Coinbase’s Blockchain Safety Group just lately recognized a major shift within the Zcash community’s hash energy distribution. A single mining pool, ViaBTC, was discovered to manage over 51% of the community’s computational energy, elevating issues about potential safety vulnerabilities.
In Proof-of-Work (PoW) blockchain networks, miners compete to validate transactions by fixing advanced mathematical issues. Nevertheless, if a single miner or mining pool good points over 51% of the community’s hash energy, it might introduce dangers resembling executing double-spend assaults or censoring transactions.
