Hyperledger Announces Hyperledger Fabric 2.0

Published

on

 

Hyperledger, an open source collaborative effort created to advance cross-industry blockchain technologies, today announced the general availability of Hyperledger Fabric 2.0. This major release of Hyperledger Fabric, a distributed ledger framework that’s been under development by the Hyperledger community since 2016, delivers a number of features and enhancements needed to increase the efficiency and security of production deployments.

Much of the work on Hyperledger Fabric 2.0 focused on new ways to manage the chaincode (or smart contract) lifecycle to maximize flexibility, remove bottlenecks and create more options to distribute governance. Security and data privacy were also big development priorities, so many features and enhancements are geared towards delivering more granular control of private channels and minimizing vulnerabilities.

Key Hyperledger Fabric 2.0 features include:

Decentralized governance for smart contracts — Hyperledger Fabric 2.0 introduces decentralized governance for chaincode, with a new process for installing a chaincode on your peers and starting it on a channel. The new Fabric chaincode lifecycle allows multiple organizations to come to agreement on the parameters of a chaincode, such as the chaincode endorsement policy, before it can be used to interact with the ledger. The new model offers several improvements over the previous lifecycle, including requiring multiple organizations to agree to the parameters of a chaincode, creating a more deliberate chaincode upgrade process and simplifying endorsement policy and private data collection updates

New chaincode application patterns for collaboration and consensus — The same decentralized methods of coming to agreement that underpin the new chaincode lifecycle management can also be used in your own chaincode applications to ensure organizations consent to data transactions before they are committed to the ledger. Organizations can add automated checks to chaincode functions to validate additional information before endorsing a transaction proposal. Additionally, human decisions can be modeled into a chaincode process that spans multiple transactions. The chaincode may require actors from various organizations to indicate their terms and conditions of agreement in a ledger transaction. Then, a final chaincode proposal can verify that the conditions from all the individual transactors are met, and “settle” the business transaction with finality across all channel members.

External chaincode launcher —The external chaincode launcher feature empowers operators to build and launch chaincode with the technology of their choice. Use of external builders and launchers is not required as the default behavior builds and runs chaincode in the same manner as prior releases using the Docker API.

Private data enhancements — Hyperledger Fabric 2.0 enables new patterns for working with and sharing private data, without the requirement of creating private data collections for all combinations of channel members that may want to transact. Specifically, instead of sharing private data within a collection of multiple members, you may want to share private data across collections at a transaction or state key level with selected channel members. Each private data collection may contain a single organization, or perhaps a single organization along with a regulator or auditor.

State database cache for improved performance on CouchDB — When using external CouchDB state database, read delays during endorsement and validation phases have historically been a performance bottleneck. With Hyperledger Fabric 2.0, a new peer cache replaces many of these expensive lookups with fast local cache reads.

Alpine-based docker images — Starting with 2.0, Hyperledger Fabric Docker images will use Alpine Linux, a security-oriented, lightweight Linux distribution. This means that Docker images are now much smaller, providing faster download and startup times, as well as taking up less disk space on host systems. Alpine Linux is designed from the ground up with security in mind, and the minimalist nature of the Alpine distribution greatly reduces the risk of security vulnerabilities.

In an era defined by rapid innovation and ever-shifting regulatory landscapes, blockchain continues to prove its mettle across diverse sectors—from data privacy and prediction markets to gaming and sustainable development. Today in Blockchain, we explore five major developments shaping the decentralized world on April 24, 2025:

  1. Europe’s New Privacy Guidelines: How the EDPB’s draft rules may redefine on-chain data handling.

  2. Canada’s Blockchain Advantage: Lessons from Consensus Toronto on agility, talent, and national strategy.

  3. Prediction Markets for Science: DeSci’s leap toward crowdsourced validation and the reproducibility crisis.

  4. Ubisoft’s NFT Gaming Gamble: Yet another Web3 pivot in mainstream video games—and why it matters.

  5. Blockchain for Good Accelerator: The UNDP joins forces with the Blockchain for Good Alliance to fuel SDG-focused innovation.

This op-ed–style briefing strips away the noise to deliver concise yet detailed coverage, incisive commentary, and big-picture implications for developers, entrepreneurs, regulators, and enthusiasts alike. Strap in as we decode today’s key blockchain headlines.


1. Europe’s Data Privacy Guardrails: EDPB’s Draft Blockchain Guidelines

What happened:
On April 22, 2025, the European Data Protection Board (EDPB) published draft guidelines clarifying how personal data must be stored and accessed on blockchain networks to comply with the General Data Protection Regulation (GDPR). Key takeaways include:

Advertisement
  • Minimize on-chain data: Avoid embedding personally identifiable information directly into immutable ledgers.

  • Data Protection by Design & by Default: Mandate early-stage DPIAs (Data Protection Impact Assessments) for any blockchain project touching personal data.

  • Controlled access & erasure mechanisms: Develop off-chain storage layers and governance protocols to satisfy “right to rectification” and “right to be forgotten” requirements.

Source: Decrypt

Why it matters:
GDPR’s foundational principles clash with blockchain’s inherent immutability and transparency. By issuing these guidelines, the EDPB seeks to preserve individual privacy rights without stifling decentralized innovation. However, the tension between censorship-resistant networks and regulator-mandated mutability raises profound design challenges.

Analysis & Commentary:
Today’s guidance is overdue but pivotal. As Bryn Bennett of Hacken reminds us, “Privacy isn’t an add-on—it’s infrastructure.” Projects that ignore privacy-by-design risk not only fines but also eroded user trust. Conversely, decentralized privacy pioneers like Nym Technologies warn that retrofitting GDPR onto public blockchains can compromise both privacy and sovereignty. In my view, the next frontier lies in hybrid architectures—leveraging off-chain zero-knowledge proofs, secure enclaves, and permissioned sidechains—to reconcile transparency with confidentiality. Europe’s blueprint could become a global reference, influencing regulators in Asia-Pacific, North America, and beyond to articulate their own blockchain-specific data rules.


2. Canada’s Blockchain Advantage: Small Enough to Move Fast, Big Enough to Matter

What happened:
At Consensus Toronto 2025, CoinDesk columnist William Mougayar argued that Canada is uniquely positioned to outpace other G7 nations in blockchain adoption, thanks to:

  • Homegrown talent & heritage: Ethereum’s origins in Toronto and thriving developer ecosystems in Montreal and Vancouver.

  • Regulatory agility: Streamlined federal-provincial coordination, pro-innovation tax credits, and pilot sandbox frameworks.

  • Strategic national vision: Proposals to mandate crypto access in Canadian banks, integrate digital assets into capital markets, and even explore a national cryptocurrency reserve.

Why it matters:
While the U.S. grapples with interagency turf wars between the SEC, CFTC, and others, Canada’s structural simplicity offers a template for coherent blockchain policymaking. This could accelerate capital inflows, enterprise pilots, and global competition for fintech talent.

Analysis & Commentary:
Canada’s playbook hinges on being “small enough to pivot, yet big enough to impact”. As blockchain matures beyond niche use cases, national champions will emerge from jurisdictions that marry regulatory clarity with creative incentives. I predict that within two years, Toronto and Montreal will rival Miami and Dubai as leading hubs for DeFi, tokenization, and digital-asset custody. But execution is everything—if Canada can streamline licensing, shore up AML/CTF safeguards, and embed digital literacy into its education system, it could truly leapfrog entrenched incumbents.


3. Prediction Markets in Science: DeSci’s Bold Experiment

What happened:
In an opinion piece for Cointelegraph, Dr. Sasha Shilina explored how blockchain-powered prediction markets (e.g., Polymarket, Pump.science) are being repurposed to address the scientific reproducibility crisis. Highlights include:

  • Crowdsourced forecasting: Researchers and investors stake tokens to bet on experimental outcomes, incentivizing rigorous study design.

  • Financial accountability: Monetary losses for flawed work create a rapid feedback loop, potentially weeding out irreproducible findings.

  • Regulatory hurdles: Jurisdictions still classify these markets as gambling, complicating mainstream adoption.

Source: Cointelegraph

Why it matters:
Traditional peer review can take months or years to expose methodological flaws. Decentralized prediction markets promise near-real-time validation, democratizing scientific oversight and reducing wasteful replication studies.

Analysis & Commentary:
Prediction markets offer an “open-science complement”—not a replacement—to scholarly publishing. By aligning economic incentives with truth-seeking, they could elevate data integrity and funders’ confidence. However, unchecked speculation risks gaming the system, especially if liquidity pools are dominated by a handful of whales. The solution lies in multi-stakeholder governance: academic consortia, journal publishers, and veteran researchers collaborating to set market parameters, oracle standards, and dispute-resolution mechanisms. In my view, the coming year will determine whether DeSci moves from proof-of-concept to institutional legitimacy—or remains a fascinating experiment.


4. Ubisoft’s NFT Gaming Bet: Might & Magic Fates

What happened:
On April 24, 2025, gaming giant Ubisoft announced Might & Magic Fates, its third blockchain game in under six months, developed in partnership with Immutable. Key features:

  • NFT trading cards: Creatures, spells, and artifacts minted as on-chain assets.

  • Optional Web3 layer: Players can choose between traditional gameplay or unlocking digital ownership via NFTs.

  • Community backlash: Early reactions decry “Web3 slop,” with seasoned gamers lamenting lack of gameplay previews.

Source: 80 Level

Why it matters:
Ubisoft’s persistence underscores a broader corporate push into play-to-earn and digital-ownership models. Despite vocal skepticism, top publishers see NFTs as a path to new revenue streams and player engagement metrics.

Analysis & Commentary:
I admire Ubisoft’s willingness to iterate—but will “third time be the charm”? Past misfires suggest they’ve yet to nail the balance between token mechanics and fun. If Fates can deliver rich narrative, balanced tokenomics, and genuine secondary-market value, it might convert skeptics. Otherwise, gamers will continue associating NFTs with pump-and-dump schemes. Successful blockchain gaming will require tight integration of on-chain assets with deep, off-chain gameplay loops—think on-chain skins that evolve with player achievements or governance tokens that shape in-game lore. Ubisoft’s true test will be fostering an ecosystem where NFT ownership enhances, rather than distracts from, core gameplay.

5. Blockchain for Good: UNDP & Alliance Launch Global Accelerator

What happened:
The Blockchain for Good Alliance (BGA), in partnership with the United Nations Development Programme (UNDP) and EMURGO Labs, launched the SDG Blockchain Accelerator on April 24, 2025. Program highlights:

  • 4-month accelerator: Tailored training, mentorship, and technical support via UNDP AltFinLab and EMURGO Labs.

  • Multi-chain innovation: Encourages solutions across Cardano, Ethereum, and other protocols.

  • Up to $1.5 million in post-acceleration grants: Equity-free funding to scale blockchain solutions addressing the UN’s 17 Sustainable Development Goals (SDGs).

Source: UNDP Innovation

Why it matters:
This initiative bridges Web3 technology with humanitarian impact, channeling blockchain’s transparency and efficiency into real-world challenges—financial inclusion, supply-chain traceability, carbon credits, and more.

Analysis & Commentary:
SDG-focused accelerators signal a shift from speculative token swaps to impact-driven development. By equipping UNDP personnel and global innovators with blockchain toolkits, the program can catalyze projects that deliver measurable social value. Success stories—like transparent vaccine distribution chains or micro-loan platforms for underserved communities—will validate blockchain’s promise beyond hype cycles. I urge stakeholders to watch for pilots that blend on-chain verification with off-chain delivery, ensuring that funding flows transparently and outcomes are independently audited. If this Alliance proves out, it could redefine public-private partnerships in digital development.

World Chess and the Algorand Foundation propose leveling the playing field with a “chess passport”

Published

on

world-chess-and-the-algorand-foundation-propose-leveling-the-playing-field-with-a-“chess-passport”

 

In a whitepaper published today, World Chess (LSE: CHSS) and the Algorand Foundation (ALGO) conceptualize a new blockchain-based system that would establish secure, private, and verifiable credentials for global sports organizations, including chess. Grandmaster Evgenij Miroshnichenko contributed to the paper alongside the Algorand Foundation and World Chess.

The move comes as interest in chess hits a new high, driven by popular television series on Netflix and the BBC, the 2024 awarding of the youngest-ever world chess champion, and the inclusion of chess for the first time in the Esports World Cup later this year.

If adopted, the system would allow chess players to independently manage their identity and credentials across all chess platforms and organizations with a single decentralized ID, and one login credential for everywhere they play. They could then easily “port” their identity, achievements, records of play, rankings, and rewards across online chess platforms, as well as seamlessly from the digital world to in-person games and tournaments. This provides them with a much easier way to prove their identity, no matter their status or documentation; it would also reduce tournament application times significantly. Chess organizations would then be able to welcome even more players to their competitions, including those who have built their chess career solely online, as well as players who have previously only competed in tournaments held by other organizations.

Among other benefits, the adoption of a “global chess passport” would make it much easier for organizers and chess clubs and federations alike to onboard and register players, both online and offline.

Another benefit of the proposed system is to safeguard fair play. As chess becomes increasingly integrated into e-sports and online competitions, the use of AI programs or player fraud (one player representing another) is an increasing concern. Being able to confirm player integrity (including whether they have been banned for cheating on any other platform) ensures credibility of chess contests and competitions. These verifiable credentials also preserve player privacy. They can be used to confirm player eligibility and relevant identity data without providing access to sensitive documentation, such as passports. Finally, identity verification also prevents fraud in tournament payouts. Phishing and other attempts to steal winnings are on the rise; this ensures only the rightful winner can access their prize funds.

“I think that chess needs its version of the global e-version of drivers license. It’s a global game, and using blockchain for the benefit of having one universal independently verifiable ID is something that both players and organizers will certainly benefit from,” says Ilya Merenzon, CEO of World Chess.

“This initiative is not just about chess; it’s about the future of fair play and verifiable achievement across all sports and esports,” said Bruno Martins, principal architect at the Algorand Foundation and co-author of the whitepaper. “Chess has a rich history of proving the usefulness of new technologies. In this case, World Chess is showing the integrity, privacy, and portability of records in any competitive arena is not only possible – it’s in the best interest of every player, everywhere.”

Statista estimates that the market for esports should reach $4.8 billion in 2025, with nearly 900 million players by 2029 (source), all of which could benefit from better cross-platform registration for online and in-person competitions.
