Editor's Note: L2 has a cost advantage over L1 in terms of operation cost, as L2 only needs to pay the cost of a single sequencer, while L1 needs to pay for the security of all validators. L2 has unique advantages in speed and reducing MEV, and can support dApp revenue maximization through innovative economic models. Although L2 cannot compete with L1 in terms of liquidity, its potential in the dApp economy will drive the crypto industry's transition from infrastructure to profit-driven long-term business models.

The following is the original content (slightly reorganized for clarity):

Here is a decision matrix from the dApp perspective, analyzing the choice to deploy on L1 or L2 in the current environment, assuming both support similar types of applications (i.e., L1/L2 are not customized for specific application types).

Other than relatively less MEV (Miner Extractable Value) due to the centralization of block producers, L2 has not fully utilized its other advantages. For instance, while L2 has the potential for lower transaction costs and higher throughput, Solana currently leads in performance and transaction costs compared to L2 in the EVM ecosystem.

As Solana continues to improve throughput and advance MEV capture mechanisms (such as ASS and MCP), L2 needs to explore new ways to help dApps maximize revenue and reduce costs. In my current view, L2 is structurally more advantageous than L1 and can execute dApp revenue maximization strategies more quickly.

One of the key roles of the execution layer in maximizing application revenue is the allocation of fees/MEV.

Currently, achieving MEV capture or fee sharing relies on "honest block proposers," who are willing to follow ordering rules of precedence, or proposers who share revenue with the application according to preset rules. Another approach is to allocate a portion of the base fee from EIP1559 to user-interacting dApps, which Canto CSR and EVMOS seem to adopt. This can at least enable dApps to enhance their ability to bid on their own MEV revenue, making them more competitive in the transaction inclusion market.

In the L2 ecosystem, if the block proposer is operated by a team (i.e., a single block proposer), then it is inherently "honest" and can ensure the transparency of the block construction algorithm through a reputation mechanism or TEE (Trusted Execution Environment) technology. Currently, two L2s have adopted fee splitting and priority ordering for block construction, and the Flashbots Builder can also provide similar functionality to the OP-Stack ecosystem with minor modifications.

In the SVM (Solana Virtual Machine) ecosystem, similar infrastructure like Jito can proportionally reallocate MEV revenue to dApps (such as calculated by CUs, similar to the mechanism adopted by Blast).

This means that while L1 is still researching MCP and built-in ASS schemes (Solana may advance this effort, but there is no equivalent CSR revival plan in the EVM ecosystem), L2s can implement these features more quickly. Since L2s can rely on trusted block producers or TEE technology without the need to adopt the OCAproof mechanism mandatorily, they can more quickly adjust a dApp's MRMC (revenue, cost, MEV competition) model.

However, the advantages of L2s are not only in development speed or fee reallocation capabilities; they also face fewer structural constraints.

The survival conditions of the L1 ecosystem (i.e., the conditions to maintain the validator network) can be described by the following equation: Total Validators × Validator Operating Cost + Staking Capital Requirement × Capital Cost < TEV (Inflation + Total Network Fee + MEV Tip)

From the perspective of a single validator: Validator Operating Cost + Staking Capital Requirement × Capital Cost > Inflation Reward + Transaction Fees + MEV Revenue

In other words, L1 faces a hard constraint to reduce inflation or decrease fees (through sharing with dApps)—validators must remain profitable!

If the Validator Operating Cost is high, this constraint becomes more apparent. For example, Helius pointed out in a related article to SIMD228 that if inflation is reduced according to the proposed issuance curve, at a 70% staking rate, 3.4% of current validators may drop out due to declining profitability (assuming REV maintains 2024 levels of volatility).

REV (MEV share in staking rewards) experiences extreme volatility:· On the day of the TRUMP event, the REV share reached 66%· On November 19, 2024, the REV share was 50%· Currently (at the time of writing), the REV share is only 14.4%

This means that in the L1 ecosystem, due to validator profit pressure, reducing inflation or adjusting fee distribution has a ceiling, while L2 is not bound by this constraint and can therefore more freely explore strategies to optimize dApp revenue.

Solana validators currently face high operating costs, directly limiting the "shareable profit space," especially as the inflation rate decreases. If Solana validators must rely on REV (MEV share in staking rewards) to remain profitable, then the total proportion that can be allocated to the dApp will be strictly limited.

This brings an interesting trade-off: the higher the validator operating costs, the higher the network's overall fee take-rate must be.

From the perspective of the entire network, the following formula must be met: Total Network Operating Costs (including capital costs) < Total Network REV + Circulating Supply

Ethereum faces a similar situation, but to a lesser extent. Currently, the APR (Annual Percentage Rate) of ETH staking ranges from 2.9% to 3.6%, with approximately 20% coming from REV. This also means that Ethereum's ability to optimize dApp revenue is similarly constrained by validator profit requirements.

This is where L2 has a natural advantage. On L2, the total network operating cost is only the operating cost of a sequencer, with no capital costs because there is no staking requirement.

Compared to L1 with a large number of validators, the profit margin required to maintain a break-even on L2 is minimal. This means that while maintaining the same profit margin, L2 can allocate more value to the dApp ecosystem, significantly increasing the dApp's revenue potential.

The network cost of L2 will always be lower than an equivalent-sized L1 because L2 only needs to periodically "borrow" the security of L1 (occupying part of L1's block space), while L1 must bear the full cost of securing its entire block space.

L1 vs L2 Battle: Who Can Dominate the dApp Economy?

By definition, L2 cannot compete with L1 in terms of liquidity, and since the user base still primarily resides on L1, L2 has also struggled to directly challenge L1 at the user level (although Base is changing this trend).

However, to date, few L2 solutions have truly leveraged their unique advantages as L2—those characteristics derived from the centralization of block production.

Superficially, the most discussed benefits of L2 are:
1. Mitigating malicious MEV
2. Increasing transaction throughput (some L2 solutions are exploring this direction)

But more importantly, the next main battleground in the L1 vs. L2 war will be the dApp economic model.

Advantage of L2: Non-OCAproof TFM (Non-Orthogonal Composability TFM)

Advantage of L1: CSR (Contract Self-Revenue) or MCP (Minimal Consensus Protocol) + MEV Tax

This competition is the most bullish thing for the crypto industry

Because it directly brings:
· dApp revenue maximization, cost minimization, thereby incentivizing developers to build better dApps.

· Changing the incentive structure of the crypto industry from the previous infrastructure token premium (L(x) premium) to a profit-driven long-term crypto business.

· Combining DeFi regulatory clarity, protocol-level token value capture, and institutional capital inflow, driving the crypto market into an era centered on "actual business models."

Just as in the past few years we have seen funds flowing into infrastructure development, driving innovation in areas such as applied cryptography, performance engineering, consensus mechanisms, etc., today, inter-chain competition will bring about a significant transformation in industry incentive structures and attract the smartest talent to Crypto application layers.

Now is truly the starting point for the large-scale adoption of crypto!
