Binance, the world’s largest cryptocurrency exchange, has been working to improve the transparency of its reserve B-tokens following years of mismanagement. In late January, it was discovered that Binance stored token collateral with user funds in the same wallet, leading to concerns about the transparency of its reserves.
New Semi-Automated Process
To address these concerns, Binance has set up a partially-automated process that ensures the B-tokens are “always transparently backed”. This is achieved through a system that only allows the minting of new coins to take place after collateral has been added to the appropriate wallet.
The company has been moving the collateralized assets to dedicated wallets over the past few weeks, which show the 1:1 backing of each asset.

Potential for Regulatory Concerns
The move may be a PR exercise to increase reserve transparency amid a regulatory crackdown on centralized exchanges.
However, some experts are skeptical that the semi-automated system will be sufficient to address all concerns. Conor Ryder, a research analyst at blockchain data firm Kaiko, said that while the new system gives Binance the ability to intervene if an incident were to impact the B-token reserves, it is not an ideal fully-automated system.
Implementing zk-proofs
On Feb. 10, Binance improved its proof-of-reserves system by implementing zero-knowledge proofs in the form of zk-SNARKs. This cryptographic method of proving the validity of a statement or data without revealing the data or statement itself enables users to check that each account’s total net balance is non-negative and that all user assets are part of Binance’s claimed total net balance.
Bottom line is Binance is taking steps to improve transparency and address concerns about its reserves. While experts have raised some concerns about the effectiveness of the new system, the implementation of zk-proofs is a positive development in the company’s efforts to increase transparency and regain trust.
