Another 8 blocks of the Monero network rewrite
-
On August 13, Qubic reorganized 6 blocks in the Monero Network.
-
The practice is linked to “Selfish Mining”, an economic manipulation strategy of the network.
Within the framework of the conflict between the Monero Network and the Qubic Mining Pool, the XRM chain suffered a new block reorganization on August 17. In total, 8 blocks of the chain were rewritten.
The transactions included in the affected blocks were temporarily in suspense and were invalidated once the network accepted the longest chain as the legitimate version.
In the following image, you can see how the reorganization of 8 blocks in the Monero Network was developed.
The blocks indicated in red correspond to the chain that was discarded, while the green blocks represent The chain finally accepted by the network.
In the image he appreciates how, after a sequence of “orphaned” blocks (red), the network adopted the longest version of the chain, which ended up prevailing as the valid.
The “orphans” blocks are those that were mined validly, but were outside the main version of the chain by not being recognized as part of their definitive history.
The role of Qubic and the “Selfish Mining”
As Cryptonotics reported days ago, monero ecosystem participants linked this type of reorganizations with Qubic, the pool in charge of Perform the practice known as “Selfish Mining” or selfish mining.
This practice is not to immediately publish the blocks that a miner or pool discovers, keeping them secret while continuing to work on the construction of the chain.
In this way, The selfish miner accumulates advantage over the rest of the participants by being able to invalidate blocks already confirmed by other miners. The objective of Selfish Mining It is to obtain more rewards than they would correspond in a fair and distributed mining scenario.
In the case of Monero, the reorganizations suggest that Qubic would be using egoist mining to concentrate economic benefits and gain greater control over the chain.
The recent reorganization of 8 blocks in Monero represents a challenge for this network focused on privacy, especially as it is the second incidence of this type in a few days.
The first reorganization, of 6 blocks, generated some concern, and the increase to 8 suggests a deepening of this trend.
