Vitalik Buterin, co-founder of Ethereum and a major pillar of the crypto community, tweeted earlier that Proof of Stake (POS), algorithms should have safeguards against 51% attack and that any attack should be dealt with mid-level nuisance rather then a disaster.I think PoS should be designed so that 51% attacks are a recoverable medium-sized nuisance and not a stop-this-at-all-costs nuclear disaster. I have some ideas on how to push the Eth2 design in this direction.
Ethereum 2.0
He also stated that he has design ideas for the next version of Ethereum (also known by Ethereum 2.0), which will include such safeguards. This statement is significant in light of the ETH2.0 stability arguments and debate about the possible impact of an attack on Ethereum on DeFi products that have hundreds of millions of dollar locked in them. This shows that the Ethereum team is fully aware of potential problems and is working hard to ensure a smooth transition to the next version.
The algorithm relies on interested users locking their coins (or stakes) to manage and operate the network. Stakers are paid staking rewards in exchange for their contributions to the running of the network. This is mostly in the form of fees for transactions on the network. Because stakers can lose their coins or stake if they act against the network’s health and interests, it is called Proof of Stake. It is more efficient and resource-friendly than the competing Proof of Work (POW), which requires a lot of expensive resources to run the network.
The 51% Attack
The fifty-one percent attack is based on miners and stakers controlling the majority of the hashpower on the network and acting maliciously to harm it. It doesn’t necessarily have to be one entity, since it is impossible for any one entity to have such processing powers. But different entities can come together and conspire against the network. 51% attacks, if successful, can cause network disruption. Malicious actors can reverse transactions even after they are confirmed, double-spend tokens, or disrupt the network in any other way.
Proof of Stake
How will Ethereum prevent Proof of Stake (POS 51% Attack)? Details are still unclear as Ethereum 2.0 is still in development. The Dash Cryptocurrency, the most secure network, may be a clue to solving this problem. Dash is not a Proof of Stake (POS), but it does rely on Masternodes. They are able to randomly select a quorum from 400 Masternodes and then generate consensus on the most recent valid block. This prevents any malicious actor from reorganizing the chain. It relies on a mechanism called “Chainlocks” to protect against 51% attacks. Ethereum could use a similar mechanism to stop 51% attacks. However, it remains to be determined what exact mechanism will be used by the Ethereum team.
The World’s Computer
The next iteration, Ethereum 2.0, is expected to officially launch sometime in 2022. The Ethereum 2.0 blockchain will be a separate one, and will be developed in phases. It will feature improvements in speed, execution security, and scalability. It will also allow for a transition from Proof of Work to Proof of Stake (POS).
Optimistic Virtual Machine
A new startup focusing on the frontlines of a number of the cryptoeconomy’s most promising technology has released the alpha version of an instrument that may bring layer-two scaling to base layer Ethereum smart contracts. On February 11th, Optimism, which rebranded from the Plasma Group research outfit right into a Public Benefit Corporation last month, unveiled its Optimistic Virtual Machine (OVM) alpha.
Optimism’s work targets so-called “Optimistic Rollup” tech, that may actualize highly scalable sidechains that may considerably extend the capabilities of Ethereum’s main chain. Accordingly, working such as a “containerized L2-compatible EVM within the EVM,
It is New
The arrival of the OVM means the Ethereum ecosystem is now able to leverage this powerful tool to optimize the smart contract platform’s decentralized services further. Because the Optimism team explained within their reveal post, the OVM is young but poised to become increasingly useful as time passes:
“We put Uniswap on L2, but you can find so many cool smart contracts on Ethereum – we have to support all of them! Upgrading smart contracts to Optimistic Rollup / L2 ought to be as simple as a recompilation & redeployment.”
Like Uniswap, then, the others of Ethereum’s decentralized finance sector is now able to utilize L2 capabilities through the OVM. So when the DeFi arena and the OVM continue steadily to mature, Ethereum itself will undoubtedly be evolving into “Ethereum 2.0,” which can make use of things such as proof-of-stake (PoS) consensus and scaling with a sharding system. The Optimism team confirmed they created the OVM to be readily embraceable by Ethereum 2.0.
Rollups Play
The researcher John Adler helped to spearhead the theoretical work that resulted in the recent advent of Optimistic Rollups in the Ethereum community. Now, Adler is putting theory into practice, having launched Fuel Labs with Nick Dodson last fall to be able to create Fuel, a permissionless Optimistic Rollup sidechain system.
In January, Which means things are still in early stages for the project, Indeed, perhaps one of the most interesting aspects of Fuel is merely how secure it really is while also being incredibly ideal for powering huge amounts of payments. “Much like any properly-design optimistic rollup, the only path to attack it really is for miners to conduct a week-long 51% attack on the primary chain – highly visible, easily attributable, and impossible used for a chain as important and secure as Ethereum,” Fuel’s creators have previously explained.
Near Future
Null Transition, was early January 2020. That window has come and gone now, needless to say. Sufficient reason for more last-minute efforts left to complete up, Ethereum’s developers are actually eyeing July 2020 as a fresh likely Ethereum 2.0 launch point in accordance with answers posted in a Reddit “Ask Me Anything” thread conducted with ETH2 researchers the other day.
“I’ve 95% confidence we shall launch in 2020, Whenever Serenity eventually ends up launching, and for the present time the platform’s builders turn to be well on the right track to kick that evolution off in a matter of months.
