🇸🇬 See you in Singapore. We will be at the Barouv Rooftop at Token2049, and you won't want to miss the second edition of the Bitcoin programmability summit, bringing the top minds on the frontier of Bitcoin together.

📈 Strategy leads BTC surge. Bitcoin surged to $114K Monday, as Strategy expanded its BTC Treasury to $47 Billion.

💷 The Sterling gets tokenized. UK Finance launched a tokenized deposits pilot in partnership with six major banks, including Barclays, HSBC and Lloyds Banking Group, CoinTelegraph reports.

Enabling BTC-backed Real Estate

In the growing conversation about RWAs, real estate is the flagship category: bigger than gold, credit, or equities combined.

The same forces driving tokenization of Treasuries and private credit apply here, with liquidity, accessibility, and composability as key factors.

The difference is scale.

At $300T, real estate alone will require trillions in TVL to operate onchain.

That’s why Bitcoin, with its unmatched liquidity and security, is the only credible settlement layer for real estate RWAs at scale … and that’s why Arch exists: to make those RWAs productive, natively on Bitcoin.

Tokenization promises to change that, fractionalizing property into digital tokens that can be traded, borrowed against, or plugged into financial markets as easily as stablecoins are today.

This opens up liquidity for owners, and also access for investors.

Anyone, anywhere, could own a slice of income-producing real estate, with transparent yields and programmable contracts governing payouts.

Why Tokenized Real Estate Matters

Liquidity: Transform a building into thousands of tradable tokens, enabling faster sales, refinancing, and capital flows.
Accessibility: Lower the barrier to entry, so retail investors can access property markets previously reserved for institutions.
Efficiency: Automated payouts, transparent records, and instant settlement replace months of paperwork and escrow.
Composability: Once tokenized, real estate can plug into DeFi: used as collateral, securitized into pools, or built into structured yield products.

This is the trillion-dollar opportunity: real estate isn’t niche, it’s the premier market.

However, tokenizing real estate will eventually need trillions in Total Value Locked (TVL).

Which raises the question: what blockchain can credibly hold that much value?

Why Bitcoin Is the Natural Settlement Layer

Currently, there is only one answer: Bitcoin.

Deepest Liquidity: Bitcoin is the $2T+ base layer of crypto. If you’re securing trillions in real estate, you want to anchor it against the only asset with comparable depth.
Strongest Security: Proof-of-work, unmatched decentralization, and 15 years of resilience make Bitcoin the least capture-prone base chain.
Credible Neutrality: Institutions are wary of ecosystems controlled by single foundations or geographies. Bitcoin’s neutrality makes it the most trusted base layer for global-scale settlement.
Regulatory Support: Bitcoin is the most well-known and generally supported cryptocurrency among both business leaders and political figures, which is why nations have mapped out much clearer regulatory roadmaps for it over other blockchains.

How Arch Makes It Possible

Until now, Bitcoin couldn’t host tokenized real estate.

Its base layer is too limited, and other chains force assets to be wrapped or bridged, introducing risks institutions won’t accept.

Arch changes this.

By extending Bitcoin with a high-performance execution environment, Arch allows real estate tokens to be issued, collateralized, and settled natively against BTC.

That’s why major real estate holders are already working with Arch to bring their assets onchain, on Bitcoin.

Tokenization is the next big wave. Real estate will lead the charge.

And with Arch, those trillions in property value can finally be paired with the trillions in Bitcoin liquidity, creating a secure, liquid foundation for the future of global markets.

Product updates:

We released Arch Network v0.5.12 (2025-09-23) with major improvements across programmability, reliability, and developer experience.

Key Highlights

New On-Chain Program: Integrated arch-token-metadata, with builds now wired into gossip tooling.
Versioning Simplification: Centralized versioning across the workspace—workflows now auto-derive VERSION for token + associated-token-account.
Reliability Gains: Added an execution result cache, atomic update fixes, hardened BTC account handling, and early-error correctness.
Telemetry & Metrics: Expanded DB metrics and reference-based telemetry for better visibility and tuning.
CLI & UX: Standardized address output to base58 (instead of hex), removed deprecated --auto-create-ata flag, and refreshed docs/demos.
Structural Refactors: Moved network messages/mode into arch_structs for cleaner reuse.
Node Ops: Support for starting with a secret key file + new “with seeds” system program instructions.
TPU Robustness: Added missing error handling and resolved a Titan async blocking issue.

Performance & Observability

Execution result cache improves throughput under load.
Expanded telemetry + DB metrics provide deeper operator insights.

Migration Notes

If importing network messages/mode directly, update to arch_structs.
Ensure scripts rely on base58 addresses from arch-cli.
No breaking changes at the protocol or API level.
