Bitcoin’s Next Chapter: How Citrea and ₿apps Reclaim Bitcoin’s Utility

Bitcoin was envisioned as peer-to-peer electronic cash, free from intermediaries and censorship. Yet in 2025, Bitcoin largely functions as digital gold — stored passively, traded on centralized exchanges, or wrapped into other ecosystems.

Billions in value flow away from the Bitcoin network each year. Its role as a censorship-resistant financial layer has been undermined.

This is about to change.

Citrea a L2 solution for Bitcoin introduces a new class of Bitcoin-native applications, ₿apps, are building the missing infrastructure to bring utility back to Bitcoin.

Value Drain from Bitcoin

• In 2024, exchanges earned — $2.8B in BTC trading fees, nearly 3× more than Bitcoin miners did in transaction fees.

~ 2.4M BTC (11% of supply) sits on centralized exchanges.

~243,000 BTC (1.2% of supply) circulates as wrapped tokens on other chains.

This is a structural leakage of value

• Liquidity leaves Bitcoin for centralized or wrapped venues.
• Developers build elsewhere, draining innovation and mindshare.
• Users face custodial risk (KYC, censorship, hacks).Bitcoin’s scarcity is intact. Its utility, however, is being drained.

Root Cause — No Infrastructure, No Ecosystem. Bitcoin always had demand for applications. But it lacked the infrastructure. Early projects like Ethereum started with Bitcoin but migrated due to scalability and tooling limitations. No shared developer stack meant isolated experiments, no network effects, and no composability.

But Now The Table Turns:

Over the past five years, a builder movement has reignited Bitcoin’s potential. Experiments in:

~ Ordinals, Runes, BRC-20s (native assets).

~ Discreet Log Contracts (DLCs).Zero-knowledge rollups for scalability.

~ BitVM for complex Bitcoin-compatible computation.

Builders are now establishing best practices and shared infrastructure.

At the heart of this movement lies Citrea.

Citrea’s Role — ZK rollup for Bitcoin

Citrea introduces zk-rollups to Bitcoin:

~ State transitions are batched, proven with zkSNARKs/STARKs.

~ Bitcoin functions as the ultimate settlement layer.

~ Light client proofs ensure security for even small participants.

This gives Bitcoin the scalability and composability it has always lacked — without compromising trustlessness.

Citrea introduces ₿apps — The Bitcoin Application Layer

A non-custodial Bitcoin application using BTC or BTC-denominated assets, secured by the Bitcoin network.

₿apps reimagine Bitcoin’s role beyond passive storage:

• Financial Primitives: BTC loans, trustless DEXs, fast payment systems.
• Everyday Finance: P2P lending, remittances, savings protocols.
• Niche Use Cases: RWA purchases, gaming, betting, on-chain marketplaces.

With ₿apps, Bitcoin becomes the most liquid, widely used asset on-chain.

Bitcoin’s original vision wasn’t digital gold — it was digital cash. Over time, the infrastructure gap left Bitcoin sidelined while intermediaries captured its value.

Today, that gap is closing. With Citrea and ₿apps, Bitcoin can reclaim its role as the foundation of a decentralized, censorship-resistant financial system.

The tools are here. The demand is here. The time to build is now.
