Gate Unveils Proof of Security With 104.58% Cold Coverage
By Nodora News ·
Gate launched Proof of Security (PoSEC) on Nov 5, saying cold storage covered 104.58% of customer assets in a Nov 4 snapshot after the Binance hack.
Gate became the first major cryptocurrency exchange to publicly launch Proof of Security (PoSEC) on November 5, 2026, saying a November 4 snapshot showed cold storage covering 104.58% of customer assets — enough, on the exchange's methodology, to cover every user balance even if hot wallets were emptied.
The announcement, posted at 10:00 UTC on Gate's site and discussed by founder and CEO Lin Han in a CoinDesk interview the same day, lands about a week after Binance's record ~$6.3 billion hack. Gate frames PoSEC as a complement to Proof of Reserves (PoR): PoR shows assets exist; PoSEC shows how they are stored and whether offline holdings alone could absorb a total hot-wallet loss.
Key takeaways
- Gate launched PoSEC on Nov 5, 2026 (10:00 UTC), calling itself the first exchange to publish the standard publicly.
- Snapshot at 00:00 UTC Nov 4: cold-storage coverage ratio 104.58%; cold storage 88.26% of total assets; hot wallets 11.74%.
- Latest PoR (as of Oct 18, 2026): total reserves about $8.688–8.69 billion, overall reserve ratio 118.49%.
- An independent third-party audit of the PoSEC figures is underway; the report is not published yet and will appear on Gate's site when finished.
- CEO Lin Han told CoinDesk PoSEC cannot verify passwords, key management or access controls, and does not erase the security vs. fast-withdrawal trade-off.
What Gate announced
Gate said PoSEC measures whether cold storage alone could cover all customer balances if every internet-connected (hot) wallet were lost. Hot wallets hold funds used for routine deposits and withdrawals and stay online; cold storage, in Gate's definition, holds assets that are not used for day-to-day transfers, sit offline or under independent custody, require multi-party authorization to move, and can be independently verified.
Under that definition, cold storage can include offline digital assets and traditional assets such as stocks and U.S. Treasuries held by independent custodians. Gate notes those custodied traditional assets are not on-chain cold wallets, so reported cold storage may exceed balances visible on public blockchains.
Founded in 2013 and serving more than 60 million users, Gate has published open-source PoR since 2020 (Merkle Tree proofs, later zk-SNARKs). Its broader stack, per the announcement, includes hot/cold segregation, multisig, multi-party computation (MPC), dynamic risk monitoring and zero-trust access controls.
How PoSEC differs from Proof of Reserves
Proof of Reserves answers whether an exchange holds enough assets to match customer liabilities. Gate's Oct 18 PoR put reserves near $8.69 billion with a 118.49% overall reserve ratio. Other large venues, including Binance, Kraken and OKX, already publish reserve-style reports.
PoSEC asks a different question: if the hot wallet were wiped out, would cold storage still cover user assets? A coverage ratio at or above 100% means, under Gate's formula (cold storage ÷ user assets), cold holdings alone would be enough. Han told CoinDesk: "Proof of Reserves (PoR) shows the assets exist, and PoSEC shows how they're stored and whether they're protected."
Han said hot-wallet exposure is covered by excess reserves above user assets, and that Gate wants other exchanges and regulators to consider adopting PoSEC without calling for a legal mandate.
The numbers: 104.58% cold coverage
Gate's PoSEC page and announcement cite these figures from the 00:00 UTC November 4, 2026 snapshot:
- Cold storage coverage ratio: 104.58%
- Cold storage share of total assets: 88.26%
- Hot wallet share: 11.74%
The exchange says the data is being checked by an independent auditor for asset authenticity and control, valuation and reporting basis, and coverage-ratio math. No audit report has been published yet; Gate says it will post the report on its website when the review is complete.
Why it matters after the Binance hack
Binance's October 29 breach showed that reserve proofs alone do not stop theft from hot wallets. Binance had published PoR, yet online-wallet assets were stolen; it later said it set aside about $6.34 billion for users. Withdrawals have reopened in stages (69 more token pairs), and U.S. supervisors have been asking banks about fallout.
Gate said recent breaches made a public launch appropriate. Han acknowledged limits: PoSEC does not prove password hygiene, private-key handling or access controls, and it does not erase the trade-off between offline security and fast withdrawals. "It doesn't necessarily eliminate the trade-off. What it does is make it manageable," he told CoinDesk.
Market backdrop and what to watch
At OKX prices around this write-up, bitcoin (BTC) traded near $76,239 (−5.7% over 24 hours from the open), ether (ETH) near $2,242 (−7.9%), and BNB near $694.66 (−3.6%). Live markets: Nodora Charts.
What to watch next:
- Publication of Gate's independent PoSEC audit report on its website.
- Whether other exchanges disclose cold-vs-hot coverage ratios in similar form.
- Any regulator or industry-group response to Han's call for voluntary adoption.
- Further recovery and custody disclosures from venues hit by recent hot-wallet breaches.
PoSEC does not replace operational security. It adds a public ratio for the question Binance's hack put back on the table: not only whether reserves exist, but whether enough sit beyond an emptied hot wallet.
