Recap: The Raspberry Pi 5 was launched in 2023, delivering more than twice the performance of the previous generation. The board was also instrumental in bringing a small, yet significant change in how the UK foundation is actually printing its single-board computers. By changing the way Raspberry Pi boards are assembled and components are soldered, the maker improved its operations in what it described as “massive” ways.

Raspberry Pi Hardware Engineer Roger Thornton explained the change in a recent blog post. Working with its manufacturing partner Sony, the UK organization gradually implemented a soldering technique known as intrusive reflow soldering.

The new method improved production quality, reduced e-waste, and lowered the company’s environmental impact, Thornton stated.

Intrusive reflow was first used to produce Raspberry Pi 5 boards and is now being applied to earlier models as well. This new manufacturing process resolved the inefficiency issues caused by previous soldering methods, which relied on distinct through-hole connectors and surface mount technology (SMT) machines.

Through-hole connectors require strong solder joints made through the printed circuit board and cannot be handled by the SMT machines that place individual parts.

In the early days of Raspberry Pi production, parts were inserted by hand before being handled by robots. A subsequent soldering step, where boards passed through a molten solder bath, was used to secure everything in place.

The improvements led to a 50 percent reduction in product returns, a 15 percent increase in production speed, and a yearly reduction of 43 tonnes of CO₂ emissions.

The whole process was complex, costly, and time-consuming. Now, thanks to intrusive reflow, through-hole connectors can be placed using the same machines that install SMT parts. Raspberry Pi perfected the method after several trials, adjusting the solder paste stencil and refining the PCB layout until the company’s quality standards were met.

The improvements led to a 50 percent reduction in product returns, a 15 percent increase in production speed, and a yearly reduction of 43 tonnes of CO₂ emissions. Raspberry Pi’s manufacturing now requires less machinery and inventory, with no production line interruptions due to work-in-process inventory.

Raspberry Pi says that intrusive reflow soldering was key to eliminating “wasteful” intermediate steps in the manufacturing process. The company now highlights its reduced environmental impact and improved efficiency, which align with its ongoing efforts to become a more responsible and sustainable organization.

Sustainable energy accounts for more than half of Bitcoin (BTC) mining consumption as of the first quarter, according to the Cambridge Centre for Alternative Finance’s Digital Mining Industry Report. 

Despite higher energy consumption, the industry’s reliance on sustainable energy increased, and operational metrics indicated a push toward long-term resilience through diversification and innovation.

Estimated annual electricity consumption for Bitcoin mining rose to 138 terawatt-hours (TWh), marking a 17% year-over-year increase. Greenhouse gas emissions associated with mining reached 39.8 Million Tons of CO₂e, accounting for 0.08% of global emissions. 

While natural gas remained the largest single energy source at 38.2%, sustainable energy sources such as hydropower and wind combined accounted for 52.4% of the total electricity mix.

North American dominance

The US continued to dominate the global mining landscape, with 75.4% of the reported Bitcoin hash rate originating from the country, while Canada followed with 7.1%.

Emerging mining activity was identified in South America and the Middle East, although North America’s position remains dominant.

The mining hardware market exhibited high concentration levels, with Bitmain holding an 82% market share and the top three manufacturers, Bitmain, MicroBT, and Canaan, collectively controlling over 99% of the market. 

Industry-wide ASIC efficiency improved to 28.2 joules per terahash, reflecting a 24% increase in efficiency compared to the previous year.

Electronic waste (e-waste) remained relatively contained, with 86.9% of decommissioned mining hardware expected to be repurposed or recycled. Estimates pointed to an actual e-waste production of approximately 2.3 kilotonnes for the period assessed.

Miner economics under strain

Electricity accounted for over 80% of miners’ operational expenses, with a median electricity cost of $45 per megawatt-hour and total all-inclusive operating costs averaging $55.50 per megawatt-hour. 

Despite compressing profit margins due to halving impacts, the sector maintained profitability through efficiency gains and power management strategies.

Surveyed miners identified energy price volatility and regulatory uncertainty as their primary concerns. To mitigate these risks, they employed business diversification, geographical expansion, and power hedging strategies. 

The report cited limited deployment capacity and hardware supply chain bottlenecks as the main barriers to industry expansion.

Forecasting data suggested that miners maintained strong predictive capabilities. The median projected year-end 2024 Bitcoin price was $80,500, compared to the actual closing price of $93,390. 

The median network hash rate forecast of 750 exahashes per second (EH/s) closely matched the realized hash rate of 796 EH/s.

New revenue streams and environmental initiatives 

The traditional miner revenue model, which is heavily reliant on block subsidies, faces mounting pressure amid the evolving market conditions.

In response, mining firms have begun diversifying into high-performance computing sectors, particularly servicing artificial intelligence workloads, while also exploring sustainable energy initiatives.

Energy innovation is becoming a core operational focus, and mining firms are increasingly engaging in gas flaring mitigation projects, developing waste heat recovery solutions, and participating in demand response programs to integrate more effectively with power grids.

Approximately 70.8% of surveyed miners reported active engagement in climate mitigation efforts, reflecting an industry-wide push to reduce environmental impact.

The Cambridge report concluded that the Bitcoin mining sector is evolving toward a more sustainable and diversified operational model, driven by technological, economic, and environmental pressures.

Aave has proposed a comprehensive update to its economic framework, focusing on revenue distribution, staking incentives, and liquidity management.

The proposal, introduced by Aave Chan Initiative (ACI) founder Marc Zeller on March 4, is considered a pivotal development in Aave’s evolution. He stated:

“We consider it the most important proposal in our history.”

According to the proposal, Aave has consistently expanded its market presence over the past two years, building a strong financial foundation.

Despite fluctuating market conditions, Aave continues to generate robust revenue, with the DeFi protocol’s liquid reserves surging by 115% to reach $115 million. This strong financial position enables Aave to proceed with its tokenomics upgrade while staying competitive.

A crucial aspect of the proposal is the establishment of the Aave Finance Committee (AFC), a governance-backed entity responsible for managing treasury funds and liquidity strategies.

The AFC will oversee financial allocations within Aave’s ecosystem, ensuring sustainable revenue distribution.

The initiative includes contributions from key stakeholders, including Chaos Labs, TokenLogic, Llamarisk, and ACI.

Buyback strategy

The AFC will manage a six-month AAVE buyback program to enhance token value and ecosystem sustainability, allocating $1 million weekly. Meanwhile, the program may expand based on Aave’s financial health, pending further governance approval.

The AFC can execute purchases directly or collaborate with market makers to acquire AAVE from secondary markets. These tokens will then be distributed to the ecosystem reserve.

TokenLogic, a financial services provider for Aave DAO, will structure buybacks based on the protocol’s overall budget. The goal is to eventually match—and surpass—all protocol expenditures related to AAVE while maintaining a cautious treasury approach.

With new revenue streams expected in 2025, the AFC may propose increasing the buyback budget. TokenLogic will determine which assets finance these purchases, adjusting strategies monthly based on Aave’s treasury composition.

Introducing ‘Umbrella’ for risk mitigation

Aave currently incurs significant liquidity costs, amounting to $27 million annually. To optimize capital efficiency, the proposal suggests consolidating staking and liquidity management under a new system called Umbrella.

This mechanism is designed to provide unmatched protection against bad debt—an area where competitors have largely retreated.

By offering this safeguard, Aave strengthens its position, particularly for institutional participants wary of on-chain risks.

Meanwhile, Umbrella would be integrated across multiple blockchain networks, including Ethereum Mainnet (Core & Prime instances), Avalanche, Sonic, Arbitrum, Gnosis, and the Coinbase-backed Base network.

LEND deprecation

The proposal also seeks to finalize the transition from LEND, Aave’s original governance token, before the 2020 upgrade to AAVE.

The plan involves freezing the LEND migration contract to reclaim 320,000 AAVE tokens valued at approximately $65 million.

The proposal noted that the community had ample time to complete the transition and suggested closing the migration process.

Following this, the DeFi protocol’s governance could decide how to allocate these recovered funds—whether for growth initiatives, security enhancements, or token burns.

Anti-GHO

Aave also proposes launching Anti-GHO, a new rewards mechanism designed to improve incentives for GHO stablecoin holders. This feature would replace the current discount model with a non-transferable ERC20 token.

Anti-GHO would be distributed to AAVE and StkBPT stakers. Holders could burn the token at a 1:1 ratio against GHO debt or convert it into StkGHO.

The issuance of Anti-GHO would be directly linked to revenue generated from GHO. A governance-determined percentage of revenue from GHO facilitators would be allocated toward minting and distributing Anti-GHO.

This approach ensures that incentives remain sustainable and scale proportionally with Aave’s growth.

However, implementing Anti-GHO may require additional development and auditing. The feature could be introduced in a future Aavenomics Part Two proposal.

Europe is on a mission to become more sustainable, and part of that push includes reducing carbon emissions under the European Green Deal. This ambitious strategy aims to reduce pollution and shift the economy toward cleaner resources. This plan is at the heart of measures targeting better product design, efficient resource usage, and improved recycling practices.

According to the Digital Product Passports: A Blockchain-based Perspective report, one of the European Union’s latest ideas for making this happen is the concept of Digital Product Passports (DPPs).

These passports are designed to promote transparency, encourage the responsible use of resources, and help consumers make more informed choices. In this article, we’ll explore how DPPs work and focus on how NFTs can bring transparency and trust to these digital records.

What are Digital Product Passports?

Digital Product Passports, or DPPs, keep track of everything that happens to a product, starting from the moment its raw materials are extracted all the way through manufacturing, shipping, and even recycling. Think of a DPP as a digital file that follows an item through its entire “life,” storing key information such as ingredients, environmental impacts, and repair opportunities.

This system is part of the Ecodesign for Sustainable Products Regulation (ESPR), which pushes manufacturers to design goods with minimal waste and carbon emissions. Another important driver is the Circular Economy Action Plan (CEAP). Both ESPR and CEAP encourage businesses to design products in a way that lets them be reused, repurposed, or recycled—rather than tossed aside.

So, what are the big benefits of DPPs?

  • Transparency: They let people see a product’s sustainability details, like its carbon footprint or whether it uses recycled materials.

  • Circularity: They highlight how easy a product is to repair or recycle, giving products a longer life and reducing waste.

  • Regulatory Compliance: They help companies stay aligned with new EU rules on cutting emissions and managing resources wisely.

Why NFTs?

NFTs, or Non-Fungible Tokens, have gained attention mostly for digital art sales. But their usefulness goes beyond collectibles. Essentially, an NFT is a unique digital certificate that lives on a blockchain. No two NFTs are the same, which makes them excellent for proving that a particular item is one-of-a-kind.

In the world of Digital Product Passports, NFTs can act as digital twins. Imagine a one-to-one digital version of a physical product—like a car part, a battery, or a piece of clothing. Once an NFT is connected to that real-world product, it’s incredibly hard to tamper with the history logged on the blockchain.

This characteristic, called immutability, is key. Blockchains store data in a way that’s permanent, so once something is recorded, it’s nearly impossible to modify it without leaving a trace. On top of that, NFTs can update in real-time to reflect changes in ownership, product repairs, or where and how it gets recycled.

NFT Benefits for Digital Product Passports

Verifiable Proof of Provenance

One of the biggest perks of using NFTs for DPPs is being able to trace a product’s origin. The Digital Product Passports: A Blockchain-based Perspective report describes how certain projects create an NFT for each unit of material to confirm exactly where it was mined and how it moved through the supply chain.

Accountability & Trust

Because a blockchain is shared among many computers (a decentralized ledger), the data it holds isn’t controlled by a single authority. This structure helps build trust: everyone with access can see records of who updated what, and when. That transparency reduces the chance of sneaky alterations or fraud.

Secure Ownership & Transfer

In real life, products often change hands. Maybe you sell your phone or give away a handbag. In an NFT-based DPP system, the transfer of ownership can be instantly documented. The NFT’s transaction history can show who owned it before, making secondhand markets more trustworthy.

Hybrid Privacy Approaches

Not everything can live in plain view on a public blockchain—especially sensitive or competitive data. So, some NFT systems use methods like zero-knowledge proofs (a fancy way of proving you know something without revealing the actual data) or selective disclosure (only revealing parts of the data). This ensures sensitive information stays private while still allowing enough transparency to maintain trust.

Real-World Examples of DPPs using Blockchain Tech

Circularise

  • Focus: Builds blockchain-based supply chain solutions that let manufacturers and recyclers see detailed information about materials. Each product or component is assigned a unique token containing real-time data about its material composition and environmental impact. They are working on using NFTs, decentralized identifiers (DIDs), and verifiable credentials (VCs) to enhance the functionality of DPPs.

Other Industry Pilots

  • Battery Pass & nChain: These rely on private or permissioned blockchains, where only approved members can add or view data. This can be useful for meeting strict EU battery regulations.

  • Spherity emphasises DIDs and verifiable credentials VCs. These tools help verify the identity of whoever’s logging data in the NFT-based passport.

Source Circularise

Challenges & Limitations of NFTs for DPPs

Regulatory Acceptance & Interoperability

Some EU rules might require a QR code on every product, which isn’t the same as an NFT. So, companies need to figure out how to align their NFT approach with official regulations. Different blockchain systems must also work together; otherwise, data could become scattered and incompatible.

NFTs vs. Batch-Level Traceability

NFTs are fantastic for tracking individual items, but they have limits when you want to represent batches of identical products or materials. Technically, you can track multiple units with a single NFT, but that risks “double spending” (using the same token to represent more than the actual amount).

Data Privacy Concerns

European privacy laws (like GDPR) restrict how personal or sensitive information is handled. Simply putting everything “on-chain” might conflict with these rules. That’s why many projects are moving to “hybrid” models, storing some data securely off-chain while keeping ownership records on the blockchain.

User Adoption & Market Skepticism

NFTs became famous for digital art speculation, leading some people to think they’re just hype. Educating manufacturers, consumers, and regulators on how NFTs can actually solve real problems is crucial.

Looking Ahead: The Future of NFTs in DPPs

DPPs may soon combine with other cutting-edge ideas—like IoT sensors that send real-time info on a product’s condition, or AI that sifts through data for insights. NFTs could become smarter too, automatically updating when sensors detect changes (say, a battery’s charge level or wear-and-tear on a machine part).

It’s not just about the EU. Other regions might adopt similar rules to monitor raw material sourcing or limit counterfeit goods. That’s why companies embracing NFT-based DPPs now might gain a competitive edge globally.

The future of product transparency looks bright, but also complex. The Digital Product Passports: A Blockchain-based Perspective report highlights how NFTs tackle core challenges in Digital Product Passports—like ensuring authenticity and tracking ownership—while introducing new considerations around data privacy and cost.

Still, NFTs remain a powerful tool for building transparent, trustworthy product histories. Whether tracing ethically mined cobalt or verifying the recycled content in clothing, NFTs allow all parties to see and trust the same set of facts.
