The $100 Trillion Shift — Part 3: The Infrastructure Layer
The Problem No ETF Can Solve
Part 2 of this series documented the first wave of institutional capital flowing into Bitcoin: more than $100 billion in U.S. spot Bitcoin ETFs — reaching more than $115 billion at peak — alongside sovereign wealth fund positions in Abu Dhabi and Norway, and corporate treasury strategies pioneered by Strategy and replicated by dozens of companies worldwide.
But it closed with an observation that deserves to be the starting point for Part 3.
Institutional investors often require yield alongside price appreciation. A pension fund that allocates to Bitcoin through BlackRock's IBIT holds Bitcoin that does nothing while it waits. It does not earn interest. It does not generate income. It appreciates — or depreciates — with Bitcoin's price, and nothing else. Bitcoin's lack of native yield limits its addressable institutional market — restricting allocation to the subset of mandates that permit pure price-appreciation assets, while leaving out the much larger universe of institutions that require income generation alongside capital preservation.
This is not a minor inconvenience. It is a structural problem — and it is the problem that a new category of infrastructure is being built to solve.
Consider how other major asset classes work for institutional investors. Bonds pay coupons. Equities pay dividends. Real estate generates rental income. For pension funds and insurance companies whose mandates require income alongside capital preservation, a pure price-appreciation asset is a harder allocation to justify than one that produces cash flows.
Now consider the scale of what is already staked in other blockchain networks. Approximately 28% of all Ethereum — worth tens of billions of dollars — is currently staked, generating yield for its holders. Approximately 65% of all Solana is staked. For these asset classes, yield is not an optional feature. It is a fundamental characteristic that makes them more attractive to institutional allocators who need income alongside appreciation.
Bitcoin has no native staking mechanism. No yield. No income. It holds. And then it waits.

Matt Hougan, Chief Investment Officer of Bitwise Asset Management, framed the opportunity directly: "Everything aligns for Bitcoin staking being a significant market. There's a lot of demand for Bitcoin yield. Even if you're getting a 3% yield, it's attractive compared to other options."

The infrastructure described in this article represents the industry's collective attempt to answer that demand. It is not one protocol or one approach. It is a category — Bitcoin Finance, or BTCfi — with multiple competing philosophies about how to make Bitcoin productive without sacrificing what makes Bitcoin valuable.
What Bitcoin Yield Actually Requires
Before examining what has been built, it is worth being precise about what the problem actually requires — because the history of BTCfi is, in significant part, a history of approaches that solved some of the problem while creating new versions of others.
Institutional investors who want yield on Bitcoin are not asking for something simple. They are asking for something that satisfies four specific requirements simultaneously.
First: the yield must be real. Not governance tokens distributed at artificial rates to attract capital. Not emissions that dilute the value of the underlying asset. Yield that comes from actual economic activity — from fees generated by real transactions, from interest paid by real borrowers, from staking rewards generated by a protocol that is actually being used.
Second: the Bitcoin must not leave institutional-grade custody. An institution that bridges Bitcoin to another chain, wraps it in a synthetic token, and deposits it in a smart contract has not held Bitcoin through that process. It has held a derivative of Bitcoin managed by a series of intermediaries, each of which introduces new counterparty risk. For fiduciaries, that is not an acceptable arrangement.
Third: the yield must be denominated in Bitcoin or its equivalent. Yield paid in a protocol's governance token creates a secondary asset that the institution must manage, liquidate, or hold — creating operational complexity and additional risk exposure that most institutional frameworks are not designed to absorb.
Fourth: the arrangement must be composable. The Bitcoin generating yield must remain usable as collateral, redeemable at any time, and adjustable as portfolio needs change.
These four requirements define the standard that the BTCfi infrastructure layer must meet. Most of what has been attempted has met one or two of these requirements. Meeting all four simultaneously is the challenge that has defined — and continues to define — the frontier of Bitcoin financial infrastructure.
What Was Tried — and Why Most of It Failed
BTCfi has evolved through multiple approaches, many of which failed due to unsustainable incentives. That history is instructive — it explains why the protocols that remain standing in 2026 are built differently from those that did not survive.
Wrapped Bitcoin — WBTC — was the first large-scale attempt to bring Bitcoin into the Ethereum DeFi ecosystem. By depositing Bitcoin with a custodian and receiving an ERC-20 token in return, holders could participate in Ethereum-based lending and yield protocols. At its peak, WBTC represented approximately $14 billion in bridged Bitcoin. The problem was the custody model: WBTC depended on a centralized custodian whose reliability became a point of concentrated risk — exactly the kind of single point of failure that institutional risk management requires to eliminate.
The broader BTCfi boom of 2024–2025 produced numerous Bitcoin Layer 2 protocols and sidechain-based systems. By 2026, the total value locked in Bitcoin sidechains and Layer 2 networks had declined by approximately 74% from peak levels. Protocols that had used unsustainable token emissions to attract capital discovered that the capital left when the emissions slowed.
📌 Source: Spark Research — "BTCFi in 2026: Why Bitcoin DeFi TVL Shrank 74% and What Comes Next" (2026)
The lesson is consistent: yield infrastructure built on token emissions rather than protocol revenue does not produce durable results. Capital attracted by subsidized yields is not conviction capital. It is mercenary capital that leaves for the next subsidy the moment a better one appears.
The infrastructure that survives this contraction is built differently. Babylon and Core DAO represent two distinct architectural approaches to Bitcoin yield generation — and together, they define the most significant responses to the BTCfi challenge that have emerged from this period of consolidation.
The Two Philosophies: How Babylon and Core DAO Approach Bitcoin Yield
Babylon and Core DAO are both non-custodial Bitcoin staking protocols. Both allow Bitcoin holders to lock their Bitcoin in time-lock transactions on the Bitcoin blockchain without moving it to another chain. Both have attracted significant attention from the institutional and developer communities as potential answers to the Bitcoin yield problem.
But their underlying philosophies — and therefore their architectures, use cases, and limitations — are fundamentally different.
Babylon: Bitcoin as Security Provider
Babylon's design philosophy is that Bitcoin's security — the most battle-tested proof-of-work security model in existence — should be available to other blockchain networks that need it. Proof-of-stake chains face a specific vulnerability: their security depends on the value of their own native tokens, which can be manipulated or depleted in an attack. Babylon proposes to supplement or replace that native token security with Bitcoin security.
The mechanism works through Bitcoin's native scripting capabilities. A Bitcoin holder locks their Bitcoin in a time-lock transaction and delegates that security commitment to a PoS chain of their choice. If the validator on that PoS chain misbehaves, the Bitcoin timelock can be slashed — penalizing the misbehavior with real economic cost. In return, Bitcoin holders receive staking rewards denominated in the native tokens of the PoS chains they are securing. The Bitcoin never leaves the Bitcoin blockchain.
📌 Source: Babylon — "Bitcoin Staking: Unlocking 21M Bitcoins to Secure the Decentralized Economy" (babylonchain.io)
Babylon's approach passes the custody integrity requirement: Bitcoin stays on the Bitcoin blockchain. Where it faces challenges is in the yield denomination requirement — rewards come in the tokens of various PoS chains, which creates the secondary asset management complexity that institutional investors prefer to avoid. It also has no native DeFi ecosystem: Babylon itself does not provide lending, borrowing, or spending functionality.
Core DAO: Bitcoin as Foundation for a Complete Financial Ecosystem
Core DAO's design philosophy is different. Rather than using Bitcoin to secure other chains, Core builds a complete financial ecosystem — with smart contracts, DeFi applications, lending, and spending infrastructure — directly on top of Bitcoin's security model.
Core's consensus mechanism, Satoshi Plus, combines three elements: delegated proof of work (Bitcoin miners delegate hash rate to secure Core's network), delegated proof of stake (CORE token holders stake to participate in validation), and non-custodial Bitcoin staking (Bitcoin holders lock their Bitcoin in time-lock transactions without moving it from the Bitcoin blockchain).
The non-custodial staking is structurally similar to Babylon's — the Bitcoin stays on the Bitcoin blockchain, locked in a native Bitcoin time-lock. What is different is what the staked Bitcoin secures and what it receives in return. Babylon's staked Bitcoin secures third-party PoS chains. Core's staked Bitcoin secures Core's own network — which provides the infrastructure for a full DeFi ecosystem, lending protocols, and consumer applications built directly on top of Bitcoin's security foundation.
📌 Source: Core DAO — "Satoshi Plus Consensus" (docs.coredao.org)
In return for staking, Bitcoin holders receive yield from Core's protocol revenue — fees generated by actual economic activity on the Core network, not from emissions or token inflation. As of June 21, 2026, Core's non-custodial Bitcoin staking has 2,472 Bitcoin locked in time-lock transactions, with 306,742,901 CORE tokens simultaneously staked through the dual staking mechanism.

The comparison is not about which protocol is superior in an absolute sense. They are solving different problems. Babylon is infrastructure for the blockchain security market. Core DAO is infrastructure for the Bitcoin financial services market. The distinction matters for institutional allocators deciding which type of yield infrastructure is relevant to their specific portfolio construction needs.
What the Data Cannot Fully Explain
Examining the participation data for Core DAO raises questions that purely economic analysis does not fully answer — and those questions are worth examining carefully, because they may indicate something significant about the network's trajectory.
The first question concerns the participation of large-scale institutional validators. Global enterprises typically prefer to avoid becoming "one of many" participants in open blockchain networks, where their participation implicitly endorses a specific protocol and creates reputational exposure if the protocol underperforms or attracts regulatory scrutiny. The calculus of corporate risk management generally argues against visible participation in blockchain validation unless the expected return and strategic value clearly justify it. Yet Core DAO has attracted validator participation from entities whose institutional profile would typically argue for caution. Industry observers have noted this as a data point worth tracking, without drawing premature conclusions about what it signifies.
The second question concerns Bitcoin mining hash rate delegation. Core's Satoshi Plus consensus allows Bitcoin miners to delegate hash rate to Core's network without redirecting it from Bitcoin — a technically non-exclusive commitment that costs miners nothing additional if their hardware is already operating. Pure economic logic would predict modest, opportunistic participation: miners who delegate when it requires no effort, and who do not delegate if any friction is involved.
The observed reality — consistently between 85% and 96% of global Bitcoin mining hash rate delegated to Core, peaking at 96.4% in March 2025 — is not fully explained by that economic logic alone. At near-maximum participation rates, there is insufficient variance in the data to attribute the result to pure rational self-interest. The precise drivers of this participation level remain open to interpretation and warrant continued observation.

The Institutional Bridge: lstBTC
For the institutional capital described in Parts 1 and 2, the infrastructure most directly relevant is not the retail staking mechanism but the institutional product built on top of it.
lstBTC — Liquid Staked Bitcoin — is Core's institutional product. It represents Bitcoin plus accrued yield, held with established custodians — BitGo, Copper, and Hex Trust — that are already trusted by regulated institutions worldwide for digital asset management. The Bitcoin does not leave these custodians. In exchange, institutions receive lstBTC: a token that tracks their staked Bitcoin, continues to earn yield, and remains fully tradable, transferable, and usable as collateral.
Behind the scenes, the yield generation strategy runs through Core's dual staking mechanism. Bitcoin serves as collateral. Stablecoins are borrowed against it to acquire CORE tokens. Both Bitcoin and CORE are staked to access the highest yield tier. Rewards — denominated in Bitcoin-equivalent value — flow to lstBTC holders. The CORE price exposure from this strategy is hedged to protect the Bitcoin collateral.
📌 Source: Core DAO — "Liquid Staked Bitcoin (lstBTC): Earn Yield on Bitcoin Collateral" (coredao.org)
The product is designed to address the four requirements identified earlier: yield from actual protocol revenue, Bitcoin remaining in trusted institutional custody, returns denominated in Bitcoin-equivalent value, and full liquidity and composability. Redemption returns the original Bitcoin plus accrued yield directly into custodial accounts, without bridges, exit fees, or complex unwinding procedures.
Major custodians including Fireblocks, Cobo, and Ceffu have integrated Core's infrastructure, providing compliance-ready access within the operational frameworks institutional investors already use.
📌 Source: Core DAO — "Core: The Bitcoin Everything Chain" (coredao.org)
The Consumer Bridge: SatPay
The institutional infrastructure of lstBTC addresses pension funds, sovereign wealth funds, and corporate treasuries. SatPay — the Bitcoin neobank built on Core's infrastructure — addresses the millions of ordinary Bitcoin holders who face the same fundamental problem at a different scale.
They hold Bitcoin. It earns nothing. They can sell it to access liquidity — but selling means surrendering future appreciation. The consumer product layer of Core's ecosystem offers yield on Bitcoin holdings, Bitcoin-backed loans in stablecoins, and a global debit card for everyday spending — without requiring the sale of the underlying Bitcoin.
The logic is identical to lstBTC, applied at the consumer level. The infrastructure is the same. The access is universal — from a $300 million sovereign wealth fund allocation to an individual Bitcoin holder's wallet, the network's economics do not change based on the size of the participant.
The BTCfi Landscape in Context
Babylon and Core DAO are the two most architecturally significant responses to the Bitcoin yield problem — but they exist within a broader landscape of approaches that are worth mapping for institutional investors attempting to evaluate the space.
| Approach | Examples | BTC Custody | Yield Source | Key Risk |
|---|---|---|---|---|
| Bitcoin secures other chains | Babylon | ✅ Bitcoin blockchain | PoS chain tokens | Multi-token yield complexity |
| Bitcoin moves to other chains | WBTC, bridges | ❌ Custodian / bridge | DeFi protocol fees | Bridge hacks, custodian risk |
| Bitcoin anchors new ecosystem | Core DAO | ✅ Bitcoin blockchain | Protocol revenue | Ecosystem adoption risk |
| Bitcoin payments only | Lightning Network | ✅ Payment channels | Routing fees | Liquidity management |
| Emission-funded yield | Most 2024-era BTCfi | 🔶 Variable | Token inflation | Unsustainable — 74% TVL decline |

What the Infrastructure Layer Makes Possible
The infrastructure described in this article does not exist in isolation. It is the missing piece that connects the institutional capital described in Parts 1 and 2 to the outcome described in Part 4.
Without a yield layer, institutional Bitcoin allocation is capped by the subset of institutional mandates that permit pure price-appreciation assets. With a yield layer — whether through Babylon's security provisioning model or Core's full financial ecosystem model — institutional Bitcoin allocation can reach pension funds and insurance companies whose mandates require income generation alongside capital appreciation.
The yield layer does not replace the ETF pathway documented in Part 2. It complements it — extending the addressable institutional market from the subset whose mandates already accommodate price-appreciation assets to the much larger universe of institutions whose mandates require yield.
Both Babylon and Core DAO represent serious, architecturally sound attempts to build that yield layer. They serve different institutional needs, attract different types of participants, and make different trade-offs in pursuit of the same fundamental goal: making Bitcoin productive at scale.
Among the factors that may determine the pace and scale of institutional Bitcoin adoption, the development of sustainable yield infrastructure stands out as particularly consequential. The ETFs opened the first door. Regulatory frameworks provided the legal foundation. Sustainable yield infrastructure — built on protocol revenue rather than token emissions, with custody models that institutional fiduciaries can accept — is the mechanism through which the $100 trillion shift described in this series can reach its full potential rather than stopping at a fraction of it.
What that full potential looks like — and what it means for the financial system as a whole when institutional capital arrives in scale — is the subject of Part 4.
