Why is BTC Known as Internet Money? | Hadapsar, Pune
🗓 Saturday, 22nd August
🕙 5:00 PM - 7:00 PM
Bitcoin isn’t money because of its cryptography; it’s money because it survives an environment where every participant is assumed hostile.
To understand why Bitcoin functions as native internet money, you have to look past the surface-level protocol and examine the adversarial engineering that makes its state machine virtually impossible to alter or shut down.
