Value Accrual Mechanisms
Blockchain protocols rely on several key mechanisms to accrue value and incentivize network security. As highlighted by cryptocurrency analyst Toghrul Maharram, these typically include:
Transaction fees form a crucial component of this value accrual system. They can be further broken down into:
- Base fees: Paid to ensure transaction inclusion in the canonical chain
- Priority fees: Paid during periods of congestion or for time-sensitive transactions
As blockchain capacity increases, protocols face a strategic dilemma: should they restrict capacity to maximize per-transaction value through priority fees, or expand capacity to increase overall transaction volume?
MEV and Protocol Revenue
Miner Extractable Value (MEV) has emerged as a significant source of protocol revenue. The impact of MEV varies across different blockchains. For instance, Solana accrues a higher percentage of its total protocol revenue through MEV compared to Ethereum.
Common MEV strategies include:
- Backruns (e.g., CEX-DEX or DEX-DEX arbitrage)
- Frontruns
- Frontrun-backrun bundles (“sandwich attacks”)
- Liquidations
While some forms of MEV contribute to capital efficiency, others can be considered malicious. Validators often collaborate with specialized entities to optimize MEV extraction, sharing profits to ensure the inclusion of MEV-generating transactions.
Appchains and Application-Specific Sequencing
As protocols grapple with value accrual, applications are seeking ways to capture more of the revenue generated by their activities. This has led to the rise of two key concepts:
- Appchains: Physically separate application states to internalize fees and MEV
- Application-Specific Sequencing (ASS): Allows applications to capture fees and MEV while maintaining composability
These approaches aim to shift value accrual from the underlying protocol to the applications themselves, challenging the traditional “fat protocol” thesis.
Token Emissions and Inflation
Token emissions present a delicate balance for protocols. While necessary for incentivizing network security, they impose a “tax” on non-staked token holders through dilution. Protocols must optimize emission rates to maintain security without overly burdening token holders.
Ethereum and Solana have implemented fee-burning mechanisms to address this issue:
- Ethereum (post-EIP-1559): Burns the base fee of every transaction
- Solana: Burns half of both the base fee and priority fee
These mechanisms aim to offset token emissions and potentially create deflationary pressure. However, as capacity increases and applications explore alternative value capture methods, protocols may need to shift their focus from maximizing scarcity to minimizing inflation.
The Future of Fat Protocols
The “fat protocol” thesis, which posited that value would accrue primarily to the protocol layer rather than applications, is facing challenges. As Maharram notes:
Ultimately, the endgame for most protocols converges. Despite varying current approaches, the misalignment of incentives between protocols and the applications built atop them will shift value accrual toward the applications themselves.
This shift suggests that underlying protocols may need to adapt their strategies, focusing on accruing value through sheer transaction volume rather than maximizing the value of individual transactions.
Key Takeaways
- Blockchain protocols face a strategic dilemma between restricting capacity for higher fees and expanding capacity for increased volume.
- MEV has become a significant source of protocol revenue, with varying impacts across different blockchains.
- Appchains and Application-Specific Sequencing are challenging traditional value accrual models, shifting revenue towards applications.
- Token emission strategies are evolving, with a potential shift from maximizing scarcity to minimizing inflation.
- The “fat protocol” thesis is being challenged, suggesting a need for protocols to adapt their value accrual strategies.
Conclusion
The blockchain ecosystem is at a crossroads, with protocols facing unprecedented challenges in maintaining value accrual and relevance. As applications seek greater control over their revenue streams and capacity continues to expand, protocols must innovate to remain competitive. The future may see a more balanced distribution of value between protocols and applications, requiring a rethinking of traditional blockchain economics. How will your favorite blockchain adapt to these changing dynamics?
