Therefore, the shards forming process is supposed to be resistant to collusion by malicious actors. This also helps speed up block confirmation, resulting in transaction finality times of about 2 seconds.Īs an additional security measure, the choice of nodes for the shards is made using a Verifiable Random Function, which makes it unpredictable. Moreover, this setup is secured using the modified Byzantine Fault Tolerance algorithm based on Effective Proof-of-Stake (EPoS) consensus protocol, unlike some other blockchain platforms that use sharding but employ Proof-of-Work. All of the shards can validate their own set of transactions simultaneously, thus improving speed. To provide scalability, Harmony uses sharding - a technology splitting the network into segments, or shards. Harmony was founded in 2017 by Stephen Tze, who had previously worked for Microsoft, Google, and Apple. Harmony (ONE) is a native token on the Harmony platform - a solution aimed to provide scalability for the blockchain developers, to give them tools to build and deploy their dApps. Meanwhile, beleaguered crypto hedge fund Three Arrows Capital could be set to default on a $660 million loan from brokerage firm Voyager Digital. Crypto lenders Celsius and Babel Finance put a freeze on withdrawals after a sharp drop in the value of their assets resulted in a liquidity crunch. The heist adds to a stream of negative news in crypto lately. Wormhole, another popular bridge, lost over $320 million in a separate hack a month earlier. The Ronin Network, which supports crypto game Axie Infinity, lost more than $600 million in a security breach that took place in March.

It follows a series of notable attacks on other blockchain bridges. Harmony was not immediately available for comment when contacted by CNBC.

Some researchers speculate the breach was the result of a 'private key compromise,' where hackers obtained the password, or passwords, required to gain access to a crypto wallet. The security of the Horizon bridge hinged on a 'multisig' wallet that required only two signatures to initiate transactions. However, one investor had raised concerns about the security of its Horizon bridge as far back as April. Harmony has not revealed exactly how the funds were stolen. 'As a result, these services hold large volumes of cryptoassets.'

'In order for individuals to use bridges to move their funds, assets are locked on one blockchain and unlocked, or minted, on another,' Symington said. Like other facets of DeFi, which aims to rebuild traditional financial services like loans and investments on the blockchain, bridges have become a prime target for hackers due to vulnerabilities in their underlying code.īridges 'maintain large stores of liquidity,' making them a 'tempting target for hackers,' according to Jess Symington, research lead at blockchain analysis firm Elliptic.

Harmony said the attack did not affect a separate bridge for bitcoin. In Horizon's case, users can send tokens from the Ethereum network to Binance Smart Chain. In a follow-up tweet, Harmony said it's working with the Federal Bureau of Investigation and multiple cybersecurity firms to investigate the attack.īlockchain bridges play a big role in the DeFi space, offering users a way of transferring their assets from one blockchain to another. 'We have begun working with national authorities and forensic specialists to identify the culprit and retrieve the stolen funds,' the start-up said in a tweet late Wednesday.
