Ua fefe ou mata ma ua ma'i ou lima!
I tala talu ai, na matou feagai ai ma tekinolosi o loʻo fausia ai poloka poloka () ma mataupu e mafai ona faʻatinoina ma la latou fesoasoani (). Ua oo i le taimi e galue ai ma ou lima! Ina ia faʻatinoina pailate ma PoC (Faʻamaoniga o le Manatu), ou te manaʻo e faʻaoga ao, aua ... e mafai ona maua mai soʻo se mea i le lalolagi ma, masani, e leai se manaʻoga e faʻaumatia le taimi i le faʻapipiʻiina o le siosiomaga, aua O lo'o iai fa'atonuga. O lea la, ia tatou faia se mea faigofie, mo se faʻataʻitaʻiga, o se fesoʻotaʻiga mo le fesiitaiga o tupe i le va o tagata auai ma taʻu tauagafau Bitcoin. Mo lenei mea o le a matou faʻaogaina le IBM cloud ma le lautele blockchain Hyperledger Fabric. Muamua, seʻi o tatou vaʻai pe aisea ua taʻua ai le Hyperledger Fabric o se poloka poloka lautele?
Hyperledger Fabric - o se poloka poloka lautele
I se tulaga lautele, o se faiga faʻamatalaga lautele e:
- Se seti o 'auʻaunaga ma se polokalama faakomepiuta e faʻatino faʻamatalaga pisinisi;
- Interfaces mo fegalegaleaiga ma le faiga;
- Meafaigaluega mo le resitalaina, faʻamaonia ma le faʻatagaina o masini / tagata;
- Fa'amaumauga e teu ai fa'amaumauga fa'agaioiga ma fa'amaumauga:
O le fa'amatalaga aloaia o le Hyperledger Fabric e mafai ona faitau i , ma i se faapuupuuga, o le Hyperledger Fabric o se faʻasalalauga tatala lea e mafai ai ona e fausia ni poloka poloka tumaoti ma faʻataunuʻuina konekarate atamai faʻapitoa e tusia i le JS ma le Go programming language. Sei o tatou vaʻavaʻai auiliili ile fausaga ole Hyperledger Fabric ma ia mautinoa o se faiga faʻapitoa lea e naʻo faʻamatalaga patino mo le teuina ma le pueina o faʻamaumauga. O le tulaga faʻapitoa o faʻamaumauga, e pei o poloka poloka uma, o loʻo teuina i totonu o poloka e tuʻu i luga o le poloka poloka pe a na o le au auai e ausia se maliega ma a maeʻa ona puʻeina faʻamaumauga e le mafai ona faʻasaʻo lemu pe tape.
Hyperledger Fabric Architecture
O le ata o loʻo faʻaalia ai le fausaga o le Hyperledger Fabric:
Faalapotopotoga - faʻalapotopotoga o loʻo i ai tupulaga, i.e. poloka poloka o loʻo i ai ona o le lagolago a faʻalapotopotoga. O faʻalapotopotoga eseese e mafai ona avea ma vaega o le ala tutusa.
alāvai - o se fausaga talafeagai e tuufaatasia ai tupulaga i vaega, i.e. o le poloka poloka ua faʻamaonia. E mafai e le Hyperledger Fabric ona fa'agasolo i le taimi e tasi le tele o poloka poloka fa'atasi ai ma manatu fa'apisinisi eseese.
Tu'uina atu Au'aunaga Fa'aui (MSP) ose CA (Pulega Fa'amaonia) mo le tu'uina atu o fa'asinomaga ma le tofiaina o matafaioi. Ina ia faia se node, e tatau ona e fegalegaleai ma le MSP.
Nodes a tupulaga - faʻamaonia fefaʻatauaiga, teuina le poloka poloka, faʻatino konekarate atamai ma fegalegaleai ma talosaga. E iai le fa'asinomaga a tupulaga (pepa numera), lea e tu'uina atu e le MSP. E le pei o le Bitcoin poʻo le Etherium network, lea e tutusa uma ai aia tatau, i Hyperledger Fabric nodes e eseese matafaioi:
- Masalo o tupulaga lagolago a tupulaga (EP) ma faatino konekarate atamai.
- Tautino a tupulaga (CP) - naʻo le faʻasaoina o faʻamatalaga i totonu o poloka poloka ma faʻafouina le "lalolagi o le lalolagi".
- Taula Peer (AP) - afai e tele faʻalapotopotoga o loʻo auai i le poloka poloka, ona faʻaogaina lea o tupulaga taula mo fesoʻotaʻiga i le va oi latou. E tatau i fa'alapotopotoga uma ona iai se tasi pe sili atu fo'i fa'agatama taula. I le fa'aaogaina o le AP, so'o se tupulaga i totonu o se fa'alapotopotoga e mafai ona maua fa'amatalaga e uiga i tupulaga uma i isi fa'alapotopotoga. Fa'aoga e fa'amaopoopo fa'amatalaga i le va o AP .
- Ta'ita'i Peer - afai o se faʻalapotopotoga e tele a latou paaga, ona naʻo le taʻitaʻi o le tupulaga o le a mauaina poloka mai le Ordering service ma tuʻuina atu i isi vaega. O le ta'ita'i e mafai ona fa'ailoa fa'amautu pe filifilia fa'amalosi e tupulaga i le fa'alapotopotoga. O lo'o fa'aoga fo'i le fa'atalatala e fa'amaopoopo fa'amatalaga e uiga i ta'ita'i.
aseta - fa'alapotopotoga e iai le taua ma o lo'o teuina ile poloka poloka. Aemaise lava, o faʻamaumauga autu-taua lea i le JSON format. O faʻamaumauga nei o loʻo faʻamauina i le Blockchain. E i ai a latou talaʻaga, o loʻo teuina i totonu o poloka poloka, ma se tulaga o loʻo i ai nei, o loʻo teuina i totonu o le "World state" database. O faʻamaumauga faʻamaumauga e faʻatumu faʻapitoa e faʻatatau i galuega faʻapisinisi. E leai ni fanua mana'omia, na'o le pau lava le fautuaga o aseta e tatau ona i ai se tagata e ona ma taua.
Ledger - e aofia ai le Blockchain ma le Word state database, lea e teu ai le tulaga o loʻo iai nei. Fa'aaoga e le setete o le lalolagi le LevelDB po'o le CouchDB.
Konekalate atamai - faʻaaogaina konekarate atamai, o loʻo faʻatinoina le faʻatautaia pisinisi o le faiga. I le Hyperledger Fabric, o konekarate atamai e taʻua o le code code. O le fa'aogaina o le chaincode, o aseta ma fefa'ataua'iga i luga oi latou o lo'o fa'amaonia. I faaupuga faʻapitoa, o konekarate atamai o polokalame faʻapipiʻi faʻatinoina i le JS poʻo le Go polokalame gagana.
Faiga fa'amaonia - mo filifili filifili taitasi, e mafai ona e setiina se faiga faavae i luga o le tele o faʻamaoniga mo se fefaʻatauaiga e tatau ona faʻamoemoeina ma mai ai. Afai e le o setiina le faiga faavae, o le faaletonu o le: "o le fefaʻatauaiga e tatau ona faʻamaonia e soʻo se sui o soʻo se faʻalapotopotoga i totonu o le auala." Fa'ata'ita'iga o faiga fa'avae:
- O le fefaʻatauaiga e tatau ona faʻamaonia e soʻo se pule o le faʻalapotopotoga;
- E tatau ona faʻamaonia e soʻo se sui poʻo se tagata o tausia o le faʻalapotopotoga;
- E tatau ona fa'amaonia e so'o se fa'alapotopotoga a tupulaga.
Auaunaga oka - fa'apipi'i fefa'ataua'iga i poloka ma tu'u atu i tupulaga i le alalaupapa. Fa'amaonia le tu'uina atu o fe'au i tupulaga uma i luga ole feso'otaiga. Fa'aaogaina mo faiga fa'apisinisi , mo le atinaʻe ma suʻega .
CallFlow
- O le talosaga e fesoʻotaʻi ma Hyperledger Fabric e faʻaaoga ai Go, Node.js poʻo Java SDK;
- E faia e le kalani se fefa'ataua'iga tx ma tu'uina atu i le fa'amaonia o tupulaga;
- E fa'amaonia e le Peer le saini a le kalani, fa'auma le fefa'atauaiga, ma toe lafo atu le saini fa'amaonia i le kalani. O le Chaincode e fa'atinoina na'o le paaga fa'amaonia, ma o le fa'ai'uga o lona fa'ataunu'uina e lafo atu i tupulaga uma. O lenei algorithm o galuega e taʻua o le PBFT (Practical Byzantine Fault Tolerant) consensus. E ese mai o le mea moni o le feʻau e auina atu ma faʻamaoniga e le o faʻamoemoeina mai tagata auai uma, ae naʻo se seti faapitoa;
- A mae'a ona maua e le kalani le numera o tali e fetaui ma le tulafono fa'amaonia, na te tu'uina atu le fefa'ataua'iga i le tautua oka;
- O le auaunaga o le Ordering e fa'atupuina ai se poloka ma tu'uina atu i tagata uma o lo'o galulue fa'atasi. O le fa'atonuina o auaunaga e fa'amautinoa ai le fa'amauina fa'asologa o poloka, lea e fa'aumatia ai le mea e ta'ua o le tui tusi ();
- E maua e le tupulaga se poloka, toe siaki le tulafono faʻamaonia, tusi le poloka i le poloka poloka ma suia le setete i le "World state" DB.
O na. O le mea lea e maua ai le vaevaega o matafaioi i le va o nodes. Ole mea lea e faʻamautinoa ai ole poloka poloka e mafai ona faʻaogaina ma malupuipuia:
- O konekarate atamai (chaincode) e fa'atino le fa'amaoniaina o tupulaga. E fa'amautinoaina le le faalauaiteleina o konekarate atamai, aua e le o teuina e tagata auai uma, ae na o le lagolagoina o uo.
- E tatau ona vave galue le oka. E fa'amautinoaina i le mea moni e na'o le fa'atonuina o se poloka ma tu'uina atu i se seti mautu o tupulaga ta'ita'i.
- O le tuʻuina atu o tupulaga e naʻo le teuina o poloka poloka - e mafai ona tele ma latou te le manaʻomia le tele o le mana ma le faʻagaioiga vave.
O nisi faʻamatalaga i fofo faʻataʻitaʻiga o Hyperledger Fabric ma pe aisea e aoga ai i lenei auala ae le o se isi itu e mafai ona maua iinei: pe iinei: .
O lea la, o le Hyperledger Fabric o se faiga fa'ale-malo moni e mafai ai ona e:
- Fa'atino faiga fa'atauva'a fa'apisinisi e fa'aaoga ai le masini fa'akonekarate atamai;
- Faʻamau ma maua faʻamatalaga mai le faʻamaumauga poloka poloka i le JSON format;
- Tuuina atu ma faʻamaonia le avanoa API e faʻaaoga ai le Pulega Tusi Faamaonia.
I le taimi nei ua tatou malamalama laʻititi e uiga i faʻamatalaga o Hyperledger Fabric, seʻi o tatou faia se mea aoga!
