Are Ethscriptions Decentralized? Understanding the Tech Behind Ethereum Calldata Assets
2025-05-15
Ethscriptions offer a new approach to digital ownership on Ethereum — built without smart contracts, layer-2s, or high gas fees.
Instead, they encode content directly in Ethereum's calldata. But does this minimalistic design still hold up to the ideals of decentralization?
Let’s break down the tech behind Ethscriptions and explore whether they’re as decentralized and censorship-resistant as claimed.

Key Takeaways
- Ethscriptions use Ethereum transaction calldata, avoiding the need for smart contracts.
- The system is permissionless and inherits Ethereum's decentralization.
- Unlike many NFTs, Ethscriptions store data fully on-chain at a lower cost.
- No centralized entity controls access or distribution of Ethscriptions.
- Off-chain indexers may help with discovery but are not required to verify or use the protocol.
What Are Ethscriptions?
Ethscriptions are digital artifacts encoded into Ethereum transactions using calldata — the same "notes field" often left blank when sending ETH.
Instead of deploying a smart contract or relying on metadata hosted off-chain, users embed the content directly into the blockchain at the time of transaction.
Because they don’t require executable code or complex logic, Ethscriptions are cheaper, simpler, and arguably more robust than traditional NFTs or token contracts.
They're primarily used to create lightweight NFTs, tokens, and experimental assets like inscriptions-based applications (e.g., Facet).
Are Ethscriptions Decentralized?
Yes, and here’s why:
First, Ethscriptions are native to Ethereum L1. They don’t introduce new centralized infrastructure or rely on privileged actors.
Anyone can write an Ethscription by simply submitting a properly formatted transaction. No admin keys, no contracts to shut down, no dependency on third-party dApps.
Second, the data is fully on-chain. Unlike NFTs that often point to external URLs or rely on IPFS or centralized hosts, Ethscriptions embed their data into Ethereum’s calldata. That makes them immutable and transparent by default.
Third, permissionlessness is baked into the protocol. You don't need approval to ethscribe something. There’s no registry or controller deciding what gets listed or acknowledged — the network itself is the authority.
Lastly, while many users depend on indexers to explore Ethscriptions, they aren't the source of truth. Anyone can reindex the Ethereum chain and rebuild Ethscription data independently, just like Etherscan isn’t Ethereum but a convenience layer.

Why Ethscriptions Avoid Smart Contracts
The original idea behind Ethscriptions was to sidestep the complexity and gas overhead of smart contracts. Ethereum’s calldata field is vastly cheaper and doesn't need execution. It’s essentially a passive data field — perfect for low-cost publishing and storage.
Smart contracts offer flexibility, but at a cost. They introduce attack surfaces, centralized upgrade mechanisms, and gas-heavy execution models. Ethscriptions, in contrast, are minimal, static, and require no gas beyond the basic transaction fee.
This design also removes the need to trust a contract creator. Once the Ethscription is live, it can’t be altered, paused, or manipulated.

What About Indexers?
A common concern is whether reliance on off-chain indexers introduces centralization. The answer depends on your expectations.
Indexers like Ethscriber or community dashboards are helpful for browsing and querying Ethscriptions — but they aren't essential. Any developer can run their own indexing node and verify whether the calldata in a transaction conforms to Ethscription standards.
That’s the key: Ethscriptions don't assume any indexer is "right." They rely entirely on Ethereum data. If an indexer goes down or misreports, users can always validate the underlying transactions themselves.
How Do Ethscriptions Compare to NFTs?
Ethscriptions aim to be a more decentralized and cost-efficient alternative to Ethereum NFTs.
Traditional NFTs often use smart contracts like ERC-721 or ERC-1155, and they typically point to metadata stored off-chain. That creates risk — contracts can be upgraded, and metadata can disappear.
Ethscriptions, on the other hand, store everything within the Ethereum transaction. They're simpler, harder to censor, and not tied to any specific protocol registry. This gives them greater durability and neutrality — though they lack programmability compared to NFT smart contracts.
Who Created Ethscriptions?
While similar calldata tricks have been around since 2016, the Ethscriptions protocol was formally developed by Tom Lehman and Michael Hirsch.
Inspired by Bitcoin inscriptions and early experimental messages on Ethereum, they designed Ethscriptions as a protocol that made Ethereum more usable and expressive without smart contracts.
Their goal was to make Ethereum a medium for free expression and decentralized publishing — something you could use like a digital chalkboard, not just a DeFi engine.
Final Thoughts
Ethscriptions are a fresh attempt to make Ethereum more inclusive and expressive. They embrace the base-layer ethos of decentralization while avoiding the cost and complexity of traditional smart contracts or NFTs.
While they do have limitations — no built-in logic, reliance on external viewers — they stand as a powerful example of what’s possible using only the Ethereum chain itself.
Whether you're minting art, encoding messages, or building tools on top, Ethscriptions offer a low-cost, censorship-resistant foundation that stays true to Ethereum’s original vision.
FAQs
Are Ethscriptions secure and trustless?
Yes. You don't need to trust a third-party contract. Everything is on-chain and verifiable by anyone.
Are Ethscriptions decentralized?
Absolutely. There’s no central authority controlling access or validation. They rely entirely on Ethereum’s public ledger.
Do Ethscriptions rely on indexers?
Only for convenience. Indexers help surface data but aren’t required. You can independently verify Ethscriptions by parsing the Ethereum chain.
Can anyone create an Ethscription?
Yes. Just send a transaction with calldata that follows the Ethscription format. There's no gatekeeper.
How are Ethscriptions different from NFTs?
Ethscriptions don’t use smart contracts. All data is encoded directly into calldata, making them simpler, cheaper, and more censorship-resistant — though less programmable.
