Ethereum and Solana entered 2026 having built the technical and market groundwork for a potential DeFi reboot. Ethereum’s 2025 momentum came from growing institutional adoption and steady scaling work, while Solana focused on stress‑testing and infrastructure improvements under real demand. Both trends matter because they change how fast, cheap, and interoperable decentralized finance can become for projects and users.
Ethereum’s 2026 Push Towards Interoperability
In 2025 Ethereum’s advance was driven in large part by greater institutional involvement, where spot ETFs helped accelerate the emergence of digital asset treasuries (DATs). Mike Silagadze, cofounder of ether.fi, highlighted protocol‑level improvements and said the network is concentrating on “making the Ethereum mainnet layer one more scalable,” with work on cheaper transactions and better layer‑two interoperability. Those developments pair with a broader push to reduce fragmentation across layer twos, a theme Alex Cutler of Dromos Labs summarized as “unification,” and that combination is positioned to change how liquidity and UX behave across Ethereum DeFi.
ETF access has broadened exposure to ether while DATs aim to connect investors to on‑chain economic activity that ETFs do not capture. Ethereum’s price movements in 2025 reflected these dynamics: ETH fell to $1,472 in April before rebounding to $4,832 by August as DATs trended. For builders and product teams, the emphasis is shifting toward scaling plus practical, bank‑like products that mix self‑custody, yield and composability into user experiences familiar to mainstream users.

Solana’s Preparation for 2026
Solana spent 2025 addressing real‑world pressure: activity peaked early in the year, driven largely by memecoin trading that pushed the network and helped harden it under load. Lucas Bruder, CEO of Jito Labs, said block space increased roughly 25% in 2025, which improved user experience and lowered fees, and that year also attracted a new wave of DeFi teams. Jito doubled down on infrastructure work such as BAM to make transaction sequencing more transparent, aiming for better pricing and applications.
A key technical milestone on Solana is the planned Alpenglow upgrade, expected in 2026. Bruder described it as a simplification of consensus that should materially improve reliability and sharply reduce confirmation times: where finalization today typically takes 12–13 seconds, Alpenglow is expected to cut that toward around one second. That level of finality is framed as a prerequisite for high‑stakes financial activity and for realizing Solana’s vision as a high‑throughput financial network; for related perspectives on tokenization and coexistence between chains, see tokenization and coexistence.
Key takeaways for 2026
Both networks are prioritizing different paths to the same end: more reliable, lower‑cost settlement and better interoperability for DeFi. Ethereum’s trajectory centers on institutional adoption, DATs and layer‑two unification that should simplify user flows and liquidity. Solana’s roadmap focuses on throughput, sequencing improvements like BAM and a consensus simplification via Alpenglow that targets near‑instant finality. Together, these changes could reshape how on‑chain financial products are built and used.
Why this matters
If you run mining or validation hardware, the immediate technical changes here may not require daily action, but they can alter demand patterns you see on‑chain. Greater institutional participation and DATs on Ethereum can shift fee composition and on‑chain activity toward different DeFi primitives, while Solana’s faster finality and higher capacity could attract more high‑frequency financial flows. Understanding these shifts helps you anticipate changes in transaction volumes, fee dynamics and the types of workloads your nodes or rigs handle.
At the same time, improved interoperability and faster finality can change product design and user behaviour without changing basic hardware needs. For small and mid‑scale operators (1–1000 devices), the practical impact will often be operational: uptime expectations, software updates and monitoring requirements may increase as applications demand steadier performance and faster confirmations.
What to do?
- Monitor network announcements and upgrade guides from client teams so you can schedule maintenance and software updates without surprises.
- Track fee and volume trends on the chains you support; institutional flows and new DeFi primitives can change fee patterns that affect revenue or costs.
- Ensure robust monitoring and backups for validators/nodes—faster finality and heavier financial traffic increase the importance of reliable uptime and quick recovery.
- Consider diversifying across services or chains if you provision resources for transaction processing, since different networks may attract different workloads.
- Keep hardware and firmware current and maintain basic security hygiene; infrastructure hardening in the networks increases expectations for operator reliability.
