Justin Sun, founder of TRON, has publicly criticized Coinbase for its refusal to adopt Proof of Reserves (PoR)—a transparency measure widely embraced by other major crypto exchanges. Sun's remarks come in response to Coinbase CEO Brian Armstrong's assertion that annual audits suffice for institutional trust, dismissing the need for PoR.
Justin Sun's Call for Transparency
Sun argues that PoR is a critical safeguard against liquidity crises, citing the FTX collapse as a prime example of how opaque financial practices can lead to disaster. He emphasizes that being a publicly traded company does not eliminate bankruptcy risks, pointing to Signature Bank's failure as evidence.
"When all exchanges implement PoR, Coinbase’s claim that it’s 'infeasible' puzzles the community. Revealing wallet addresses isn’t complex, and audits alone can’t prevent disasters—FTX proved that. PoR is a necessary step for self-regulation," Sun stated.
Industry-Wide Adoption of PoR
After FTX's November 2022 collapse, exchanges like Binance, Kraken, and OKX began publishing PoR reports to reassure users. Binance’s former CEO CZ championed Merkle-tree PoR, though critics like Kraken’s Jesse Powell caution it can create a false sense of security.

Coinbase’s Counterargument: Institutional Needs Over PoR
Armstrong defends Coinbase’s stance, stating that institutional clients prioritize annual audits (conducted by Deloitte) over public PoRs. He also addressed concerns around cbBTC, Coinbase’s new Bitcoin wrapper, which lacks PoR:
"Institutional money flows into Bitcoin require privacy. Dusting addresses or sharing client reserves isn’t our role."
Community Backlash Over cbBTC
Critics, including Sun, label cbBTC a "trust-me Bitcoin", warning that government seizures could jeopardize holdings. An X user Duo Nine echoed this:
"Coinbase admits you must trust their word—no PoR, no proof of backing for cbBTC. Overprinting = FTX 2.0."
Limitations of Proof of Reserves
While PoR enhances transparency, experts note gaps:
- Liabilities aren’t disclosed, making reserve snapshots misleading.
- Risk management varies across firms, leaving users in the dark until crises hit.

FAQ Section
Q: Why is Proof of Reserves important?
A: PoR verifies an exchange holds sufficient assets to cover user balances, preventing FTX-like collapses.
Q: Does Coinbase’s audit replace PoR?
A: Audits ensure compliance but lack real-time transparency. PoR offers ongoing accountability.
Q: What’s the risk of cbBTC?
A: Without PoR, users rely on Coinbase’s integrity—raising potential seizure or insolvency risks.
Q: Can PoR fully prevent exchange failures?
A: No. It’s one layer of transparency; liabilities and management practices also matter.
Conclusion: A Push for Deeper Transparency
The debate underscores a broader industry need: robust, real-time financial disclosures. While Coinbase prioritizes institutional demands, community pressure for PoR adoption grows louder. As Sun frames it, "Self-regulation starts with transparency."
