What's next for the Bitcoin ecosystem? Exploring potential opportunities
Ultimately, I will have an experience, performance, and smart contract functionality nearly identical to that of ETH and its L2.

This article explores the future challenges and potential opportunities of BTC inscriptions, and how BTC's L2 will inject new vitality into the ecosystem.
Four Waves of Impact
The first wave was the community’s consensus-building around fair distribution. BRC20 created a completely new type of asset unlike traditional FTs or NFTs—an innovation rooted in blockchain’s first principles—and symbolized the rise of grassroots culture.
The second wave is what we are currently experiencing: a cultural renaissance within the Bitcoin inscription space, with large capital and exchanges now participating in the consensus. More developers have entered the inscription world, launching numerous innovative protocols that have spilled over to other blockchains. Bitcoin’s culture is becoming dominant—though this has also triggered some side effects.
The third wave may be the explosion of scaling solutions built “on top of inscriptions.” The rapid growth during the second wave fueled the prosperity of the BTC ecosystem but intensified competition for BTC network resources, eventually clashing with BTC’s conservative purists. At the same time, poor user experience remains a barrier for broader adoption. Therefore, scaling inscriptions themselves (rather than scaling BTC directly) has become urgent and necessary. However, developing native BTC Layer 2 solutions (such as BitVM) is technically difficult and time-consuming. As a result, compromise solutions will likely emerge first—over the next six months, we may see a surge of new BTC sidechains that treat inscriptions as native assets (unlike STX), bringing mainchain inscriptions onto these chains via cross-chain mechanisms.
The fourth wave represents the full maturity of ultimate “BTC-based” scaling solutions—featuring full smart contract capabilities, improved performance, and strong security inherited from BTC. High-value inscription assets will demand higher security standards, making more native, authentic, and secure Layer 2 solutions increasingly important. These L2s would use the BTC chain as a data availability (DA) layer, submit proofs, and even allow verification by the BTC network itself—examples include BitVM and Atomicals’ AVM protocol. With strong authenticity guarantees, BTC will be increasingly drawn into the inscription ecosystem.
Ultimately, we could achieve an experience nearly indistinguishable from Ethereum and its L2s—in terms of performance, functionality, and smart contracts—but backed by Bitcoin’s vast community and capital, centered on the core ethos of “fair distribution,” and built natively around “inscriptions” as primary assets.
Next Stop: L2
After the dramatic wave of novel asset distribution, the core narrative of “inscriptions” has largely been established. We now stand at the threshold of new opportunities and challenges.
Relying solely on fair distribution or meme-driven narratives, a $200 million market cap seems to be a hard ceiling. Without grounded, sustainable development, it’s difficult to break through this limit (the end of fair distribution often leads to manipulation). As the market returns to rationality, utility becomes more critical—either offering enhanced functionality or serving as foundational assets.
Sidechains built “on inscriptions” may represent the next major step. They are referred to as sidechains rather than L2s because these “L2s” won’t inherit BTC’s security.
But just as Polygon relates to ETH, inscription L2s can effectively lower the barrier to entry for users while finding middle ground with BTC’s conservative factions. Most importantly, full smart contract capabilities will unlock many new use cases for inscriptions—DeFi, SocialFi, GameFi, and beyond.
BRC20 and its various derivative inscriptions store token information in human-readable JSON format. One key advantage is extreme flexibility—tokens can be split into any quantity under the “amt” field.
This flexibility makes them highly compatible with inscription Layer 2s. As long as the L2 reads the JSON and reconstructs the BRC20 state, subsequent applications like DeFi become much easier to implement.
As a new asset class distinct from both NFTs and FTs, inscription L2s should build their business models around inscriptions themselves—with ideally using inscriptions as the native asset. If an inscription L2 merely bridges inscriptions, converts them into FTs, and replicates Ethereum-style DeFi, it will lack appeal, since trading FTs already offers low value for today’s traders.
Since the BRC20 index itself functions as a ledger, reading this index enables the creation of EVM-compatible chains that preserve inscription properties, allowing continuous innovation of application paradigms beyond traditional FT-based DeFi.
Programming for Indexers
Must BRC20 and other JSON-based inscription sidechains inevitably follow Ethereum’s model? In fact, EVM sounds rather dull—we don’t need to reinvent another set of L2s. Perhaps starting from the intrinsic nature of inscriptions and building outward based on their unique features would be far more interesting.
BRC20 is an on-chain record system that uses BTC as storage. For scaling such systems, perhaps more business logic can be implemented off-chain through indexer servers.
For example, introducing new primitives beyond “mint,” “deploy,” and “transfer” within the JSON “op” field—such as listing, collateralizing, burning, or authorizing—could enable advanced functionalities. Combinations of these “op” types could evolve into swaps, lending, and other Inscription-Fi (Inscription Finance) applications, even extending to complex SocialFi and GameFi ecosystems.
This approach is essentially programming for indexers—akin to developing web2 server APIs. It’s relatively simple to implement and could start from a single indexer server, yet yield significant results quickly. Current examples include Unisat’s swap features, along with protocols like BRC100, ORC20, and Tap, all pioneers in this JSON-based scaling movement, capable of driving rapid change.
Experimenting with cryptographic primitives is exciting. However, decentralization must always remain a priority. Programming for indexers inherently increases server load and makes community operation more challenging. Complex applications will ultimately require consistent consensus, pushing the system toward full-fledged smart contract platform development.
Or… A More Native Approach
There are two main schools of thought regarding issuance methods on the BTC base layer. Beyond the previously discussed JSON-based approach, there is Atomicals’ unique UTXO-based model (Rune’s definition remains ambiguous and is not discussed here).
Atomicals’ ARC20 tokens are directly represented by BTC’s UTXOs without relying on JSON updates. This allows ARC20 tokens to support intriguing functionalities—such as direct swapping between ARC20 tokens and BTC, or consuming one ARC20 token to generate another.
Fine-grained control over transaction inputs and outputs can also enable basic DeFi functions, though this demands greater technical expertise and poses higher development barriers. The benefits, however, are clear: all logic is processed directly by the BTC network, inheriting its maximum security and consensus. It also allows seamless integration with BTC assets without relying on third-party bridges—a crucial point given the principle of “not your keys, not your coins.”
Clearly, ARC20 itself isn’t Turing-complete. Hence, drawing inspiration from BitVM, the Atomicals protocol has proposed AVM—a Bitcoin Layer 2 solution that submits proofs on the BTC mainnet for validation via BTC script circuitry. As UTXO-represented assets, ARC20 tokens naturally serve as ideal collateral for fraud proofs on the AVM Layer 2.
This represents BTC’s ultimate scaling narrative: achieving smart contract functionality while leveraging BTC’s data availability and shared security.
This may be an L2 that only materializes during the fourth wave, but @wizzwallet, a developer service provider for Atomicals, recently hinted at AVM developments—progress might be faster than I expected.
