Satsie published a new zine on silent payments. Introduced under BIP352 by Ruben Somsen and Josie Baker in March 2023, they offer a powerful mechanism for private, non-interactive Bitcoin payments. Unlike traditional methods that rely on one-time use addresses, silent payments enable the creation of static, reusable addresses that maintain user privacy. This is achieved through a Diffie-Hellman-style key exchange between the sender’s transaction input and the receiver’s silent payment address. The resulting shared secret is used to derive a unique Taproot address on-chain. While senders benefit from ease-of-use and privacy, receivers face computational overhead, needing to scan all Taproot inputs in new blocks to detect incoming funds. “The receiver doesn’t know any of the on-chain addresses that senders derive,” the guide notes, highlighting the technical challenge. Still, the tradeoff may be worth it, as wallet developers continue to improve tooling and user experience around this promising protocol.

Telecommunications firms are poised to transform their role from digital infrastructure providers into financial innovators by integrating Bitcoin technology. With over 4.7 billion mobile subscribers today and 5.5 billion expected online by 2030, carriers have a massive opportunity to enhance customer experience and streamline operations. By accepting Bitcoin payments and leveraging smart contracts via their existing tech infrastructure, companies can enable instant service activations, automate billing, and reduce reliance on traditional financial systems. “Imagine launching your carrier app, scanning a QR code, and having your bill paid… without banking middlemen,” writes André França. Emerging use cases include micropayments via the Lightning Network and loyalty tokens, as tested by SK Telecom. However, volatility, regulatory complexity, and customer education remain key hurdles. As global data traffic surges toward 466 exabytes per month by 2029, forward-looking carriers will use Bitcoin to reshape connectivity and commerce alike.

BitVM3 introduces a major leap in optimizing SNARK proof verification on Bitcoin by replacing on-chain computation with an off-chain RSA-based garbled circuit system. Designed by Robin Linus, the protocol builds on BitVM2 but slashes transaction sizes (down to a mere 56 kB assertion and a 200-byte dispute), making on-chain verification over 1,000 times cheaper. The architecture hinges on optimistic computation: the garbler creates a circuit that only reveals a fraud proof if invalid input is detected. “BitVM3 significantly advances Bitcoin’s contracting capabilities,” Linus notes, enabling scalable, trust-minimized rollups and bridges. While requiring potentially massive 5 TB off-chain setups for large SNARK circuits, this one-time cost is justified by its efficiency. With a 250 Mbps upload, sharing the circuit takes under two days. As Bitcoin evolves into a powerful settlement layer, BitVM3 signals a potential direction for secure, verifiable, off-chain computation.

Trump Media and Technology Group (TMTG), operator of Truth Social, has received SEC approval to convert $2.3 billion in capital into a bitcoin treasury, making it one of the larger corporate bitcoin holdings to date. Following a Form S-3 filing on June 6, the SEC declared the registration effective, enabling TMTG to use proceeds from prior securities sales involving 85 million shares to acquire bitcoin. Nearly 50 institutional investors participated, including DRW’s Don Wilson, who contributed $100 million. CEO Devin Nunes described the move as a strategic hedge against “financial discrimination,” and part of a broader expansion into fintech via its Truth.Fi subsidiary. The company also filed for a spot bitcoin ETF—Truth Social Bitcoin ETF—signaling an aggressive pivot toward digital asset integration and raising questions about Federal policy timing. Custody will be handled by Crypto.com and Anchorage Digital. The approval marks a high-profile, albeit politically charged endorsement of Bitcoin as an institutional reserve asset.
