Peb xav txog kev ua ib tug tham tsis tas uas muaj rau koj lub txhab nyiaj, los yog lwm cov cai influential thib. Nws ua ib tug loj 'aw' hauv koj lub ntsej muag, kuv paub. Tab sis npog, tseem tau tseeb tias tsawg tus neeg paub txog lub ntiaj teb no tej yam yees siv lub blockchain tshuab. Tab sis tsis txhob poob siab, siv tshuab no tau stepped xis ntawm lub 'buzzword' nyob ntev mus txog rau txhua txhua doorstep nyob hauv ntiaj teb no. Tseem tuav; peb twb yuav tshawb ' tus biggest innovation nyob rau hauv lub computer science' rau tib neeg.
Blockchain yog dab tsi?
Thawj taub Blockchain yog cov brainchild Satoshi Nakamoto thiab programmers nyob hauv nws pawg 2008, thiab lub tshuab yog implanted li lub caij tub ntxhais ntawm lub qhov qhib software Bitcoin cryptocurrency hauv 2009.
Technically hais tias, Nws yog ib tug distributed database uas tswj ib puas-loj hlob sau ntaub ntawv, npe hu ua blocks. Os, txhua thaiv twg muaj ib lub sij hawm-stamp thiab yog muaj feem rau ib ntu dhau los. Tab sis, nws yog ib tug sketch ntxhib tab. Lub hom phiaj tseem ceeb ntawm nws yog mus daws cov teebmeem ntawm ob-siv decentralized yam tsis tas inter-mediating kev ntseeg rau lwm tus neeg li nyiaj hauv tuam txhab los yog tsoom fwv siv cov txwm ntawv pov thawj ntawm-hauj lwm.
Ntsiab?
Koj tsis tas yuav mus muab tau koj tej khoom muaj nqi rau ib centralized almighty los yog tsoom fwv influential lawv tiv thaiv kom nws monetizing, kom lawv ua neeg zoo los ntawm koj tus kheej los yog cuam tshuam nrog txhua tus tham koj ua. Yuav tsis muaj los txhob ntshai yam fraudulence, vim tias nws kuj yog ib txoj kev ncaj nrog tus hnov kiag ntawm txoj kev ywj pheej rau koj tej khoom muaj cuab. Nws muaj "lub platform tseeb thiab ntseeg." Wb khawb deep kuj nce mentsis.
Nyob rau hauv cov kev sib tham nrog Lub McKinsey Rik Kirkland, lub Tapscott Group CEO tsis txhob Tapscott elaborates li cas lub qhov qhib distributed database ntawm blockchains no ua tau tsis zoo xwb los ua haujlwm ua ke thiab taug qab txhua txhua txoj kev tham thiab sis uas siv lub xeev-ntawm-tus-daim duab cryptography tab sis mus rau authenticate tus hais sib haum nrog rau txoj kev teeb.
Nyob rau hauv nws phau ntawv Kiv puag ncig Blockchain puag authored nrog nws tus tub Alex Tapscott, Tsis txhob qhia qhov txawv ntawm cov laus tshaj tawm thaum ntxov 1990's nrog rau ntau schemes ib thiab hnub no tus qhib tawm muaj ntau leej ntau qhov uas tus neeg tuas tshwm sim rau lwm txoj cai ua. Yuav tsum assumed raws li tus neeg loj heev, thoob ntiajteb khiav ntawm txhua lub computer txuas rau internet nrog spreadsheet. Tam sim no, Thaum tus neeg tau kev koom tes rau cov coding, txhua tus tseem muaj txoj kev mus saib xyuas lawm cov duab tag nrho rau txhua cov kev tshwm sim soj ntsuam qhov chaw nyob no qhib tawm.
Wb muaj ib qho piv txwv ntawm nyiaj Identify. Hais, koj yuav tsum rho $100 rau ib tug neeg. Koj ua tus lw, dua, koj xa ntawv qub rau lwm tus. Tam sim no, Thaum koj yuav siv tau cov nyiaj them poob haujlwm uas siv Bitcoin crypto-txiaj, Nws yog authenticated los ntawm network o thiab kaw rau cov pej xeem ledger ntawm blockchain. (Ntawm no qhia qhov no tias tus biggest blockchain tshuab bitcoin yog ntawv pov thawj raws li thawj decentralized cov txiaj txij thaum nws eliminates qhov yuav tsum tau rau hab txhawb kev khiav xwb.) Tam sim no muaj ntau leej tujtaws xyuas thiab sau seb txhua tshiab lw broadcasting rau ib pab pawg neeg tshiab hu ua ib ntu yooj.
Os, txhua miner aims rau tus thawj foundations mus nrhiav qhov tseeb. Ib zaug los, nws yuav cov pov thawj ntawm lub zej zog tag nrho siv no qhib tau qhov twg los. Tus nqi zog rau cov kev pab cuam no tsuas yog yuav dlaws teeb meem kev xaam phaaj txoj yog kom tau tej nyiaj uas yog ib co bitcoin rau txuas. Os, tus lw nqi yog nyob ntawm yeem, qhov twg cov yooj prioritize le mas them cov nqi tes thiab cov unsent inputs cov muas.
Cov nqi yog nyob ntawm seb qhov cia me me thiab tsawg inputs rau txheej txheem txoj lw. Tam sim no rau hack tus lw los yog nyiaj txoj kev xa cov ntaub ntawv cov qub rau lwm tus neeg yog suab yeej ua raws li koj yuav tsum rau hack ntawd 10-feeb thaiv. Os, txhua thaiv twg muaj ib cryptographic hash ntawm nws ib teev thaum uas siv cov SAB.-256 hashing algorithm, uas connects nws kom nws thaiv yav dhau los thiab lub dhau los ntawd thiab thiaj mus.
Yog li, nws khwv tau lub npe raws li tus blockchain uas txuas nrog lub tsheej lab ntawm cov computer systems. Yog yuav kuas nyuas siv zug ib kev dag, nws yuav tsum muab qhov chaw hauv qab lub taub ntswg los ntawm keeb kwm kev lag luam tag nrho. Ntawd puas tau? Mas nws yeej tsis muaj.
Cov xwm txheej tam sim no ntawm Blockchain:
Lub blockchain tshuab los yog bitcoin tseem tsis txhob conquering cov tug industries nyiaj xwb. Nws tseem mus rau lwm cov placebo exchangeable, cov kev pab los yog khoom uas vim nws muaj peev xwm yuav sau cov ntaub ntawv rau tej ntaub ntawv kom xyaum txhais tau hais tias yog ib tug neeg sib raws li txoj cai uas ib tug neeg, tus paub txog owning tej khoom, ib qhov txuas nrog rau kev pab los yog lwm yam xov xwm uas koj xav tau ntawm cov hwjchim. Internet ntawm tej yam muaj nyob blockchain lawv hais haum siab uas yog, qhov twg tooj uncountable muas real-time saib qhov chaw ntawm tej, Nws yog ib qho tsis yooj yim sua kom tus ntug dej kom muaj.
Nyob rau lub ob hlis ntuj 2015, muaj 100,000 tub txawj tub ntse thiab cov uas txais cov bitcoin ua tus qauv ntawm cov nyiaj them poob haujlwm. Thiab daim ntawv ntawm Cambridge tsev kawm ntawv nyob rau hauv daim ntawv ntsuam xyuas 2017 proclaimed kom muaj nuj nqis ntawm cov neeg nws muaj txiaj crypto hnab li 2.9 mus 5.8 plhom thoob ntiaj teb, cov uas feem coob ntawm cov tshuab cov bitcoin. To taub cov ntseeg implanted ntawm no siv tshuab revolutionary niaj hnub, koj yuav tau saib ntawm lub sab duab uas yog tseem xam zog qhov uas Google mas kwv yees xwb tus 5% ntawm lub xam hwj chim los rau bitcoin blockchain spreaded blockchain.
No qhib qhov software muaj lub potentiality los rearrange lub kaw lus tag nrho ntawm txhua qhov kev lag luam hauv lub prospect ntawm neutralization qhov chaw uas sawv daws plays lub luag hauj lwm sib npaug zos koom kev nyias muaj nyias tus nqi los ntawm koj qhov cuab tam ntawd cov lawv ua.
Zoo li qub tau ua haujlwm rau Imogen Heap, Cov paub zoo tias singer-songwriter hauv lub tebchaws United Kingdom, leej twg yog ib tug nyob hauv pab cov creators ntawm Mycelia. Collaborated nrog cov blockchain tsim tawm lub tshuab kev pom zoo, thiab nws muab lo nws zaj kwv txhiaj rau hauv internet uas tau kev pab los ntawm Ethereum platform ntawm blockchain.
Tso cai dua thiab Permissioned, los yog lwm yam blockchains:
Bitcoin thiab lwm cov placebo crypto siv tso cai tsis muaj blockchains qhib rau pej xeem ledger. Nyob rau lub Cuaj hlis 2016 bitcoin muaj capitalized rau ntau tshaj yog feem kev ua lag luam hauv lub keeb kwm blockchain. Cov yees qhib muaj ruaj los ntawm cov qauv ntawv pov thawj ntawm-hauj lwm. Bitcoin, qhov no, nyob Hashcash learn tsim tau Adam Back hauv lub Kwvyees li xyoo 1990.
Tab sis cov tuam txhab nyiaj txiag uas muag xav lwm yam los yog permissioned blockchains hloov decentralized, qhib qhov chaw. Cov yees kom tus ntsim thiab nrog lawv qhib qhov twg uas tswj neeg nyob hauv txoj kev pom zoo xaiv. Lub sij hawm New York muaj qhia cov ntsuam ntawm ntau cov koom haum rau neb ob leeg 2016 thiab 2017 nyob rau kev siv lawv blockchains lwm yam neeg sab nraud ntawm lub tshuab pej xeem.
Disadvantages:
Txhua lub caij nyoog los nrog rau tej lus nug yuav muab coj los teb thiab cov kiv puag ncig blockchain yog tsis kos los uas. Nyob rau hauv Computerworld, Nikolai Hampton muaj pinpointed qhov no rau tsoom blockchain li: “Yuav kuj tsis muaj tau tus ' 51 feem pua ' nres rau ib qhov blockchain, ua lub chaw blockchain (ntxim) twb ntawm lwm yam uas 100 feem pua ntawm tag nrho thaiv creation III.. Yog koj yuav ua mob los puas tus blockchain creation yam rau ib tsoom neeg neeg rau zaub mov, koj yuav siv los tswj 100 feem pua ntawm lawv network thiab hloov muas li koj xav.” Kev bitcoin, nws ntxiv, "lub bitcoin blockchain yog kev tiv thaiv los ntawm lub dag zog loj heev neeg tsuas. Yog nws tsis pom hais tias tej blockchain lwm yam yuav ua kom pov hwm cov ntaub ntawv uas siv cov gigawatts uas xam muaj hwj huam — yog sij hawm haus mas thiab nws kim heev.” Tseem, ' Tsis pub dhau ib blockchain lwm yam muaj los tsis muaj ' hnub nyoog yog'; yog tsis ua kom muaj siab siv zog ntau dua los yog nrhiav tau blocks sai dua competitors. Qhov no txhais tau tias ntau dlaws in-house blockchain yuav tsis muaj dab tsi ntau tshaj li cumbersome databases.”
Tsab ntawv thiab lub neej yav tom ntej:
Tsis txhob muaj tej teeb meem rau kev ua hauj lwm rau, peb tau tam sim no siab rau thaj tsam ntawm daim ntaub ntawv ❑ ❑ blockchain loj heev rau peb lub neej.
- Daim ntawv thov biggest blockchain muaj cryptocurrencies li bitcoin, blackcoin, Khiav ceev thiab Nxt thiab cov blockchain platforms mus yuav nyiam tag Factom txog npe distributed, Gems rau decentralized messaging, Maidsafe rau cov kev siv decentralized, yam.

- SMART-sib cog lus yuav tsim blockchain uas yog cov los mas executable tsis muaj kev sis tib neeg vim yog.
- Lwm blockchains los yog altchains tseem nyob rau lub tshuab bitcoin vim yog tswvyim los yog coding. Nyob rau hauv qhov uas tsis yog-cryptocurrency designs, LaZooz raws li decentralized caij sib koom vib this, Synereo tej hauj lwm hauv synchronous thiab asynchronous sib, Steemit combines ib qhov chaw blogging nrog cryptocurrency, thiab daim ntawv nrog rau ntau ntxiv.
- Nyob rau hauv tej sectors, Deloitte thiab ConsenSys los nyob rau hauv 2016 rau lub sij hawm thaum cov hu ua Project ConsenSys; Microsoft quas Studio Yog tas cov nyob rau ntawm Ethereum Solidity lus rau daim ntawv thov developers; Disney tau tsim nyob rau hauv lub tshuab blockchain Dragonchain.
Xaus:
Daim ntawv no tsis yog kom tau. Ntxhias, koj yuav tsis txiav txim rau lub caij nyoog tej zaum thiab tej yam tom ntej budding technology zoo ib yam li blockchain. Tab sis npog, ib yam yog tseeb uas cov blockchain, yog lub caij txom thiab tiag, qhov kev siv cov kev blockchain technology no yuav txiav txim nws yav tom ntej nrog rau lub ntiaj teb no tej yam.
