Network news

BASED ROLLUPS TO THE RESCUE: In recent years, Ethereum has embraced a layer-2 scaling roadmap—a plan that encouraged the development of third-party auxiliary networks called «layer-2 rollups»—to help scale the base Ethereum ecosystem. Offloading activity to these upstart networks has helped bring down fees and improve speeds for end-users, but it has led to a massive, deeply fragmented ecosystem of layer 2s. But while layer-2 networks all post data back down to Ethereum, they often struggle to communicate directly with one another, meaning passing assets and data between them can become expensive and cumbersome. There’s also the risk of centralized sequencers: reliance on company-controlled black boxes to pass transaction data between blockchain layers. As a result, some Ethereum developers are pushing rollup tech that takes a new approach to security and interoperability: “based rollups.» Based rollups differ from most existing rollups because they shift execution duties—such as processing transactions—back to Ethereum’s layer-1 rather than handling them on a separate layer-2 network. When someone transacts on a layer-2 rollup, their transaction is processed through a component called a “sequencer.” The sequencer batches multiple transactions and submits them to Ethereum for settlement. While sequencers provide efficiency and generate revenue for rollup operators by strategically ordering transactions, they also introduce a single point of failure. Based rollups avoid this vulnerability by using Ethereum’s built-in sequencing—its massive community of validators—rather than a single centralized sequencer. Rollups like Optimism, Arbitrum, Base, zkSync, and Blast have quickly grown to support larger transaction volumes than Ethereum itself. According to L2Beat, there are currently 140 live layer-2 networks, but the experience of operating between them—passing assets and other data between networks—has become clunky. As Ethereum becomes bigger and layer-2 networks become more integral to its functioning, improving communication between layer-2s—in other words, improving «composability»—has become more important than ever. — Margaux Nijkerk Read more.

LIDO GOES MODULAR: The developers behind Lido, the largest staking service on Ethereum, have proposed revamping the staking platform with modular «vaults.» The new framework would introduce stVaults, a customizable component designed to help Lido accommodate institutions and more complex staking strategies. Lido currently allows investors to pool their ether (ETH) together and «stake» their crypto — locking up their tokens with the network, helping to secure it in exchange for interest. Lido pioneered liquid staking: users get a receipt on their deposits called Lido staked ETH (stETH) that they can trade at any time. With liquid staking on Lido, entering and exiting staking positions became as simple as buying and selling stETH tokens. Lido V3’s stVaults are “modular smart contracts designed to meet the diverse and evolving needs of Ethereum participants,” according to a press release shared with CoinDesk. The upgrade would enable staking setups beyond cut-and-dry liquid staking. Specifically, stVaults will be able to help institutional stakers who want to personalize their staking setups, node operators who want to attract high-volume stakers, and asset managers who want to create new staking use cases. “What is important to understand with customizable infrastructure, is that you can in general build even more complex products,” said Konstantin Lomashuk, the founder of the Lido staking protocol. — Margaux Nijkerk Read more.

UNICHAIN FINALLY: Uniswap Labs, the primary developer behind one of the largest decentralized exchanges (DEX), Uniswap, shared Feb 13 that its long-awaited layer-2 network, Unichain, is now live. Powered by Optimism’s OP stack, Unichain—like other layer-2s on Ethereum—offers faster and cheaper transactions compared to Ethereum’s mainnet. Developers can deploy apps onto the network, which has been optimized specifically for decentralized finance (DeFi) and aims to serve as «the home for liquidity across chains,» according to Uniswap Labs. For Uniswap Labs, the benefit of launching a layer-2 is twofold: it will provide a better experience for users of Uniswap and similar platforms, and it will create a new revenue opportunity in the form of network fees. A representative for Uniswap Labs told CoinDesk that «around 20%» of the chain’s revenue will go directly to the company. Unichain has been in testing since October 2024 and is classified by Uniswap Labs as a «stage-1» rollup, meaning it has elements of decentralization but retains some centrally-controlled safeguards at this early phase. The network is built on the OP Stack, a modular framework that lets developers build interoperable layer-2 chains based on Optimism’s optimistic rollup technology. Several well-known teams have come out with their own OP Stack-based layer-2’s, including Coinbase’s ‘Base’, Kraken’s ‘Ink,’ World’s ‘World chain,’ and Sony’s ‘Soneium.’ “We are anticipating a world of many, many different use cases, of which trading is a small subset,” Adams told CoinDesk in an interview. In collaboration with Ethereum research and development firm Flashbots, the Uniswap team said it has created a Trusted Execution Environment (TEE) on Unichain, a secure area for more sensitive transactions and is meant to optimize the chain for DeFi by allowing for more advanced trades and faster transaction finality. — Margaux Nijkerk Read more.

PECTRA IN APRIL: Ethereum developers have officially set test dates for Pectra, the network’s first upgrade in 11 months, putting it on track for a potential April release date. Pectra will contain an array of improvements — with a special focus on wallets and validators — but it comes at a period of heightened scrutiny for Ethereum, which has recently faced pressure from its community to refocus and catch up with competitors. Ethereum’s core builders decided on Thursday during their bi-weekly «All Core Developers» call to begin testing Pectra on Feb. 26 on the Holesky testnet, with a follow-up test on the network’s Sepolia testnet slated for Mar. 5. Should those tests succeed, the developers will reconvene on Mar. 6 to determine when to launch the upgrade officially. According to Tim Beiko, the protocol support lead at the Ethereum Foundation, developers expect the upgrade to hit mainnet in early April. Pectra — a portmanteau representing two separate upgrades, Prague and Electra — includes eight major improvements to the second-largest blockchain. Among the most-anticipated is EIP-7702, which is supposed to improve the user experience of crypto wallets. The Ethereum community has been facing an identity crisis over the last few weeks. Its native token, ether (ETH), is underperforming against other cryptocurrencies, and competitor networks like Solana have drawn attention and talent from the Ethereum ecosystem — the first-ever programmable blockchain and still the most trafficked. Amid the controversy — much of it directed at the Etheruem Foundation, which coordinates chain upgrades and is currently undergoing a major leadership shuffle — developers are hoping that Pectra will help put the network on steadier footing. — Margaux Nijkerk Read more.

5 Ways the SEC Can Embrace Innovation

Published

on

By

The U.S. Securities and Exchange Commission has long been the world’s most influential financial regulator, helping to ensure our capital markets are the deepest, fairest, and most accessible in the world. But its continued relevance will depend on whether it can do more than merely respond to innovation — it must proactively foster it.

For nearly a century, the SEC has adapted to evolving markets, new technologies and greater retail participation. In its best moments, the agency has embraced innovation in service of transparency, investor protection, and capital formation. But in recent years, it has strayed from that legacy — nowhere more visibly than in its approach to crypto and blockchain.

The good news is, with a change in leadership and a more open posture emerging, the SEC has a chance to course-correct. But the bigger question is: how do we make that change permanent? How do we build innovation into the SEC’s DNA so that the next promising financial technology isn’t strangled in its crib?

I spent nearly six years at the SEC, first as a Senior Counsel in the Division of Enforcement and then as Chief Counsel in the Office of Legislative and Intergovernmental Affairs. I’ve since held senior legal and policy roles in crypto firms across the ecosystem. From both perspectives, one thing is clear: the SEC can fulfill its mission more effectively — and maintain its global leadership — only if it becomes a proactive partner in financial innovation.

The SEC at Its Best

The SEC has a proud history of embracing change to the benefit of investors and markets alike. In the 1990s, it digitized corporate filings through EDGAR, replacing paper documents with searchable databases. It later approved Regulation ATS, enabling the rise of alternative trading systems that increased competition and liquidity. ETFs, which were once novel, are now mainstream products that offer low-cost, diversified exposure to a wide range of assets. More recently, fractional-share trading has empowered millions of retail investors to own a slice of companies they once could only admire from afar.

One especially relevant example as the SEC thinks about how to regulate crypto is the agency’s treatment of asset-backed securities. In the 1980s and 1990s, the SEC recognized that these complex financial products didn’t fit neatly into existing disclosure regimes. After years of study and no-action letters, it developed a tailored disclosure framework in 2004 — refined further in 2014 — that balanced innovation with investor protection. And it didn’t need to bring hundreds of enforcement actions to do it.

When the SEC Fell Behind

There are also times the SEC failed to adapt, to the detriment of both investors and markets. It was slow to respond to the rise of high-frequency trading, contributing to the 2010 Flash Crash. It took years to implement the crowdfunding rules authorized by the JOBS Act. It lagged on digital reporting standards, delaying broader access to market data.

And, for much of the last few years, its stance on crypto veered from caution to outright hostility. Instead of issuing clear rules for digital assets, the agency pursued a scattershot enforcement campaign — often against firms that were seeking to comply in good faith. Many of these actions didn’t even involve fraud or investor loss. Meanwhile, American crypto companies fled overseas, and a global industry flourished without us.

Even the SEC’s grudging approval of spot bitcoin ETFs in 2024 came only after it was forced by a federal court. And while the agency at one point talked about creating a crypto disclosure framework akin to what it did for ABS, it never followed through.

Innovation Isn’t the Enemy

Crypto may be new, but the SEC has faced this challenge before. It knows how to modernize its rules to meet new realities. What’s different now is the opportunity to leverage innovation — not just regulate it.

Take blockchain technology. It could enable near-instant trade settlement, reducing risk and freeing up capital. It could improve market transparency through immutable records and real-time transaction data. It could lower operational costs by reducing intermediaries. And tokenization could expand access to private markets and hard-to-reach asset classes, benefiting both issuers and investors.

Ironically, the SEC hasn’t seriously explored how blockchain could improve its own market oversight. That’s a missed opportunity. But it’s not too late.

A Blueprint for the Future

So what would it look like to build innovation into the SEC’s core mission?

  • Revise the SEC’s Mandate: Congress should amend the Securities Exchange Act of 1934 to explicitly include the promotion of innovation and modernization, alongside investor protection, market integrity, and capital formation.
  • Rethink Metrics of Success: The SEC shouldn’t measure success solely by the number of enforcement actions or penalties collected. It should also look to capital formation, investor confidence, and the safe adoption of new technologies.
  • Create an Innovation Office: A dedicated, empowered team should engage with entrepreneurs, technologists, and academics to guide responsible innovation — just as similar offices in the U.K. and Singapore have done.
  • Adopt Risk-Based Regulation: Not every new product or platform needs full regulatory treatment on day one. Pilot programs, safe harbors, and regulatory sandboxes can help innovators test ideas while maintaining appropriate guardrails.
  • Invest in Education and Training: SEC staff need better fluency in emerging technologies. Cross-disciplinary expertise should be rewarded and cultivated.

These are not radical ideas — they are proven tools drawn from the SEC’s own playbook.

In a global race to define the future of finance, the SEC has a choice: lead or fall behind. Its greatest strength has always been its credibility and ability to adapt.

The next generation of investors and entrepreneurs won’t wait around for 20th-century rules to catch up to 21st-century innovation. Nor should they have to. If the SEC wants to remain the gold standard, it must adapt once again — not just to the present, but to what comes next.

Is ETH Still Special?

Published

on

By

We are never shy about holding ETH to account as crypto’s second largest asset and the DeFi intuition gateway for traditional investors. But mainstream adoption requires a growth story, and so far this year ETH is (put kindly) failing to lead.

ETH sits in 16th place in the CoinDesk 20 YTD performance leaderboard, down 53%. Going back a year, the numbers look similar: 15th place and down 50%. Its market cap has dwindled so much relative to XRP that both are expected to be capped in the upcoming CoinDesk 20 reconstitution, a first.

(CoinDesk Indices)

ETH’s woes are news to few in the industry, but for us as index and product builders for «5%-ers,» it begs the question: is ETH still special? A distinguished provenance can only take you so far. ETH continues to dominate its on-chain categories (even before adding in L2s) and is arguably the second best brand name in crypto. There are even thoughtful ideas about ETH’s end-state as an essential supporting component of our blockchain future; we hear expressions like, «Ethereum will be the clearinghouse of DeFi.»

But mainstream adoption requires a growth story.

We have observed over the last few weeks that bitcoin has shown impressive resilience to fragile global markets. This past week was no exception, and as we pointed out last week, expectations for higher inflation – now echoed by Fed Chair Powell – could help support movement into bitcoin.

But the crypto market’s dependency on bitcoin to lead prices higher is one we hope the digital asset class outgrows. ETH can reassert a leadership position, as it briefly did in the weeks following the U.S. election. If not, CoinDesk 20 investors have exposure to much of ETH’s competition.

GSR Anchors $100M Investment in Upexi to Purchase SOL, Stock Rockets 700%

Published

on

By

Crypto trading firm GSR led a $100 million private placement into Upexi (UPXI), a consumer-goods company pivoting to a digital asset-based treasury strategy.

The company, whose products include medicinal mushroom gummies and pet-grooming tools, said it will use the capital to accumulate and stake solana (SOL) tokens. The Tampa, Florida-based company had a market cap of $3 million on Friday.

The investment, structured as a private investment in public equity (PIPE), comes as Upexi shifts from physical product manufacturing to managing part of its balance sheet using Solana, a high-speed blockchain known for low fees and fast settlement, according to a press release.

The investment announcement sent Upexi’s stock soaring more than 700%, from around $2.30 to $19 at the time of writing.

GSR’s involvement points to a growing overlap between public markets and blockchain finance.

“This investment highlights the growing demand for efficient, secure access to high-quality crypto assets in public markets” Brian Rudick, GSR’s head of research, said in a statement.

Solana Foundation president Lily Liu said the deal marked another step in connecting traditional financial firms with decentralized infrastructure.

The move “underscores GSR’s confidence in Solana as a leading high-performance blockchain,” the finance company said in a release.
