Zcash is a privacy-focused cryptocurrency that uses trustless zero-knowledge proofs to enable fully encrypted transactions while maintaining blockchain transparency and security. It was the first cryptocurrency to implement zero-knowledge encryption for private peer-to-peer payments, addressing the fundamental privacy gap in traditional cryptocurrencies that expose transaction details publicly.   With a fixed supply of 21 million ZEC and a halving schedule similar to Bitcoin, Zcash allows users to prove transactions are valid without revealing sensitive information like wallet balances, transaction amounts, or participant identities, making it suitable for everyday payments, long-term savings, and cross-border money transfers where financial confidentiality matters.  The protocol operates on its own blockchain currently using Proof-of-Work consensus, though it's evolving toward Proof-of-Stake through the planned "Crosslink" upgrade to enhance security, scalability, and energy efficiency. Zcash employs trustless zero-knowledge proofs (Halo) within its Orchard shielded pool to verify transactions without revealing sender, receiver, or amount information.   Users can choose between transparent public transactions and shielded private transactions through Unified Addresses, which work with both types. The network is faster and cheaper than Bitcoin, with new blocks mined every 75 seconds and transaction fees typically just a fraction of a cent. Privacy adoption has surged in 2025, with over 30% of total ZEC supply now held in fully shielded pools.  Zcash was created by a group of scientists in 2013 who initially proposed Zerocoin as a privacy extension to Bitcoin before building a standalone protocol. The ecosystem operates with a self-funded development model where block rewards support independent teams through the Zcash Community Grants Committee and a new Coinholder-Controlled Fund.

Zcash is trending amid community discussion around its potential as 'the new Bitcoin' and increased institutional interest, particularly following investments from figures like the Winklevoss twins. Conversations highlight ZEC's privacy features and limited supply, with some suggesting a significant shift from Bitcoin to Zcash. Bullish sentiment is tempered by concerns about volatility and potential corrections.

Litecoin is a peer-to-peer cryptocurrency created by Charlie Lee. It was created based on the Bitcoin protocol but differs in terms of the hashing algorithm used. Litecoin uses the memory intensive Scrypt proof of work mining algorithm. Scrypt allows consumer-grade hardware such as GPU to mine those coins.  Why Litecoin? Litecoin is a cryptocurrency that has evolved from Bitcoin after its own popularity in the industry, this alternative, or ‘altcoin’ has emerged to allow investors to diversify their digital currency package, according to Investopedia. Litecoin is one of the most prominent altcoins and was created by former Google employee and Director of Engineering at Coinbase, Charlie Lee. Litecoin was the first to alter Bitcoin and the most significant difference is that it takes 2.5 minutes for Litecoin to generate a block, or transaction, in comparison to Bitcoin's 10 minutes.  ‘While this matters little to traders, miners who use hardware to run Bitcoin's network cannot switch over to Litecoin. This keeps bigger mining conglomerates away from Litecoin because they cannot easily optimize their profits by swapping to another coin, contributing to a more decentralized experience. Litecoin also has bigger blocks, and more coins in circulation, making it more affordable and swift when transacting,’ Investopedia explained.  As explained above, Litecoin can transact a lot faster than Bitcoin, but there are also a number of other characteristics that investors need to know before trading. Litecoin can handle higher volumes of transactions because of the capability of transacting faster and if Bitcoin attempted to transact on the scale of its altcoin, a code update would be needed. However, Litecoin’s blocks would be larger, but with more ‘orphaned blocks'. The faster block time of litecoin reduces the risk of double spending attacks - this is theoretical in the case of both networks having the same hashing power.  Litecoin Technical Details: The transaction confirmation time taken for Litecoin is about 2.5 minutes on average (as compared to Bitcoin's 10 minutes). The Litecoin network is scheduled to cap at 84 million currency units.   Litecoin has inspired many other popular alternative currencies (eg. Dogecoin) because of its Scrypt hashing algorithm in order to prevent ASIC miners from mining those coins. However it is said that by the end of this year, Scrypt ASIC will enter the mass market.

NVNO's Shares Decline on Unfavorable FDA Review Outcome for VenoValve

enVVeno Medical shares plunge after the FDA rejects its VenoValve PMA, citing insufficient trial data and safety concerns tied to the surgical procedure.

Medical device company enVVeno Medical Corporation (NVNO) on Wednesday announced that the U.S. Food &amp; Drug Administration (FDA) has refused to approve its application for its lead product, VenoValve, a surgical replacement venous valve for treating severe deep chronic venous insufficiency (CVI).Following the announcement, NVNO shares plunged 71% by Wednesday afternoon, at the time of writing.Severe deep chronic venous insufficiency (CVI) is a long-term condition where the veins in the legs have difficulty returning blood to the heart, leading to blood pooling and various symptoms like swelling, aching, and skin changes. This occurs primarily due to damaged or weakened valves within the deep leg veins.On Stocktwits, retail sentiment around <a href="https://stocktwits.com/symbol/NVNO">NVNO</a> rose from ‘neutral’ to ‘extremely bullish’ territory over the past 24 hours, while retail chatter rose from ‘low’ to ‘extremely high’ levels.<figure class="image"><img style="aspect-ratio:563/61;" src="https://news.stocktwits-cdn.com/Screenshot_2025_08_20_at_12_41_02_PM_png_bca2208bb7.webp" alt="NVNO's Sentiment Meter and Message Volume as of 12:40 p.m. ET on Aug. 20, 2025 | Source: Stocktwits" width="563" height="61"><figcaption>NVNO's Sentiment Meter and Message Volume as of 12:40 p.m. ET on Aug. 20, 2025 | Source: Stocktwits</figcaption></figure>A Stocktwits user expressed optimism for the company renegotiating with the FDA.<stembedurl>https://stocktwits.com/Flying_Trader2/message/625960642</stembedurl>Another user said that they see no value in the company with the VenoValve rejection.<stembedurl>https://stocktwits.com/kmx_swing/message/625941525</stembedurl>The FDA <a target="_blank" rel="noopener noreferrer nofollow" href="https://envveno.com/envveno-receives-not-approvable-letter-from-the-fda-for-the-venovalve/">said</a> in a letter that it completed its review of the company’s application for VenoValve but has decided that it is unable to approve it in its current form. The agency said that data generated by the company for the application was not sufficient on its own to determine the favorability of the benefit-risk profile for VenoValve.The FDA also raised concerns about bias and the possibility that clinical improvement occurred as a result of the patients being enrolled in a study. The agency further raised safety concerns, which were attributed to the VenoValve open surgical procedure, and which required re-hospitalizations.CEO Robert Berman said that the company is disappointed by the FDA’s decision and highlighted that a high percentage of patients in a study showed significant clinical improvement after receiving VenoValve. Berman added that the company will continue to work with the FDA on new criteria to demonstrate the safety and effectiveness of the device.The firm’s next steps may include a meeting with the FDA to discuss requirements for a potential resubmission of the VenoValve or appeal of the decision, along with appropriate next steps.NVNO stock is down by 59% this year and by about 77% over the past 12 months.&nbsp;Read also: <a href="https://stocktwits.com/news-articles/markets/equity/elon-musk-says-tesla-model-yl-might-not-ever-come-to-us-markets/chsitLlRdhq">Elon Musk Said Tesla’s Model Y L Might Not Ever Come To US Markets – Here’s Why</a>For updates and corrections, email newsroom[at]stocktwits[dot]com.
