Защита биткоина от несуществующих квантовых компьютеров

В последнее время часто можно услышать про квантовые компьютеры (КК), которые угрожают криптовалютам, в том числе биткоину, и вообще всей современной криптографии. На самом деле сообщество Bitcoin давно выработало технические решения для данной проблемы. Максимум, что требуется — обычный софтфорк , то есть обновление ПО. Его не проводят лишь потому, что КК стоят в книжном магазине на полке «Научная фантастика», если перефразировать известный анекдот.

No #QRPp CW #morsecode attempt for this morning's #parksontheair #pota activation. Too much #QRM #QSB on 40 meters. Not complaining as I still managed 41 contacts thanks to some wonderful hunters.

Paired the @youkits #hb1b with the #qrpguys Mini Tuner into a 40-15 #linkedefhw for the Early Bird #morsecode CW #amateurradio #hamradio #pota #parksontheair activation. The #hfbands are starting to change a bit #QSB with noise.

Tough #POTA #arksontheair activation today. Not only windy but #HFbands had lots of noise with pronounced #QSB. I felt like I was in an Allstate commercial. "Mayhem". But I did have an audience for a short spill. #AmateurRadio #HamRadio

Even in unsettled 40 meter conditions, I'm amazed of the POWER of #QRP CW #MorseCode. The #YouKits #HB1B & #putikeegmini #StraightKey worked through the #QSB #QRN tonight during the @northqrp #NAQCC Sprint #AmateurRadio #HamRadio

#HFBands were rough this morning with pronounced #QSB. Managed quite a few contacts on 40,30 and 20, meters and a few #POTA #parksontheiar #P2P like this one with Bob #WC1N @WC1N_radio CW #MorseCode #AmateurRadio #HamRadio

#solarcycle25 #geomagnecticstorms provided lots of #QSB this morning on 40, 30 & 20 meters but was able complete #Morsecode #pota #parksontheair activation and eke a #QSO with #TO8FP. My @Buddipole Deluxe setup as a #buddistick performed well with 3 watts from #HB1B #amateurRadio #hamradio

Horrendous day but GREAT time during today's #pota #parksontheair activation. An EXCELLENT chance to sharpen my listening skills through the #QSB on 40 meters. I felt like "Seaman Jones" in "The Hunt for Red October". "I Can Bag Him" #morsecode #AmateurRadio #hamradio @ParksOnTheAir

#Mclass #Xclass #solarflares today created #QSB on 20,17 & 15 meters making it difficult to hear #QRP signals like this 20 meter #Morsecode #POTA #parksontheair activation with Tim #VA3UV #AmateurRadio #hamradio @POTAspots
