Le talaʻaga o le Blockchain

Taimi faitau: 3 minute

O le tekonolosi e faʻavaeina le lalolagi o cryptocurrency o le lalolagi lauiloa blockchain.
Le poloka poloka faʻatagaina tagata taʻitasi i luga o le upega tafailagi ia maua le maliega e aunoa ma le tau faʻatuatuaina o le tasi i le isi. E foliga mai e saʻo e taʻu le talaʻaga o le poloka poloka, i se faapuupuuga.

Faasino Upu

O aso muamua

O le aitia i tua atu o tekonolosi poloka na faʻamatalaina i tuā i tua o le 1991, ina ua suʻesuʻe le au suʻesuʻe Stuart Haber ma W. Scott Stornetta latou faʻalauiloaina se computationally aoga fofo mo le makaina numera numera ina ia latou le mafai ona backdated pe faʻalavelaveina.

O le faiga faʻaaoga se filifili cryptographically saogalemu o poloka e teu pepa faʻailoga i le timestamp ma ua i ai i le 1992 le galuega faʻafouina ma Merkle laau, faia ia sili atu lelei ma faʻatagaina oe e aoina tele pepa i le tasi poloka. E ui lava o lenei toʻalua suʻesuʻe o se taumafaiga tele, o lenei tekonolosi na tumau pea le faʻaaogaina ma ua maeʻa le pateni i le 2004, fa tausaga ae le i fanau mai Bitcoin.

Faʻamaoniga o Galuega toe faʻaaogaina

I le 2004, saienitisi komipiuta ma le tagata faʻagaeʻetia crypto Hal Finney (Harold Thomas Finney II) faʻalauiloaina se faiga e taʻua o le RPoW, Reusable Proof Of Work. O le faiga na galue e ala i le mauaina o se le mafai ona fesuiaʻia se faʻailoga poʻo se le mafai ona faʻaleleia Hashcash-faʻavae "faʻamaoniga o galuega" ma i le toe maua ai se RSA saini faʻailoga e mafai ona fesiitaʻi mai lea tagata i lea tagata.

RPoW foʻia le faʻalua faʻaaluina o faʻafitauli e ala i le taofia o le umiaina o faʻailoga faʻailoga i luga o se faʻatuatuaina tautua, fuafuaina e faʻatagaina ai tagata faʻaoga i le lalolagi atoa e faʻamaonia lona saʻo ma le faʻamaoni i le taimi moni.

E mafai ona tatou mafaufau ia RPoW o se muamua faʻataʻitaʻiga ma o se taua muamua laʻasaga i le talaʻaga o tagi.

Bitcoin fesootaiga

I le faaiuga o le 2008, tasi na faasaoloto paʻepaʻe, o se suʻesuʻega pepa, lea na faʻaulufaleina ai le peer-to-peer eletise faʻatupeina eletise faiga - taʻua o Bitcoin. Na lafoina i se faʻailoga meli lisi e se tagata poʻo se kulupu e faʻaaoga ai le igoa o le Satoshi Nakamoto.

O lenei poloketi na faʻavae i luga o le Faʻamaoniga o galuega Hashcash algorithm, ae le o le faʻaaogaina o masini komepiuta fuafuaina e pei o le RPoW, Bitcoin faʻalua faʻaaluina puipuiga na saunia e le tuʻufaʻatasia o tupulaga-to-peer maliega faʻapitoa e siaki ma faʻamaonia fefaʻatauaiga. I ni upu faigofie, Bitcoins e "maina" mo se taui Faʻaaogaina le faʻamaoniga-o-galuega auala e tagata taʻitoʻatasi minera ma ona faʻamaonia e nodes fesootaiga tufatufa.

Bitcoin na fanau ia Ianuari 3, 2009.

O le poloka muamua o Bitcoin na eliina e Satoshi Nakamoto, ma le taui e 50 Bitcoins. O le muamua mauaina Bitcoin o Hal Finney, o le na mauaina le 10 Bitcoins mai Satoshi Nakamoto i le muamua Bitcoin fefaatauaiga ia Ianuari 12, 2009.

Ethereum network

I le 2013, Vitalik Buterin, o se polokalame ma o se tasi na faavaeina le mekasini Bitcoin, na taua ai e manaʻomia tele e Bitcoin le gagana tusitusi (coding, code building) e fausia talosaga tufatufa. O le le mafai ona maua se finagalo autasi o le afioʻaga, na amata ai e Vitalik ona atiaʻe se poloketi fou faʻavae tufatufaina o poloka poloka, ma faʻaigoa ia Ethereum. E pei ona ia folafolaina, o lenei fesootaiga fou sa i ai se vaega tusitusi i totonu o ia valaauina Konekarate Faʻatau.

O Konekalate Poto o ni polokalame poʻo ni tusitusiga e tufatufaina ma faʻatinoina i luga ole poloka Ethereum, ma e mafai ona faʻaaogaina e faʻatino ai se feutanaiga pe a fai e iai ni tuutuuga e ausia. O konekalate atamai e tusia i gagana faʻapitoa e faʻatulagaina ma tuʻufaʻatasia i le bytecode, o le masini tuʻufaʻatasia o Turing-complete (poʻo le Turing-tutusa) e faʻaigoaina o le Ethereum Virtual Machine (EVM) e mafai ona faitau ma faʻatinoina.

Developers, o le fatu pao o lenei poloka poloka, mafai foi ona fausia ma lolomiina tusi talosaga o loʻo tamoʻe i totonu o le Ethereum poloka. O nei tusi apalai e masani ona valaauina DApps (tufatufaina apalai) ma mafai ona i ai eseʻese fomu mai le tasi i le isi, pei lava o polokalama i luga o la tatou telefoni: sosaiete ala o faasalalauga polokalama, petipeti talosaga ma faʻafesuiaʻi tautupe talosaga.

Ole igoa ole Ethereum e taua ole Eteru (ETH). E mafai ona fesiitaʻi i le va o teuga tupe ma e faʻaaoga e totogi ai komisi mo le malosiaga faʻatulafonoina na faʻaaogaina peʻa faʻatinoina ni konekalate atamai.

Blockchain tekonolosi ua faʻateleina le totonugalemu o le faʻalogo, ua tosina mai le tele o faʻalogo i le autu, ma ua uma ona faʻaaogaina i le tele o ituaiga o talosaga, e le gata i cryptocurrency.
