Blockchain yog pej xeem cov ntaub ntawv ntawm kev hloov pauv hauv Bitcoin system. Nrog nws cov kev pab, txhua tus neeg siv tuaj yeem paub ntau npaum li cas Bitcoin nyob ntawm qhov chaw nyob hauv ib lub sijhawm. Nyeem ntxiv txog dab tsi Blockchain technology yog.

Purpose

Blockchain tuaj yeem siv tau txhua qhov chaw muaj kev tsis ntseeg siab ntawm cov neeg koom. Piv txwv li, hauv kev muag khoom lag luam yeej ib txwm muaj kev pheej hmoo uas tus neeg muag khoom yuav tsis tau txais cov nyiaj, thiab tus neeg yuav khoom yuav tsis tau txais kev pabcuam / khoom. Siv lub kaw lus, koj tuaj yeem tshawb xyuas qhov tseeb ntawm cov ntaub ntawv, khoom, kev pabcuam lossis tuam txhab.

Blockchain thev naus laus zis piav qhia

Blockchain yog ib hom kev sau nyiaj khaws cia uas khaws cov ntaub ntawv hais txog cov xwm txheej ntawm lub neej tiag tiag. Tab sis nyob rau tib lub sij hawm, nws txawv ntawm analogues nyob rau hauv lub siab ntawm kev qhib siab thiab kev ntseeg tau. Nws tsis tuaj yeem raug faked lossis tshem tawm, tab sis tag nrho cov xwm txheej kaw tuaj yeem txheeb xyuas tau. Cia wb mus saib qhov tseem ceeb ntawm kev siv tshuab.

Blockchain yog ib txoj hauv kev sau tag nrho cov ntaub ntawv pej xeem (kev sib cog lus, kev cog lus, kev cog lus). Nws peculiarity yog tiascov ntaub ntawv ntawm txhua qhov kev hloov pauv tsis yog khaws cia rau hauv ib qho chaw, tab sis tawg mus thoob ntau txhiab lub khoos phis tawj. Yog li txhua tus neeg siv tuaj yeem nkag mus rau cov ntsiab lus.

Txhua cov ntaub ntawv tau muab ua ke siv lej algorithms rau hauv cov blocks, thiab tom kawg tsim cov saw hlau. Txhua lub block muaj qhov hash ntawm yav dhau los. Cov saw no pib los ntawm thawj qhov thaiv hauv qhov system thiab siv tau mus txog qhov kawg. Kev kho cov ntaub ntawv uas nyob online ntev ntev yog qhov ua tsis tau. Tag nrho cov blocks yuav tsum tau rov sau dua. Qhov ntev ntawm cov saw hlau yog txiav txim los ntawm qhov nyuaj, tsis yog tus naj npawb ntawm cov khoom.

Txoj kev hashing tsis tso cov ncauj lus kom ntxaws txog kev hloov pauv, tab sis tsuas yog lees paub qhov tseeb ntawm nws qhov muaj nyob. Thaum cov ntaub ntawv hloov tshiab, nws hloov tsis tau. Koj tsuas tuaj yeem ntxiv cov ntaub ntawv tshiab.

txiaj ntsig

Qhov kev faib tawm ntawm cov ntaub ntawv ua rau nws tiv taus kev tawm tsam hacker thiab ua kom cov ntaub ntawv tsis pub lwm tus paub. Cov ntaub ntawv los ntawm hash tsis tuaj yeem luam tawm. Tab sis txawm hais tias cov ntaub ntawv hloov pauv ntawm qee theem, nws yuav tsis phim cov kos npe digital. Lub kaw lus yuav muab qhov yuam kev tam sim.

Scope of application

Blockchain yog kev tiv thaiv tub sab nyiag. Yog tias cov ntaub ntawv qiv nyiaj tau khaws cia hauv qhov system, kev qiv nyiaj dag, kev qiv nyiaj qiv nyiaj, thiab qiv tsheb yuav raug tiv thaiv. Hauv qee lub tebchaws, kev taw qhia txog kev siv rau cov hom phiaj no twb tau txiav txim siab.

Hnub no, Blockchain thev naus laus zis yog siv feem ntau hauv cryptocurrencies (bitcoin, litecoin,nxt). Hauv cov piv txwv no, tag nrho lub zog ntawm lub kaw lus thiab nws cov kev txwv tau pom tseeb. Hauv qee lub tebchaws, cov txheej txheem siv los kho cov cai thaum yuav cov duab kos duab.

Twb 42 ntawm lub ntiaj teb cov tsev txhab nyiaj loj tshaj plaws (tshwj xeeb, Bank of America, Morgan Stanley thiab lwm tus) tau tsim lub koom haum R3. Lawv tab tom txhim kho cov kev taw qhia tshiab Blockchain (txheej txheem rau kev them nyiaj mobile thiab lwm yam nyiaj txiag ntws). Lub tuam txhab zoo sib xws DAM twb tau tsim los ntawm 13 lub koom haum (ABN AMRO, BNP Paribas, JPMorgan, thiab lwm yam). Nws kuj tseem koom nrog hauv kev siv lub platform hauv kev lag luam nyiaj txiag. R3 twb tau sim nrog kev sib pauv ntawm bitcoins los ntawm thoob ntiaj teb network, tsis muaj kev koom tes ntawm peb tog.

Nyob rau xyoo 2015, Goldman Sachs thiab IDG Capital Partners tau nqis peev $ 50 lab hauv Circle Internet Nyiaj Txiag, kev pib ua haujlwm tsom rau kev siv Blockchain los txhim kho qhov zoo ntawm Bitcoin thiab USD hloov pauv.

Blockchain thev naus laus zis tau siv los ntawm Everledger los tsim kom muaj kev lav phib xaub rau cov lag luam pob zeb diamond mining. Cov neeg yuav khoom yuav tuaj yeem kawm keeb kwm ntawm txhua lub pob zeb diamond. Rau lub hom phiaj no, Everledger tau nqis peev $ 850 lab hauv cov ntaub ntawv.

Estonian tuam txhab Guartime, uas yog nyob rau hauv pem hauv ntej ntawm lub teb chaws cov ntaub ntawv cov ntaub ntawv ua, tau tsim ib tug Keyless Kos npe Infrastructure ua rau bitcoins. Ua tsaug rau qhov kev tsim kho tshiab no, tsoomfwv tuaj yeem tiv thaiv cov ntaub ntawv ntawm lub tebchaws cov neeg nyob hauv 1000 kev pabcuam hauv Internet.

Qhov ntawd yog, qhov kev thov rau kev siv thev naus laus zis tau loj hlob tas li. Tseem tsis tau muaj kev ua haujlwm zoo li no hauv tebchaws Russia.

qhov kev thov no tuaj qhov twg?

Nyob hauv tuam txhab nyiaj, txhua qhov kev lag luam raug saib xyuas los ntawm ib lub tshuab muaj zog. Kev siv ntau lub khoos phis tawj yog kev siv nyiaj ntau. Blockchain system, cov lus piav qhia thev naus laus zis uas tau nthuav tawm saum toj no, ua rau nws muaj peev xwm tshem tawm cov neeg nruab nrab, kev tuav cov ntaub ntawv, ua kom ceev, thiab txo cov nqi. Qhib nkag mus rau cov ntaub ntawv tseem ceeb rau tus tswj hwm. Lub xeev yuav tuaj yeem sau se tau yooj yim dua. Yog tias cov tsev txhab nyiaj ua kom cov txheej txheem sib pauv thiab txo cov nqi, qhov no yuav ua rau cov kev pabcuam zoo dua thiab pheej yig dua. Kev xa mus thoob ntiaj teb yuav sai sai.

Lwm qhov project

Muaj qee qhov kev pib nthuav dav ntxiv siv Blockchain:

• tØ - CB trading platform;
• BoardRoom - kev tswj hwm kev lag luam;
• UjoMusic - kos duab txoj cai tswj hwm;
• Provenance - keeb kwm tswj qhov system;
• BitProof - daim ntawv pov thawj thev naus laus zis;
• EverLedger yog lub pob zeb diamond nrhiav qhov system.

No tsis yog tag nrho cov npe ntawm kev pib siv Blockchain thiab Bitshares technologies.

Qiwi Siv Blockchain

Hauv Qiwi system, cov ntaub ntawv yav dhau los tau xa mus rau hauv nruab nrab. Qhov no ua rau muaj kev thauj khoom siab thiab ntau qhov ua tsis tiav. Kev taw qhia ntawm Blockchain yuav txhim kho kev ruaj ntseg thiab txo cov nqi ua haujlwm.

Lub hnab nyiaj ntawm Qiwi cov nyiaj them poob haujlwm muaj "cov saw hlau thaiv". Lub checksum ntawm yav dhau los ib qho yog embedded nyob rau hauv txhua qhov txuas tom ntej. Yog li ntawd, cov blocks tsimib txoj saw uas tsis tuaj yeem hloov lossis tshem tawm ib yam dab tsi.

Txoj kev them nyiaj tom ntej uas Blockchain yuav raug coj los ua yog WebMoney hnab nyiaj. Nws npaj siab tias kev txheeb xyuas cov neeg siv khoom yuav tshwm sim ntawm blockchain. Qhov no yuav tso cai rau cov tswv cuab tshiab ntawm lub kaw lus tuaj yeem txheeb xyuas lawv tus kheej yam tsis tau mus ntsib lub chaw ua haujlwm.

Sberbank siv Blockchain

Lub txhab nyiaj loj tshaj plaws hauv tebchaws Russia npaj siab koom nrog R3 koom ua ke los koom ua ke cov kev pabcuam raws li kev siv thev naus laus zis crypto. Qhov no yuav nce qib ntawm kev ruaj ntseg kev lag luam thiab txo kev cia siab rau SWIFT system yav tom ntej. Cov txheej txheem kev tiv thaiv kev tiv thaiv kab ke xyaum tsis suav nrog qhov ua tau ntawm cov ntaub ntawv spoofing. Nyob rau tib lub sijhawm, cov ntaub ntawv yog tus yam ntxwv los ntawm theem siab ntawm kev faib tawm thiab qhib cov ntaub ntawv.

Sberbank npaj yuav siv cov txheej txheem tshiab los hloov pauv ntawm cov chaw pabcuam thiab lwm lub tsev txhab nyiaj. Peb tsis tau tham txog kev qhia txog peb tus kheej cryptocurrency. Tsis tas li ntawd, Central Bank muaj qhov tsis zoo rau tag nrho cov nyiaj surrogate.

Txoj kev xav, Blockchain thev naus laus zis tuaj yeem txo qee qhov kev pheej hmoo ntawm nom tswv. Thaum cov kev rau txim tau pib ua ntej, cov tsev txhab nyiaj tau ntshai tias lawv tuaj yeem raug txiav tawm ntawm SWIFT. Kev siv Blockchain nce kev ruaj ntseg ntawm kev ua haujlwm, vim tias lub kaw lus tsis muaj ib tus neeg tswj hwm.

Obstacles

Kev taw qhia ntawm Blockchain cuam tshuam nrog kev tsis paub tseeb ntawm kev siv lub kaw lus. Cov neeg ua lag luam tau pom Russia ua tus xa khoom ntawm cov thawj coj thiab cov neeg ua haujlwm. Raws li kev soj ntsuam kev xav, tsuas yog 1 ntawm 5 tus neeg Lavxias paub txog qhov muaj nyob ntawm Bitcoin. Ntawm no, ob feem pebtib neeg xav txog cryptocurrencies ib yam dab tsi txhaum cai. Cov teeb meem no twb tau hais tawm hauv lwm lub tebchaws

Blockchain thev naus laus zis: "rau dummies"

Startup Blockstrap yuav tuav cov rooj sib tham pub dawb blockchain rau cov neeg nyob hauv Turkey, Lub Tebchaws Yelemees, Australia, Czech koom pheej thiab Askiv. Hoob no yog tsim los rau cov neeg uas xav paub ntau ntxiv txog kev sau npe rau pej xeem, cov tsim software, cov neeg xav paub txog kev lag luam digital.

Raws li ib feem ntawm qhov kev zov me nyuam, cov tub ntxhais kawm yuav kawm txog kev faib khoom, kev siv tshuab hluav taws xob thiab kawm paub tsim lawv tus kheej daim ntawv thov. Cov neeg tuaj koom tsuas yog yuav tsum muaj kev paub txog kev tsim cov vev xaib thiab tsim cov ntawv thov dav dav.

Cryptographic keys

Cryptographic keys yog lub hauv paus ntawm Blockchain thev naus laus zis raws li. Nws yog dab tsi? Tus yuam sij yog tus lej ntev heev. Piv txwv li, qhov no: 1731695423709850868. Nws tsuas tuaj yeem decrypted los ntawm cov txheej txheem hash. Tsuas yog ib tus yuam sij tsim nyog rau txhua qhov nkag. Lwm qhov tseem ceeb: thaum hloov yam tsawg kawg ib lub hauv paus, cov lej hloov pauv tag nrho.

Network

Cov ntaub ntawv hais txog kev thaiv yog khaws cia ntawm cov neeg siv lub khoos phis tawj. Tag nrho cov ntawm lawv yog sib npaug. Thaum nyob rau hauv lub network, tus neeg siv txuas mus rau tag nrho lwm cov computers. Nws yog ib qho tseem ceeb uas lub network no tsis khi rau thaj chaw.

Tom qab tau txais cov ntaub ntawv, tus neeg siv tshuaj xyuas nws thiab, kom paub tseeb tias nws yog lawm, txuag nws hauv lub network, thiab tom qab ntawd hloov mus ntxiv. Cov neeg koom nrog tau muab faib ua pawg: cov neeg siv uas tsim cov ntaub ntawv tshiab, thiab cov miners uas tsimblocks.

Cov ntaub ntawv raug xa tawm thoob plaws lub network hauv txoj kev no: "tus neeg siv nrog tus yuam sij B hloov 300 nyiaj txiag rau tus neeg siv nrog tus yuam sij A". Cov ntaub ntawv qhib, tab sis tib lub sijhawm encrypted. Paub txog tus yuam sij ntawm lub tsheb, koj tuaj yeem tshawb xyuas seb nws puas tau cog lus, tab sis koj yuav nrhiav tsis tau lub npe ntawm tus tswv. Ib yam ntawm no.

Cov Miners sau cov ntaub ntawv, tom qab ntawd lawv tau txheeb xyuas thiab sau rau hauv cov blocks faib thoob lub network. Cov neeg siv ib txwm tau nkag mus rau cov blocks no txhawm rau khaws cia rau lawv tus kheej, tsim cov ntaub ntawv raug thiab tshawb xyuas lwm tus.

Thaum qhov kev nkag tsis tau sau npe, nws suav tias yog qhov tsis raug. Tus neeg siv yuav siv nws ntawm nws tus kheej txaus ntshai. Qhov kev nkag no tuaj yeem raug tshem tawm txhua lub sijhawm yog tias pom tias yog cuav.

Key mining

Ib tus miner yog tus neeg siv uas tsim cov blocks tshiab. Nws sau cov ntaub ntawv los ntawm lub network, tsim cov header, thiab tsim ib qho tseem ceeb. Xav txog ib qho piv txwv luv.

Xav tias tom qab thawj qhov kev xam pom tus yuam sij zoo li: "311630826946518243738". Raws li cov cai ntawm lub system, nws yuav tsum pib nrog xoom. Koj yuav tsum hloov cov ntaub ntawv qub. Rau cov hom phiaj no, qhov nonce teb yog muab nyob rau hauv lub block header. Tom qab kev hloov kho, nws tus nqi hloov pauv ntawm 0 mus rau 1. Kev suav rov qab yuav tshwm sim ob peb lab zaug kom txog rau thaum tus yuam sij tsim tau raws li qhov yuav tsum tau ua. Tsuas yog tom qab ntawd, cov block tsim yuav raug xa mus rau lwm tus neeg siv Blockchain. Cov lus piav qhia ntawm thev naus laus zis yog qhov yooj yim heev, tab sis tso cai rau koj los qhia cov ntsiab lus ntawm qhov system.

Kev ua kom yuam kev tsuas yog qhov ntawdqhov tshwm sim ntawm kev nrhiav tus yuam sij yog ib txwm zoo ib yam. Ntawd yog, nws tsis tuaj yeem yuav. Txhua lub block tsuas muaj ib tus yuam sij xwb. Nws yuav tsum raug pom. Qhov no yog qhov miners ua. Lawv tau them nyiaj rau lawv txoj haujlwm. Cov txheej txheem tsim cov yuam sij, ntawm ib sab, ua haujlwm nyuaj, thiab ntawm qhov tod tes, nws ua rau kev sim tsim cov ntawv cuav yuav luag tsis yooj yim sua.

Cov lus qhia rau cov pib tshiab

• Txawm hais tias muaj peev xwm loj ntawm cov thev naus laus zis, koj yuav tsum tsis txhob siv zog khi rau txhua qhov Blockchain. Lub log thib tsib tseem tsis tau pab leej twg li.
• Tsis tas yuav tsim "koj" Blockchain. Nws yog qhov zoo dua los hloov cov tswv yim tam sim no rau qhov xav tau ntawm koj qhov project.
• Yog tias koj txiav txim siab siv Blockchain, ces koj yuav tsum tsom mus rau tag nrho lub ntiaj teb ib zaug. Tsuas yog tom qab ntawd tuaj yeem nthuav tawm tag nrho lub peev xwm ntawm qhov project.

Zaj lus

Nyob rau ob peb xyoos, Blockchain thev naus laus zis yuav dhau los ua ib qho chaw hauv Is Taws Nem. Nws txhais li cas? Cov kev pabcuam tsis tu ncua thiab cov khoom tuaj yeem tau txais los ntawm kev siv qhov system: thov daim ntawv hla tebchaws, sau npe tsheb, tau txais qiv nyiaj, yuav daim pib, thiab lwm yam. Ib tus neeg tsuas yog yuav tsum muab tus yuam sij rau lub kaw lus thiaj li tau txais lossis kuaj xyuas cov kev pabcuam. Qhov no yuav txhim kho lub neej zoo.
