Annabelle Huang warns that the long‑heralded march of institutional capital into blockchain markets is being stalled not by investor appetite but by a structural bottleneck at the technology and compliance layer. In her analysis, persistent shortcomings – from scalability and interoperability to custody, auditability and regulatory clarity – are preventing banks, asset managers and corporate treasuries from deploying meaningful on‑chain exposure at scale. The result, she argues, is a slow drift of enterprise interest toward pilot projects rather than production‑grade deployments, leaving innovation constrained until vendors, standards bodies and regulators align on robust infrastructure and governance. This article examines Huang’s assessment of the barriers and the pathways industry stakeholders are exploring to unlock institutional participation.
Institutional Adoption Faces Blockchain Bottleneck, Says Annabelle Huang
According to Annabelle Huang, institutional demand for Bitcoin has outpaced the base-layer capacity and related infrastructure that institutions require for large-scale participation. On-chain throughput for Bitcoin remains roughly 3-7 transactions per second (TPS) with an average block time near 10 minutes, and despite improvements such as SegWit (adoption estimates commonly cited above 80%), institutions face meaningful operational friction when moving large volumes on-chain. Consequently,episodes of heightened market activity have produced volatile transaction fees and mempool backlogs,which translate into tangible execution and settlement risk for custodians,asset managers,and corporate treasuries that need predictable finality and low-cost settlement windows.
Technically, the constraint is not merely raw block capacity but the interaction of Bitcoin’s UTXO model, block interval, and the security properties institutions demand. For that reason, many market participants look to Layer‑2 and sidechain solutions-most notably the Lightning Network for payments and federated sidechains such as Liquid for faster settlement-to alleviate congestion while preserving Bitcoin’s security model. However,these approaches introduce trade-offs in terms of counterparty risk,liquidity management and,in some cases,partial trust assumptions. Thus, as Huang emphasizes, institutional adoption is as much a product of robust custody, insurance, and operational tooling as it is indeed of raw protocol throughput.
From a market and regulatory perspective, the environment has evolved: the approval of spot Bitcoin exchange‑traded products and growing ETF inflows have concentrated more institutional exposure into regulated vehicles, increasing demand for qualified custody and clear proof‑of‑reserve practices.At the same time, heightened regulatory scrutiny-on KYC/AML, AML‑focused transaction monitoring, and custody governance-has raised compliance costs and slowed onboarding for some institutions. Thus, while spot products have lowered the regulatory entry bar in one sense, they have simultaneously amplified the need for institutional‑grade infrastructure that mitigates counterparty, custody, and settlement risks.
For market participants seeking practical next steps,the landscape suggests clear,differentiated actions for newcomers and veterans alike. Newcomers should prioritize working with regulated custodians, understand private‑key custody models (cold storage, multisig, and insured custodial services), and use dollar‑cost averaging to manage execution risk.Experienced operators should focus on liquidity routing, fee optimization, and Layer‑2 integration while demanding transparent proof‑of‑reserves and SOC‑type audits from counterparties. in particular, consider the following operational checklist:
- Custody best practices: multisig, hardware wallets, and insured custody solutions
- Execution tactics: batching transactions, off‑chain settlement channels, and negotiated OTC trades to reduce on‑chain footprint
- Risk controls: real‑time monitoring of mempool and fee markets, and contingency plans for extreme congestion
- Regulatory readiness: documented KYC/AML procedures and clear audit trails for reserves and settlement
Scalability, Interoperability and Compliance Emerge as Primary Barriers
Bitcoin’s base-layer design imposes clear throughput and latency constraints that remain central to scaling debates. The network’s average block interval of roughly 10 minutes and on-chain capacity in the order of 3-7 transactions per second (tps) mean that large-volume payment rails and institutional settlement needs cannot be met solely on layer one. Segregated Witness (SegWit) and the block weight mechanism (up to 4 million weight units) have improved efficiency and reduced some fee pressure, while soft-fork upgrades such as Taproot have enabled more compact signatures and smarter script constructions. Still,during periods of high demand fees can spike-sometimes increasing median confirmation costs by multiples within hours-illustrating that base-layer capacity remains an economic bottleneck rather than a purely technical one.
Consequently, layer‑2 and sidechain solutions have risen to prominence, but they bring their own trade‑offs. The Lightning Network lowers settlement times to milliseconds and can aggregate many small payments off-chain,improving effective throughput dramatically; however it requires active liquidity management,introduces routing and channel exhaustion risks,and may present usability hurdles for retail users. Federated and federating sidechains such as Liquid and smart‑contract platforms that host wrapped Bitcoin (such as WBTC) provide faster settlement and programmability at the cost of counterparty or smart‑contract risk. Interoperability tools-atomic swaps, cross‑chain bridges, and messaging protocols-help connect bitcoin to the broader crypto ecosystem, yet they vary in trust assumptions and attack surface, meaning that integration frequently enough substitutes one kind of risk (custodial or protocol) for another.
Regulatory and compliance requirements compound technical frictions and shape market outcomes. As noted in ”Institutional adoption faces blockchain bottleneck: Annabelle Huang insights,” institutions increasingly cite not only throughput but also transaction finality, chain surveillance, and KYC/AML obligations as gating factors for Bitcoin exposure. Regulatory frameworks such as the FATF Travel Rule and the EU’s MiCA (and intensified enforcement activity in several jurisdictions) encourage institutional actors toward regulated custodians, proof‑of‑reserve standards, and enhanced on‑chain analytics-measures that improve compliance but can increase latency, cost, and operational complexity. Therefore, institutional flows tend to prefer custody solutions that combine multi‑signature setups, regulated custodians, and thorough compliance tooling, even if those solutions reduce some decentralization properties.
For market participants seeking practical next steps, several mitigations can ease these barriers while managing trade‑offs. Newcomers should prioritize secure custody and low‑cost access: consider hardware wallets for long‑term holdings, choose regulated exchanges for fiat on‑ramps, and learn the basics of fee estimation and transaction batching to reduce on‑chain costs. Experienced participants and institutional operators can focus on operational improvements and integration strategies, such as:
- Layer‑2 liquidity management: provision channels on Lightning or use liquidity protocols to avoid routing failures.
- Custody best practices: multi‑sig custody, periodic proofs of reserve, and third‑party audits to satisfy counterparties and regulators.
- Interoperability hygiene: prefer non‑custodial atomic swaps or audited bridges and monitor smart‑contract risk metrics.
- Compliance tooling: deploy on‑chain analytics and transaction monitoring to meet KYC/AML obligations while minimizing settlement friction.
scalability, interoperability and compliance are tightly coupled constraints: technological fixes such as layer‑2s and sidechains can expand capacity, but institutional adoption will depend equally on robust custody, reliable compliance practices, and interoperable standards that preserve both capital efficiency and regulatory certainty.
Financial Institutions Demand Stronger Security and Regulatory Clarity
Large financial firms are increasingly demanding institutional-grade controls before committing significant capital to digital assets. This demand is driven by the operational differences between traditional finance and crypto rails: private key custody, on-chain settlement finality, and smart-contract counterparty risk require new control frameworks. furthermore, episodic industry failures – most notably exchange collapses that exposed weak custody and governance – have pushed asset managers and banks to insist on audited custody arrangements, transparent proof-of-reserves disclosures, and independent attestations. As noted in “Institutional adoption faces blockchain bottleneck: Annabelle Huang insights”, bottlenecks in throughput and reconciliation persist, which amplifies the need for robust custody and settlement solutions when billions of dollars flow into spot Bitcoin via regulated products and futures markets.
Technically, many of the institutional concerns trace to how blockchains achieve consensus and transaction finality. For Bitcoin, an average block time of ~10 minutes and customary reliance on multiple confirmations (commonly 3-6 for lower-value transfers, higher for institutional settlement) lengthen settlement windows compared with real-time gross settlement in traditional banking. Consequently, institutions favor custodial arrangements that combine cold storage, hardware security modules (HSMs), and multi-party signing schemes such as multisignature or MPC (multi-party computation) to reduce single-point-of-failure risk. moreover, settlement scalability constraints make layer-2 solutions (for example, the Lightning Network for payments) and centralized clearing mechanisms attractive, though those introduce trade-offs between decentralization and regulatory compliance that regulators in jurisdictions under MiCA, FATF guidance, or ongoing SEC scrutiny continue to scrutinize.
For market participants seeking practical steps, the following actions are recommended:
- Newcomers: use hardware wallets for self-custody, choose custodians with SOC 2 or SOC 1 reports, verify proof-of-reserves publications, and require clear insurance terms for hot-wallet exposures.
- Experienced operators: deploy layered key-management (MPC + cold multisig), run independent third-party audits, integrate on-chain analytics for real-time counterparty monitoring, and stress-test settlement flows under high-fee or congested-chain scenarios.
- Policymakers and compliance teams: collaborate on standardized APIs for attestations, define minimum audit frequency (for example, weekly or continuous Merkle-root updates), and harmonize KYC/AML rules to reduce fragmentation across jurisdictions.
These steps help align operational security with regulatory expectations while keeping exposure transparent and measurable.
balancing opportunity and risk requires continued industry and regulator cooperation. While regulated spot products and cleared futures have opened pathways for institutional allocation, they also magnify the need for clear capital treatment, resilient custody protocols, and interoperable settlement infrastructure. Thus,along with adopting best-practice technical controls,institutions should advocate for a predictable regulatory baseline that defines acceptable custody certifications,disclosure standards,and capital requirements. Doing so will reduce friction from the identified blockchain bottlenecks,enhance market integrity,and create a safer environment for both retail and institutional participants to engage with Bitcoin and the broader cryptocurrency ecosystem.
Technological Upgrades and Policy Coordination Required to Unlock Institutional Capital
Institutional interest in Bitcoin has progressed from theoretical curiosity to tangible allocation, but significant hurdles remain before large pools of capital fully enter the market. At the protocol level,Bitcoin’s layer‑1 design prioritizes security and censorship resistance over high throughput: block time is roughly 10 minutes and native transaction capacity averages around 7 transactions per second,which can create congestion during demand spikes and lead to elevated fees and settlement delays. Consequently, as industry observers note-most recently framed in the refrain “Institutional adoption faces blockchain bottleneck: Annabelle Huang insights”-many custodians and treasury managers are reluctant to base enterprise settlement workflows solely on on‑chain finality without robust off‑chain or settlement‑layer complements. For example, the growth of the Lightning Network into the low thousands of BTC of capacity demonstrates one scalability path, but it also illustrates that layer‑2 liquidity and routing remain operational challenges for institutional flows.
To address these constraints, a suite of technological upgrades and integration work is required across multiple layers of the stack. At the protocol and layer‑2 level, continued deployment of privacy‑preserving signing schemes, batching and fee‑optimization techniques, and mature implementations of state channels and sidechains (such as Liquid‑style settlement rails) will reduce settlement latency and lower total cost of custody. Equally vital on the infrastructure side are advances in custody technology-specifically,institutional‑grade multi‑party computation (MPC),audited multisignature solutions,hardware security modules (HSMs),and standardized insurance frameworks-that collectively lower operational and counterparty risk. Practical steps include:
- Prioritizing integrations with tested layer‑2s and federated sidechains to offload high‑frequency settlement.
- Adopting MPC/multisig standards with third‑party attestations (SOC 2/SOC 1) to meet institutional audit requirements.
- Implementing automated reconciliation and pre‑ and post‑trade monitoring to bridge blockchain events with custodial accounting systems.
Policy coordination must move in lockstep with technical progress to unlock scale. Regulators and industry participants need clearer definitions of custody, settlement finality, and permissible institutional practices; harmonized KYC/AML and stablecoin rules; and frameworks for cross‑border settlement that reduce legal and settlement risk. The approval of regulated investment vehicles-such as spot Bitcoin ETFs in several jurisdictions-has already shown that regulatory clarity can catalyze flows, but sustained adoption requires ongoing dialogue on insurance minimums, insolvency treatment of digital assets, and guarded sandbox environments to test systemic implications. Actionable policy steps include:
- Establishing regulated custody standards that recognize modern cryptographic key management (e.g., MPC, hsms, multisig).
- Creating time‑limited regulatory sandboxes to pilot institutional settlement protocols and cross‑institution atomic settlement.
- Coordinating internationally on tax and disclosure rules to reduce regulatory arbitrage and operational complexity for global asset managers.
both newcomers and seasoned market participants can act now to prepare for a more institutionalized Bitcoin market. New entrants should prioritize secure custody, consider conservative allocations (many institutions evaluate 1-3% of total portfolio for digital assets), and use dollar‑cost averaging to manage volatility exposure. Meanwhile, experienced firms should invest in operational readiness: integrate reconciliation with on‑chain data feeds, stress‑test custody and settlement under high‑fee conditions, and participate in standards development to reduce fragmentation. Transitioning institutional capital into Bitcoin is as much a question of engineering and process as it is of regulation; therefore, the most durable progress will come from coordinated upgrades that align cryptographic realities with clear legal and operational frameworks, thereby reducing both technical and institutional frictions.
As institutional players weigh the promise of blockchain against persistent technical, regulatory and operational frictions, the path to widespread adoption remains contested. Annabelle Huang frames these barriers – from scalability and interoperability to custody and compliance – not as insurmountable flaws but as a call to coordinated action: clearer regulatory frameworks,interoperable standards,robust security practices and pragmatic partnerships between legacy institutions and crypto-native teams.
Progress, Huang suggests, will be incremental and measured.Pilot programs, common-sense guardrails and industry-wide standards can reduce risk and build the trust that institutional balance sheets demand. yet without sustained investment in infrastructure and cross-sector collaboration, the current bottleneck risks slowing a conversion that many believe could redefine finance.
Ultimately, the question is not whether blockchain can deliver change, but whether the industry can marshal the technical, legal and governance solutions required for institutions to move from cautious experimentation to confident deployment. As Annabelle Huang and othre observers note, the coming years will determine whether blockchain becomes an integral layer of institutional finance - or remains an intriguing but peripheral technology.
