Nyob rau hauv ib daim ntawv ntsuam xyuas los ntawm Deloitte ntawm 1,386 tus thawj coj loj, 80% tau teb tias blockchain thev naus laus zis yuav yog qhov tseem ceeb (53%) lossis tseem ceeb (27%) rau lawv lub koom haum txoj kev loj hlob. Ntau li ntawd, 86% ntseeg hais tias blockchain thev naus laus zis yog qhov dav dav thiab yuav ua tiav kev saws me nyuam loj.
Yog li cia peb dhia mus rau hauv nws thiab pom dab tsi yog blockchain, nws ua haujlwm li cas, thiab dab tsi yog qee qhov txiaj ntsig ntawm cov thev naus laus zis no.
1. Blockchain piav qhia
DEF. Raws li lub npe qhia, blockchain yog cov saw hlau ntawm cov blocks uas ua haujlwm raws li daim ntawv teev npe paub hauv ntiaj teb nyiaj txiag raws li cov ntaub ntawv. Ntawm blockchain, cov blocks no txuas ua ke thiab ruaj ntseg los ntawm Cryptography.
Hauv cov ntsiab lus yooj yim, blockchain yog daim ntawv qhia digital.
Txhua cov ntaub ntawv (block) hauv blockchain muaj cov ntawv teev sijhawm, cov ntaub ntawv ntawm kev lag luam blockchain, thiab tus nqi cryptographic hash (kos npe) ntawm qhov thaiv dhau los. Qhov no txhais tau hais tias txhua lub block yog vam khom rau yav dhau los.
Yog li, cov saw hlau.
Leej twg tsim lub blockchain?
Thawj qhov kev ua haujlwm blockchain tau tso tawm xyoo 2009. Tom qab Satoshi Nakamoto luam tawm daim ntawv 'Bitcoin: Ib Peer-to-Peer Electronic Cash System' hauv 2008, nws tau tso Bitcoin software rau xyoo tom ntej.
Tab sis qhov ntawd tsis yog thawj zaug uas lub tswv yim ntawm blockchain tau qhia rau lub ntiaj teb.
Xyoo 1991, Stuart Haber thiab W. Scott Stornetta tau tham txog kev sib txuas cov blocks hauv cov ntaub ntawv txuas ntxiv-tsuas yog hauv lawv daim ntawv kawm, 'Yuav Ua Li Cas Sijhawm-Stamp Daim Ntawv Digital. '
Hom blockchains
Muaj 3 yam tseem ceeb ntawm blockchains:
Pej xeem blockchains
Public blockchains yog cov kev sib txuas lus qhib uas txhua tus tuaj yeem koom ua tus neeg siv, tsim tawm, lossis cov tswv cuab. Txhua qhov kev hloov pauv ntawm pej xeem blockchain tuaj yeem pom thiab tshuaj xyuas los ntawm leej twg.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm pej xeem blockchains yog lawv qhov kev tawm tsam rau censorship.
Lawv tag nrho decentralized, thiab lawv sau cov kev lag luam ntawm ntau lub khoos phis tawj thoob plaws ntiaj teb. Yog li, hloov cov ntaub ntawv ntawm lub network yog tsis yooj yim sua.
Piv txwv ntawm pej xeem blockchains yog Bitcoin, Ethereum, thiab Litecoin.
Private blockchains
Private blockchains, ntawm qhov tod tes, tso kev txwv rau leej twg tuaj yeem koom nrog lawv. Kuj tseem hu ua kev tso cai blockchains, lawv sau lawv cov kev lag luam ntiag tug, ua rau lawv muaj rau cov koom tes hauv network nkaus xwb.
Thaum piv rau pej xeem blockchains, kev tso cai blockchains yog qhov tseem ceeb dua. Lub koom haum khiav cov saw hlau muaj kev tswj hwm tag nrho ntawm leej twg koom nrog nws lub network. Qhov no ua rau tus kheej blockchains zoo tagnrho rau cov lag luam uas xav qhia lawv cov ntaub ntawv tab sis tiv thaiv cov ntaub ntawv rhiab.
Piv txwv ntawm ntiag tug blockchains suav nrog Ripple thiab Hyperledger.
Consortium blockchains
Consortium blockchains, tseem hu ua federated blockchains, muab qhov zoo tshaj plaws ntawm ob lub ntiaj teb. Lawv muaj kev ywj pheej ntau dua li cov blockchains ntiag tug tab sis tso cai tswj hwm cov ntaub ntawv dab tsi yog pej xeem thiab dab tsi tseem ceeb.
Tsis zoo li private blockchains, uas yog tswj los ntawm ib lub tuam txhab, tsoom fwv blockchains yog tswj los ntawm ib tug pre-xaiv pawg ntawm cov koom haum / nodes.
SIDENOTE. Blockchain nodes yog cov khoom siv ( khoos phis tawj, laptops) uas ua raws li cov servers khaws cov ntaub ntawv. Nodes yog ib feem tseem ceeb ntawm blockchain cov txheej txheem.
2. Lub blockchain ua haujlwm li cas?
Txhawm rau piav qhia zoo dua li cas lub kaw lus blockchain ua haujlwm, peb yuav siv Bitcoin blockchain ua piv txwv.
Yuav ua li cas tshiab blocks tsim thiab chained ua ke?
Kuv tau hais ua ntej tias txhua qhov thaiv muaj cov ntaub ntawv ntawm Bitcoin pauv. Txhua qhov thaiv ntawm blockchain tuaj yeem tuav ib puag ncig 1 megabyte cov ntaub ntawv. Tom qab ntawd block tau puv lawm, ib qho thaiv tshiab tau raug tsim.
Cia peb sau qee qhov kev hloov pauv kev xav thiab pom tias qhov thaiv zoo li cas.
Cia peb hais tias Zeus tshuav Odin ib co nyiaj, thiab nws xav them nws rov qab rau hauv Bitcoin. Yog li, Zeus hloov 0.5 BTC rau Odin.
Zoo li tus txiv zoo, Odin txiav txim siab xa ib co hnab tshos nyiaj rau nws cov tub, Loki, thiab Thor.
Loki tau txais 0.1 BTC, tab sis Thor tau txais 0.2 BTC vim Odin ib txwm hlub nws ntau dua.
Qhov no muab peb cov kev lag luam hauv qab no:
T1: Zeus – Odin | 0.5 BTC
T2: Odin – Loki | 0.1 BTC
T3: Odin – Thor | 0.2 BTC
Tam sim no cia peb hais tias tag nrho cov kev hloov pauv no ua rau 1 MB ntawm cov ntaub ntawv, yog li sau ib qho thaiv - Block 1. Qhov thaiv no tau txais kev kos npe - hais. ASG 4.
Nov yog qhov peb thawj qhov thaiv zoo li.
Tam sim no cia peb tsim qhov thaiv thib ob.
Tom qab kev sib ntaus sib tua legendary nrog Frost giants, Thor yuav tsum tau kho nws lub zog rauj. Yog li, nws xa mus rau Asgard's Forge thiab them 0.1 BTC.
Loki xav ua kev lom zem ntawm Thor tus txiv tshiab, yog li nws xaj 100 cheeseburgers thiab noj coke los ntawm Asgard's version ntawm Wendy's. Qhov no raug nqi nws tag nrho ntawm 0.04 BTC.
Yog li, peb muaj cov kev hloov pauv hauv qab no:
T1: Thor – Asgard's Forge | 0.1 BTC
T2: Loki – Asgardian Wendy's | 0.04 BTC
Dhau li ntawm cov kev pauv no, Block 2 kuj suav nrog kos npe ntawm Block 1 - ASG 4. Tom qab ntawd Block 2 tau txais nws kos npe raws li cov ntaub ntawv nws muaj. Cia peb hais FUN27.
Raws li kev lag luam ntau tshwm sim ntawm blockchain, ntau cov blocks tau tsim, txhua qhov thaiv uas muaj qhov kos npe ntawm yav dhau los. Txoj kev no, Block 1 yog txuas ncaj qha rau Block 2. Block 2 ces txuas mus rau Block 3. Thaiv 4 mus rau Block 5, thiab lwm yam.
Tab sis yuav ua li cas yog tias ib tug neeg txiav txim siab hloov cov ntaub ntawv hauv Block 1?
Cia peb hais tias Loki, siab phem li nws, xav ua kom muaj teeb meem. Nws hloov tus nqi ntawm Bitcoin Thor tau txais los ntawm Odin los ntawm 0.2 rau 0.3. Txoj kev no, Thor yuav tau them nyiaj rau nws tsis tau txais.
Thiab ntawm no yog qhov uas tej yam yuav nyuaj. Tam sim no hais tias cov ntaub ntawv nyob rau hauv Block 1 txawv, kos npe, uas yog generated raws li cov ntaub ntawv nyob rau hauv lub block, hloov tau. Yog li ntawd es tsis txhob ASG 4, tus tshiab kos npe yuav, cia peb hais, ERR 2.
Muab hais tias qhov kos npe no suav nrog hauv Block 2, txoj hlua ntawm cov ntaub ntawv kuj hloov pauv, yog li hloov qhov kos npe ntawm Block 2 los ntawm FUN27 rau PAB 42.
Qhov no ua rau muaj kev cuam tshuam domino qhov twg txhua qhov kos npe ntawm txhua qhov thaiv hauv cov saw tau hloov pauv. Thaum cov neeg siv paub tias ib tug neeg tab tom sim hloov cov ntaub ntawv hauv cov blocks, lawv tsis lees txais cov kev hloov pauv thiab hloov lub blockchain rov qab mus rau lawv qhov kev siv tau dhau los.
Yog li cas kos npe tsim?
Yuav kom ncaj ncees, cov txheej txheem nws tus kheej yog qhov nyuaj heev. Feem ntau ntawm qhov no tseem suab zoo li cov khawv koob dub rau kuv, yog li kuv yuav nyob tawm ntawm cov khoom siv thev naus laus zis.
Tab sis hauv cov ntsiab lus yooj yim, cryptographic hash muaj nuj nqi (cov txheej txheem nyuaj) siv txoj hlua ntawm cov ntaub ntawv (cov kev lag luam hauv qhov thaiv) thiab hloov nws mus rau hauv 64 tus lej cim. Muaj ntau ntau yam hash ua haujlwm hauv online uas koj tuaj yeem ua si nrog - peb yuav siv qhov no yog ib rau peb qhov piv txwv.
Los ntawm kev ntxiv cov ntaub ntawv los ntawm peb thawj qhov thaiv hauv lub tshuab hluav taws xob hash, peb tau txais cov hlua hauv qab no:
786A832913348D9BB6E35ABF60CB451934F58A9E648CA2E28724A04AACEEBB6C
Yog hais tias ib tug cim nyob rau hauv cov ntaub ntawv input hloov, cov zis yuav txawv kiag li. Yog li yog tias Loki hloov qhov 0.2 BTC rau 0.3 BTC, peb cov zis yuav yog qhov no:
E69CC8EF3A3B3D569C6DCE67445B3699C3B01FDE588C27ED4AF34DCDAAC8D774
Qhov no yog vim li cas kev koom ua ke ntawm kev kos npe ntawm Block 1 (ASG4) rau hauv cov ntaub ntawv ntawm Block 2 ua rau nws tsis tuaj yeem hloov lub blockchain. Kev kos npe ntawm txhua qhov thaiv dhau los yog siv los tsim kos npe ntawm ib qho tom ntej.
Yog li ntawd mining tuaj qhov twg?
Contrary to popular kev ntseeg, crypto mining tsis yog hais txog kev tsim Bitcoin tshiab.
Miners sib tw nrog ib leeg kom lees paub qhov kev hloov pauv hauv txhua qhov thaiv, ua kom txhua qhov thaiv ntawm cov saw hlau haum rau qee yam.
Tab sis kom nkag siab tias txhua yam ua haujlwm li cas, peb yuav tsum xub tham txog cov nonces. Nonces yog qhov sib txawv ntxiv los ntawm blockchain rau txhua qhov thaiv. Lawv lub hom phiaj nkaus xwb yog hloov cov hash tso zis (kos npe) ntawm ib qho thaiv yam tsis tau hloov pauv cov ntaub ntawv ntawm kev hloov pauv. Cov nonces tau ntxiv vim tias txhua qhov kos npe ntawm txhua qhov thaiv yuav tsum pib nrog tus lej tshwj xeeb ntawm cov lej ua ntej.
Miners ces yuav tsum nrhiav tus nqi ntawm nonce kom validate cov muas thiab ntxiv cov tshiab thaiv rau lub blockchain. Yog tsis muaj formula los xam tus nqi ntawm nonce. Nws tsuas yog txheej txheem ntawm kev sim thiab ua yuam kev.
Thiab feem ntau, qhov ntau dua kev suav koj muaj, qhov nrawm dua koj tuaj yeem sim ntau yam nonces, thiab yog li nrhiav tus nqi zoo.
3. Decentralization ntawm blockchain
Tam sim no peb muaj ib daim duab meej ntawm qhov blockchain yog dab tsi thiab nws ua haujlwm li cas, cia peb tham txog ib qho ntawm nws qhov tseem ceeb - decentralization.
Decentralization yog ib qho ntawm blockchain cov ntsiab lus feem ntau ntsib. Ib tug decentralized blockchain txhais tau hais tias tsis muaj lub hauv paus ntsiab lus ntawm kev tswj rau tag nrho cov network. Hloov chaw, lub network tau khaws cia hauv ntau qhov chaw thoob plaws ntiaj teb.
Vitalik Buterin, tus co-founder ntawm Ethereum, cais decentralization rau hauv 3 ntau hom:
1. Architectural (de)centralization – Muaj pes tsawg lub cev khoom siv yog ib qho system ua los ntawm?
2. Kev nom kev tswv (de)centralization – Muaj pes tsawg tus neeg lossis cov koom haum tswj cov cuab yeej no?
3. Logical (de)centralization - Puas yog tag nrho lub network monolithic thiab koom nrog, lossis chaotic thiab disorganized?
Siv cov hom no, nws mam li faib ntau yam technologies thiab cov tsev kawm ntawv. Nws txhais lub blockchain raws li kev nom kev tswv decentralized, architecturally decentralized, thiab logically centralized.
Yuav ua li cas yog DLT?
Ntau tus ntseeg tias blockchain thiab faib cov ntaub ntawv thev naus laus zis yog ib qho thiab tib yam. Tab sis qhov ntawd tsis yog lawm.
Distributed Ledger Technology yog ib qho kev siv thev naus laus zis uas khaws nws cov ntaub ntawv hauv ntau qhov chaw, ntawm ntau lub cuab yeej, muaj thiab tswj los ntawm cov tib neeg lossis cov koom haum sib txawv.
Qhov sib txawv tseem ceeb ntawm ob yog DLT yog ib lub tshuab, thiab blockchain yog hom DLT.
Lub decentralization ntawm cov ntaub ntawv faib tawm lub hom phiaj los xaus qhov kev xav tau ntawm lub hauv paus tswj hwm uas ua haujlwm lossis siv tau cov kev lag luam hauv lub network. Qhov no txo qhov kev pheej hmoo ntawm qhov system kom muaj kev cuam tshuam hauv kev tawm tsam.
4. Yog li cas blockchain haum rau hauv cryptocurrency?
Blockchain lub luag haujlwm hauv kev lag luam crypto Nws yog yooj yim heev - nws sau thiab validates muas. Qhov no tso cai rau lub ntiaj teb crypto nyob twj ywm tsis qhia npe, nce nws txoj kev ruaj ntseg, thiab pab nws nyob twj ywm pob tshab thiab hloov tsis tau.
Tab sis qhov kev lag luam crypto zoo li cas?
Cia peb rov qab mus rau peb qhov piv txwv yav dhau los.
Rau Zeus xa cov 0.5 BTC rau Odin, nws thawj zaug xav tau lub hnab nyiaj uas tuaj yeem tuav Bitcoin.
- Zeus qhib nws lub hnab nyiaj thiab nkag rau Odin tus yuam sij pej xeem ua ke nrog cov nyiaj uas nws xav xa.
- Tom qab ntawd nws ntaus hauv nws tus yuam sij ntiag tug kom paub meej tias qhov kev hloov pauv.
- Hermes, uas yog ib tug miner, tsub nqi 0.00005 BTC kom suav nrog kev lag luam hauv blockchain. Xav txog qhov no raws li tus nqi thauj khoom, uas tau muab tso rau hauv tus nqi kawg.
- Tom qab ntawd qhov kev hloov pauv tau raug lees paub los ntawm cov nodes, teev sijhawm, thiab ntxiv rau lawv cov version ntawm blockchain.
- Odin thaum kawg tau txais 0.5 BTC.
Tam sim no, nyob ib ncig ntawm 300,000 BTC kev lag luam tau lees paub txhua hnub. Koj tuaj yeem saib tag nrho cov kev hloov pauv thaum lawv tshwm sim blockchain.com.
Crypto hnab nyiaj
Contrary to popular kev ntseeg, crypto hnab nyiaj tsis txhob khaws koj cov npib crypto tiag tiag. Hloov chaw, lawv pab koj ua kev lag luam, taug qab koj qhov nyiaj tshuav, thiab qhov tseem ceeb tshaj plaws, khaws koj cov lej pej xeem thiab ntiag tug.
Koj tus yuam sij pej xeem zoo li koj tus lej nyiaj hauv tuam txhab nyiaj. Koj qhia rau lwm tus kom lawv tuaj yeem tso nyiaj rau hauv koj tus account.
Koj tus yuam sij pej xeem yog tsim los ntawm koj tus lej ntiag tug.
Ntawm qhov tod tes, koj tus yuam sij ntiag tug zoo li tus lej ruaj ntseg. Koj tsuas yog tus uas yuav tsum paub. Txwv tsis pub, tib neeg yuav tuaj yeem lees paub kev lag luam sawv cev rau koj. Thiab tsis muaj nws, koj yuav tsis muaj peev xwm lees paub qhov kev hloov pauv lossis thim nyiaj.
5. Cov txiaj ntsig ntawm blockchain
Blockchain thev naus laus zis los nrog ntau cov txiaj ntsig, uas tuaj yeem muaj kev cuam tshuam loj rau txoj kev lag luam ua tau zoo nrog rau kev txaus siab ntawm lawv cov neeg siv khoom.
Cov ntaub ntawv tsis hloov tau
Tag nrho cov ntaub ntawv khaws tseg rau ntawm blockchain yog qhov ruaj khov. Tsis muaj leej twg hloov tau, thiab tsis muaj leej twg yuav tshem tau nws. Qhov no tso cai rau cov lag luam thiab cov tib neeg taug qab tag nrho lawv cov kev lag luam zoo thiab yooj yim.
Tab sis hloov cov ntaub ntawv ntawm blockchain yog tsis yooj yim sua. Nws tsuas yog heev, nyuaj heev.
Thiab thaum lub suab tsis hloov pauv tau zoo li lub tswv yim zoo (thiab feem ntau yog), nws kuj tuaj yeem ua rau ntau yam teeb meem rau kev lag luam. Yuav ua li cas yog tias, los ntawm kev huam yuaj, cov ntaub ntawv rhiab tau luam tawm ntawm blockchain?
Tib txoj kev los kho qhov no yog los ntawm kev ntxias lwm tus neeg koom nrog hauv blockchain kom muaj "khob" - faib cov blockchain rau hauv 2 txoj hauv kev thiab txav cov ntaub ntawv mus rau ib qho ntawm lawv. Tab sis ua qhov no ntawm pej xeem blockchain yog ib sab ua tsis tau.
Txawm li cas los xij cov teeb meem no feem ntau zam dhau los ntawm blockchain tus qauv tsim, uas cais cov ntaub ntawv rhiab thiab txheeb xyuas.
Digital ywj pheej
Feem ntau ntawm cov ntaub ntawv hauv internet yog tswj los ntawm 4 lub tuam txhab loj - Google, Microsoft, Amazon, thiab Facebook. Txhua daim duab lossis yeeb yaj kiab koj tau khaws cia hauv huab lossis tshaj tawm hauv online, txhua lub suab lus lossis email koj puas tau xa, koj tus cwj pwm kev yuav khoom, thiab koj qhov chaw keeb kwm yog tag nrho khaws cia rau hauv lawv cov servers.
Tag nrho cov ntaub ntawv ntawm blockchain, suav nrog cov ntsiab lus ntawm kev sib pauv, yog encrypted. Tus yuam sij pej xeem tsis tuaj yeem taug qab mus rau ib tus neeg siv lossis tuam txhab tshwj xeeb, yog li tiv thaiv kev taug qab ntawm kev yuav khoom.
Security
Nyob rau hauv lub ntiaj teb niaj hnub no, kev ruaj ntseg yog ib qho tseem ceeb tshaj plaws ntawm txhua lub tshuab.
Daim ntawv tshaj tawm qhia tau hais tias, qhov nruab nrab, kev tawm tsam hacker tau ua tiav txhua txhua 39 feeb. Cov npav rho nyiaj, tus kheej, thiab cov ntaub ntawv cais tau raug nyiag txhua hnub. Qhov no ua rau ntau lab daus las poob txhua xyoo.
Tab sis txij li thaum lub blockchain yog ib tug decentralized system, nws tsis muaj ib tug point ntawm tsis ua hauj lwm.
Cov ntaub ntawv khaws cia rau hauv ntau lub khoos phis tawj txuas nrog lub network, yog li kev tawm tsam yuav luag tsis yooj yim sua. Txhawm rau tswj hwm lub network lossis hloov cov ntaub ntawv khaws cia ntawm blockchain, koj yuav tsum tawm tsam txhua lub network cov khoom siv ib zaug.
Qhov no yuav xav tau kev ua haujlwm ntau thiab suav lub zog thiab yuav ua pov thawj tsis muaj txiaj ntsig, vim tias kev tawm tsam ntawm tag nrho lub network yuav ua rau tus nqi ntawm cryptocurrency poob qis.
Thaum kawg, kev nqis peev uas yuav tsum tau ua kom muaj kev tawm tsam zoo li no yuav loj dua nws cov txiaj ntsig thaum kawg.
Anonymity
Lub blockchain tso cai rau koj nyob twj ywm tsis qhia npe. Tsis muaj leej twg tuaj yeem taug qab koj qhov kev yuav khoom lossis koj tus cwj pwm kev siv nyiaj thiab txuas lawv rau koj cov ntaub ntawv ntiag tug kom lawv tuaj yeem tau nyiaj tom qab nws. Tshwj tsis yog lawv paub tseeb tias qhov chaw nyob pej xeem twg yog koj li.
Tab sis txawm li ntawd los, lub kaw lus ua tiav ntawm blockchain thev naus laus zis yuav tsis khaws cov ncuav qab zib lossis cov ntaub ntawv tus kheej. Thiab qhov no yog vim li cas Bitcoin tawg nyob rau hauv muaj koob meej ntawm kev lag luam dub thiab lub vev xaib tsaus.
Tab sis thaum lub blockchain tuaj yeem muab tsis qhia npe, nco ntsoov tias feem ntau cov vev xaib hauv internet siv cov ncuav qab zib. Yog li txawm tias koj xaiv them nrog Bitcoin ntawm lub vev xaib zoo li Amazon, lawv tseem tuaj yeem khaws koj cov ntaub ntawv.
Txo tus nqi
Qhov sib txawv tseem ceeb ntawm Bitcoin thiab cov tsev txhab nyiaj yog tias Bitcoin tus nqi yog tiaj tus. Cov tsev txhab nyiaj feem ntau them ib feem pua ntawm cov nyiaj pauv, xws li 1% mus rau 4%. Qhov no txhais tau tias ntawm kev hloov ntawm $ 10,000, lub txhab nyiaj tuaj yeem them qhov twg ntawm $ 100 thiab $ 400.
Ntawm qhov tod tes, Bitcoin kev lag luam them tus nqi tiaj tus, tab sis nws yog raws li tus nqi lag luam. Thaum lub sijhawm sau ntawv, tus nqi pauv yog $ 1.62. Tus nqi pauv siab tshaj plaws yog $62.79 thaum lub Plaub Hlis 21, 2021. Qhov ntawd tseem qis dua 1% ntawm $ 10,000 kev hloov pauv.
Tsis muaj kev tswj nyiaj txiag los ntawm tsoomfwv
Cov tsev txhab nyiaj thiab tsoomfwv tuaj yeem khov ib tus as khauj yam tsis muaj ntawv ceeb toom yog tias lawv xav tias tsim nyog. Ntau tus neeg muaj lawv cov nyiaj khov txhua hnub tsis nkag siab vim li cas.
Hauv lub network blockchain, tib tus neeg uas nkag mus rau koj cov nyiaj yog koj tus kheej. Zoo, thiab txhua tus neeg uas muaj koj tus lej ntiag tug (tsis muaj leej twg yuav tsum, txawm li cas los xij). Tsoom fwv, koj lub txhab nyiaj hauv lub tebchaws, lossis lwm lub koom haum tsis tuaj yeem nkag mus rau koj cov nyiaj lossis taug qab koj cov kev lag luam yam tsis paub koj tus kheej thiab cov yuam sij rau pej xeem.
Qhov no txhais tau tias koj tau tswj hwm koj cov nyiaj tag nrho, thiab tsis muaj ib lub koom haum twg tuaj yeem tshem tawm ntawm koj yam tsis tau koj tso cai.
kawg xav
Blockchain yog ib qho loj heev.
Cov thev naus laus zis uas ua rau nws pom qhov tawg hauv qhov muaj koob meej hauv 2017 vim yog cryptocurrencies, tab sis qhov ntawd maj mam hloov. Blockchains tau tsim tawm rau pej xeem thiab ntiag tug los ntawm ntau lub lag luam thiab cov tib neeg, nrhiav kev siv hauv ntau yam lag luam. Thiab qhov ntawd tshwm sim vim lawv lub peev xwm loj heev.
Blockchain thev naus laus zis muaj lub zog los hloov pauv txoj hauv kev peb lub neej ua haujlwm.
Nws tuaj yeem cuam tshuam tag nrho txoj hauv kev hauv tuam txhab nyiaj ua haujlwm, txhawb nqa e-tsoom fwv, thiab txhawb kev siv lub zog ntsuab.
* Cov ntaub ntawv nyob rau hauv tsab xov xwm no thiab cov kev sib txuas tau muab yog rau cov ntaub ntawv dav dav nkaus xwb thiab yuav tsum tsis txhob suav nrog cov lus qhia txog nyiaj txiag lossis kev nqis peev. Peb qhia koj kom ua koj tus kheej kev tshawb fawb lossis sab laj nrog tus kws tshaj lij ua ntej txiav txim siab txog nyiaj txiag. Thov lees paub tias peb tsis muaj lub luag haujlwm rau ib qho kev poob uas tshwm sim los ntawm cov ntaub ntawv muaj nyob hauv lub vev xaib no.
