Michael Gronager: Chainalysis – Surveillance and the Path to Mass Panic

When spinning up a few hundred data-gathering Bitcoin nodes prevented some breadwallet users from transmitting bitcoin transaction, a minor panic quickly erupted about the Bitcoin compliance startup Chainalysis and their supposed sybil attack on the Bitcoin network.
