Hook
In the second quarter of 2025, the average transaction fee on Conflux Network hovered at $0.007. On Ethereum, it remained above $0.45. That 64x gap is not a quirk of market timing—it is a structural bet. Watching the ledger breathe beneath the noise, I see a pattern that echoes Kevin Kelly’s 2026 prophecy about AI: when cost becomes the decisive variable, the open-source, state-backed models will overthrow the premium incumbents. But in blockchain, the ledger does not lie—and the cost advantage comes with a weight that few are willing to measure.
Context
Chinese public blockchains—Conflux, Neo, the BSN Spartan Network, and newer entrants like TreeGraph—have long positioned themselves as the low-cost alternative to Ethereum, Solana, and the rest of the global layer-1 landscape. Their value proposition extends beyond mere throughput. They offer deterministic low fees subsidized by consortium-backed infrastructure, integration with China’s digital yuan ecosystem, and regulatory compliance that foreign chains cannot match. Since 2023, the average gas price on these networks has fallen by 80% in real terms, even as user activity tripled. This is not a spontaneous market outcome; it is a deliberate industrial policy to capture the 90% of global transactions that are price-sensitive: remittances, supply chain attestations, and micropayments in emerging markets.
During my work with the Bank of Thailand on a CBDC interoperability pilot, I observed firsthand how cost efficiency drives inclusion. When a farmer in Isaan can send $5 worth of stablecoins for $0.01 instead of $0.50, the economic behavior shifts. But I also saw the fragility: cheap infrastructure attracts volume, but volume without value can turn into noise. The Chinese chains have built their cost edge on three pillars: delegated Byzantine fault tolerance (d-BFT) that reduces validator count to 25–30, state-sponsored node hosting that eliminates profit margin pressure, and a reluctance to charge full gas for compliance-related transactions. The result is a ledger that breathes cheaply—but does it breathe sustainably?
Core: The Architecture of Cheapness
To understand the cost compression, we must decompose a typical transaction fee. On Ethereum, a simple ERC-20 transfer incurs base fee (burned), priority fee (to validators), and data cost (calldata). In Q2 2025, that sum averaged $0.45. On Conflux, the same operation costs $0.007. The difference is not solely due to congestion. Ethereum’s PoS network has over 1 million validators; Conflux has 25. Each Conflux validator is a consortium member—either a state-owned enterprise or a regulated fintech—running nodes on subsidized cloud infrastructure. They do not demand high priority fees because they are not profit-maximizing; they are serving a national digital strategy.
The economic model is asymmetric. Ethereum validators earn yield from issuance and fees; Conflux validators earn no native token yield—the network does not inflate. Instead, their compensation comes as ecosystem grants, tax benefits, and cross-subsidies from parent corporations. This is not decentralization for the sake of it; it is centralized efficiency disguised as a public chain. The protocol remembers what the user forgets: every low-cost transaction is underwritten by a centralized trust assumption that the consortium will not collude to reorg the ledger.
Further cost savings come from the transaction structure itself. Chinese chains often bundle multiple operations into a single batch, using zero-knowledge proofs at the chain level to compress data. For example, TreeGraph’s aggregated signature scheme reduces the storage footprint of each transaction by 60%, lowering the gas needed for long-term state retention. This is genuine technical innovation—but it is innovation that prioritizes cost over censorship resistance. The ability to batch transactions presumes a level of identity tracking that foreign chains would reject. Volatility is just truth seeking equilibrium: the low cost is a subsidy paid in freedom.
Contrarian: The Decoupling Thesis
The prevailing narrative among crypto natives is that cheap chains will eventually win by attracting liquidity and users away from expensive ones. I challenge this. The decoupling thesis—that cost advantage alone can drive mainstream adoption—ignores the very thing that makes a blockchain valuable: trust in the asset’s sovereignty. When a Chinese public chain offers fees at 1/64th of Ethereum, it is not competing on the same plane. It is offering a different product: a permissioned low-cost settlement layer for regulated use cases, not a global permissionless platform.
Consider the risk: if the consortium behind Conflux were to freeze a wallet or reverse a transaction (which the architecture technically allows under certain judicial orders), the low-cost advantage evaporates for any user seeking finality. The cost savings are a form of rent—a discount for accepting conditional finality. This is the moral hazard of cheap infrastructure. Between the code and the conscience lies the gap that the market often ignores until a crisis. In the 2022 collapse of algorithmic stablecoins, we saw that cheap money attracted leverage, not stability. Similarly, cheap transactions attract volume, but not necessarily value.
Moreover, the cost advantage is not static. Ethereum’s upcoming Danksharding and EIP-4844 implementations aim to reduce layer-2 settlement fees to $0.01 or less by 2027. If that happens, the Chinese chains lose their primary differentiator. They will then need to compete on ecosystem depth, developer tooling, and asset availability—areas where Ethereum and Solana still hold a commanding lead. The question is not whether Chinese chains can be cheap, but whether they can remain cheap while building the trust necessary to retain users once incumbents match their price.
Takeaway
The future of blockchain competition may not be about which chain has the lowest fees, but about which chain can offer the most valuable services per fee. Low cost is a table stake, not a winning hand. For the CBDC researcher watching from Bangkok, the lesson is clear: cost compression is inevitable, but the compression must be accompanied by an expansion of trust. Otherwise we are building a fast highway to a destination no one wants to reach. Watching the ledger breathe beneath the noise, I believe the market will eventually price in the risk of cheap centralization—and that equilibrium will be higher than today’s fees but far more resilient.
