Over the past seven days, the Bitcoin network’s hashrate has stabilized at around 600 exahashes per second, a quiet plateau after the fourth halving’s seismic reduction in block subsidy. But the revenue for miners in BTC terms has dropped by 50% since the April 2024 event. The price of the asset has risen to compensate, yet the structural tension remains invisible to most observers. Meanwhile, the three largest mining pools—F2Pool, AntPool, and ViaBTC—now command over 70% of the network’s computational power. This is not news; it is a repeating pattern. But what disturbs me is the collective silence about what this means for the core promise of decentralization. We chart the code, but the soul chooses the path.
To understand the hollowing of the Bitcoin dream, we must step back into the philosophical foundations that drew me into this space. In 2017, I was living in Mexico City, watching the ICO circus unfold. Most people were chasing tokens with no technical merit. I found refuge in the Ethereum Classic community, translating white papers about immutability into Spanish for newcomers. That period grounded my conviction that decentralization is not a feature to be optimized for efficiency; it is a moral stance against centralized control. The “Code is Law” doctrine felt pure. Today, the code still executes, but the economic laws have reshaped the terrain. The halving is supposed to be a deflationary event that rewards long-term hodlers, but it also accelerates the centralization of mining capital. The cost of a single ASIC rig now exceeds $10,000, and the scale required for profitability pushes out hobbyists. Hash power concentrates. The network’s security becomes dependent on a few large entities that could be co-opted by regulators or coerced by states. This is not a conspiracy theory; it is a mathematical inevitability when the cost of production rises faster than the revenue per unit. The soul of the network—its permissionless nature—begins to atrophy.
My own research during the 2022 bear market hardened this skepticism. I spent six months auditing the consensus mechanisms of failing L1 protocols, identifying three critical centralization vulnerabilities in their validator sets. One of those protocols had a governance token that allowed a single whale to dictate network upgrades. The lesson was clear: decentralization is never a binary state; it is a fragile equilibrium that must be actively maintained. The same principle applies to Bitcoin mining. The proof-of-work algorithm is elegant, but the industrial scale of modern mining operations renders the original vision of one-CPU-one-vote obsolete. The halving simply accelerates this trend. We chart the code, but the soul chooses the path—and the path of least resistance leads to oligopoly.
The core insight is this: the halving does not strengthen Bitcoin’s decentralization; it weakens it under the guise of scarcity. The narrative of digital gold obscures the fact that gold mining itself is subject to concentration—but gold does not pretend to be a decentralized system of peer-to-peer cash. Bitcoin does. The dissonance between the promise and the reality is not just philosophical; it has practical consequences. A mining cartel of three pools could, in theory, collude to deny service to certain transactions or even reorganize the chain. The risk is small today because of the economic incentive to maintain trust, but the structural vulnerability grows with each halving cycle. The market’s current optimism about the halving’s price impact conveniently ignores this long-term erosion of network resilience. We are trading sovereignty for efficiency, and calling it progress.
Let me pivot to Ethereum’s Layer2 ecosystem, where the same pattern repeats with even less transparency. Almost every popular rollup today operates with a centralized sequencer. Optimism’s sequencer is a single entity; Arbitrum’s is controlled by Offchain Labs; Base is run by Coinbase. These sequencers determine the order of transactions, can censor or front-run users, and are the sole arbiters of state updates. The “decentralized sequencing” roadmap has been a PowerPoint slide for over two years. I know this because I participated in MakerDAO’s governance forums during DeFi Summer in 2020, where I published a critique of DAI’s over-collateralization risks. That experience taught me that pseudonymous trust is brittle. The same illogical optimism that drove people to ignore DAI’s oracle fragility now drives them to accept centralized sequencers because the user experience is smooth and gas fees are low. But when the bull market fades and the pressure mounts, these sequencers become single points of failure. In a bear market, the first thing to break is the promise of trustlessness when it is not enforced by code. And the code does not enforce decentralization of sequencing. The contract executes, but the conscience judges—and if the conscience is a corporate entity, the judgment will align with shareholder value, not network sovereignty.
This brings me to the stablecoin sector, where the same maturity mismatch and stacked risk are masked by the bull market’s rising tide. Take Ethena’s sUSDe, which offers a yield of over 20% by executing an arbitrage strategy on funding rates. The yield is real when markets are trending up and perpetual swaps are in contango. But in a sharp downturn, funding rates flip negative, and the strategy loses money. The protocol then relies on its reserve fund to cover the gap—until that fund is exhausted. The risk is not just credit; it is liquidity and maturity mismatch, the same rot that killed Terra. I saw this pattern before: in 2021, when I collaborated with a small group of artists to launch a Soul-Bound Token project for preserving indigenous Mexican heritage, I learned the hard way that any system built on continuous growth assumptions will crack when growth stops. The NFT project attracted 2,000 wallets, but the community’s trust was tied to the market’s enthusiasm. When the bear came, the project remained alive because it had a real purpose—cultural memory—not because it was economically sustainable. sUSDe has no such purpose. It is a financial instrument that depends on the continued presence of market participants willing to pay high funding rates. That willingness disappears in a crash. And when it does, the protocol’s design ensures that the largest holders—the whales—can exit first, leaving smaller participants with the losses. The code executes evenhandedly, but the economic dynamics are not evenhanded. The soul of the stablecoin—its peg—becomes a memory.
Now the contrarian angle. Some will argue that users do not care about decentralization. They vote with their feet: Base, a fully centralized rollup, has billions in total value locked. The market has spoken, and it prefers speed and low fees over sovereignty. Perhaps the idealistic vision of a peer-to-peer electronic cash system was always a luxury for a few cypherpunks, not a product for the masses. Perhaps the path forward is a hybrid: centralized user experience with decentralized settlement, akin to how your bank account is centralized but the dollar is decentralized across many institutions. But this pragmatic view ignores the systemic risk that builds up when the entire infrastructure depends on a few sequencers and mining pools. If a sequencer goes down or is attacked, the entire rollup halts. If a mining pool colludes with a state, the Bitcoin chain can be censored. The users may not care today, but they will care when the cost is their wealth. The history of finance is a history of regulators shutting down unregulated payment systems. Ethereum Classic taught me that immutability is a myth without a diverse and distributed validator set. The same applies to Bitcoin. The difference is that Bitcoin has a more robust incentive model—but that model is being eroded by scale. The contrarian silence on this issue is deafening.
I recall my experience in 2026, when I joined a DAO focused on ethical AI governance. I wrote a manifesto on “Sovereign Data Rights” that was cited by regulators in the EU and Latin America. That work confirmed my belief that technology can empower individual agency only if its architecture is designed for that purpose. The architecture of Bitcoin, Layer2s, and stablecoins is increasingly designed for efficiency, not agency. The choices we make now—to accept centralized sequencers, to ignore mining pool concentration, to embrace synthetic yield products—are choices that define the soul of the network. We chart the code, but the soul chooses the path. And the path we are choosing is one of convenience over resilience.
So where does this leave us? I am not proposing that we abandon these technologies. Bitcoin is still the most censorship-resistant store of value we have. Layer2s offer usability that base layers cannot. Stablecoins provide a crucial on-ramp for unbanked populations. But we must stop pretending that decentralization is a property that we can assume without active maintenance. Every halving, every new sequencer, every yield-farming product should be examined for its effect on concentration of power. We need metrics for decentralization—like Nakamoto coefficient, entropy of hash distribution, sequencer fault tolerance—and we need to hold projects accountable when those metrics degrade.
The question that haunts me is this: as the blocks tick by and the hash increases, are we building a network of sovereign peers, or merely a faster, cheaper version of the old world? The code can be rewritten, but the path is already chosen. We chart the code, but the soul chooses the path. And I fear the soul of this industry is being traded for the illusion of progress.
