Builders suggest an answer towards ‘stealth mining’ to Ethereum Basic group

Earlier at this time, Dexaran offered its resolution to the Ethereum Basic (ETC) group aimed toward stopping future 51% assaults. The presentation got here per week after Cardano’s IOHK launched its checkpointing proposal. Dexaran notably used IOHK’s Crowdcast channel for its competing resolution.

This new proposal is based on the idea that many 51% assaults contain so-called “stealth mining”, the place an attacker, in isolation, would secretly mine an extended fork of the chain. This system was utilized in a latest assault on the ETC, which price OKEx $5.6 million.

The proposal hinges on the premise {that a} well-intended miner is unlikely to advance a sequence that requires a deep reorganization of the community. Usually, “sincere” forks contain a single block or, generally, a handful of blocks. Considered one of Dexaran’s presenters specified:

“What this proposes is that, say, there should not be any reorganization deeper than 100 blocks.”

One of many main purported benefits of this resolution is that it requires little or no coding and could be carried out shortly. One other benefit is that it has been carried out by a number of different tasks. As well as, the Dexaran staff believes that their resolution may very well be a stepping stone to the IOHK’s checkpointing resolution, which requires extra time resulting from its complexity. We requested the staff why, if their resolution is able to stopping 51% assaults on the community, there would nonetheless be a necessity for the IOHK’s resolution? They stated:

“We do consider is that as a result of it is a confirmed resolution and it is a examined resolution and it is actually easy to implement, we do consider it is going to simply merely present the mandatory time to have the ability to implement extra advanced options just like the checkpointing system that was proposed.”

Subsequent week, RSK is predicted to current an replace primarily based on Bitcoin’s merged mining.
