Vitalik Buterin Shares His Views on Cross-chain Bridges

Vitalik Buterin Shares His Views on Cross-chain Bridges
  • The “honest” blocks, according to Buterin, will keep the state consistent.
  • Buterin argued that a cross-chain environment was undesirable.

Ethereum co-founder Vitalik Buterin tweeted a link to a Reddit article today that discusses his optimism in a multi-chain future but expresses doubts about cross-chain ecosystems. Because of the “fundamental security restrictions of bridges,” Buterin argued that a cross-chain environment was undesirable.

Buterin further said that he disagrees that all security procedures fail if and when a blockchain experiences a 51% assault. By controlling more than 50% of the network’s mining hash rate or processing power, the goal of a 51 percent attack is to influence the integrity of the transactions being logged in a blockchain. The same concept, according to Buterin, applies to any Layer 2 created on top of the Ethereum mainchain. 

Buterin wrote: 

“If Ethereum gets 51% attacked and reverts, Arbitrum, and Optimism revert too, and so “cross-rollup” applications that hold state on Arbitrum and Optimism are guaranteed to remain consistent even if Ethereum gets 51% attacked. And if Ethereum does not get 51% attacked, there’s no way to 51% attack Arbitrum and Optimism separately.”

Protocol Regulations

The attackers, according to Buterin, would be unable to propose a block that would take away someone’s ETH in the event of a 51 percent assault since doing so would break the consensus rules and be rejected by the network.

To put it another way: Even while 99 percent of hash power was oriented toward stealing from another wallet’s Ethereum, the remaining 1 percent of nodes would follow that chain since it obeys protocol regulations. As a result, the “honest” blocks, according to Buterin, will keep the state consistent.

Ethereum NFT Limitations Allows Alternative Blockchains to Thrive

SMB is a collection of 5,000 randomly produced 24×24 pixel monkeys. CryptoPunks NFT avatar sold for $500 million in October. Non-fungible tokens (NFTs) have never been more popular. OpenSea , Axie, and Rarible are fantastic NFT markets to use while offering an NFT marketplace development service beneficial for organizations entering the Blockchain Ocean. Decentralized finance, smart contracts, and NFTs are built on Ethereum . Despite its popularity, the platform is under stiff competition. While Ethereum and Solana have supporters, Ethereum is the most popular because it has the most transparent Dapp ecosystem. These opponents have some notable contrasts that cannot be overlooked. Moreover, cryptocurrency, applications, and worldwide payments all reside on Ethereum’s blockchain. Ether has a restricted transaction rate. It is also quite congested, forcing users to either pay a hefty charge or wait in line, allowing alternative blockchains to thrive. Solana Blockchain handles 30...

Can Bitcoin (BTC) and Ethereum (ETH) Rebounce Again?

Image
The BTC price is already at a three-month low. The daily chart of Ethereum price levels showed a falling wedge shape. The Bitcoin price rebounded on Sunday, January 9, ending a six-day sideways trend. At press time, Bitcoin was trading at $41,898, with a $792 billion market value. On-chain data and RSI levels have been suggesting a trend reversal. The US Inflation Data due on Wednesday will be a significant factor to monitor. The CPI report will eventually determine whether the Fed will increase quantitative tightening (QT), affecting market liquidity and pushing up bitcoin prices. The BTC price is already at a three-month low, and any further decline might be catastrophic. The Bitcoin RSI has been at its lowest levels, perhaps indicating oversold conditions. The Bitcoin RSI has dropped to its lowest level in two years. This level was last observed in March 2020 and May 2021. However, bitcoin has started to bounce back and has gained 0.82 over the last 24 hours. BTC/USDT: Sou...

Arbitrum Network Experienced Second Outage in Less Than 5 Months

Image
Team members reported the main Sequencer node hardware failure. 284 transactions were caught by the Sequencer. Arbitrum, Ethereum’s most popular Layer 2 solution today, has over $2.5 billion in total value locked up. While numerous Ethereum DeFi protocols, like Balancer and Uniswap, have already joined the mainnet since its August 2021 debut, more are anticipated to follow. Yesterday, due to a Sequencer failure, transactions could not be completed for seven hours. The Ethereum layer-two network, Arbitrum, had its second outage in less than five months due to a hardware malfunction. The Arbitrum One chain’s last block before the outage struck, according to Arbiscan and Offchain Labs data, was 4509808 and processed at 10:29:22 UTC on January 9. The Arbitrum team said: “The Sequencer is back online. Thank you very much for patiently bearing with us as we resolved the issue. More details about what occurred to follow.” Undergoing Testing and Still in Beta Phase In a subseque...
