovandudzwa nguva dzose.
Zvine musoro kuti nzira chete yekudzivirira gwaro rinokosha pakati pemapato maviri kuvimba nechiremera chepakati sebhangi kana kambani yekadhi rechikwereti. Nekudaro, blockchain ine tekinoroji inochengetedza gwaro rakadaro zvakachengeteka nekudaro ichibvisa chiremera chepakati kuburikidza nehurongwa hunokurudzira 'vacheri' kuita izvo zvakanaka.
Vacheri vanochengeta zvinyorwa zvese zvekutengeserana zvakaitika mu cryptocurrency network mukati menguva yakatarwa. Vacheri vanobva vapinda mune imwe mhando yemakwikwi ayo anokunda anoonekwa kuburikidza nemamiriro maviri.
i. Mugodhi ane yakajairika vhezheni ye blockchain.
ii. Wekutanga mugodhi anonyatsogadzirisa yakaoma yemasvomhu puzzle.
Mugodhi anobuda achikunda anogadzira bhuroka nyowani ine zvese zvitsva zvekutengesa. Vamwe vashandi vemigodhi, vanovandudza mafaira avo e blockchain kune yazvino vhezheni yakagadzirwa neanokunda uye anokunda anobva awana mubairo.
Zvakanakira zve blockchain tekinoroji
Smart zvibvumirano.
Izvi zvibvumirano zveotomatiki uye zviri kuzviuraya. Hazvidi mumwe wechitatu semabhangi kuti ashande. Zvibvumirano zvinozviita pachavo mushure mekunge zvibvumirano zvese zvasangana.
Chengetedzo.
Blockchain inoshandisa cryptography uye encodes kutengeserana nenzira yekuti munhu haakwanise kuona chaizvo maitirwo akaitwa asi anozoziva chete kuti kutengeserana kwapera.
Kuwedzera kushanda nesimba uye nekukurumidza.
Kuburikidza neiyo otomatiki yemaitiro anosanganisirwa mu blockchain kupesana neyechinyakare nzira yekuchengeta madhairekitori ekutengeserana, kutengeserana kunowedzera nekukurumidza uye kushanda nesimba.
Yakadzikira mitengo.
Kune bhizinesi rega rega, kuderedza mutengo kwakakosha. Ne blockchain, haudi vazhinji vechitatu mapato kuita vimbiso nekuti hazvina basa kana iwe uchigona kuvimba nemumwe wako wekutengesa, pane kudaro, iwe unongofanira kuvimba nedata riri pa blockchain.
Zvakaipa zve blockchain tekinoroji
Wasteful.
Yese node inomhanyisa blockchain kuitira kuchengetedza kubvumirana mhiri kwe blockchain. Izvi zvinopa yakanyanyisa mwero wekushivirira kukanganisa, zero downtime uye zvakare inoita kuti data rese rakachengetwa pa blockchain risachinjike zvachose. Apo node imwe neimwe inodzokorora basa, inopisa nguva yakawanda uye magetsi.
Network/kumhanya mutengo.
Tekinoroji yeBlockchain inoda node kuti imhanye, asi senge network zhinji dziri nyowani, dzinoshaya nhamba yemanodhi inogonesa kushandiswa kwakapararira.
Kukura kweBlock.
Kutengeserana kwega kwega kwakawedzerwa kumaketani kunowedzera saizi yedhatabhesi, sezvo node imwe neimwe inofanirwa kuchengetedza ketani kuitira kuti imhanye.
Hard and soft Forks.
Kana node dzichichinja software yavo, pane katsika kekuti "forogo" mucheni. Nodes inoshandisa software itsva haigamuchire kutengeserana kwakafanana semanodhi anoshanda yekare.
mhedziso
Iyo blockchain idhatabhesi yakagoverwa inochengeta iri kuwedzera ledger uye marekodhi. Iyo leja yakavharidzirwa uye inoidzivirira zvakachengeteka kubva kune chero nzira yekukanganisa, kudzokorora, uye kudzima.
Kukosha kweiyo blockchain tekinoroji kushanda sesimba reiyo cryptocurrencies haigone kusimbiswa zvakanyanya nekuti ine zvakawanda zvakanakira uye zvinozongoita nani mune ramangwana.
Musanganiswa wekutengeserana, kuendesa dhata mudhadha uye mabhuraki zvinopa mikana mikuru yemakristptocurrencies! Asi fungidzira chii? Blockchain inogona zvakare kushandiswa mune chero indasitiri parutivi cryptocurrencies, kubva muchitoro chegirosari kuenda kumasarudzo ekugadzira uye kugovera kofi. Chero bedzi paine data yekuchengetedza, iyo blockchain inobatsira.
