David Chaum Announces the xx coin, Supporting Decentralized Messaging, Payments and dApps on the xx network

Cryptography pioneer David Chaum today announced the xx coin, a digital currency that will support decentralized messaging, payments, and dApps on the xx network. xx coin technical details and plans for distribution will be revealed next week at a commemorative event at the National Research Institute for Mathematics and Computer Science, the home of Chaum’s original crypto research group in Amsterdam.
“The xx coin and xx network will serve smartphone users and dApp developers by harnessing both the metadata-shredding anonymity and privacy of Elixxir and the security, speed and scalability of Praxxis,” said Chaum. “By successfully bringing the projects together, the xx network resolves the tension between speed/scale and privacy/security.”
Early supporters (but not US persons) who download the xx collective smartphone app prior to the release of the xx network whitepaper will be eligible for certain benefits entitling them to greater participation in the xx network. Details for eligible participants can be found at xx-coin.io.
The xx network was designed in response to growing public concern for user privacy as well as the emerging threat of quantum computing. The Elixxir cMix network layer provides groundbreaking privacy and security by shredding user metadata. Praxxis provides a denominated coin structure that breaks payments into individual coins to provide privacy, and distinctive hash-based cryptography, which is secure against attacks from current nation-state adversaries and future quantum computers.
The staged launch of the xx network has begun. The xx network public alpha currently supports the xx messenger, an Elixxir dApp that provides unprecedented user privacy by preventing observers from collecting metadata. The xx network beta, scheduled for release in early 2020, will provide deeper integration between Elixxir and Praxxis and run on 600 independent nodes that were selected earlier this year.
“For all of us to feel comfortable online with the more important and sometimes sensitive parts of our lives, we need money with financial privacy and security to conduct our affairs,” said William Carter, COO of Praxxis. “And to support users worldwide we need low-latency, high-speed performance at scale. The xx coin provides a way for Praxxis and Elixxir software to achieve these goals running on the decentralized xx network. Next step is beta!”

1. Deloitte Predicts $4 Trillion Tokenized Real-Estate Market by 2035
Summary:
In a landmark report released April 28, consulting giant Deloitte projects that the tokenized real-estate market could swell to $4 trillion by 2035. The forecast hinges on rapid adoption of security tokens that fractionalize property ownership, enabling global investors to trade real-estate assets 24/7 on blockchain platforms. Deloitte identifies five key enablers: regulatory clarity, standardized token protocols, interoperability layers, institutional-grade custody services, and liquid secondary markets. Adoption drivers include enhanced liquidity, democratized access for retail investors, and lower transaction costs via smart contracts.
Analysis & Opinion:
Tokenization stands at the confluence of DeFi and traditional finance, promising to unlock trillions in illiquid assets. Yet realizing a $4 trillion market requires overcoming persistent hurdles: cross-border regulatory alignment, KYC/AML compliance on decentralized platforms, and robust digital-asset custodianship. Real-estate incumbents should prioritize pilot programs in regulated jurisdictions—such as Switzerland’s FINMA sandbox—to build trust and test token standards like ERC-3643 or the upcoming ISO TC 307 specifications. Meanwhile, DeFi protocols must integrate real-world asset oracles with high-assurance data feeds to prevent valuation discrepancies. As major asset managers—BlackRock, Fidelity—eye tokenization pilots, blockchain platforms offering modular compliance and seamless fiat on-ramps will emerge as market leaders.

2. TRON DAO Empowers Emerging Talent at Harvard Blockchain Conference 2025
Summary:
TRON DAO reaffirmed its commitment to education and Web3 innovation by sponsoring the Harvard Blockchain Conference 2025 on April 26–27. The foundation underwrote travel grants, speaker honoraria, and hackathon prizes to support students and researchers exploring DeFi, NFT interoperability, and decentralized governance. TRON representatives—including CTO Michael Kong—led deep-dive sessions on TRON’s latest EVM-compatible upgrades, zero-fee transactions, and cross-chain bridges powered by the Sun Network. Award winners gained access to the TRON Accelerator program, offering mentorship, developer grants, and potential seed funding.
Analysis & Opinion:
Educational sponsorship is a strategic play for protocols seeking long-term developer mindshare. By investing in Harvard’s brightest, TRON DAO not only promotes its Layer 1 ecosystem but also fosters innovations that could address TRON’s scalability, security, and decentralization trade-offs. However, high-profile academically oriented conferences risk echo-chamber effects unless participation spans beyond marquee institutions. TRON would benefit from parallel outreach to Historically Black Colleges and Universities (HBCUs) and community colleges to diversify its developer pipeline. In the battle for EVM-compatible supremacy, protocols that nurture broad, inclusive communities will secure resilience and real-world network effects.

3. Miden Raises $25 Million to Scale a ZK Blockchain Post-Polygon Spin-out
Summary:
Miden, the zero-knowledge (ZK) proof–based Layer 2 protocol spun out of Polygon in late 2024, has secured a $25 million Series A led by a16z Crypto and Electric Capital. The round also saw participation from Placeholder, Pantera, and Circle Ventures. Miden’s core innovation lies in its bespoke STARK-based prover that enables trustless off-chain transaction batching and on-chain proof verification. Unlike SNARK-focused rollups, Miden eschews trusted setups and prioritizes transparency while targeting throughputs of 4,000+ TPS. The funds will scale Miden’s developer ecosystem, strengthen its modular data availability layer, and accelerate mainnet launch slated for Q4 2025.
Analysis & Opinion:
The ZK-rollup wars are intensifying as projects differentiate on security assumptions, throughput, and developer experience. Miden’s STARK-centric architecture addresses growing community concerns over SNARK trusted setups and prover centralization. However, achieving 4,000 TPS in production demands optimizations at both protocol and EVM-compatibility layers. Miden must also articulate clear interoperability roadmaps with Ethereum, Cosmos, and the OP Stack to attract DApp teams wary of liquidity fragmentation. The $25 million war chest affords aggressive grant programs and bug bounties—critical to securing audit-hardened code—but community trust will hinge on transparent security reports and gradual mainnet roll-out through incentivized testnets.

4. JPMorgan Partners with Nacha for Blockchain-Backed ACH Account Validation
Summary:
In a first for the traditional banking sector, JPMorgan Chase announced on April 27 a strategic alliance with Nacha, the U.S. ACH network operator, to pilot a blockchain-enabled account validation service. Utilizing a private permissioned ledger based on Hyperledger Fabric, the initiative aims to streamline ACH origination by verifying account ownership in real time, thereby reducing failed transactions and fraud. Pilot participants—including fintechs, regional banks, and corporate treasuries—can request instant validation tokens on ledgers, with JPMorgan acting as the initial node operator and Nacha providing rule governance. The project targets a 50% reduction in ACH settlement delays and a projected $300 million annual saving in transaction costs.
Analysis & Opinion:
Legacy payment rails face mounting pressure from DeFi protocols offering near-instant, low-fee transfers. JPMorgan’s move to integrate blockchain into ACH validation is a pre-emptive strike to modernize the Automated Clearing House network from within. Success will depend on achieving network effects—convincing enough U.S. financial institutions to run nodes and accept blockchain-issued trust tokens. Clear regulatory guidance from the Federal Reserve and CFPB on ledger governance will be essential. Should this pilot prove scalable, it could catalyze broader on-chain rails for corporate payments, payroll, and supply-chain finance, bridging Web2 and Web3 infrastructures.

5. Nuvve Launches New Subsidiary to Capitalize on Cryptocurrency and Blockchain Opportunities
Summary:
Electric-vehicle charging network operator Nuvve has formed Nuvve Blockchain Ventures—a dedicated subsidiary focused on integrating cryptocurrency, distributed-energy resources (DERs), and tokenization into grid services. Announced April 28 via Business Wire, the new entity will explore utility partnerships for vehicle-to-grid (V2G) settlement in stablecoins, energy-asset tokenization for peer-to-peer trading, and use of NFTs to represent renewable-energy credits (RECs). Nuvve Blockchain Ventures has already secured MoUs with three major U.S. utilities and plans a Q3 pilot using a Polygon-based sidechain for meter-to-meter settlement.
Analysis & Opinion:
Nuvve’s leap into blockchain underscores the cross-industry potential of tokenization and DeFi primitives. By transacting energy services in stablecoins, Nuvve can reduce cross-border FX risk for EV fleets and unlock micro-grid autonomy. However, real-world energy markets demand high-availability, low-latency settlement—areas where existing Layer 1s and busy sidechains may falter. The choice of Polygon sidechain offers low fees and Ethereum security but may require roll-up bridges to settle larger energy-credit batches on Ethereum mainnet. Regulatory clarity on energy tokens as securities or commodities will also shape adoption. If Nuvve succeeds, utilities could adopt blockchain for everything from demand-response auctions to carbon-credit trading, accelerating the energy-Web3 nexus.
