Great being at #WDMS2026 and sharing my perspective on why Zcash’s time is now. Zcash today looks a lot like Bitcoin in 2013, an early-stage network with a differentiated value proposition, growing momentum and significant room to scale. Privacy is becoming increasingly important, while the Zcash ecosystem continues to evolve across technology, adoption and market access. That’s why we’re anchored in Zcash at Fortitude, investing in the infrastructure and capacity to support where we believe the network is headed. $ZEC $HSCS See important additional information here: fortitudemining.com/disclaim…

At #WDMS2026, Fortitude CFO @Ellingson_Erik made the bullish case for Zcash, highlighting the convergence of privacy, quantum resistance, adoption and expanding market access. Zcash today looks a lot like Bitcoin in 2013. $ZEC $HSCS See important additional information here: fortitudemining.com/disclaim…

A major milestone for Zcash. Today marks the first day of trading for The Zcash ETF ($ZCSH). Built by Grayscale, $ZCSH is the first ETF in the world to offer spot exposure to $ZEC, the native token of Zcash. We believe privacy will become an increasingly important part of the future of digital money, and Zcash is well-positioned for the growing need for private, digital cash. Fortitude is building for this opportunity by investing in the infrastructure needed to support Zcash’s long-term growth. See important additional information here: fortitudemining.com/disclaim…

A Z15 Pro mining Zcash is currently yielding roughly 3x the industry-average AI/HPC benchmark per MWh. Fortitude began mining $ZEC, the native token of the Zcash network, in 2019. This is our venture mining playbook in action. Read more: theenergymag.com/news/2026-0…. See important additional information here: fortitudemining.com/disclaim…

Fortitude CFO @Ellingson_Erik is speaking at #WDMS2026 on the panel “Venture Mining: The Zcash Opportunity.” Erik will discuss the opportunity around Zcash, why now is a pivotal moment for privacy across the digital ecosystem, and the growing case for $ZEC.

Strong Q2 for @FortitudeCrypto mining $ZEC at scale and marching ahead toward public markets
 
$HSCS 



.@FortitudeCrypto delivered a strong cash-flowing quarter in Q2, generating $20.9 million in revenue driven by continued ZEC hashprice and hashrate performance across our fleet. This translated into robust operating cash flow indicated by adjusted EBITDA of $8.5 million, reinforcing the strength of our ZEC-focused mining strategy as we continue to prepare to close our proposed business combination with HeartSciences. $ZEC $HSCS

This was a strong quarter for @FortitudeCrypto and a clear demonstration of the momentum building in our vertically-integrated strategy. We mined approximately 33,646 ZEC at an average operating hash rate of 4.0 GSol/s. As we work to advance toward the public markets via our proposed business combination with HeartSciences, we remain thrilled about the opportunity ahead and our ability to execute on it. The momentum keeps building. $ZEC $HSCS

Fortitude Provides Second Quarter 2026 Financial and Operating Highlights: • $20.9M revenue and $8.5M Adjusted EBITDA • Approximately 33,646 ZEC mined at 4.0 GSol/s, with recent site and fleet expansions bringing owned-and-operated power to 60+ MW • Purchased ~$1.0M of HeartSciences (Nasdaq: HSCS) common stock in a private placement; proposed business combination expected to close in H2 2026 Read the full release which includes a reconciliation of Adjusted EBITDA to the most directly comparable GAAP number as well as additional important information: businesswire.com/news/home/2…. $ZEC $HSCS

Love the momentum. This is the largest inter-pool movement in Zcash history. As of today (Aug 6), the new pool holds over 1.33 million zcash:native (~7.9% of circulating supply), with roughly one-third of the former Orchard balance having already crossed the turnstile. As a reminder, Ironwood (NU6.3) activated on schedule at block 3,428,143 on July 28, 2026. It introduced a fresh shielded pool using the corrected Orchard circuit, formal verification (including machine-checked proofs), independent audits, and quantum-recoverable notes (ZIP 2005). This followed discovery of a soundness vulnerability in Orchard’s zero-knowledge circuit (Halo 2) by Shielded Labs researcher Taylor Hornby in late May 2026. The prior Orchard pool was restricted to withdrawals only. Funds can exit only through the protocol's turnstile, which enforces that no more ZEC can leave than was verifiably deposited—giving every node operator for an independent, trustless check on circulating supply integrity. Appreciate all the work from @ShieldedLabs, @ZcashFoundation, @Zodl_co, @TachyonZcash, and @ValarGroup. Our conviction in the Zcash network is only getting stronger! More to come, and proud of the team and ecosystem thus far. $HSCS zcash:native Source: shieldedlabs.net/ironwood/. See important additional information here: fortitudemining.com/disclaim…
