The first hard fork for Ethereum 2.0: What is it, what will it do?


Vitalik Buterin, developed under Ethereum 2.0 Beacon chain Suggest a hard fork to. The new Hard Fork is expected to make the Series a beacon more user-friendly for mobile devices and fix some security issues on the network.

Beacon Chain, which is part of the Ethereum roadmap, launched at the end of last year. At the time of Beacon Chain, also known as Phase 0, there were some minor issues that were delayed to be fixed.

It aims to solve three major problems

Highlight the invoice, Portable devices It was on the verge of. The expected improvement in the sync panel will enable mobile devices and browsers to monitor the blockchain with less force.

The minimum requirement for daily tracking is around 20 KB; The minimum requirement for block validation is around 500 bytes

Vitalik Buterin: “Light Beacon Chain (and Ethereum 2.0) customers could be suitable for mobile devices and browsers.”

Among the plans is to reduce the penalty for a regular job auditor; Toughening the penalty for the violating employee. Its connection is due to various problems ara ara With Checker hangs and stays offline for 1 hour Non-stop for an hour Penalty for an offline auditor Think will not happen. To the choppy checker Ten times less We will be punished.

Vitalik Buterin: “The goal here is to reduce the penalties imposed on nodes that have communication problems (beyond their control), and to cut off the actual penalty for nodes that are actually working incorrectly.

The other thing that has emerged with HF1 is the presence of potential weaknesses in the branching mechanism. Current fork system, 34 percent attack And the Balance attack It may cause such attacks. To avoid these problems, it is recommended to re-place the validators in the network under the necessary conditions and to make the counting of votes during the crossroads safer.

Balance attack: An attacker who controls 2% of auditors captures the “right moment” and provides some testimonials. Attacker, 49% of Checkers ahead of Block A; Makes the other 49 percent believe the B block is advanced. If the attacker can really match the timing, he can deceive both sides.

He wants to prevent future problems

It aims to eliminate some of the problems with the first version of Beacon Chain in this way. It is believed that the solutions to be presented especially in relation to the branching mechanism will be useful in the future.

Ethereum developers over time ecosystem under update 2.0 Retail They aim to introduce methods like. While these stages have not yet been reached, Vitalik Buterin believes it would be beneficial to try this mechanism early.

When will this be done, what will its name be?

It is not known when all of these proposed changes will take effect. Initial phase HF1 It is expected that the name of the proposal submitted will change along with its name. Some of the names suggested so far are as follows:

  • Vitalik Buterin’in önerileri: Azshara / Ashenvale / Arathi, Badlands / Blasted Lands, Desolace, Elwynn Forest, Feralas / Felwood,
  • Edson Ayalon’s suggestions: Sirius, Altair, Arcturus, Antares,
  • Matt Garnett Recommendations: Amsterdam, Berkeley, Cairo
