Cryptographer and specialist in the theory of computers and systems Nick Szabo, together with researcher Elaine Ou from Stanford University, presented a project in which they test the conduct of transactions in the network of bitcoins using radio waves. The presentation took place last weekend during the Scaling Bitcoin conference in San Francisco, Bitcoin.com reports.
According to the authors of the concept, despite the fact that at the moment the bitcoin network is sufficiently secure to protect, there are fears that in the future it will be attempted to attack or block through firewalls, network blocks or other means that may be used by governments or monopolists in area of telecommunications.
Bitcoin radio wave transaction
To solve this problem, Szabo and Ou suggest using Skywave communication tools that use the ionosphere, a layer of the Earth's upper atmosphere, which serves as a kind of mirror for radio waves of a certain length, including those that can be used to carry out bitcoin transactions.
To do this, we are going to propose using skywave communication using the ionosphere where the sun hits the upper atmosphere of the earth near space with ultraviolet radiation — the layer it ionizes particles and creates this layer that acts as a mirror for certain radio wavelengths like the kind we want to use. The radio community — the two regimes we are interested in, in the radio community it’s near-vertical incidence skywave, this is the 70 degree angle there, it’s nearly vertical. You get a range of about 5 or 600 km. The most reliable frequency are 40-80 m. That’s what we’re targeting.
Using the GNU Radio software tool to demonstrate the modulator involved in the testing, Szabo and Ou conducted a loop test with 70 cm antennas for the transmitter, using also the HackRF-1 device and 21 Bitcoin Computer.
