After the Fomo wave of inscriptions, how should the Bitcoin ecosystem achieve real-world adoption?
The contradiction of the impossible trinity—security, decentralization, and scalability—is more pronounced on the Bitcoin mainnet.

As the FOMO wave of inscriptions sweeps through, I’ve spoken with some "true" Bitcoin developers and found they remain level-headed—no wild claims about Bitcoin Layer 2s overtaking Ethereum.
Instead, there’s a shared understanding: the Bitcoin ecosystem has potential, but it must differ fundamentally from Ethereum’s DeFi Lego-composition paradigm. Let’s explore, based on technical logic, how the Bitcoin ecosystem can realistically take shape.
Indeed, the new asset issuance method via inscriptions has brought many back to the 2017 ICO era, reigniting enthusiasm. This inscription boom has attracted new users, new use cases, and fresh capital—so much so that calling this bull market a “Bitcoin bull run” isn’t far-fetched.
As a result, various camps—sidechains, Lightning Network, Taproot Assets, RGB, BitVM—are vying for recognition as Bitcoin’s “orthodox” Layer 2 solutions. Each proclaims grand ambitions to replicate everything Ethereum has built, sparking intense excitement.
Just as the ICO asset issuance frenzy was unsustainable, the inscription market now hopes to ride the post-FOMO wave into a new era of Bitcoin Layer 2 innovation.
Such ambition is valid—but replicating Ethereum’s diverse ecosystem on Bitcoin simply won’t work (see top article on homepage). The Bitcoin ecosystem must find a path aligned with its native characteristics.
The core issue lies in Bitcoin’s inherently “limited” computation and verification capabilities. Even storage within Taproot SegWit addresses faces controversy over dust attacks.
Limited computation means complex transaction logic must be handled off-chain. For instance, BitVM boldly proposes a Turing-complete system using off-chain circuits combined with on-chain logical gates (0/1), inspired by optimistic Rollup principles. It's an imaginative and technically sound idea—but the engineering complexity rivals the human-based computer in *Three Body Problem*, making it impractical.
Limited verification makes Bitcoin better suited for asset settlement rather than global state validation. While Schnorr signatures and MAST data structures offer some improvements—Schnorr aggregates multiple signatures (still limited to multisig scenarios), and MAST enables more complex scripts—they rely on the UTXO model, which supports only asset settlement, not full state validation. Deploying complex light node matrices can improve interoperability between sidechains and mainchain, enhancing security and speed of asset settlement—but nothing beyond that.
Storage limitations are unquestionable. Bitcoin has always followed a minimalist philosophy—a consensus forged after the great block size debate. Any attempt to exploit Taproot script space will fail. While we may avoid a full SegWit-style fork, newer protocols like Atomicals, RUNE, and PIPE have all compromised toward smaller blocks—discarding bulky JSON payloads and returning to optimized use of OP_Return space.
These constraints mean Bitcoin’s Layer 2 expansion differs fundamentally from Ethereum’s:
1) Bitcoin lacks Data Availability (DA) capability. On Ethereum, DA refers to validators on the mainnet verifying data submitted by Layer 2s. Bitcoin can store data, but its mainnet lacks efficient computational and verification mechanisms. Thus, Bitcoin’s DA functions more like a “bulletin board,” where raw data is stored in blocks and indexed off-chain by indexers for accounting and ownership verification.
This places heavy demands on indexer reliability. With multiple competing indexers, conflicting records could lead to accounting chaos and errors.
2) Bitcoin’s interoperability is constrained. On Ethereum, Layer 2s submit state to the mainnet, enabling safety features like a 7-day challenge period or a “bridge escape hatch” to protect users if the sequencer acts maliciously. Bitcoin, lacking smart contract functionality, offers no such safeguards. Users must simply trust their Layer 2 won’t cheat.
3) Bitcoin’s UTXO security model is confined to “payment” use cases. Similar to Ethereum’s Plasma, if every transaction’s nonce hash were synchronized with the mainnet via UTXOs, an absolutely secure model could theoretically exist. But just as Plasma is limited to payments, so too is any Bitcoin Layer 2 built purely on UTXO. Complex systems like EVM with multi-state smart contracts cannot rely solely on this mechanism without adding external off-chain consensus layers.
Given these technical realities, the narrative for Bitcoin Layer 2 becomes clear:
1) Use Bitcoin as a settlement layer, while building independent consensus layers on top that provide full-stack capabilities—DA, interoperability, VM execution—to support an Ethereum-like ecosystem. However, such powerful chains would essentially recreate an Ethereum execution layer. Many forget that Ethereum itself has a Beacon Chain as its settlement layer; Ethereum 2.0’s execution layer is effectively a Layer 2 atop Beacon.
The reason settlement chains feel invisible is because the mainnet’s primary role is interaction and verification. If you offload computation and verification elsewhere, that secondary chain becomes the de facto “main chain.”
So here’s the question: if we make Bitcoin the settlement layer, would another chain dare call itself the main chain? Would the Bitcoin ecosystem ever accept such a consensus shift?
2) Use Bitcoin for payment solutions—Lightning Network, Taproot Assets, client-side validated RGB—all fundamentally relying on Bitcoin’s UTXO model for security. This inherently limits their optimal use case to payments.
Lightning already delivers seamless micro-satoshi transfers. Taproot Assets and RGB are similar—better suited for stablecoin payment channels.
Adding DeFi or EVM-like state complexity on top of state channels or client validation means layering more complex verification logic onto the base UTXO model. This inevitably leads to states that the mainnet cannot verify, forcing reliance on off-chain consensus. Such approaches might work, but compared to pure UTXO-controlled transactions, security is inherently reduced.
In summary: how should the Bitcoin ecosystem evolve?
If strictly adhering to Bitcoin’s native security consensus, the path leads to Lightning and Taproot Assets—focused on stablecoin-based payment and consumption applications;
If allowing additional off-chain consensus beyond Bitcoin’s mainnet rules, then client-validated models like RGB open doors to complex Layer 2 smart contracts;
If Bitcoin serves only as a settlement layer with full consensus achieved off-chain, then sidechains, consortium chains, indexing chains—any system capable of independent consensus and transparent asset settlement—become viable;
And if BitVM or similar Turing-complete verification schemes actually materialize—without altering Bitcoin’s consensus and at lower cost than Ethereum smart contracts—then all of the above conclusions may need to be re-evaluated.
Ultimately, the trilemma of security, decentralization, and scalability is especially acute on Bitcoin. Perhaps the idea of a “true” Bitcoin Layer 2 is a myth. In my view, embracing orthodoxy means accepting scalability limits; breaking those limits requires abandoning claims of ultimate, universal consensus supremacy.
