With the Federal Reserve increasingly likely to begin rate cuts in September, market liquidity is expected to improve significantly, driving a continuous influx of capital into the Bitcoin market. This surge of funds is poised to push Bitcoin's price higher, attracting even greater investor attention.
As Bitcoin’s price rises, it triggers a "rising tide lifts all boats" effect—investors become increasingly interested in various projects and applications within the Bitcoin ecosystem. This virtuous cycle of improved liquidity and rising prices will lay a solid foundation for the prosperity of the Bitcoin ecosystem.
Looking back at the period preceding last year’s bull run, the surge in popularity of Ordinals and the wealth effect generated by inscriptions redirected significant market attention toward the Bitcoin ecosystem. As the market gradually recovers, this article explores potential tokenized projects within the Bitcoin ecosystem, helping readers seize new opportunities in the upcoming bull market.

A Bitcoin Layer 2 utilizing a Rust-based zero-knowledge virtual machine (ArchVM) and a decentralized validator network, offering developers an efficient and scalable application environment.
6. Bitfinity Network: $7 million total funding from Polychain, ParaFi Capital, and others.
An EVM-compatible Bitcoin Layer 2 using Solidity and leveraging IC’s unique architecture and Chain Key technology, achieving performance comparable to traditional web services without requiring gas fees.
7. Zulu Network: $3 million total funding from Waterdrip Capital, Cryptogram Venture, and others.
A Bitcoin Layer 2 featuring a unique two-layer architecture. ZuluPrime (L2) enables EVM compatibility, while ZuluNexus (L3) acts as a third layer for Bitcoin, offering enhanced security guarantees.
8. Citrea: $2.7 million total funding from Galaxy, Delphi Digital, and others.
The first zero-knowledge proof-based Layer 2 in the Bitcoin ecosystem, utilizing a bidirectional peg architecture to deliver the first-ever general-purpose, trust-minimized Bitcoin L2 solution, expanding Bitcoin’s programmability and use cases.
9. Fractal Bitcoin: Funding undisclosed, co-developed by UniSat and Block Space Force.
A Layer 2 scaling solution based on Bitcoin’s core code, aiming to enhance transaction processing speed and capacity through recursive creation of infinite layers while maintaining full compatibility with the Bitcoin main chain.
L2 Pre-Testnets

02 Summary
From a broader perspective, Bitcoin’s (BTC) value proposition has evolved over more than a decade, and its role as a store of value is now widely recognized.
Regulatory developments, ETF approvals, and macroeconomic factors like interest rate cuts have significantly influenced its market performance, indicating Bitcoin’s growing integration into traditional institutional portfolios.
As Bitcoin’s store-of-value narrative gains broader societal acceptance, the ecosystem of derivative financial products and innovations around it will continue to expand.
Despite potential scalability challenges with Layer 2 solutions and inherent difficulties stemming from the UTXO model, the Bitcoin sector will inevitably continue to mature and evolve—both a technological and societal imperative.
