According to CertiK co-founder Ronghui Gu, who spoke with Cointelegraph, the year 2023 brought "positive progress" in #blockchain security.

Throughout 2023, more than 1.8 billion dollars in digital assets were lost in 751 security incidents. Although this is still a significant amount, it represents a 51% decrease compared to 2022, when hackers and other incidents led to losses of 3.7 billion dollars.

 This information comes from the annual report of #CertiK , a company specializing in blockchain security, titled "Hack3d: The Web3 Security Report 2023." The report, which addresses the state of Web3 security over the past year, was compiled on January 3.

 The report notes that the largest losses were recorded in the third quarter of 2023, exceeding 686 million dollars. The most costly vector of attack was the compromise of private keys, with over 880 million dollars lost in 47 incidents.

 In terms of individual blockchains, Ethereum recorded the highest losses. According to CertiK, losses in the Ethereum network amounted to 686 million dollars across 224 incidents, averaging 3 million dollars per incident. In contrast, the BNB Chain recorded 387 security incidents, but the total losses were only 134 million dollars, significantly less than Ethereum.

 The report also highlights the problem of interoperability between blockchains in the cryptocurrency sector. Losses due to security breaches affecting multiple blockchains reached nearly 800 million dollars.

 Ronghui Gu, co-founder of CertiK, expressed optimism about the progress in blockchain security in 2023 and hopes for a further reduction in losses in 2024. Gu attributes the 51% decrease in losses to the broader bear market, which led to decreased token valuations and treasury values. Gu believes that if losses remain low during a bull market, it will indicate that the Web3 sector is "learning from its security lessons."
