I-Bitcoin ihamba ngeenkwenkwezi. Nantsi indlela.
I-Bitcoin iye yathandwa kakhulu kwihlabathi, kodwa kuthekani kwithuba? Omnye wabaphuhlisi abakhulu benkqubo ye-bitcoin sele isebenza kwinkqubo engayenza inkolelo yenethiwekhi ye-bitcoin, phezulu kwi-orbit.
Ebizwa ngokuba yi-BitSat, le nkqubo iya kubona i-satellites ezingama-24 ezikhutshwe kwi-space, ukubonelela ngehlabathi jikelele. Ngamanye ama-satellites aya kusebenza njenge-nutcoin node, ukucwangcisa idatha kwi-network ye-bitcoin.
Kodwa kutheni na?
Ulwazi lufuna ukukhululeka
Xa ekuqaleni wayepapashe le ngcamango, emva kukaNovemba 2013, i-bitcoin enkulu uJeff Garzik yathi "ulwazi lufuna ukukhululeka". Wayefuna enye inethiwekhi yokunxibelelana ye-bitcoin.
"Enye yeendlela esinokugcina ngayo i-bitcoin enempilo kunye nekhululekile ifumana iindlela ezongezelelweyo zokusabalalisa idatha ye-blockchain. Oku kunika amandla xa umnatha wenethiwekhi we-P2P uhlaselwa, "watsho ngelo xesha.
Ziziphi iintlobo zokuhlaselwa ezinokuba ngaba? Ukuhlaselwa okufanayo kumnatha we-bitcoin kukuhlaselwa kwe-Sybil. Kwimeko enjalo, iqoqo leempawu eziqhutyelwa yinkampani yesithathu zijikeleze i-node yexhoba kwaye idlulisa ulwazi olungamanga. Ukuhlaselwa kwe-Sybil kungasungulwa kumanqaku amaninzi ngokukhawuleza, kudala ukudideka nokuvelisa ulwazi olubuxoki kwinethiwekhi.
Enye yeendlela esinokugcina ngayo i-bitcoin enempilo kwaye ikhululekile ifumana iindlela ezongezelelweyo zokusabalalisa idatha ye-blockchain.
Ukuhlaselwa kwe-Sybil kungasetyenziselwa zonke iintlobo zobubi.
Oku kufaka nje ukukholisa intanethi ongayichitha i-bitcoin xa unayo, ngokungafuni ukubuyisela iibhloko kunye nokuthengiselana kwi-node yakho ye-Bitcoin, ukukhupha ngokukhawuleza kwi-intanethi.
Enye indlela yokusombulula le ngxaki kukudala umthombo omnye wenyaniso ngolwazi lwe-bitcoin.
Umsebenzisi wenethwekhi uya kuqinisekisa ukuba ulwazi oluvela kwi-satellites luya kuchaneka. Ukuzibeka endaweni kwakuba yindlela yokufumana loo nkcukacha kubantu abaninzi ngangokunokwenzeka kuba iipatellithi ziyakwazi ukubethelwa ulwazi kwiindawo ezibanzi.
Nganye yezi satellites ziyakusindisa yonke i-bitcoin blockchain, ihlinzeke ngokukhusela kwi-network bitcoin network. Baza kufumana ukuhlaziywa kunye nedatha entsha ye-blockchain kwizikhululo eziphantsi komhlaba, ngexesha lemizuzu eyi-15 edlulileyo. Baya kuthi baqinisekise ngokuzimeleyo ukuba ulwazi luqinisekisa ukuba luchanekile.
Bitcoin kwi cube
I-Satellites ixabisa inani elimangalisayo lokuqalisa, kodwa enye indlela yokugcina iindleko ezantsi kukukwenza ukuba kube mncinci kunye nomgangatho osemgangathweni. Inkampani emva kweBitSat, i-Dunvegan Space Systems, isebenzisa inqanaba elincinane lefomathi ye-satellite, ebizwa ngokuthi yiCubeSat. Le yecube, elinganisa i-10cm x 10cm kuphela.
I-satellite nganye iya kuhlala emihlanu kwiminyaka. UDunvegan uqikelela ukuba unokufumana i-satellite yodwa kwi-$ 1m, okanye i-$ 19 kwinqanaba. Enye indlela yokwenza oko kukuguqula ukuqaliswa kwezi satellithi ezincinci kwii-payload ezinkulu.
Oku kunokuzwakala ngathi inzululwazi, kodwa uGarzik unzulu malunga nesicwangciso, kwaye isigaba sokuqaliswa sihleli ngo-2016.
I-Dunvegan isayine isivumelwano kunye ne-Deep Space Industries, eya kuba yakha i-nanosatellites. Ezi satellites ezine zikulindeleke kwisigaba sokuqala sokuqala, kunye nokunye ukulandela emva koko.
Ingcamango yomthombo omnye wolwazi oluchanekileyo kubalulekile njengoko inethwekhi ibaluleke ngakumbi kubasebenzisi bayo. I-network yokubeka inethiwekhi ye-satellite ngumzekelo omhle-nabani na abafuna ulwazi oluchanileyo lwe-geolocation kufuneka baxelele ummkeli wabo esibhakabhakeni, kwaye ufunde iimpawu ezisuka kwi-network ye-GPS, ukuze ziphume apho zikhona.
Ukuba kwaye nini le nethiwekhi isekugqibeleni, umthengisi wesithathu uya kunika ulwazi lwe-downlink kwii-satellites. Abathandi be-bitcoin benene bangakwazi ukusekela zabo abafumana i-satellites, nangona kunjalo, ukuba bafumane ulwazi ngokuthe ngqo ngaphandle kokuhlawula.
