Blockchain decentralization fragments monetary landscape, undermining network effects

Money functions as a coordination device, underpinned by strong network effects where greater acceptance reinforces greater use.

While public permissionless blockchains aim to replicate this coordination without a central authority, their decentralized consensus mechanisms introduce a fundamental tension.

Validators, who maintain the blockchain, require rewards that ultimately translate into congestion rents for users through transaction fees.

These capacity constraints are a necessary feature to incentivize validators, especially for chains with stringent consensus standards.

However, high fees deter users, pushing them to alternative blockchains with lower coordination thresholds and, consequently, less security.

This user migration and splintering across platforms directly undercuts the very network effects that give money its social value, leading to fragmentation rather than convergence.

The phenomenon of fragmentation is evident in the evolution of Layer 1 blockchains and stablecoins.

High gas fees on networks like Ethereum, particularly during periods of peak activity such as DeFi surges or NFT minting, have made routine transactions prohibitively expensive.

This has prompted users to migrate to competing chains like Solana, Tron, and BNB Chain, which offer lower fees and higher throughput.

By late 2025, these alternative chains generated comparable fee revenue, demonstrating a fragmented landscape where no single platform dominates all use cases.

Stablecoins, too, inherit this fragmentation, existing in non-interoperable forms across different blockchains.

Transferring stablecoins between chains requires risky and costly bridges, undermining the fungibility and seamless transferability essential for a robust payment instrument.
