Hauvstainless hlau thiab nickel alloy kev lag luam, cov ntaub ntawv xeem cov ntaub ntawv (MTR) yog ib daim ntawv tseem ceeb tshaj plaws nyob rau hauv ib qho kev lag luam. Nws lees paub cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, kho cua sov, thiab NDE cov txiaj ntsig ntawm txhua lub yeeb nkab, haum, flange, thiab phaj. Ib tug engineer xaiv Inconel 625 yeeb nkab rau 350C qaub roj zoo ntseeg tias MTR yog tiag - vim hais tias Inconel 625 yeeb nkab nrog forged MTR tsis yog Inconel 625 kiag li. Nws tuaj yeem yog cov hlau tsis zoo 316L stainless hlau, lossis qhov phem dua, melted - lub tsheb kauj vab ncej nrog lub laser -etched "UNS N06625" cim. Thiab thaum cov yeeb nkab ntawd tsis nyob hauv ib puag ncig hydrogen sulfide ntawm 10,000 psi, nws tsis xau - nws tawg. Kev puas tsuaj.
Kev lag luam hlau thoob ntiaj teb poob kwv yees li $2-5 nphom txhua xyoo rau cov khoom cuav thiab cov khoom tsis zoo. Blockchain thev naus laus zis muab thawj qhov kev daws teeb meem rau qhov teeb meem no los ntawm kev tsim ib qho kev hloov tsis tau, cryptographically ruaj ntseg digital saw uas txuas txhua yam khoom tsis muaj steel hlau rau nws daim ntawv pov thawj zeb qub, txhua qhov kev tswj xyuas kev hloov pauv, thiab txhua txoj kev hloov pauv - los ntawm hluav taws xob arc rau qhov kawg welded sib koom ntawm qhov chaw. Tsis muaj ib tog twg tuaj yeem hloov cov ntaub ntawv yam tsis muaj kev tshawb pom. Tsis muaj cov khoom cuav tuaj yeem muab tso rau hauv cov saw hlau. Thawj thawj zaug hauv keeb kwm ntawm kev lag luam steel, daim ntawv MTR tuaj yeem thim rov qab los ntawm kev ua lej pov thawj ntawm qhov tseeb.
Cov lus qhia no suav nrog: yuav ua li cas cov hlau tsis muaj hlau cuav nkag mus rau hauv cov khoom siv; blockchain technology ua haujlwm li cas (hash chains, faib ledgers, ntse daim ntawv cog lus); yuav ua li cas siv traceability ntawm zeb kub tooj mus rau qhov kawg installation; kev sib raug zoo ntawm blockchain, EN 10204 MTRs, thiab ASTM cov qauv; tiag tiag-cov kauj ruam ua haujlwm hauv ntiaj teb rau cov khoom lag luam stainless hlau lossis cov chaw tsim khoom; thiab cov ntaub ntawv nyiaj txiag: kev txuag nqi los ntawm kev tiv thaiv kev dag ntxias, txo kev tshuaj xyuas, thiab kev daws teeb meem sai dua.
Yuav ua li cas Counterfeit Stainless hlau nkag mus rau hauv Supply Chain
Cov hlau tsis muaj hlau cuav nkag mus rau hauv cov saw hlau feem ntau los ntawm cov ntaub ntawv xeem cov ntaub ntawv (MTRs). PDF MTR tuaj yeem hloov pauv hauv Microsoft Word hauv qis dua tsib feeb - hloov "316L" mus rau "Inconel 625," hloov cov ntsiab lus nickel los ntawm 12% mus rau 61%, thiab dhau los ua tus soj ntsuam kos npe kos npe los ntawm lwm daim ntawv. Tsis muaj cryptographic mechanism nyob rau hauv daim ntawv tam sim no / PDF-raws li MTR system los ua pov thawj tias cov ntaub ntawv tsis tau raug cuam tshuam nrog. Kev tiv thaiv nkaus xwb yog kev ntseeg siab - thiab kev ntseeg tsis yog kev tswj hwm engineering.
Qhov teeb meem tsis zoo ntawm cov hlau tsis zoo yog tsis theoretical. Hauv xyoo 2018, ib lub tuam txhab loj nyob sab Europe nuclear tau tshawb pom tias Inconel 690 chav tshuab hluav taws xob cov raj xa nrog forged MTRs muaj tsawg dua 30% nickel - tsawg dua li ib nrab ntawm 58% yam tsawg kawg nkaus. Cov hlab tau raug teeb tsa thiab lub reactor tau ua haujlwm rau ntau tshaj li ib xyoos ua ntej qhov kev dag ntxias raug kuaj pom thaum lub sij hawm niaj hnub tshuaj xyuas ultrasonic uas qhia txog kev npaj txhij txog phab ntsa thinning. Tus nqi ncaj qha ntawm kev hloov pauv tau tshaj 120 lab, tsis suav nrog cov nqi hluav taws xob poob thaum lub sijhawm kaw 18 lub hlis. Lub hauv paus ua rau? MTR forged uas tsis muaj leej twg muaj cov cuab yeej los xyuas.
Xyoo 2021, American Petroleum Institute (API) tau tshaj tawm tsab xov xwm ceeb toom tias cov yeeb yaj kiab API 5L kab yeeb nkab nrog forged MTRs tau tshawb pom nyob rau hauv tsawg kawg rau lub teb chaws, nrog rau qee cov khoom siv qhia tau tias muaj zog 40% hauv qab no specification. Cov yeeb nkab tau nkag mus rau hauv cov saw hlau los ntawm ntau lub tuam txhab plhaub uas tau yuav cov khoom lag luam tsis lees paub, rov- cim nws nrog laser- kos cov cim sib piv MTRs dag, thiab muag nws los ntawm cov neeg muag khoom raug cai uas tso siab rau daim ntawv pov thawj. Tsis muaj leej twg txheeb xyuas cov ntawv pov thawj vim tias tsis muaj txoj hauv kev ua tau zoo yam tsis tau xa cov qauv rau kev kuaj kev ywj pheej ntawm kev sim - tus txheej txheem uas siv sijhawm 4-6 lub lis piam thiab raug nqi $ 2,000-5,000 ib lub tshav kub.
Xya qhov tsis muaj zog txuas hnub no yog daim ntawv -raws li kev taug qab
Tam sim no stainless hlau traceability system muaj xya yam ntxwv tsis muaj zog uas blockchain ncaj qha chaw nyob. Txhua qhov tsis muaj zog yog qhov tsis zoo uas cov neeg dag ntxias siv. Blockchain tshem tawm rau ntawm xya los ntawm kev tsim - tsis yog los ntawm txoj cai, tab sis los ntawm cryptography.

A Steel Industry Explanation
Txhawm rau nkag siab tias blockchain ua haujlwm li cas rau stainless hlau traceability, xav txog qhov piv txwv yooj yim. Lub tshuab zeb steel tsim cov cua sov ntawm Inconel 625, xaiv Kub #INC625-2026-0811-A.
Kauj ruam 1:Thaiv 1 (Mill Creation):
Cov ntaub ntawv sau tseg: kub tooj, tshuaj muaj pes tsawg leeg (Ni: 61.2%, Cr: 21.8%, Mo: 8.9%, Nb: 3.5%), txhua yam khoom (UTS: 855 MPa, YS: 448 MPa, Elongation: 32%), kev kho cua sov (1,150C, dej quenched dhau), NDE cov txiaj ntsig
Cov ntaub ntawv no tau hloov pauv mus rau qhov tshwj xeeb digital ntiv tes siv SHA-256 - piv txwv li, "a3f8c2d1e4b5..." (64 tus lej hexadecimal)
Thaiv 1 yog tsim nrog cov ntaub ntawv no + hash + ib lub sij hawm + kos npe digital ntawm tus tswj xyuas zoo
Kauj ruam 2:Thaiv 2 (Shipment rau Distributor):
Cov ntaub ntawv kaw: cov yeeb nkab qhov ntev (12 "SCH 40 x 6m), kom muaj nuj nqis (50 daim), daim nqi ntawm tus lej, hnub xa khoom, npe neeg txais
Block 2 muaj: cov ntaub ntawv hloov tshiab tshiab + cov hash ntawm Block 1 + tshiab hash ntawm Block 2
Thaiv 2 yog digitally kos npe los ntawm ob lub zeb (tus neeg xa khoom) thiab tus xa khoom (tus neeg txais)
Kauj ruam 3:Thaiv 3 (Txiav thiab Fabrication):
Cov ntaub ntawv kaw tseg: 2 daim txiav los ntawm niam txiv yeeb nkab #INC625-2026-0811-A-001 (me nyuam ID: #INC625-2026-0811-A-001-01 thiab 001-02), txoj kev txiav (band saw), tshuaj xyuas tom qab txiav (VT tau)
Thaiv 3 muaj: cov ntaub ntawv fabrication + cov hash ntawm Block 2 + ib tug tshiab hash ntawm Block 3
Thaiv 3 yog digitally kos npe los ntawm tus fabricator
Tam sim no, xav tias tus neeg dag ntxias sim hloov cov tshuaj muaj pes tsawg leeg hauv Block 1 los ntawm "Ni: 61.2%" rau "Ni: 12.1%" (kom dhau 316L li Inconel 625). Hloov txawm ib tus cwj pwm hloov qhov hash ntawm Block 1 los ntawm "a3f8c2d1e4b5..." rau ib yam dab tsi txawv kiag li - hais tias, "7d2e9f1a3c4b ...". Tam sim no Block 2 muaj cov qub hash ntawm Block 1 ("a3f8c2d1e4b5 ..."), tab sis qhov tseeb Block 1 tam sim no muaj hash "7d2e9f1a3c4b ...". Qhov tsis sib haum xeeb yog pom tau tam sim los ntawm txhua tus neeg koom nrog network uas sib piv cov hashes khaws cia. Txhawm rau nkaum qhov kev dag ntxias, tus neeg cuav yuav tsum rov xam cov hashs ntawm Blocks 2, 3, thiab txhua qhov txuas txuas ntxiv hauv cov saw - thiab ua li ntawd rau hauv ib lub network uas muaj ntau tus neeg sab nraud tuav cov ntawv luam ntawm daim ntawv teev npe. Qhov no yog xam infeasible nrog technology tam sim no.
Public vs Private vs Consortium Blockchain - Tus qauv twg rau Steel?
Rau cov saw hlau stainless hlau, ib lub koom haum ntiag tug blockchain ua haujlwm los ntawm ib pawg neeg koom nrog (mills, distributors, fabricators, end-cov neeg siv, thiab cov chaw soj ntsuam ywj pheej) yog cov qauv zoo. Nws muab immutability thiab pob tshab rau txhua tus neeg koom nrog kev tso cai thaum tiv thaiv tus nqi lag luam thiab cov ntaub ntawv cog lus. Public blockchains (xws li Ethereum) yog qhov tsis tsim nyog vim yog cov nqi lag luam siab, lub sijhawm lees paub qeeb, thiab kev pom ntawm pej xeem ntawm txhua cov ntaub ntawv hloov pauv.

Nws txhawb kev ntiag tug, kev pom zoo, thiab cov ntawv cog lus ntse (hu ua "chaincode" hauv Fabric terminology). Tau qhov twg los: Hyperledger Foundation (www.hyperledger.org).
Daim ntawv cog lus ntse - Automating the Traceability Rules
Cov ntawv cog lus ntse yog tus kheej - ua haujlwm cov kev pabcuam khaws cia ntawm blockchain uas cia li tswj hwm txoj cai taug qab ntawm cov khoom siv. Piv txwv li, daim ntawv cog lus ntse tuaj yeem raug tsim los tsis lees txais cov khoom xa tuaj uas tus neeg tau txais tsis tau digitally lees paub tias tau txais hauv 48 teev, lossis txhawm rau chij ib pawg uas PMI cov txiaj ntsig tsis sib xws rau zeb - ntawv pov thawj chemistry nyob rau hauv ib qho kev kam rau siab. Cov ntawv cog lus ntse tshem tawm qhov xav tau ntawm kev ua raws li phau ntawv txheeb xyuas - blockchain tswj hwm cov cai hauv kev ua haujlwm.
Nyob rau hauv ib tug stainless hlau traceability system, ntse daim ntawv cog lus yuav automate:
- MTR Validation: Thaum tus neeg xa khoom tau txais cov khoom xa tuaj, daim ntawv cog lus ntse cia li sib piv PMI (XRF) nyeem ntawv tawm tsam lub zeb- ntawv pov thawj chemistry khaws cia ntawm blockchain. Yog tias Ni cov ntsiab lus nyob sab nraud 5% ntawm tus nqi tau lees paub, cov khoom xa tuaj yog chij rau kev tsis lees paub ua ntej raug lees txais rau hauv cov khoom muag.
- Custody Transfer: Kev xa khoom xa tuaj tsis raug kaw raws li "xa" kom txog thaum ob tus neeg xa khoom thiab tus neeg tau txais digital kos npe rau kev sib pauv. Daim ntawv cog lus ntse tswj lub sijhawm lub sijhawm (piv txwv li, 48 teev) rau tus neeg txais kev pom zoo lossis tsis txaus siab daim ntawv txais - tom qab uas cov xwm txheej tau txiav txim siab "tau txais" lossis "tsis pom zoo."
- Daim ntawv pov thawj tas sij hawm: Yog tias ib lub batch tau nyob rau hauv cov khoom muag ntev dua li lub neej txee (piv txwv li, 24 lub hlis rau MTR siv tau raws li EN 10204), daim ntawv cog lus ntse tau chij cov batch rau re- ntawv pov thawj ua ntej nws tuaj yeem xa mus rau tus neeg siv khoom tshiab.
- Chain of Custody: Thaum cov yeeb nkab raug txiav rau hauv ob daim thaum lub sij hawm tsim, daim ntawv cog lus ntse cia li tsim cov me nyuam blockchain IDs txuas rau niam txiv ID, xyuas kom meej tias txhua daim ntawv txiav tau txais cov ntaub ntawv pov thawj ntawm niam txiv cov ntaub ntawv.

EU Digital Product Passport (DPP) - Tus Txheej Txheem Cai
Lub EU Digital Product Passport (DPP), raug txib raws li Ecodesign for Sustainable Products Regulation (ESPR), yuav xav kom tag nrho cov khoom muag hauv EU - suav nrog cov khoom steel - kom nqa cov ntaub ntawv digital ntawm lawv cov khoom muaj pes tsawg leeg, keeb kwm, thiab ib puag ncig hneev taw. Blockchain yog lub ntiaj teb thev naus laus zis platform rau DPP vim tias nws muab kev hloov pauv tsis tau thiab ntau - tog nkag mus rau cov khoom lag luam uas yuav tsum tau khaws cia thiab hloov kho los ntawm ntau tus neeg ua yeeb yam thoob plaws lub neej ntawm cov khoom lag luam. Stainless hlau distributors uas siv blockchain traceability niaj hnub no yog tsim cov infrastructure uas yuav tsum tau rau EU kev lag luam nkag los ntawm 2027-2028.
EU DPP txoj cai, tau txais kev pom zoo hauv 2024 thiab nkag mus rau theem kev tswj hwm ntawm 2026 thiab 2030, xav kom txhua yam khoom tso rau hauv EU ua lag luam nqa cov khoom lag luam digital passport - nkag tau los ntawm QR code lossis cov ntaub ntawv zoo sib xws - uas muaj: cov ntaub ntawv muaj pes tsawg leeg (% ntawm txhua lub ntsiab lus, suav nrog cov khoom siv rov ua dua tshiab), lub teb chaws ntawm cov khoom siv hluav taws xob, cov khoom siv hluav taws xob ib puag ncig, cov khoom siv hluav taws xob ib puag ncig (cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob) dej siv, pov tseg tsim), thiab cov ntaub ntawv kho kom zoo / rov ua dua tshiab.
Rau cov khoom siv stainless hlau, qhov no txhais tau hais tias txhua cov yeeb nkab, haum, thiab flange yuav xav tau cov ntaub ntawv digital uas taug qab rov qab mus rau lub hauv paus chiv keeb steel zeb thiab sau cov ntaub ntawv ib puag ncig ntawm nws cov khoom. Blockchain-raws li traceability systems, uas twb tau sau cov xov tooj cua sov, tshuaj lom neeg muaj pes tsawg leeg, thiab kev saib xyuas kev hloov pauv, tau muab tso rau los ua lub hauv paus thev naus laus zis rau kev ua raws li DPP hauv kev lag luam steel. Lwm txoj hauv kev - tswj cov khoom lag luam digital passport databases - yog ob qho tib si rov ua dua thiab tsis muaj kev nyab xeeb dua li kev daws teeb meem blockchain uas sib koom ua ke traceability thiab DPP rau hauv ib qho system.
[Source] Regulation (EU) 2024/1781 - Ecodesign for Sustainable Products Regulation (ESPR). Nkag mus rau hauv kev quab yuam thaum Lub Xya Hli 2024. DPP cov cai yuav tsum tau ua ntu zus los ntawm cov khoom lag luam los ntawm 2026. Cov khoom siv hlau yuav tsum suav nrog hauv 2027-2028 txoj haujlwm ua haujlwm.
ROI ntawm Blockchain Traceability

Cov lus nug nquag
Q: Puas yog blockchain hloov qhov xav tau rau EN 10204 Hom 3.1 daim ntawv pov thawj?
A: Tsis yog. Blockchain yog cov ntaub ntawv pov thawj digital uas txheeb xyuas daim ntawv pov thawj EN 10204 tsis tau hloov pauv txij li nws tau muab los ntawm lub zeb. Daim ntawv lossis daim ntawv pov thawj PDF tseem yog cov ntaub ntawv raug cai; lub blockchain muab cryptographic pov thawj ntawm nws qhov tseeb. Xav tias nws yog ib qho tamper- pov thawj foob ntawm lub raj mis tshuaj: cov tshuaj (MTR) yog qhov koj xav tau; lub foob (lub blockchain hash) qhia koj tsis muaj leej twg tau cuam tshuam nrog nws. Txoj cai lij choj thiab daim ntawv cog lus ntawm EN 10204 Hom 3.1/3.2 daim ntawv pov thawj tsis hloov pauv los ntawm blockchain - qhov txawv yog tias tam sim no koj tuaj yeem ua pov thawj daim ntawv pov thawj yog qhov tseeb hauv vib nas this, tsis yog lub lis piam.
Q: Ntau npaum li cas blockchain traceability nqi ib lub yeeb nkab?
A: Rau ib tug raug 12-inch SCH 40 Inconel 625 yeeb nkab muag rau $4,100, tus nqi ntxiv ntawm blockchain traceability yog kwv yees li $8-15 rau ib lub yeeb nkab - tsawg dua 0.4% ntawm tus nqi khoom. Qhov no suav nrog QR code laser npav ($ 2-3), cov ntaub ntawv sau rau hauv blockchain ($ 0.50-1.00 ib qho kev sib pauv), cov nqi khiav lag luam platform ($ 3-5 rau ib lub yeeb nkab amortized), thiab kev nkag mus rau qhov chaw pov thawj ($ 2-5 ib lub yeeb nkab). Rau cov khoom lag luam qis (piv txwv li, 316L stainless hlau ntawm $ 720 rau ib lub yeeb nkab), tus nqi yog kwv yees li $ 5-10 rau ib lub yeeb nkab (0.7-1.4% ntawm cov khoom muaj nqis). Tus nqi yuav tsum txo qis los ntawm 30-50% raws li blockchain platform technology loj hlob thiab kev lag luam ntim nce.
Q: Yuav ua li cas yog tias QR code puas lossis tsis tuaj yeem nyeem ntawm qhov chaw?
A: Yog tias QR code ntawm lub cev cov yeeb nkab puas lawm, cov khoom tseem tuaj yeem txheeb xyuas tau los ntawm nws cov xov tooj cua sov (uas yog stamped lossis laser -etched ntawm txhua cov yeeb nkab rau ASTM A999). Cov xov tooj cua sov tuaj yeem nkag tau manually rau hauv daim ntawv pov thawj, uas khaws tag nrho cov ntaub ntawv blockchain rau qhov cua sov ntawd. Qhov no yog vim li cas blockchain traceability tsis cia siab rau QR codes nkaus xwb - tus lej kub yog qhov tseem ceeb, thiab QR code yog qhov yooj yim rau kev luam theej duab sai dua. Nyob rau hauv ib puag ncig uas QR chaws yuav raug puas tsuaj (xws li, abrasive blasting, hnyav txheej), lub tshav kub tooj cim (feem ntau 5-8 hli siab cim, stamped los yog qis- kev ntxhov siab dot-peen cim) tseem nyeem tau txawm tias tom qab pleev xim thiab ntau xyoo ntawm kev pabcuam.
Q: Puas yog blockchain traceability ruaj ntseg tiv thaiv kev nyiag?
A: Blockchain tsis tiv thaiv txhua qhov kev hem thawj rau kev nyab xeeb, tab sis nws yog qhov sib txawv ntawm cov ntaub ntawv ib txwm muaj nyob rau hauv ib txoj kev tseem ceeb: tsis muaj ib qho kev ua tsis tiav. Ib txwm MTR database khaws cia rau ntawm ib lub server tuaj yeem raug nyiag los ntawm kev ua txhaum cai ntawm ib tus neeg rau zaub mov. Ib daim ntawv teev npe blockchain raug faib thoob plaws ntau qhov kev ywj pheej (mills, distributor, lub chaw soj ntsuam, kawg -tus neeg siv) - tus neeg tawm tsam yuav tsum tau ua tib zoo cuam tshuam 51% lossis ntau dua ntawm lub network nodes los hloov daim ntawv teev npe, uas yog qhov ua tsis tau zoo rau lub koom haum kev ruaj ntseg blockchain. Txawm li cas los xij, blockchain tsis tiv thaiv kev dag ntxias ntawm qhov taw tes ntawm cov ntaub ntawv nkag - yog tias ib tus neeg ua haujlwm tsis ncaj ncees nkag mus rau cov ntaub ntawv tsis tseeb ntawm cov spectrometer, blockchain yuav ncaj ncees sau cov ntaub ntawv cuav. Blockchain ua pov thawj tias cov ntaub ntawv tsis tau hloov pauv tom qab nkag; nws tsis ua pov thawj tias thawj cov ntaub ntawv nkag yog qhov tseeb. Qhov no yog vim li cas blockchain traceability yog qhov ua tau zoo tshaj plaws thaum ua ke nrog kev ywj pheej thib peb -kev tshuaj ntsuam xyuas tog neeg (EN 10204 Hom 3.2), qhov uas tus neeg soj ntsuam xyuas tias cov ntaub ntawv nkag ntawm txhua kauj ruam cuam tshuam rau cov khoom siv lub cev.
Q: Kuv puas yuav tsum kawm blockchain programming siv qhov system?
A: Tsis yog. Lub blockchain ua haujlwm hauv keeb kwm yav dhau, pom tsis tau rau hnub - rau - cov neeg siv hnub. Tus neeg soj ntsuam txais tau luam theej QR code nrog lub smartphone app - lawv pom lub cim ntsuab (tseem ceeb) lossis X liab (tsis lees txais). Ib tus neeg muag khoom muab daim ntawv pov thawj blockchain rau cov neeg siv khoom siv nrog ib qho nyem hauv ERP system. Tus thawj tswj hwm zoo saib cov ntawv pov thawj tiav rau txhua tus lej hluav taws xob los ntawm lub vev xaib dashboard uas zoo li cov khoom siv sib txuas sib txuas. Lub tshuab blockchain yog piv rau HTTPS raws tu qauv tom qab lub vev xaib: koj siv nws txhua hnub yam tsis tas yuav nkag siab TLS tuav tes lossis daim ntawv pov thawj chains. Qhov nyuaj yog tswj hwm los ntawm blockchain platform tus neeg zov me nyuam thiab cov kev sib koom ua ke uas tsim cov API txuas thiab cov neeg siv cuam tshuam.
Q: Yuav ua li cas blockchain tuav cov khoom uas txiav, welded, los yog hloov?
A: Qhov no yog ib qho tseem ceeb tshaj plaws ntawm blockchain traceability. Thaum niam txiv cov yeeb nkab (Blockchain ID #ABC-001) raug txiav ua ob daim, daim ntawv cog lus ntse yuav tsim ob tus menyuam ID (#ABC-001-01 thiab #ABC-001-02), txhua tus tau txais cov ntaub ntawv pov thawj tag nrho ntawm niam txiv. Thaum tus fabricator welds tus me nyuam daim #ABC-001-01 mus rau lwm cov yeeb nkab #DEF-002, ib tug tshiab blockchain pauv yog tsim rau lub welded los ua ke, txuas ob niam txiv daim thiab sau cov txheej txheem weld (WPS ID), welder ID, muab tub lim hlau batch, thiab weld NDE tau. Tus neeg siv kawg ntawm qhov chaw teeb tsa scans qhov kawg sib dhos spool thiab tuaj yeem laum los ntawm blockchain kom pom tag nrho cov keeb kwm ntawm txhua daim hlau hauv lub rooj sib txoos - los ntawm lub tshuab hluav taws xob mus rau qhov kawg vuam. Qib no ntawm traceability tam sim no xav tau lub lis piam ntawm cov ntaub ntawv tshawb fawb los ntawm cov ntaub ntawv archives; nrog blockchain, nws yuav siv sij hawm vib nas this.
