Coinbase’s Blockchain Security Team just lately recognized a big shift within the Zcash community’s hash energy distribution. A single mining pool, ViaBTC, was discovered to regulate over 51% of the community’s computational energy, elevating considerations about potential safety vulnerabilities.
In Proof-of-Work (PoW) blockchain networks, miners compete to validate transactions by fixing advanced mathematical issues. However, if a single miner or mining pool beneficial properties over 51% of the community’s hash energy, it will probably introduce dangers similar to executing double-spend assaults or censoring transactions. Such centralization can jeopardize person and alternate funds.
Coinbase, dedicated to making sure safety, decentralization, and compliance with digital asset itemizing requirements, has taken a number of steps in response:
Increased Confirmation Requirement: Coinbase has elevated the Zcash affirmation requirement to 110 blocks. This transfer goals to cut back the chance of double-spending or fraudulent transactions, extending the deposit time from roughly 40 minutes to round 2.5 hours.
Limit-Only Trading Mode: To decrease the influence of potential volatility, Coinbase has transitioned its Zcash buying and selling markets right into a limit-only state.
Engagement with Stakeholders: Coinbase has initiated discussions with the Electric Coin Company, the group behind Zcash, and ViaBTC. The dialogue facilities across the dangers related to mining centralization. Coinbase has provided suggestions for methods that might be applied to cut back the chance of a 51% assault.
Coinbase’s Blockchain Security Team conducts thorough safety assessments earlier than including any blockchain to its alternate. A main criterion is making certain that no single entity has centralized management over the community. The staff additionally constantly screens current blockchain networks for vital modifications which may have an effect on their safety evaluations. For PoW networks, specialised hash energy heuristics are employed to detect notable shifts in mining energy.
Coinbase stays looking forward to a decentralized Zcash mining future. While the present mitigations are believed to be enough in defending customers, the corporate emphasizes its ongoing collaboration with exterior companions to make sure the safety of all members within the cryptoeconomy. Coinbase commits to constantly monitoring the state of affairs and adjusting its threat mitigations as essential to safeguard its prospects.
