One Month Into 2026: Ethereum Tunes Scaling, BNB Goes Sub-Second, And Avalanche Tokenizes Credit

Hard to believe, but we’re already through the first month of 2026 — and the blockchain world clearly didn’t wait around for the dust to settle. It’s only January, and already we’ve seen protocol upgrades, new scaling approaches, and serious momentum on the institutional front. So, let’s take a closer look at what’s stood out so far, throwing in some of our editorial perspective along the way.

Ethereum – Scaling Without the Drama

Ethereum began the year with a quiet but strategic move: increasing the number of data blobs per block as part of its second Blob Parameter Offset (BPO) adjustment. This change, while technical and low-key, is foundational. It builds on December’s Fusaka upgrade, which introduced the initial blob space for rollups and helped drive gas fees down. 

By raising the blob target from 10 to 14 (and the maximum from 15 to 21), Ethereum is doubling down on its commitment to efficient data availability for Layer 2s. This isn’t a flashy, name-brand fork, but it’s arguably just as important: it improves how Ethereum supports rollups like Optimism, Arbitrum, and zkSync without compromising the base layer’s security or decentralization. The upgrade exemplifies Ethereum’s new rhythm — more like infrastructure refinement than dramatic reinvention.

Bitcoin – Torn Between Caution and the Future

Bitcoin’s conservatism was on full display this month. The proposed BIP-110 soft fork, intended to limit spammy OP_RETURN data in transactions, gained almost no traction — only around 3% of nodes signaled support. 

It’s a clear reminder that change in Bitcoin land moves at glacial speed, no matter how justified. Yet interestingly, while the mainnet stagnates on the surface, some developers are already preparing for the next cryptographic paradigm.

A team from BTQ launched a quantum-safe testnet dubbed “Bitcoin Quantum,” replacing Bitcoin’s standard ECDSA with ML-DSA, a NIST-backed quantum-resistant algorithm. Though purely experimental, it serves as a warning shot: Bitcoin’s current security model won’t last forever. The main protocol may be slow to move, but the community’s curiosity remains very much alive.

Polkadot – Giving In to EVM Gravity

January saw Polkadot embrace EVM tooling more fully, allowing developers to use familiar Ethereum stacks while building on its parachains. The network also rolled out latency improvements, bringing transaction speeds closer to real-time. 

For years, Polkadot tried to chart its own course with Substrate and ink! — its custom smart contract language — but struggled to gain mass adoption among developers already fluent in Solidity. This pivot feels less like surrender and more like smart diplomacy: by supporting Ethereum’s tools and workflows, Polkadot becomes a more inviting home for builders who might otherwise stick with L2s. It’s a strategic recalibration that could help grow its developer ecosystem faster in 2026.

Cardano – Subtle, But Strategic

Cardano’s upcoming hard fork, Protocol V11 (“van Rossem”), isn’t introducing massive new features, but it is tightening the bolts where it matters. The upgrade includes stricter validation rules, unique VRF enforcement to prevent certain types of stake-based exploits, and refined Plutus scripting primitives. These enhancements are aimed at making the network more predictable and developer-friendly. 

Importantly, it also signals a shift in governance maturity: the community voted on the fork’s direction, showing a healthy, engaged DRep system in action. For Cardano, the focus remains clear — build gradually, with emphasis on auditability and formal assurance. It’s not going to win speed races, but it may well win trust.

BNB Chain – Fermi Fork Brings the Speed

On January 14, 2026, BNB Chain executed its long-planned Fermi hard fork — an upgrade that pushed its block times down to an all-time low of 0.45 seconds. Rolled out via client v1.6.4, this milestone marks the third and final phase of the network’s roadmap for accelerated block production. The fork implements key Binance Evolution Proposals like BEP-619, which shortens block intervals, and BEP-590, which strengthens finality guarantees.

While the numbers are technical, the impact is immediately tangible. Transactions now confirm faster, and latency-sensitive dApps — particularly in DeFi and trading — benefit from noticeably quicker interactions. Crucially, Fermi doesn’t sacrifice network reliability to achieve this. Binance has positioned the fork as part of a larger vision: a high-speed, low-latency chain that doesn’t trade performance for stability. It’s another reminder that BNB Chain is laser-focused on user experience, even if it continues to raise eyebrows on the decentralization front.

Avalanche – Institutional DeFi Grows Up

While Avalanche didn’t push any protocol-level upgrades in January, it made headlines in a different arena: institutional finance. On January 15, 2026, the network hosted the launch of Galaxy CLO 2025-1 — its first-ever tokenized collateralized loan obligation. The $75 million structured credit product includes a hefty $50 million tranche from Grove, a credit protocol operating within Avalanche’s Sky Ecosystem.

This isn’t just another DeFi novelty — it’s a serious step toward bringing real-world financial instruments on-chain. By handling a complex, regulated asset like a CLO, Avalanche is proving its Layer 1 infrastructure, especially its subnet model, can handle more than just yield farms and NFTs. It’s a quiet but powerful signal to institutional players: Avalanche is ready to support the next generation of tokenized finance.

TRON – Plugging into the Broader Wallet World

TRON kicked off 2026 by significantly expanding its ecosystem’s reach. On January 21, WalletConnect added native support for the TRON network — instantly linking over 600 wallets and 70,000 dApps to TRON’s DeFi and NFT infrastructure. With this move, users of popular wallets like Trust Wallet and Binance Wallet can now interact directly with TRON-based applications and execute TRC-20 stablecoin transactions without friction.

Given TRON’s dominant position in the stablecoin space — especially with its massive USDT volumes — this integration isn’t just a technical upgrade, it’s a strategic leap in accessibility. For developers, it means broader user access. For users, it means TRON is no longer a walled garden. The network continues to blur the line between centralized efficiency and decentralized interoperability, and this WalletConnect move is a prime example of that balancing act.

Optimism – Turning Revenue Into Utility

Optimism kicked off the year with a two-pronged push: one part governance, one part developer UX. On the governance side, the Optimism Foundation proposed a bold tokenomics shift — using 50% of Superchain revenue to buy back OP tokens on the open market. That revenue comes from sequencer fees across all OP Stack chains, effectively linking OP’s value to real network usage. The DAO vote went live on January 22, and if passed, monthly buybacks could start as early as February. It’s a direct, market-driven way to reinforce OP’s role in the broader ecosystem.

Meanwhile, on the builder front, Optimism released Actions, a new open-source TypeScript SDK that drastically simplifies DeFi integration. Instead of writing complex on-chain logic from scratch, developers can now plug into common DeFi operations — like swaps, loans, and payments — with just a few lines of code. The SDK comes with wallet support baked in and works across chains in the OP Stack by default. Together, the buyback proposal and the Actions SDK show Optimism’s evolving focus: reward participation, reduce friction, and accelerate composability across its Superchain vision.
