Ethereum co-founder Vitalik Buterin has urged crypto exchanges to focus on surviving cyberattacks rather than gaining market share over the next two years. He warned that security threats now center on the systems managing customer funds, not just blockchain code.

Speaking to Moneycontrol during his visit to India for Devcon 8, Buterin said crypto exchanges and custodians are moving toward what he called “bunker mode.” His comments followed Binance’s October 29 breach, which affected roughly $6.34 billion in digital assets.
Why Buterin Wants Crypto Exchanges on Defense
According to Buterin, many of the latest cyberattacks have focused on the user interface and centralized parts of the system. He argued that smart contract attacks have become rarer recently, but cybercriminals still attack through application weaknesses and vulnerabilities related to wallet access.
It is expected that crypto exchanges, custodians, and large financial organizations will focus on security more than on growing the business. According to Buterin, the main thing is not to interrupt operations and secure funds from other cyberattacks.

Moreover, Buterin highlighted another advantage of using on-chain activity. Binance Smart Chain is given as an example, which allows crypto exchanges to use smart contracts and blockchain security instead of centralized solutions.
In addition, Buterin suggested that people pay attention to the way their assets are secured. It is better to use multisignature wallets, where two signatures are required to confirm the transaction.
How Binance’s $6.34B Hack Raised Security Concerns
The breach of October 29 illustrated the means through which attackers could infiltrate into the operations of wallets through the employees’ systems. Binance noted that the breach entailed the use of hacked computers, stolen credentials, and an internal AI tool that allowed the attackers to penetrate further.
In its report issued on November 3, Binance stated that an attacker had exploited the stolen permissions for deploying a container and malicious script. According to the company, around $6.34 billion of assets had been affected.
Binance stated that approximately $2.85 billion of assets had been frozen or stopped by November 3. The company added that around 98% of the impacted token assets had been replenished by October 31, with the financial losses not falling to the customers.
On October 31, the FBI blamed the theft on the North Korean hackers known as TraderTraitor. It noted that the investigation found that the stolen funds had been changed into Ether mainly and that additional laundering would be done through decentralized platforms.
Buterin noted that frequent thefts by North Koreans could make regulators impose strict rules on crypto exchanges. He mentioned that the regulators might ask the companies to be more careful in handling digital assets in future.
Regulators in South Korea have also urged crypto exchanges to improve their cold wallet protection and verification process following the Binance breach.
What Lean Ethereum Means for Network Security
Apart from exchanges for crypto, Buterin introduced Ethereum’s Lean Ethereum roadmap. This roadmap will enhance performance while making decentralization and security important components of any upgrade.
Zero-knowledge proofs, artificial intelligence, and formal verification are part of the roadmap. Buterin stated that AI could speed up the process that otherwise might take more than twenty years using previous methods of development.
Formal verification is described as a method of testing to see if there is proper behavior of code and algorithms. Conservative hash-based cryptography is planned to be used at the bottom layer of Ethereum.
Regarding the second layer networks, Buterin mentioned that scaling is no longer enough of an advantage. The examples of high performance, decentralized finance, and privacy were Lighter and Aztec.
In addition, there are use cases for blockchain to document supply chains, healthcare, and manufacturing processes. Entities can disclose the cryptographic proofs without revealing the private data.
Buterin referred to the growth of tokenization of physical objects on Ethereum over the last eighteen months. Buterin mentioned that the traditional finance sector still has the need for identity verification, but blockchain technologies can minimize the need for intermediaries.
