White Hat Discovers Massive Vulnerability in ETH to Arbitrum Bridge

Borrowers may instantly borrow up to 40% of the collection’s floor price of the posted NFT and will pay a variable interest rate depending on the utilization of the ETH deposited in the protocol, similar to mechanisms used by fungible token lending protocols like Aave. The protocol uses a ‘health score’ to evaluate the riskiness of loans, with liquidations beginning if a loan’s health score drops below one. In short, the loan will get liquidated when the debt plus interest reaches 95% of the collection’s floor price, a level known as the liquidation threshold. However, instead of the collateral NFT getting liquidated as soon as possible after a loan’s health score falls below one, a 48-hour auction mechanism begins. Additionally, there were further constraints on the auctions, such as requirements that bids be within 5% of OpenSea’s listed NFT floor price and above the debt amount that the NFT was collateralizing. However, Arbitrum’s updated protocol applies to this problem an elegant solution called “pipelining.” Pipelining allows network validators to continue processing transactions for final approval even if a previously-processed transaction is under dispute.

Reddit intends to utilize the ultra-low-cost transactions and the maximum security offered by Nova. Still, customers often send their funds via unsupported networks, usually BEP-20 , Polygon, Cronos, Avalanche and Arbitrum.

Arbitrum which Offchain Labs launched came into the picture to salvage the situation. With Arbitrum, developers can execute unmodified Ethereum Virtual Machine contracts and Ethereum transactions all on Layer-2 while utilizing ETH Layer-1 security. Arbitrum is a highly scalable Layer-2 solution project which was designed for Ethereum smart contracts. In this week’s episode, Anna chats with Vaibhav Chellani, a bridge builder and the co-founder of Socket.

However, most believe ETHW will struggle to gain acceptance as protocols, and importantly stablecoin issuers, have pledged allegiance to proof-of-stake Ethereum, making ETHW rife with issues. Still, ETHW does have some backers such as Tron founder Justin Sun, and markets are ascribing some value to the new token, with Poloniex’s ETHW IOU token trading at $37, or 2.4% of ETH’s value as of the time of writing. Moreover, traders have put on strategies to try to capture any potential value in ETHW, such as buying spot ETH and shorting ETH futures to capture the airdrop while hedging against changes in the price of ETH, though this has helped push the price of futures below the spot price.

For example, the Seed of Life collection on Arbitrum has achieved a total trading volume of $11.79 million, while another collection, Legions Genesis, has brought in over $11 million across the Treasure and PancakeSwap marketplaces. Integration of these popular collections gambling with digital and virtual currencies into the OpenSea ecosystem could see trading volumes on OpenSea report a significant increase. NFT activity on Arbitrum currently pales in comparison to Ethereum, with most of the NFT projects on the platform on smaller marketplaces such as Agora and Stratos.

  • Morgan started forward, his face swimming and rippling as if made of limp plastic, and Jack had time to see there was something clutched in his hand, something hung around his neck, something small and silvery.
  • As mentioned above, Optimism’s dispute resolution process is much simpler and quicker than Arbitrum’s, since it simply feeds disputed transactions through the EVM.
  • Decentralized finance Llama tweeted on its Twitter handle that Aribitrum has approximately $936 million Total Value Locked on 111 different protocols, including GMX, Stargate, Curve, and Uniswap.
  • The protocol uses a ‘health score’ to evaluate the riskiness of loans, with liquidations beginning if a loan’s health score drops below one.
  • Even though disputes will be infrequent, rollups must be designed such that a dispute could arise at any time.

This process, depicted by the diagram below, blunts the force of any would-be spamming attack. Recall that Optimistic Rollups take an “innocent until proven guilty” approach to transaction validity. Optimistic Rollups process transactions and feed the result back to Ethereum for final inclusion in the base chain. A dispute period ensures that anyone monitoring the state of the rollup can submit a challenge if the rollup sequencer has processed transactions invalidly.

The difference between Arbitrum and Optimism is how the dispute resolution process works—including how much it costs and how long it takes. As mentioned above, Optimism’s dispute resolution process is much simpler and quicker than Arbitrum’s, since it simply feeds disputed transactions through the EVM. This speed is to Optimism’s advantage here, since disputes can be resolved quickly and will not prevent future progress of the rollup chain. It’s unclear how much of a practical ufx review » forex marketz constraint the gas limit on Optimism will pose for applications. But another, perhaps more important implication of the difference in dispute resolution design is that Arbitrum can save gas by checkpointing onchain (updating the “state root”) less frequently. More specifically, Arbitrum can assign a large amount of offchain computation to one update, since that state root update could theoretically include single-step fraud proofs of all of the transactions contained therein.

Morgan started forward, his face swimming and rippling as if made of limp plastic, and Jack had time to see there was something clutched in his hand, something hung around his neck, something small and silvery. A new European Union data protection law, the General Data Protection Regulation , went into effect on May 25, 2018. We’ve updated our Privacy Policy and Privacy Notice to give you a clear explanation on exactly why, and how, GSR collects, uses, stores and secures your information. “DA” stands for “disputable assertion,” which is the technical term for a processed transaction that is subject to potential challenge. Recently, there was a new chain launch on Arbitrum using its AnyTrust Technology, it was dubbed ‘Arbitrum Nova’.

They define some key ML terms, tease out some of the nuances of ML training and models, chat zkML and other privacy environments where ML can be trained, and look at why the security around ML will be important as these models become increasingly used in production. Ed and Steven tell Arbitrum’s story, from its beginnings as a chain-agnostic university project in 2014 to become an Ethereum-based Optimistic L2 Rollup solution based on fraud proofs. They cover Arbitrum’s interactive fraud proofs, how they differ from other solutions like Optimism, and how Arbitrum and the Optimistic Rollup helps Ethereum scale. According to the announcement, the leading NFT marketplace plans to launch the layer-2 solution on the 21st of September. Once the deployment is complete, Arbitrum will join other prominent networks on the OpenSea marketplace, alongside Solana, Ethereum, Polygon, and Klaytn. This latest development will see the number of chains supported by OpenSea reach the dizzy heights of five in total.

Since then UK stocks have been gyrating on fears of an impending recession and concerns over a huge increase in borrowing due to Britain’s new tax cuts and spending plans. The broker also noted speculation of a potential Arbitrum token launch in the near term, which could be used to reward early users. In those days, the Sitha had said, most of the world had been covered in ocean, just as the west still was. Jiriki’s folk had sailed out of the rising sun, across unimaginable distances, to land on the verdant coastline of a world innocent of humanity, a vast island in a great surrounding sea. Some later cataclysm, Jiriki had implied, had men changed the face of the world; the land had risen and the seas had drained away to east and south, leaving new mountains and meadows behind them.

However, OpenSea is not the only NFT marketplace that has seen a downturn, with other marketplaces such as Rarible, SuperRare, LooksRare, and Magic Eden reporting similar declines. Bernstein said it expects a host of trading, gaming and non-fungible-token projects to be released on the blockchain. NFTs are digital assets on a blockchain that represent ownership of virtual or physical items and that can be sold or traded. The Nitro upgrade will ease communication between the Arbitrum and Ethereum protocols. Besides, it is also expected to reduce the transaction cost and increase its transaction throughput. According to Offchain Labs, the Arbitrum, with its Optimistic Rollup technology, can reduce fraud and ensure a proper mechanism is set.

This ‘roll-up’ technology illustrates how a validator can manipulate public information to reconstruct a complete chain history from optimized logs. Arbitrum offers high speed in terms of scalability and it also provides additional privacy features to boot. The idea of its development came into play when the ETH network was experiencing difficulties in providing a good user experience.

With the sanctions, OFAC added Tornado Cash-related addresses to its Specially Designated Nationals And Blocked Persons List , a list on which OFAC publishes the names of sanctioned terrorists, authoritarian regimes, and international criminals. Unless exempted or authorized by OFAC, all persons and businesses within the U.S. are prohibited from doing business with its blacklisted constituents. Notably, the list is typically reserved for individuals and entities, and this is the first instance of a smart contract being sanctioned. In addition, developers successfully completed the penultimate mainnet shadow fork, which was executed with zero missed block proposals in the most successful test to date. Finally and after the month ended, developers successfully completed the Bellatrix upgrade, which gave the Beacon Chain logic to be aware that The Merge is coming.

If the client has used another network, or misplaced cryptocurrencies (e.g. sent LTC to a BTC address), please contact us. It needs to belong to the blockchain, which the customer initially sent the funds through (to a BSC/Polygon/Avalanche/Cronos/Arbitrum compatible wallet). In this episode, Anna and Guillermo chat with David Tse about his career and research spanning from early Networking, Mobile Networking, P2P, all the way up to his work on formalizing Blockchain systems.

While many are attempting to position themselves to profit from the fork, there will certainly be a lot to watch at the very least. Also of note, complying with the sanctions, should U.S.-based validators be legally obligated to do so, is no small feat. For example, a transaction may be sent to a non-sanctioned address, but that address may be a smart contract that kicks off a series of transactions that ultimately ends up at a sanctioned address that is impossible to know in advance. In addition, further complications would be introduced should validators be required to determine whether an asset is a part of blocked property, as it would require validators to check an asset’s history rather than just an address.
