How blockchain will bridge the divide in 2025

The following is a guest post by Marc Boiron, CEO at Polygon Labs.

In a world of fake news, misinformation and declining faith in traditional institutions, blockchain should bridge the divide by bringing something incredibly powerful and utterly unique to the table: trustlessness. Or, at least, it should. 

Unfortunately, blockchain has always suffered from its own divisions, which have prevented the decentralization revolution from fulfilling its potential. In 2024, things began to change. We saw incredible technical progress to unite the fractured blockchain ecosystem. This year, we’ll finally see decentralization start to deliver its promises of bridging the divide. 

The inevitability of fragmented ecosystems 

If crypto, DeFi and web3 had emerged fully-formed and with a unified, interoperable set of standards, you’d be rightly suspicious. A truly decentralized ecosystem – one that’s not monopolized by a single entity – will be fragmented by its very nature. 

But decentralization came at an initial cost. New technologies and platforms evolved organically and with little reference to (or interoperability with) each other. That left liquidity and functionality trapped in discrete siloes, putting severe limitations on the capabilities and ambitions of individual chains.  

And now for the good news. Some of the brightest minds and most innovative businesses have been working on this problem, and in the last 12 months especially we have made spectacular progress. Together, we are building infrastructure that connects chains, dApps, and communities, and we’re aligning incentives and designing systems that can stand the test of time. 

Most importantly, we’re doing this without betraying the underlying principles of decentralization. 

A world without trade-offs: towards an aggregated future

Layer-2 (L2) networks were supposed to be the silver bullet that solved blockchain’s interoperability and liquidity deficit, but they created as many problems as they solved. It’s true that L2s have boosted transaction capacity, but they remain siloed – even among rollups claiming to be interoperable.

As Vitalik Buterin recently pointed this out, “Ethereum should feel like one ecosystem, not 34 different blockchains.” And that’s a very conservative number; unfortunately, there are more like hundreds of blockchains.

Meanwhile, alternatives like Solana and other alt L1s aim to be so fast and integrated that separate networks won’t be necessary. But here’s the reality: no single chain, no matter how powerful, can handle the full weight of a blockchain-powered Internet. There’s always a ceiling.

We’ve recently seen  major progress towards unification, led by the AggLayer. The AggLayer harnesses zero-knowledge (ZK) proofs to connect chains—L1s, L2s, EVM, SVM and everything else—enabling them to share liquidity, state, and users in a seamless, low-latency, and secure way.

If 2024 was the year of the AggLayer, then 2025 will see them begin to transform the ecosystem, bringing a host of new capabilities and services to a global market. Because rollup clusters can plug into the AggLayer and still interoperate with each other, it creates a system with maximum security, sovereignty, and unity. 

It brings crypto, web3, DeFi and more together into a single “ecosystem of equals”, where each chain’s unique capabilities combine to create something far greater than the sum of its parts.

By using zkEVM or zkVM-powered unification layers, developers can build with lower costs and faster speeds, all while staying anchored to Ethereum’s unmatched security and censorship resistance. At the same time, these protocols are breaking down Web3’s “walled gardens,” allowing ecosystems to share liquidity and work together seamlessly.

This interconnectedness doesn’t just help developers—it benefits everyone in Web3. It creates stronger network effects, making the space more fair, inclusive, and accessible. It brings back the feeling of the Internet, one that feels unified virtually anywhere in the world. And as we head into 2025, this momentum is only growing.

But what does a unified experience actually look like? 

Case study: How yield-bearing stablecoins will reDeFine USD-pegged tokens

One of the prime examples of community-centric trends that saw explosive growth this year is the rapid emergence of yield-bearing stablecoins, such as AUSD and sUSDe. 

Unlike traditional USD-pegged tokens such as USDT or USDC, which are backed by funds invested in low-risk assets, their yield-bearing counterparts share the profits with every holder, so everyone can passively benefit from them — not only the issuer.

By generating yield natively in DeFi as well as through crypto derivatives and traditional finance (TradFi), this new type of stablecoins not only aligns the incentives of all network participants but also benefits from an aggregated approach to blockchain, ensuring seamless interoperability between blockchains.

Once aggregated natively, an asset is available across all blockchains connected to the aggregated network – like the AggLayer. When yield-bearing stablecoins are minted in this manner, they can effectively help further expand and evolve crypto in a fairer and more inclusive manner, incentivizing long-term participation in DeFi and Web3 as a whole. Similarly attractive for professional investors and regular users alike, these assets represent a new dimension of community-first finance, promoting financial inclusion and democratizing access to investment opportunities previously limited to TradFi.

They provide a unique opportunity to earn yield while maintaining exposure to stable assets, making them an attractive option for both seasoned investors and those new to the crypto space. By offering a secure and consistent yield, these stablecoins promote financial inclusion and democratize access to investment opportunities previously limited to traditional finance.

Blockchain’s Bright Future Begins in 2025

Trust in everything from politics to institutions has been steadily eroded for years. Thanks in large part to the digital revolution of the last 30 years, the world is already hopelessly divided. Blockchain offers a compelling alternative future in fields as diverse as finance and digital identity. Until very recently, fragmentation threatened to rob us of these gains

Enabled by the blockchain industry’s paradigm shift toward unification in 2024, these trends are poised to massively accelerate mass adoption by making Web3 financially inclusive and interoperable like never before. Blockchain’s bright future therefore begins anew in 2025, when we’ll see even more innovations that bring historically siloed decentralized ecosystems together as “the Internet of the future.”
