Chinese Wall (Information Barrier)

The term originates from financial-services regulation requiring banks to separate sell-side advisory activities from trading and research functions. The same logic applies to expert networks managing multiple institutional clients who might be on opposite sides of a transaction.

Inside an expert network, project teams handling competing client briefs are separated by a Chinese wall: shared access to client identity is restricted, project notes are compartmentalised, and senior researchers are explicitly assigned to avoid conflicts.

The wall is enforced through technology (access controls, separate document repositories), process (no cross-team briefings on conflicted projects) and culture (clear escalation paths when a wall might be breached). External audits verify the wall's integrity.

Buyers should understand how their vendor enforces walls. If you're a hedge fund running a research thesis on a specific company, you don't want the network's PE team running a buyer's diligence on the same target simultaneously, with shared expert pool. Reputable vendors document their wall architecture on request.
