DAS Public Beta is live!

We are excited to announce the first version of DAS has been developed! Before launching on mainnet, we want to work with the community to build DAS more solidly. Therefore, we are opening a one month public beta and wanted to invite you to make DAS better!
By participating in the public beta, you will have the opportunity to write data in the DAS Golden Cell and get 「DAS Golden Cell Genesis」 NFT.

Time: June 10, 2021 — July 10, 2021 (UTC+8)
Public Beta URL:

Participate in the DAS Public Beta

Go to Public Beta URL: https://da.systems/ and register a DAS account.

If the transaction ID of the account ends with 0, 1, 2, 3, 4, or 5, it means that you have the right to write data in the DAS Golden Cell. (The transaction ID can be viewed at the bottom of the account details page).

If you are eligible to write data in the DAS Golden Cell, make sure to add a special parsing record under your account before the public beta ends on July 10th, 6:00 pm UTC+8:

Type: Select “Custom Key”
Custom Key: dasgoldencelldata
Custom Value: The data (limited to text) you want to write to the DAS Golden Cell.

Make sure to fill in the “Custom Key” correctly. Incorrectly filled in will result in unreadable and unwritable data. By the end of the public beta period, the DAS team will collect the eligible data from the public test environment and write them to the DAS Golden Cell.

⚠️Please note: The data must not contain political, religious, or pornographic content. Data that does not meet the criteria will not be written.

The DAS Golden Cell

Voyager Golden Records are two records that were launched into space with the Voyager probe in 1977. The recordings contain the sounds and images of various cultures and life on earth, with a view to the discovery of highly intelligent beings in the universe.

Just like the Voyager Golden Records, the DAS Golden Cell, aka the “DAS Golden Cell” is the only special account of the DAS system and the foundation of the entire DAS system, it will be deployed during the initialization of the DAS and all accounts will be created based on it. The “DAS Golden Cell” will exist forever and the information recorded in it can never be modified. Therefore, we plan to write some information in it in order to keep it forever for people to read in the future.

These messages include:

[Part 1: Acknowledgement List], the DAS cannot be created without their work.

1. Satoshi Nakamoto

2. N****

3. E****Team

4. J****

5. Z****

[Part 2: Development Team], who designed and developed the first version of DAS.

[Part 3: Genesis Message], messages that DAS supporters want to keep forever.

The genesis message, aka written data can be any kind of content such as text, image, audio, video, file, etc. The original data must be made available to the DAS team to ensure that it does not contain political, religious, pornographic or other content.

The Hash of the data will be placed into the Merkle tree and eventually the Merkle root will be placed into the DAS Golden Cell.

The “DAS Golden Cell Genesis” NFT

The “DAS Golden Cell Genesis” NFT is a limited edition of 122 NFTs that will be released by the DAS team when launching on CKB mainnet.

Each “DAS Golden Cell Genesis” NFT is unique and represents the location of the data you have written in the DAS Golden Cell, referred to as the “Golden Cell Genesis” NFT. For the inhabitants of the future metaverse, they can find the data you left behind by using the location information recorded in this NFT.

The “DAS Golden Cell Genesis” NFT is an acknowledgement of your contribution to the DAS system. In the future, the [DAS Golden Cell Genesis] NFT will be the object of empowerment by the growing DAS system.

The “DAS Golden Cell Genesis” NFT is limited to 122 pieces and the distribution details are listed below:

  1. Allocation based on Donations — The initial deployment of the DAS will require approximately 2 million CKB, which will be a significant expense for the DAS development team. Therefore, all CKB donated to the DAS team will also be used for the initial deployment cost of the DAS.
  • [61 NFTs] — On May 17th, the DAS team distributed 61 DAS Golden Cell Token with a price of 366 CKB per token to early contributors and all proceeds went to Nervina Labs — the creator of NFT minting platform Golden Legend, as appreciation for their work in the CKB ecosystem. Each DAS Golden Cell Token holder needs to donate at least 4096 CKB to become eligible to write data into the DAS Golden Cell.
  • [up to 2 NFTs] Donate 500,000 CKB or equivalent in other digital currencies to the DAS team and become eligible to write data into the DAS Golden Cell.

2. Allocation based on contribution — You will also have a chance to win “DAS Golden Cell Genesis” NFT by participating in the DAS public beta. Rules are stated below:

  • [15 NFTs] — Invite others to sign up for a DAS account
    DAS has a built-in invitation reward system, invite others to sign up for a DAS account and you will receive 8% of their registration fee as a reward. The invitation reward is implemented at the smart contract level, so the reward is issued in CKB and is paid in real time. At the end of the DAS public beta, the first 15 people who have invited the highest number of valid accounts will become eligible to write data into the DAS Golden Cell.

How to calculate the number of valid accounts?

The number of valid accounts invited = The number of invited DAS accounts after de-duplication based on the Owner address.

A DAS account invites N DAS accounts, and n of these N DAS accounts have the same owner address. Then the number of valid accounts = N-n+1

  • [10 NFTs] — Report valid bugs to the DAS team
    If you find a bug in DAS during the public test and report it to the DAS community (WeChat group or Discord). The DAS team will review the authenticity and validity of the bug and fix it. If the number of bugs we receives is more than 10, we will randomly select 10 bugs from all bugs and the reporters of these bugs become eligible to write data into the DAS Golden Cell. The more bugs you report, the higher the probability of winning it.

Where to report bugs: (please choose one)
Chinese form: https://www.wjx.top/vj/tr6X3ZF.aspx
English form: http://dasystems.mikecrm.com/CMzL9TR

  • [10 NFTs] Help DAS to support more languages
    If you can translate the DAS website and DAS App into languages other than English and Chinese (the translation needs to be reviewed and accepted by the DAS team, you will be eligible to write data into the DAS Golden Cell.

The remaining “DAS Golden Cell Genesis” NFTs will be reserved for other contributors who made significant contributions in promoting DAS (and the contributions might not be listed above), the final right of interpretation belongs to the DAS team.

All donors and contributors will receive a “DAS Golden Cell Genesis” NFT after successfully writing data into the DAS Golden Cell.

The type of data written can be any form of content such as text, images, audio, video, files, etc. The original data still needs to be made available to the DAS team to ensure that it does not contain political, religious, pornographic, etc. It is optional to not disclose the data written.


What is the difference between the DAS public beta and the official launch?

The public test version is built on the Nervos test network. The DAS accounts registered inthe public beta are not related to the accounts that will eventually go live on the mainnet. This means that even if you register for a DAS account during the public beta, you will still need to re-register for an account when DAS goes live on the mainnet.

Do I need to pay to participate in the public beta?

No, you don’t. Anyone can participate in the public beta for free. To connect to the MetaMask wallet, please select the Goerli test network. The public test supports ETH payments and WeChat payments.

ETH payment: ETH test tokens
WeChat payment: The final actual payment amount is ¥0.01

ETH test tokens can be collected by:
1. https://goerli-faucet.slock.it/
2. https://faucet.goerli.mudit.blog/

Will the public beta data be deleted in the future?

The public beta is used in the test network and has nothing to do with the data that will eventually be online on the mainnet.
