Uyazi: Isikhathi esilindelekile phakathi kwamabhulokhi amabili e-Bitcoin siphakathi kwamaminithi \(10\) amaminithi. Manje wenza ukuthengiselana okubalulekile kwe-Bitcoin futhi ulinde ngokulangazela ukubona ukuthi ivela nini futhi nini kubhlokhi elandelayo:
e50bfacc95975a4e7545d83d8954645f
Njengoba ungazange uhlole ukuthi ibhulokhi yangaphambilini yaqedwa nini, empeleni ulindele isilinganiso \( \frac{t}{2} = \frac{10}{2} = 5 \) imizuzu yesikhathi sokulinda. Ngemuva kokuthi \(5\) imizuzu emide isiphelile, hlola ukuthi ibhulokhi yokugcina iqedwe nini ngempela:
e50bfacc95975a4e7545d83d8954645f
Ibhulokhi yokugcina bese iqediwe kakade emaminithini angu- \(7\) edlule. Manje njengoba usulwazi lolu lwazi, isikhathi esilindelekile siyashintsha ukusuka kumaminithi angu- \(5\) ukuya kunani eliphelele \(10\) lamaminithi. Lokho kusho ukuthi: Emaminithini angu- \(3\) cishe kuzoba manje. Ukhipha umyalo ngokuphindaphindiwe. Futhi ulinde. Ngemva kweminye \(10\) imizuzu uthola umuzwa wokuthi kukhona okungalungile.
Kodwa-ke uyakhumbula lokho Indida yokulinda:
Uma amabhasi egijima njalo \(t\) imizuzu ngokwesilinganiso, isikhathi sokulinda sesikhathi sokufika esingahleliwe esitobhini sebhasi asihambisani \(\frac{t}{2}\) amaminithi, kodwa esimweni sokusatshalaliswa okukhulu. amabanga \(t\) .
Izehlakalo ze-Bitcoin block ziyinqubo ye-Poisson ngakho-ke zisakazwa ngokucacile. Njengoba izinqubo ze-Poisson zingenankumbulo, ibhulokhi elandelayo nayo iqedwa ngemizuzu \(10\) ngokwesilinganiso. Lokho kusebenza njalo - noma ngabe sesilinde isikhathi eside kangakanani. Izinga lokungakhumbuli lisebenza emuva naphambili ngesikhathi.
Kungenzeka kanjani lokho?
Ukuze senze lokhu, sicabangela izitatimende ezimbili ezilandelayo:
- A) Isikhathi sangempela sokulinda esimaphakathi phakathi kwamabhulokhi amabili \(10\) imizuzu, hhayi \(20\) imizuzu.
- B) Uma kukhethwa iphuzu lesikhathi esingahleliwe, silindele ukuthi ibhulokhi elidlule \(10\) lamaminithi esikhathini esidlule kanye nebhulokhi elandelayo \(10\) imizuzu esikhathini esizayo. Ngakho-ke singalindela isikhathi sokulinda \(20\) imizuzu phakathi kwamabhulokhi.
Sihlola zombili izitatimende.
Ukuze senze lokhu, siqala ngokukhipha idatha efanele, ikakhulukazi izikhathi lapho amabhulokhi aqedwa khona, efayeleni le-TXT ( elizokwenziwa nge-node egcwele endaweni esekelwe ku- bitcoind ):
e50bfacc95975a4e7545d83d8954645f
Lokhu kusinika ifayela lombhalo elilandelayo , manje esesilicubungula ngokuqhubekayo futhi siligcina ku-/ time.txt . Okulandelayo Rust hlelo ukusetshenziselwa lokhu ifayela /Cargo.toml:
e50bfacc95975a4e7545d83d8954645f
Ifayela /src/main.rs liqukethe ingqondo yokuhlola yangempela:
e50bfacc95975a4e7545d83d8954645f
Sifaka ukuncika, sakhe uhlelo futhi siluqale:
e50bfacc95975a4e7545d83d8954645f
Ngempela, zombili izitatimende ziyiqiniso lapho sihlaziya okukhiphayo:
e50bfacc95975a4e7545d83d8954645f
Lokhu kungabuye kuchazwe ngendlela enembile ngale ndlela elandelayo: Uma izikhathi zebhulokhi zihluka kakhulu, isikhathi esithile sokulinda siyahluka - uma senza okwenziwayo endaweni engahleliwe ngesikhathi, amathuba aphezulu okuthi sizogcina sisesikhathini lapho isikhathi sokulinda side kunemizuzu eyi-10 kungenxa yokuthi lezi zikhawu nazo zithatha isikhala esiningi emugqeni wesikhathi ngenxa yesikhathi eside.
