Buterin scoffed at crossing the chain again.

Vitalik Buterin, in an online interview on January 20, again mentioned that there was a serious security problem with the chain of passage. . In the case of multiple strings, retrieving the string can be a major issue if there is a problem with the property.

Earlier, Vitalik Buterin in a widely circulated tweet last week opposed Ethereum and other blockchains using cross-chain solutions for much of the future.

For Vitalik Buterin, connecting chains is not good because they increase the security risk when changing assets. This security industry arises because the legacy attack vector grows over a larger area of ​​the network as it travels across multiple chains and decentralized applications with different patterns of security differences.

cross chain chojideas

An inter-chain bridge is an interconnected device that allows you to transfer tokens and valuables from one chain to another. The two chains may have different procedures, rules, and governance standards, and the bridge provides a way to communicate and integrate them so they can impact instruction safety.

With the development of public channels such as Polkadot, COSMOS, Solana, Avalanche and Fantom, all public channels have addressed the benefits of cut channels and extended connectivity.

WormHole is the first cross-chain bridge to support traverses to Solana, Avalanche network has official AVAX bridge, Polygon has official Polygon bridge, Celo network has Optics bridge, Orbit bridge from klaytn network, bridge official Arbitrum, etc.

Polkadot and COSMOS integrate this work into a collaborative platform that supports chain interconnection.

Buterin thinks the chain's crossings have safety issues.

Vitalik Buterin clarified in his tweet: "Now think what would happen if you moved 100 ETH to the Solana bridge so that 100 Solana-WETH and Ethereum were hit by 51%. ETH deposit In many places, Solana-WETH will resume trading Ethereum side as soon as Solana side accepts Solana-WETH contract is not currently fully supported May your 100 Solana-WETH Now it is worth only 60 ETH A perfect ZK-SNARK along the bridge to have full approval, but still effective for thieves attack."

The distribution of assets across different blockchain security networks means that the chain has more impact as existing capital is involved and used for many purposes. The risk of contracting the virus can be influenced by dominoes. When a person is attacked, the assets do not reside on a blockchain, but spread to other blockchain ecosystems. “The problem is worse when you go through two channels. With 100 chains you have a lot of nested chains, and even 51% against a single chain, you get a transmission that disrupts the economy of the whole ecosystem.

Because the whole cross-linking process is difficult, it involves the impact of multiple chains and multiple contracts, and monitoring security risks requires assessment, security monitoring, and bridge crossing inspection. Reviewing and evaluating specific patterns may not cover all security risks on all links and may require new security policies and solutions.

When ETH was integrated with Ethereum, it relied solely on the security controls of the Ethereum network. However, as ETH moves on-chain by cross-chain, ETH security now relies on Ethereum as well as other interconnected systems to identify the security of goal chains and asset transfers. , packaging and additions.

more security

Vitalik Buterin spoke about the important chain link security issues that security professionals need to do more of, but the risk doesn't stop there. Most modern interconnections facilitate asset transformation, often through a combination of core and external users.

These solutions make doing business cheaper and faster, bypassing the difficult and costly chain analysis process. Popular examples include BitGo's Wrapped Bitcoin (WBTC), Axie Infinity's Ronin Bridge, and Terra's Shuttle Bridge.

However, it also means the change is moving away from unreliable analytics data, making them rely on workers to get across the bridge rather than the safety of security on a blockchain-based network.

In short, the significant risks of interconnected solutions can be summarized in two. First, cross-chain solutions increase the number of arrested vectors for crypto assets, increasing the risk of transmission issues. Second, the asset exchange has been merged by various external organizations that cannot remain silent and skeptical, increasing the risk of these same attacks.

cross chain chojRegions are often affected by climate

Blockchain security expert TitaV said that the crosslinking problem will occur more often in 2021. On the evening of August 10, 2021, the poly network, connection work Connected Links, was suddenly attacked by hackers, resulting a loss of $610 million. As the market value of assets at the time of the crisis, it is not only the biggest hack in the history of DeFi, but also the biggest hack in the history of any cryptocurrency. .

According to statistics from PeckShield, there were a total of 19 DeFi security incidents in the third quarter of 2021, of which login-related processes were hacked six times. , AnySwap, THORChain, etc., the total loss is $32.8 million, which is more than all the other groups, excluding polynetwork events which are very large.
