CIAS is the first inscription project on Celestia, with a marketplace and a launchpad. On 17th Dec 2023, CIAS was launched and everyone can mint 10,000 CIAS in one transaction on Celestia mainnet. There are more than 110k addresses joined the mint and used more than $1.5M as gas fee from more than 3M transactions.

Inscriptions starts from Bitcoin, BRC-20 allow users to implement tokens on Bitcoin, while CIAS, inspired by BRC-20, writes a piece of JSON to memo field in base64 format thus implements the ability to create inscription tokens on Celestia L1.

It sounds great, isn't it? Deploying a new type of asset on a blockchain without execution environment. But the presence of inscriptions leads to some problems and is not aligned with Celestia's vision.

Celestia allows rollups to put data into the L1 blockchain by storing it in a blob and sending a transaction MsgPayForBlobs, which has a namespace inside, this means that each rollup can download and validate only the blob of its own namespace without having to download and validate all blob data on L1.

However, Memo does not have namespaces, which means that all nodes of all rollups have to download the data of all inscriptions, but these rollups have no relationship with the downloaded inscriptions. In the long run if there is more and more inscription-related activity on Celestia, it will become more and more redundant for rollups using it.

CIP-15

As a result, CIP-15 came out, the main purpose is to discourage memo usage and to reduce the possibility of making Celestia redundant. The CIAS team joined the discussion with Celestia and agree on the point that ‘Celestia was designed to support the publication of arbitrary data but the memo field is not the ideal mechanism to publish such data'. CIAS believes that moving Inscriptions from memo to blob is a much better solution for Inscriptions, and will also be working with the Celestia team to continue to discuss and push for CIP-15.

What is sovereign rollup?

Sovereign rollups are an idea that emerged from Celestia exploring new blockchain designs.

A sovereign rollup is a type of blockchain that publishes its transactions to another blockchain, typically for ordering and data availability, but handles its own settlement.

In the context of the modular stack, sovereign rollups are responsible for execution and settlement, while the DA layer handles consensus and data availability.

Combined with the use case of inscriptions, we find that inscriptions themselves are basically just sovereign rollups, simply posting data onto the blockchain, with settlement and execution via indexers.

If CIAS use blob on Celesita for storing transactions of the sovereign rollup，all data will be stored with namespace, which will not result in redundancy, and we find that this will bring a new paradigm to the whole world of inscriptions.

What does sovereign rollup mean for CIAS?

Which modular architecture powered by Rollkit, the inscription rollup can become:

• Lower cost: By taking Celestia as DA and consensus layer, on which CIAS batch transactions and store them in blobs, in this way we can reduce the cost of storing transaction data by 99%, compared to directly using Celestia L1.

• Faster confirmation: By having a built-in indexer and shortening block time, we can make the transaction initiation and indexing of inscriptions faster.

• More decentralized: Thanks to the built-in indexer, and with Celestia's DAS design we can allow more users to run our nodes, at a lower cost. More nodes secure the inscription rollup.

• A rollup designed specifically for inscriptions, not inscriptions as an appendage of the chain: inscriptions are appendages of the chain from birth, first we have a chain, and inscriptions were limited by the chain, losing the potential to scale. This rollup, however, was designed with the needs of the inscription world in mind, so all of its subsequent upgrades revolve around the inscription itself, and will bring a new paradigm to the inscription world.

The future of CIAS

The sovereign rollup will be officially launched after rebranding, and users will be able to enter the brand-new inscription world:

• Inscriptions from all blockchains can onboard, enjoying super low gas fee and faster confirmations. Inscriptions that bridged to the rollup will not be turned into tokens (unlike many other solutions), the inscriptions will keep their original content and the data will be stored in a blob (which means that even if the rollup ceases to exist, the data will not be lost and the assets will be very safe). Eg., You can trade Bitcoin inscriptions on the rollup with 0.1% gas fee compared to original.

• A fixed portion of the gas fee generated on rollup will get into the Inscription Developer Incentive Pool, which means that even with a completely free inscription project, the team will be able to earn a long-term sustainable income to support the long-term build.

• The built-in indexer not only solves the problem of centralized problem in the Inscription space today, but all the teams on it don't need to duplicatly building their own indexer to get a high-performance indexer for Inscription.

• With arbitrary bridges, all inscriptions on our rollup, whether NFT or token, have the potential to interact with protocols on other blockchains. As an example, an fully on-chain game on Starknet could read the weapon NFT directly on the CIAS Marketplace and use it on Starknet.

• And...BUILD WHATEVER on inscriptions

Problems with Inscription Airdrops

Unlike the airdrop on chains with virtual machine, where the user collects inscriptions by interacting with the smart contracts; the inscription itself is just a piece of data recorded in the transaction, plus the indexer to implement the minting, transferring, etc. of the inscription. It cannot achieve the function of airdrop by predefining some simple operations (such as transfer/mint/deploy, etc.). To implement the functionality of airdrops, and at the same time ensure that any indexer can read the data, the airdrop's information must be on-chain: know how many airdrops are available to a certain address on a certain chain.

There are two common ways to collect them:

1. by creating a new OP: Claim, the users can send a transaction with the inscription name, protocol and the claim operation, the indexer then validate the transaction, knowing whether this address can claim certain amount. But this way is too costly for users who only have a small number of airdrops.

2. Through transferring by team, the team transfers the corresponding quantity to each address to implement the airdrop. But gas fee will be too high for teams to afford. CIAS created a third way based on Celestia's powerful capabilities.

Celestia's Capabilities

• Bundling Transactions in Blobs: Celestia allows multiple transaction data to be packaged into a blob and submitted to the network via PayForBlobs transactions. These transactions include the sender's identity, stored data, size, namespace, and signature. Once confirmed and included in a block, the blob's data is securely stored in the Celestia network.

• Distributed Storage and Access: Using blobs, data can be stored on the Celestia network, accessible and shareable through its distributed storage and retrieval mechanisms.

CIAS Solution

1. Publish merkle root of addresses' balances at a Specific Block:
   ◾️ Store the merkle root of balance table corresponding to Block 381642 in a blob.
   ◾️ Send a PayForBlobs transaction

2. Record Metamask addresses and corresponding airdrops:
   ◾️ Allow users to submit their Metamask and Celestia addresses within a certain time, linking the airdrop to the Metamask address.

3. Announce Metamask Addresses and Corresponding Airdrops:
   ◾️ Store the relationship between Celestia's address and evm address in a blob.
   ◾️ Send a PayForBlobs transaction

4. Update Indexer and publish indexing rules:
   ◾️ The indexer reads values from the API and includes them in the user's balance.

Advantages of This Approach

• Zero Gas Cost: The inscription airdrop method is cost effective both for users and projects.

• Multi-Chain Compatibility: The airdrop can be implemented across multiple blockchain networks.

• Indexed and Accessible: By leveraging Celestia's storage capabilities and external indexing services, the airdrop data becomes easily accessible and queryable for every users who runs a indexer.

• Scalable and Flexible: This method can be scaled up to accommodate a large number of users and can be adapted for different blockchain environments.
  This innovative approach to inscription airdrops, utilizing Celestia's unique capabilities, represents a significant step forward in the efficiency and accessibility of inscription airdrops.
