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.

Chainalysis CEO Michael Gronager joined us for a discussion of what happened and what role transaction monitoring will play in the future. We dove deep into the tension between the desires for user privacy and the requirements to achieve integration into existing financial services.

Topics covered included:

- How Chainalysis' nodes caused problems for breadwallet

- What damage a large scale sybil attack could really do to Bitcoin

- The role transaction monitoring will play to achieve Bitcoin integration in existing systems

- Why transaction-related blockchain analysis does not threaten Bitcoin's fungibility

- The best way users can protect their anonymity
