Inscriptions have rapidly evolved from a niche concept into a significant trend within the blockchain space. Initially popularized by Bitcoin’s Ordinals protocol, the technology has expanded across multiple blockchains, bringing innovation, new opportunities, and challenges. This article explores the current landscape of inscription protocols, compares their features, and evaluates their potential for future growth.
Understanding the Inscription Market
Market Overview
The launch of the Bitcoin Ordinals protocol in January 2023 marked a turning point for blockchain-based digital artifacts. The introduction of BRC-20 tokens enabled fair launches, allowing users to mint tokens without pre-sales or institutional advantages. This model, often referred to as "the people’s market," attracted widespread participation. Tokens like ORDI saw astronomical rises—from a $1 mint cost to over $20,000 on major exchanges.
This surge in interest led to increased network activity, pushing Bitcoin transaction fees to multi-year highs. The trend, often called "Bitcoin Summer," wasn’t limited to Bitcoin. Other proof-of-work (PoW) chains and Ethereum-based solutions also embraced inscription protocols.
Key Data Insights
Bitcoin’s transaction fees saw notable spikes in May–June and November 2023, reflecting heightened activity due to inscription minting and trading. Despite fluctuations, the number of inscriptions minted has remained consistently high, demonstrating sustained interest.
Inscription Protocols by Blockchain
Bitcoin-Based Protocols
Ordinals and BRC-20
The Ordinals protocol, created by Casey Rodarmor, allows users to inscribe data onto individual satoshis. BRC-20, an experimental standard built on Ordinals, enables token creation through inscribed text. While innovative, BRC-20 has limitations, including a four-character token naming constraint and vulnerability to front-running during minting. It also contributes to blockchain bloat, as initial mint inscriptions become obsolete after token transfers.
Atomicals Protocol
Atomicals introduces ARC-20, which uses individual satoshis to represent tokens and allows longer token names. A unique feature, Realms, enables users to claim text-based domains with governance and utility potential, including payment addresses and decentralized identity (DID) applications. However, the ecosystem is still immature, with limited wallet and marketplace support.
Pipe Protocol
Inspired by Casey Rodarmor’s Rune concept, Pipe offers a UTXO-based method for token issuance. Unlike BRC-20, Pipe stores token data within transaction scripts, improving efficiency. Although it gained quick traction, broader Bitcoin community acceptance remains uncertain.
RGB Protocol
RGB leverages Bitcoin and the Lightning Network for scalable, low-cost smart contracts. By storing state proofs on-chain and processing computations off-chain, it combines Bitcoin’s security with high throughput. However, its complexity has slowed adoption. Major players like Tether have expressed interest in deploying assets on RGB. Wallets like Bitmask already support RGB-20 and RGB-21 assets, and projects like Bitlight Labs are developing decentralized exchanges (DEX) for the ecosystem.
Other PoW Chains
Dogecoin
DRC-20, an Ordinals-like protocol on Dogecoin, benefits from low fees and the chain’s meme-friendly culture. Its simplicity and affordability have attracted a dedicated user base.
Litecoin
LTC-20, another Ordinals derivative, has gained official endorsement from Litecoin creators. Despite early technical issues, it has developed a robust infrastructure, including markets like Unilit and wallets like Litescribe. The first LTC-20 token, LITE, is already listed on exchanges.
Ethereum and EVM Chains
Ethscriptions
Ethscriptions uses transaction calldata to inscribe information onto Ethereum, reducing gas costs compared to traditional smart contracts. The first token, ETHS, achieved significant returns for early minters. The protocol aims to support scalable, secure applications through its Ethscriptions Virtual Machine (ESC VM). However, token divisibility remains a hurdle, though platforms like FacetSwap are working on solutions.
EVM.ink
EVM.ink extends the Ethscriptions standard to other EVM-compatible chains, enabling inscriptions on networks like Polygon and Avalanche. Tokens like POLS and AVAL have demonstrated strong user adoption due to low minting costs and high potential returns.
Solana Inscriptions
SPL-20
Solana’s inscription standard, SPL-20, uses NFTs to represent inscriptions, with metadata determining their validity. While early tokens like SOLS saw impressive secondary market activity, the lack of native divisibility limits their utility. Development is ongoing, with platforms like Libreplex and Tensor advancing infrastructure.
Comparative Analysis
Protocol Comparison
Key factors like transaction costs, divisibility, scalability, and user base vary significantly across protocols:
- Fees: RGB offers near-zero costs via Lightning, while BRC-20 and Ethscriptions balance cost and functionality.
- Divisibility: Most new protocols are still developing fractional ownership features.
- Scalability: RGB and Ethscriptions lead with smart contract support, while SPL-20 and BRC-20 are more limited.
- Users: EVM-based inscriptions attract the most users due to low barriers to entry.
Token Data Overview
Major inscription tokens like ORDI and SATS dominate market capitalization, but newer tokens are gaining traction. User distribution remains concentrated, with some protocols still in early development.
Innovations and Risks
Inscriptions enable fair launches and decentralized token distribution. Technological advancements like Taproot and Schnorr signatures have expanded possibilities. However, risks include scams, fraudulent launchpads, and technical vulnerabilities. Users should exercise caution and conduct thorough research before participating.
The Future of Inscriptions
Market Predictions
The inscription market has surpassed early growth estimates. With total inscriptions exceeding 33 million and leading tokens reaching multi-billion dollar valuations, the sector is poised for further expansion. Institutional interest and improved infrastructure could drive even greater adoption.
Product Development
Wallet and trading infrastructure is rapidly evolving. UniSat’s open-source tools have become a foundation for many platforms, and the introduction of BRC-20 swaps hints at a future where Bitcoin DeFi rivals Ethereum’s ecosystem. Enhanced APIs will enable more developer innovation, including automated trading tools and market analytics.
Ecosystem Expansion
Beyond memes, inscriptions are enabling new use cases like decentralized exchanges, lending, and identity management. Bitcoin Layer-2 solutions like BEVM aim to combine Bitcoin’s security with EVM compatibility, though challenges around decentralization and security remain.

Frequently Asked Questions
What are blockchain inscriptions?
Inscriptions involve embedding data directly into a blockchain transaction, often using protocols like Bitcoin Ordinals or Ethscriptions. They can represent tokens, NFTs, or other digital assets.
How do inscription protocols differ?
Protocols vary in functionality, cost, and compatibility. Bitcoin-based inscriptions often prioritize security, while EVM-based solutions focus on affordability and flexibility.
What is fair launch in inscriptions?
Fair launch allows equal participation in token minting without pre-sales or institutional advantages. It promotes decentralization and broad distribution.
Are inscriptions secure?
While generally secure, inscriptions can be exposed to risks like front-running, smart contract bugs, or fraudulent projects. Always verify protocols and platforms before use.
Can inscriptions be traded like regular tokens?
Yes, but divisibility varies. Some protocols support fractional trading, while others require full-unit transactions. Marketplaces and DEXs are emerging to improve liquidity.
