In the ever-evolving world of cryptocurrency, the Zcash network has recently found itself facing a significant challenge that has raised alarm bells within the digital currency community. As of September 19, 2023, the Viabtc mining pool has gained control of a staggering 53.69% of the total Zcash network hashrate, casting a shadow over the network’s decentralization and security.

Viabtc’s Dominance and Its Implications

With a hashrate of 4.2 giga solutions per second (GSol/s) out of a total hashrate of 7.84 GSol/s, Viabtc’s grip on more than half of the Zcash network’s computational power poses a serious threat. This development has sent shockwaves through the cryptocurrency community, sparking discussions and responses from key industry players.

Coinbase’s Swift Response

One of the major cryptocurrency exchanges, Coinbase, wasted no time in addressing the critical issue. In their “Security PSA,” they shed light on the risks associated with the concentrated distribution of mining pools within the Zcash network. To protect their customers’ assets, Coinbase implemented immediate measures, including moving Zcash markets to a “limits-only state” and increasing the confirmation requirement to 110 blocks. This move, while aimed at reducing the risk of duplicate charges or fraudulent transactions, did come at the expense of deposit time, which increased from about 40 minutes to approximately 2.5 hours.

Electric Coin Co.’s Proposed Solution: Trailing Finality Layer (TFL)

Electric Coin Co. (ECC), the entity overseeing the Zcash project’s code base, recognized the gravity of the situation and engaged with Coinbase, Viabtc, the Zcash security manager, and Zcash Community Grants. ECC emphasized the decentralized nature of Zcash, noting the absence of a “main developer,” “issuer,” or monitoring organization. They identified the core issue as the “lack of purpose.”

ECC’s proposed solution to address this lack of purpose is the Trailing Finality Layer (TFL). This innovative approach seeks to introduce finality into the Zcash network, thereby mitigating the risks associated with a dominant mining pool. The TFL proposal represents a significant step toward enhancing the security and decentralization of Zcash. Furthermore, ECC expressed its commitment to exploring a transition to a proof-of-stake (PoS) system, ranking it among their “top four priorities.” By adopting a hybrid PoW-PoS approach, the Zcash network could expedite its journey toward greater security and decentralization. ECC’s next step involves building a prototype TFL to evaluate its performance and feasibility.

Community Involvement: A Vital Component

In addressing the issues of finality and potential changes in consensus mechanisms, it is imperative to underscore the significance of community involvement. Zcash, like many cryptocurrencies, is rooted in decentralized and open-source principles. As ECC explores solutions and industry players respond, the active participation of community members and stakeholders in discussions about the future of Zcash becomes critical. Decisions related to network upgrades, consensus changes, and the implementation of solutions such as TFL or transitioning to PoS must be made collectively, reflecting the diverse perspectives and interests within the Zcash ecosystem.

Challenges and Opportunities Ahead

The challenge posed by Viabtc’s dominance not only underscores immediate concerns but also presents opportunities for innovation and adaptation within the cryptocurrency landscape. Zcash’s journey toward resolving its lack of finality and enhancing its security showcases the resilience and creativity of the cryptocurrency community.

As Electric Coin Co. continues its work on the TFL prototype and explores the possibilities of PoS, there will undoubtedly be technical hurdles to overcome. Testing and refining these solutions will require collaborative efforts and rigorous analysis. Furthermore, the broader cryptocurrency industry can draw valuable lessons from Zcash’s experiences. The need for robust, decentralized networks is a common thread in all blockchain projects. The solutions developed for Zcash can serve as inspiration for similar innovations in other cryptocurrencies, further advancing the entire industry.

In Conclusion

Viabtc’s dominance in the Zcash network has brought to light a significant challenge in the cryptocurrency world: the lack of purpose. Coinbase’s proactive response and Electric Coin Co.’s proposed solution, the Trailing Finality Layer (TFL), demonstrate the industry’s commitment to addressing this challenge. As discussions continue regarding the Zcash network hashrate and mining pool distribution, it is clear that the cryptocurrency community is acutely aware of the importance of preserving decentralization and security. In the coming months, we can expect further developments and innovations aimed at ensuring the strength and longevity of the Zcash network in the face of such challenges.
