Ethscriptions: A New Era of Blockchain-Based Content Storage and Ownership

Ethscriptions: A New Era of Blockchain-Based Content Storage and Ownership

On Saturday, developer Tom Lehman made headlines with the launch of the Ethscriptions protocol, a revolutionary development in the realm of blockchain technology. Co-founder of the experimental NFT platform Capsule 21, Lehman, who goes by the pseudonym Middlemarch, described the protocol's debut as a "huge success." Ethscriptions garnered significant attention, with nearly 30,000 creations finding their home on the Ethereum blockchain in less than 18 hours.

Understanding Ethscriptions

At its core, the Ethscriptions protocol introduces a groundbreaking approach to embedding fully on-chain arbitrary data on the Ethereum network. While the protocol currently supports image-based "ethscriptions" of approximately 90KB in size, it remains inclusive of other data types, including text. However, Lehman cautioned users about the potential risks associated with ethscribing identical content at a higher frequency.

Distinguishing Ethscriptions from NFTs

Unlike traditional non-fungible tokens (NFTs), which primarily serve as proof of ownership and provenance for digital files stored externally, Ethscriptions leverage Ethereum's smart contracts to host the entire asset on the blockchain. By utilizing Ethereum's "calldata" instead of contract storage, Ethscriptions capitalize on encoded parameters sent to smart contracts through the Ethereum Virtual Machine (EVM). Each calldata piece is 32 bytes long (64 characters), and by reinterpreting existing calldata as hex data, users can create new non-fungible assets directly on the Ethereum blockchain.

The Inner Workings of Ethscriptions

To create an Ethscription, users convert URI data (Uniform Resource Identifier) into hex format using tools like hexhero. Successful Ethereum transactions automatically generate Ethscriptions by default. To transfer ownership of an Ethscription, users simply send a 0 ETH transaction containing the hex data to the desired recipient. This reshuffling of code effectively creates a new non-fungible asset class that does not rely on centralized storage solutions. However, the current limitation of Ethscriptions is their file size, capped at approximately 90KB.

The Significance of Ethscriptions

The emergence of Ethscriptions represents a significant milestone in blockchain technology, especially within the context of NFTs. While NFTs often rely on centralized platforms for storage, including their associated metadata, Ethscriptions eliminate this dependency by utilizing decentralized blockchains. This decentralized approach ensures that the content and metadata remain intact and discoverable, even if centralized platforms experience data loss or disruption. Furthermore, Ethscriptions benefit from the same level of security provided by miners and validators on the Ethereum network, adding an extra layer of trust and integrity.


With the launch of the Ethscriptions protocol, developer Tom Lehman has pushed the boundaries of blockchain technology and expanded the possibilities for content storage and ownership. They provide a decentralized solution for hosting digital assets entirely on the Ethereum blockchain, enhancing security and preserving data integrity. While Ethscriptions are currently limited to a file size of approximately 90KB, their potential to revolutionize the NFT landscape and offer a viable alternative to centralized storage solutions cannot be overlooked. As the protocol continues to evolve, it may unlock new avenues for creative expression and redefine the way we perceive and interact with digital assets in the future.
