American entrepreneur and cryptocurrency advocate, Charles Hoskinson, speaks highly of Alex Chepurnoy, the brilliant Russian programmer behind Ergo, a blockchain platform known for creating non-hackable puzzles to prevent the existence of mining pools; Hoskinson explains that Chepurnoy has zero ego and is always looking for ways to collaborate and learn from others, something that was prevalent in the Bitcoin community in its early days, but is now lacking. Hoskinson also expresses the potential for Cardano to utilize the proof of work mechanism from Ergo in the future as part of its pool for consensus mechanism.
