Inside Zcash's new node that targets Visa-scale privacy at 50,000 transactions per second
COINDESK ·
On May 29, Shielded Labs researcher Taylor Hornby found that the proof circuit for Orchard, the newest shielded pool, contained a soundness bug that let an attacker mint counterfeit ZEC with no onchain trace. The flaw had been live since Orchard activated in May 2022. Developers disabled Orchard through an emergency response completed June 2, then restored it with a corrected circuit via the NU6.2 hard fork at block 3,364,600 on June 3. The patch could not account for the four years the hole was open. A zero-knowledge proof reveals nothing beyond the fact that it verified, so the chain holds no record of what any Orchard transaction moved, and nobody can prove counterfeit ZEC was never created. Ironwood is built to settle that. A so-called ‘turnstile’ at the pool's boundary caps what can leave and what can enter, leveraging the fact that ZEC amounts crossing into or out of shielded pools are public even when the transactions inside are not. Sealing Orchard to new deposits leaves the turnstile as the only exit, and any fake coins inside are stuck there. In simple terms, honest balances can migrate out over time, while counterfeit coins may be prevented from fully exiting and entering into circulated supply. This setting traps any attempted excess supply at the boundary, restoring reliability of the token’s supply.
AI 시장 분석
Zcash has unveiled a new node technology capable of processing 50,000 transactions per second, aiming for Visa-level scalability. This initiative seeks to address the persistent issues of transaction speed and privacy in existing blockchains. Investors should closely monitor whether this technical breakthrough leads to actual network adoption and an increase in ZEC price.
상승 영향
- Cryptocurrency — Achieving 50,000 TPS addresses the scalability challenge inherent to blockchain mass adoption, enhancing ZEC's asset value and enabling entry into the large-scale payment market.
DYAX 전담 분석
The announcement marks a pivotal shift for Zcash, potentially positioning it as a competitor to traditional payment networks like Visa. By overcoming throughput limitations, Zcash aims to make privacy-preserving transactions viable for mainstream use cases.
However, the success of this technology depends on actual deployment and market integration. Future price performance will likely be driven by network growth and the ability to maintain decentralization while achieving such high performance.
