TL;DR

Blockchain Activity: Ethereum activity rose 16% while fees fell 57%, aided by gas limit and PeerDAS upgrades. Polygon mirrored the trend with an 82% surge in transactions.
Rollups & Avalanche: Arbitrum’s batching design separated execution from calldata costs, stabilizing fees under heavy loads. Avalanche’s growth came from stablecoin payments and institutional settlement.
Declines & Market Context: BNB, Base, HyperEVM, and Solana posted steep declines. Market cap stagnated between $2.9T–$3.1T, limiting volatility and rotation.

Blockchain activity in December painted a striking picture: transactions surged across major networks while fee revenues dropped. Data compiled by Nansen highlighted Ethereum, Polygon, Arbitrum, Avalanche, Bitcoin, Tron, and The Open Network (TON) as ecosystems experiencing higher throughput but lower costs. This divergence signals a structural shift in how blockchains manage demand, with scaling upgrades and rollups expanding capacity without sparking congestion or bidding wars for block space.

Ethereum and Polygon Lead the Divergence

Ethereum transactions rose 16% even as fee revenue fell 57%. The network’s November gas limit increase to 60 million allowed more contract calls per block, while December’s Fusaka upgrade introduced PeerDAS to expand data availability and reduce rollup costs. Polygon mirrored this pattern, with transactions jumping 82% and fees dropping 47%. Its Madhugiri hard fork cut consensus time to one second, boosting throughput by 33% and making gas-heavy operations more efficient.

Rollups and Avalanche’s Ecosystem Growth

Arbitrum showcased the economics of rollup scaling, batching transactions off-chain, and posting compressed data to Ethereum. This design separated execution costs from calldata expenses, dampening fee volatility despite higher loads. Avalanche’s transaction growth stemmed from stablecoin payments, institutional settlements, and consumer platforms, such as ticketing and gaming. These use cases generated high throughput but little competition for blockspace, enabling activity to rise while fees fell.

Blockchains Facing Declines

Not all chains shared the same divergence. BNB Chain saw transactions plunge 79% with fees down 14%. Base contracted sharply, with activity falling 75% and fee revenue dropping 63%. HyperEVM recorded one of the steepest declines, with transactions down 119% and fees falling 46%. Solana, despite being the busiest network with 1.7 billion transactions, posted a 21% month-on-month decrease alongside a 17% drop in fees.

Market Context and Broader Implications

The synchronized declines across some networks aligned with stagnant market conditions. Crypto market capitalization hovered between $2.9 trillion and $3.1 trillion throughout December, limiting volatility and capital rotation. The broader trend suggests that scaling upgrades and ecosystem-specific use cases are reshaping blockchain economics, allowing certain networks to thrive even as fee pressure fades. This structural evolution could redefine how blockchains sustain growth in high-demand environments.
