first_img Privacy Public Chain Iron Fish: Will terminate remaining support, confirm inflation vulnerability

The privacy public chain Iron Fish officially announced that it will formally terminate all remaining support for the Iron Fish network on that day. The team stated that several days ago, they observed unusual activities involving wIRON and the cross-chain bridge ChainPort. After collaborating with ChainPort and reviewing its logs, they confirmed that the reason was an inflation vulnerability present in the Iron Fish blockchain itself.The official statement indicated that the vulnerability can be traced back to a commit in the implementation of the Merkle tree in early 2019. At that time, the developers implemented a standard Merkle tree, but due to a detail difference in the calculation method of the ticket nullifier, attackers were able to spend the same ticket multiple times, subsequently aggregating the related tickets and transferring them out through the ChainPort cross-chain bridge. The official statement noted that this code path had been included in both external and internal audit scopes, but it was not discovered during the review.The team stated that they submitted a vulnerability patch before shutting down and archiving the ironfish codebase, and attached an explanation in the related PR. The Iron Fish mainnet was launched on April 20, 2023, and the developing company was later acquired by Coinbase; the foundation announced a transition to maintenance mode in April 2026.

Yili Hua: Patiently wait for the best bottom-fishing opportunity, still optimistic about quality AI stocks and crypto assets

Liquid Capital founder Yi Lihua stated that the trading process is not easy. Previously, while maintaining a bullish outlook, the market experienced multiple corrections; after the price rose to $86,000, he insisted on looking for corrections, during which there were also several rebounds, even reaching $87,000. In the past month, the price has repeatedly fallen back to the $80,000 to $81,000 range before quickly rebounding to the key position of $84,000.He emphasized that both the rise and the correction are not linear, and one should not always think about trading, but rather adhere to the principle of "looking for corrections without shorting," patiently waiting for the best bottom-fishing opportunity. He mentioned that he founded and manages three different funds, focusing on cryptocurrency investment, cryptocurrency trading, and AI technology, with cryptocurrency trading being the most challenging, described as "a practice against human nature." He raised the question of whether investors will still have the confidence to bottom-fish in the face of the upcoming extreme panic, which is worth contemplating.Regarding the future market, he views what he calls Buffett being trapped in Google and Duan Yongping being trapped in Pop Mart as a temporary phenomenon, and believes that AI will continue to create miracles, monetary expansion will not stop, and high-quality AI stocks and cryptocurrency assets remain his favored trend direction.
