Supply surged by 3 trillion dollars, and the established public chain Harmony is in jeopardy again
Source: Foresight News Author: Mach Original title: Hackers blasted 3 trillion ONE: The established public chain Harmony was hit by another fatal blow. In 2022, Harmony's total TVL peaked at over 1.4 billion US dollars. According to DeFilLama's latest data, its TVL is less than 170,000 US dollars. Hacker attacks are becoming the “number one killer” of cryptographic protocols. On August 12, X user Juiceberg tweeted that on-chain data showed that the Harmony protocol had been exploited, and that attackers illegally minted about 4 billion ONE tokens (worth more than 3 million US dollars) through empty blocks, accounting for 26% of its total supply. Of these, about 2.8 billion tokens were quickly transferred to exchanges during the price collapse, while Harmony's total supply end point failed to reflect this additional token issuance, causing differences between actual on-chain supply and public data. The attackers have about 115 million pieces left on the chain (about 2.9% of the minting volume), and the vast majority of the rest have either gone to exchange accounts, sold, or stored in deposit wallets. After the news was announced, ONE's price plummeted from $0.00118 to a minimum of $0.00056, and has now rebounded to $0.00078, a 24-hour drop of nearly 38%. The official Harmony response was then retweeted on the X platform. It is cooperating with the team and several related exchanges to block and freeze the funds involved; at the same time, it is promoting software patch development and evaluating network rollback options. Subsequently, the government further announced four sets of relevant wallet addresses, clearly requiring each exchange to block and freeze funds traceable to these addresses: one1uap8dx2z0qsjxqthm5flgcxkeepsz3gsrghnfnone17u300a40ll5wphd8kj5hktryhdjq3ml9f4phy4one1a5hur07z5vtvzhr35zkw8tfqedemkz8t88xgd7one1h56hkxmua0uzfv07fu04cudvtrl35u96pq47vy at around 2 p.m. bridge.harmony.one cross-chain bridge service and requires all verification nodes to immediately upgrade to the latest patch version v2026.1.1. Officially, the patch will prevent further illegal minting, and will be updated separately to handle minted tokens in the future. The relevant release notes are already available on GitHub. This is the third time in recent years that Harmony has experienced major security or technical issues directly related to token supply. In June 2022, its Horizon cross-chain bridge was attacked, losing about $100 million in assets. The US Federal Bureau of Investigation later attributed the incident to North Korea-related hacker groups. In December 2023, a bug occurred in the staking system, causing approximately 146.3 million ONE to be mistakenly minted, involving 74 addresses, of which a single address received more than 51 million tokens. Some of the tokens were then transferred to the exchange. Officials urgently issued a patch and took follow-up measures at the time. Judging from the size of the market, although this incident caused drastic dilution of supply and sharp price fluctuations, the scale of absolute losses was limited. Prior to the incident, Harmony's market capitalization had dropped to around $17 million; after the incident, it fell further back to the $12 million level, and the market value evaporated by about $5 million. Harmony's total TVL peaked at over $1.4 billion in 2022, and DeFilLama's latest data shows that its TVL is less than $170,000. According to CertiK Alert monitoring, as of around 4 p.m., the number of ONE tokens abnormally minted by the Harmony network had exceeded 3 trillion (worth approximately $2.34 billion), involving six abnormal blocks. Early attackers initially used the total supply interface to hide incremental data, and different blocks were packaged one after another, so the 4 billion increase at the time was far from real data. X account BlockWatchDog said that the attackers used Harmony's serious logical errors in cross-shard receipt verification and signature checks to falsify about 3 trillion coins in one go. Harmony is a sharded chain. Transferring coins between different shards requires...
