How about 'Protons'?
''The Oh-My-God particle was an ultra-high-energy cosmic ray (most likely a proton) detected on the evening of 15 October 1991 over Dugway Proving Ground, Utah. Its observation was a shock to astrophysicists (hence the name), who estimated its energy to be approximately 3×1020 eV (3×108 TeV, about 20 million times more energetic than the highest energy measured in radiation emitted by an extragalactic object);[1] in other words, a subatomic particle with kinetic energy equal to that of 50 Joules, or a 5-ounce (142 g) baseball traveling at about 100 kilometers per hour (60 mph).[2]
The particle was traveling very close to the speed of light[3] — assuming the particle was a proton, its speed was only about 1.5 femtometers (quadrillionths of a meter) per second less than the speed of light, translating to a speed of approximately 0.999 999 999 999 999 999 999 9951c.''
They're fast like DPOS, invisible like digital currencies & as long as the universe exists, so will Protons...just like the PTS blockchain (hopefully)!
