Qubic’s actions have introduced the integrity of the Monero community below query, with one commentator figuring out the frequency of “orphaned” (deserted) blocks at practically 30% over a 24-hour interval.
Qubic beforehand claimed to manage 51% of the community, although later evaluation concluded that its actual hashrate was almost definitely between 28% and 35%. Then got here a wave of reorgs, saved under the vital 10 block threshold used to verify transactions.
The newest reorg, with a depth of 18 blocks, might lead to double-spending of tokens affecting any customers who’re nonetheless utilizing 10-block affirmation instances.
Response to Qubic’s 18 block reorg on Monero
Some see the most recent assault as Qubic desperately making an attempt to remain related as its token worth bleeds out, whereas others have criticized the shortage of a definitive response from the Monero group as “amateur hour.”
Qubic’s hash seize marketing campaign on Monero hinges on promoting mined XMR and paying its miners in QUBIC, at the next charge than common mining.
The tactic started to lift eyebrows in late July, prompting a surge within the worth of QUBIC.
Nonetheless, since peaking in mid-August, Qubic’s token has misplaced over a 3rd of its worth, in keeping with knowledge from CoinMarketCap. In the identical interval, Monero’s XMR is up roughly 25%.
Clearly undeterred, Qubic founder Sergey Ivancheglo additional stoked the rivalry: “Monero will stay because Qubic wanted it to stay.”
Group response has centered on varied proposed technical options, however the delay of their implementation has led to frustrations.
One account, with the X deal with “Exitnode,” summed up the frustration.
As an alternative of addressing the Qubic menace, they are saying that builders are “working on a future upgrade that isn’t live.” Stating that one warning got here a yr in the past, they ask, ”Why have so few proven urgency to this case?”
One other account, Monero Analysis Lab (Unofficial), states it’s “highly likely that temporary rolling DNS checkpoints will be deployed very soon.” This emergency protection measure would act as a stop-gap whereas long run options are launched.
The method includes “checkpointed” blocks that are mined by the Monero Core Group’s nodes. The GitHub difficulty states, “DNS checkpoints… could prevent deep blockchain re-organizations, but Monero’s blockchain consensus protocol would temporarily be less decentralized.”
