01 Foreword

DAS public beta launched on June 10th, 2021(UTC+0) and has attracted many people worldwide. Over 20 days, the number of registered accounts exceeded 40,000 and the number of unique Owner addresses exceeded 30,000.

Previously, DAS has completed a seed round of funding led by HashKey and SNZ.

02 Everyone Needs a DAS Account

DAS is a practical cross-chain decentralized domain name/account system that provides a globally unique name system with a .bit suffix.

The followings are all DAS accounts:

An “alice.bit” manages all chains’ receiving addresses

When someone wants to transfer to us, we may reply:

BTC receiving address is

ETH receiving address is

TRX receiving address is

What should I do to avoid writing down the wrong addresses?

Register “alice.bit” and add all chains’ addresses to records. Anyone who transfers tokens to me, I only need to send my DAS account “alice.bit” to receive all types of digital currency.

Build a personal website in 5minutes:

How easy is it to build a cool website?

Register “alice.bit” and you will have the website “”.

All you need to do to change the content of your website is to change records of “alice.bit” and it will take effect within 5 minutes.

Best feature: Support all public chains and transferring in numerous communities

The best feature of DAS is that it supports all chains’ private key. (The current version supports private keys for ETH and TRON, with more public chains in development). This means that the DAS account you hold can be transferred in numerous blockchain communities.

As an example.

I registered “appletree.bit” with an ETH address and wanted to transfer it to my friend.

But my friend only has a TRON address, does he have to create a new ETH address to receive “appletree.bit”?

No. I can simply transfer the ownership of “appletree.bit” to his/her TRON address. Once confirmed on chain, the transfer is successful.

More features are coming…

One-click login to DApps, encrypted communication conversations and VIP identification…

03 Registration Rules

DAS uses the hot lucky box game. No one can know all open accounts. You will only know if an account is open for registration when you search the account you want in DAS App. The open rules are as follows.

5–9 digits: Randomly open (5%) in DAS Alpha launch
10+ digits: All open

How do I check if the account I want is available for registration?

Once DAS goes live, go to DAS App from the website ( and search the account you want. “Available” means the account is available for registration.

5% of the accounts with 5–9 characters will be randomly open for registration. The rule is as below:

The account name (including the .bit suffix) will be hashed using the blake2b algorithm, and the first byte of the hash result is taken as an u8 integer, and when the integer is less than or equal to 12, the account is open for registration.

Overview of All DAS accounts

As a public resource, DAS accounts should not be occupied by a few people when DAS social impact is not strong enough. For this reason, DAS accounts are open for registration on a gradual basis.

04 Pricing

Registration Cost = Annual Fee * Years + Frozen Storage Fee

Annual Fee

*Get a 5% discount when you register by filling in a inviter’s account.

Frozen storage fees

The storage fee corresponds to the storage space required to store account information on chain. DAS has been well-designed so that no matter how many records a DAS account has, only a fixed storage fee is frozen. The frozen storage fee is approximately 300 CKB per DAS account.

If the account expires and is not renewed, the frozen storage fee will be returned to the account’s owner address.

05 How to register a DAS account?
