Coinbase-Backed RISC Zero Launches ’Boundless’ Incentivized Testnet on Base Network

RISC Zero's decentralized zero-knowledge compute marketplace, Boundless, has officially launched its incentivized testnet, referred to as 'Mainnet Beta,' on Base, Coinbase's ethereum layer-2 network. This development marks a significant milestone for developers looking to build and test applications in a simulated live environment. The project has garnered early support from prominent entities such as the Ethereum Foundation, Wormhole, and EigenLayer, highlighting its potential to revolutionize the zero-knowledge proof marketplace. Boundless aims to provide a decentralized platform where developers can leverage zero-knowledge proofs to enhance privacy and scalability in blockchain applications. The launch on Base, a layer-2 solution backed by Coinbase, further solidifies the project's credibility and accessibility within the crypto ecosystem. As of July 2025, this initiative is poised to attract significant attention from developers and investors alike, given the growing demand for scalable and privacy-focused blockchain solutions. The incentivized testnet offers participants the opportunity to engage with the platform while earning rewards, fostering early adoption and community involvement. With its robust backing and innovative approach, Boundless is set to play a pivotal role in the evolution of decentralized compute markets, aligning with the broader trends of blockchain interoperability and zero-knowledge proof adoption.

Risc Zero’s 'Boundless' Incentivized Testnet Launches on Base

RISC Zero's decentralized zero-knowledge compute marketplace, Boundless, has gone live with its incentivized testnet—dubbed 'Mainnet Beta'—on Base, Coinbase's Ethereum layer-2 network. The platform allows developers to build and test applications in a simulated live environment, with early backing from the Ethereum Foundation, Wormhole, and EigenLayer.

Boundless operates as a decentralized marketplace for zero-knowledge proofs, connecting developers of rollups, bridges, and privacy-focused applications with a distributed network of independent ZK provers. The Proof of Verifiable Work (PoVW) consensus mechanism rewards participants with high-performance GPUs for contributing computational power, eliminating reliance on centralized entities.

Zero-knowledge technology, critical for scaling and privacy in blockchain, enables transaction validation without exposing sensitive data. The launch underscores growing institutional interest in ZK infrastructure as Ethereum's ecosystem expands.

SharpLink Gaming Accelerates Ethereum Accumulation with $73M Purchase

Nasdaq-listed SharpLink Gaming has deployed $186.4 million into Ethereum over four days, with its latest $73.25 million acquisition executed through Coinbase Prime. The iGaming firm now holds 62,232 ETH, signaling aggressive institutional adoption during Ethereum's resurgence above $3,000.

Blockchain analytics reveal three concentrated purchases: 21,487 ETH Friday, 16,374 ETH Sunday, and 24,371 ETH Monday. The transactions originated from a high-activity address also interacting with Shiba Inu and Uniswap tokens, suggesting broader crypto market engagement beyond core Ethereum accumulation.

The Minneapolis-based company's pivot from affiliate marketing to digital asset investment mirrors institutional confidence in ETH's long-term valuation prospects. Market observers interpret the buying spree as a strategic positioning ahead of anticipated Ethereum ecosystem growth.

Boundless Network Launches Mainnet Beta on Coinbase's Base, Pioneering Universal ZK Protocol

Boundless Network has unveiled its Mainnet Beta on Coinbase's Base blockchain, marking a significant milestone in zero-knowledge (ZK) infrastructure. The project, backed by RISC Zero's zkVM, introduces what it claims to be the first universal ZK protocol, attracting early adoption from heavyweight players like the Ethereum Foundation, Wormhole, and EigenLayer.

The incentivized testnet features Proof of Verifiable Work, a novel mechanism rewarding participants for generating and validating ZK proofs. This creates a decentralized marketplace for computational integrity, positioning Boundless as a trustless outsourcing hub for blockchains to offload complex verifications.

The launch signals a broader industry shift toward operationalizing ZK proofs across chains. With institutional backing and production-ready infrastructure, Boundless aims to redefine how cryptographic certainty is achieved in decentralized systems.

MicroStrategy's Bitcoin Strategy Yields 20.2% as Whale Activity Intensifies

Michael Saylor's MicroStrategy has bolstered its Bitcoin holdings with a $472.5 million purchase, acquiring 4,225 BTC at an average price of $71,000. The firm now holds 601,550 BTC, valued at approximately $73 billion, reinforcing its position as a dominant corporate holder of the cryptocurrency.

The move is part of a long-term treasury strategy, with Saylor describing bitcoin as a "dependable store of value." MicroStrategy has funded its acquisitions through asset sales, accumulating BTC consistently through market fluctuations.

Bitcoin's surge to a record intraday high of $123,193 has lifted related stocks, with MicroStrategy (MSTR) gaining 4% and Coinbase (COIN) rising 1.8%. The market response underscores growing institutional confidence in Bitcoin as a Core asset.

JPMorgan's Jamie Dimon Signals Deeper Stablecoin Involvement Despite Skepticism

JPMorgan Chase CEO Jamie Dimon revealed plans to expand the bank's stablecoin initiatives while maintaining his characteristic skepticism about their utility. The banking giant will develop both its JPMorgan Depositcoin and explore third-party stablecoins, even as Dimon questioned their advantage over traditional payment systems.

The announcement comes during a watershed moment for stablecoins, with cross-border payments driving adoption in emerging markets. Regulatory tailwinds are strengthening, with the GENIUS Act clearing the Senate and poised for House consideration this week.

Despite Dimon's historical crypto skepticism, JPMorgan has emerged as a blockchain leader. Its private blockchain network now processes $2 billion daily in JPM Coin transactions, while last month's JPMD token pilot on Coinbase's Base network signals growing institutional experimentation.
