The vision for Bitcoin has always extended beyond speculation. Since Satoshi Nakamoto introduced the concept of peer-to-peer electronic cash in 2008, the dream of a decentralized, globally accessible financial system has driven innovation across the blockchain space. Today, OKX—one of the world’s leading cryptocurrency platforms—is actively investing in that vision by supporting projects that aim to transform Bitcoin from a speculative asset into a functional, utility-driven network.
At the helm of this initiative is Jeffrey Ren Yunan, who oversees both equity and token investments in nearly 200 crypto projects through OKX Ventures, the venture arm of OKX. As chairman and CEO of OKG Technology Holdings—a Hong Kong Stock Exchange-listed subsidiary of OKG Group—Ren is uniquely positioned to bridge institutional finance with cutting-edge blockchain development.
Expanding Bitcoin’s Utility Through Layer-2 Innovation
While Bitcoin remains the most decentralized and secure blockchain, its utility has long lagged behind networks like Ethereum, Solana, or Aptos. Its original design prioritizes security and decentralization over scalability and smart contract functionality, limiting it to basic transaction settlement.
To address this, OKX Ventures has committed over $100 million across 60 projects and funds, with a growing focus on Bitcoin layer-2 (L2) solutions. These protocols are designed to extend Bitcoin’s capabilities—enabling faster payments, NFTs, DeFi applications, and cross-chain interoperability—while still relying on Bitcoin’s robust base layer for final settlement.

“Bitcoin was meant to be digital cash,” Ren said in an interview with DigFin. “Our strategy goes back to that original white paper vision—making Bitcoin usable again.”
This shift reflects a broader industry trend: rather than replacing Bitcoin, developers are building on top of it. By leveraging Bitcoin’s unmatched security and global node distribution, L2s aim to deliver the speed and flexibility users expect from modern financial systems.
Bridging Centralized and Decentralized Finance
OKX is not just investing externally—it’s also integrating these innovations into its own ecosystem. The platform operates at the intersection of centralized exchanges (CEX) and decentralized finance (DEX), offering users a unified app that combines exchange trading with self-custodial wallet functionality.
This hybrid model allows users to:
- Trade assets on a high-performance CEX
- Store funds securely with full control (“your keys, your coins”)
- Access decentralized applications (dApps) and DEXs directly from the wallet
“If crypto is a new asset class,” Ren explains, “then Web3 is the new infrastructure. We bring assets onchain—not just to trade Bitcoin or altcoins, but to connect ecosystems, like a superhighway beneath multiple layer-1s.”
This integration is critical for mass adoption. It lowers barriers for newcomers while giving advanced users the tools they need to interact with DeFi, NFTs, and emerging digital economies.
Understanding Layer-1 and Layer-2 Blockchains
To appreciate the significance of Bitcoin L2 development, it’s important to understand the distinction between layer-1 (L1) and layer-2 (L2) networks.
- Layer-1 blockchains—like Bitcoin, Ethereum, or Solana—are foundational protocols responsible for consensus, security, and transaction settlement.
- Layer-2 protocols are built atop L1s to improve scalability and functionality without compromising security.
Ethereum pioneered the L2 model due to congestion and high gas fees. Solutions like Optimism and Arbitrum process transactions off-chain before settling them on Ethereum. Now, similar models are being applied to Bitcoin.
Despite its Proof-of-Work consensus and slower block times (one every 10 minutes), Bitcoin offers unmatched decentralization and hash rate security. This makes it an ideal settlement layer—even if it can’t handle more than ~11 transactions per second (TPS) natively.
Key Bitcoin Layer-2 Projects Gaining Traction
Several innovative L2 projects are pushing the boundaries of what Bitcoin can do:
Lightning Network
Launched in 2015, Lightning enables fast micropayments by routing transactions off-chain. While limited in smart contract support, it proves Bitcoin can function as real-time digital cash.
Stacks
Using a unique “Proof of Transfer” consensus mechanism, Stacks allows developers to build smart contracts and dApps anchored to Bitcoin. Miners stake BTC to secure the network, linking its security directly to Bitcoin’s chain.
Merlin Chain & Ordinals
Merlin Chain introduces zero-knowledge proofs to enhance privacy and scalability. Meanwhile, Ordinals enable NFT-like inscriptions directly on Bitcoin blocks—reviving interest in on-chain data storage.
BOB (Build on Blockchain)
Born from Babylon Chain’s rollup technology, BOB aims to bring staking and cross-chain compatibility to Bitcoin-based applications. Unlike earlier sidechains, BOB doesn’t require pre-funding and supports larger transaction volumes.
Blockstream’s Liquid Network
A federated sidechain used primarily by institutions, Liquid enables issuance of digital assets with faster settlement—all backed by Bitcoin’s finality.
Challenges Facing Bitcoin L2 Adoption
Despite progress, significant hurdles remain:
- Security risks: Sidechains and rollups introduce new attack vectors. Hackers have exploited vulnerabilities in multi-signature wallets and bridge contracts.
- Scalability limits: Even with L2s, final settlement on Bitcoin remains slow and costly during peak demand.
- Volatility: Bitcoin’s price swings make it impractical as everyday money. In El Salvador—the first country to adopt Bitcoin legally—usage has declined sharply since 2021. Only about 1% of remittances now use crypto wallets.
Surveys show public adoption dropping from 25% in 2021 to just 8% in 2024 among Salvadorians using Bitcoin for purchases.
Beyond Payments: New Use Cases for Bitcoin Ecosystems
Ren believes true utility extends beyond payments. OKX Ventures is exploring investments that create entirely new markets:
Story Protocol
In a recent $80 million Series B round led by a16z, OKX participated in funding Story Protocol—an IP licensing platform that uses blockchain to automate franchising, royalties, and dispute resolution. This could empower creators whose work is scraped by AI models, allowing them to monetize digital rights transparently.

Tokenized Incentives for Research
Ren also sees potential in using crypto to fund non-commercial research. Imagine PhD students earning tradable tokens for solving complex mathematical problems—redeemable for access to premium datasets or cloud computing resources. This mirrors traditional “soft dollar” arrangements in finance but adds transparency through tokenization.
“These aren’t just rewards,” Ren notes. “They’re programmable incentives that can scale social value.”
The Path to Mass Adoption: Priest, Speculator, Builder
Ren offers a philosophical framework for innovation: “To succeed, anything needs a priest, a speculator, and a builder.”
- The priest evangelizes the vision (e.g., Satoshi Nakamoto).
- The speculator creates market liquidity and price discovery.
- The builder—like OKX Ventures—funds infrastructure that enables stability and adoption.
“I want that speculative element,” Ren says. “It creates a natural market.” But speculation alone isn’t enough. Long-term success depends on real-world utility.
Financial Realities: Profitability vs. Vision
Despite strong user growth—with $50 billion in self-custodied wallet assets and $22.3 billion on its exchange—OKG Technology Holdings reported a HK$40 million loss in its 2024 annual report. A follow-up interim report through September 31 also showed losses.
The company attributes this to volatility in its digital asset trading operations—even as Bitcoin surged in early 2024. This highlights a key challenge: even firms deeply aligned with crypto’s future face financial instability when tied too closely to asset prices.
Yet Ren remains focused on long-term infrastructure investment. “We’re building the rails,” he says, “not just riding the rally.”
