Educational Byte: What Is a Sybil Attack in Crypto Networks?

Unlike banks, crypto networks run without a central boss and without access requirements. Anyone with a device and Internet can create their own wallet in minutes.

Crypto is pseudonymous and open… and that, without proper protection, could cause bad things like a Sybil attack.
