DAS AMA with Polygon Recap (Come and Check the Winners)

It’s a great honor for DAS to have Chinmay, Head of polyon Community, as the presenter of this AMA on 5:00PM IST, Dec.21 . Here is a recap of the AMA.

Warm-up Questions

1. Could you please introduce DAS to our community in layman’s terms? What is DAS and what can I do with it?

DAS is a cross-chain decentralized account system. DAS provides a globally unique account system with the .bit suffix. It can be used in scenes such as crypto transfers, domain name resolution, and identity authentication. DAS has strong cross-chain capabilities, supporting CKB/ETH/TRX/BSC/Polygon and any other public chain address.

When using a wallet, an operation we often use is to transfer or receive money between different accounts, and we all use a long string of addresses, such as [0x…] for BSC users, or [T…] for Tron users, as shown in the figure.

I believe that in this process, few or no one will remember the above addresses, one because it is too long and difficult to remember, the second is also unnecessary.

Then I believe there will be many friends who will think of us when we use PayPal. We just need to know each other’s email or phone number to transfer money or receive money, how convenient, right?

Unlike the centralized account system in the web 2.0 world such as phone number/email/social account, DAS has developed a decentralized account system for web 3.0 based on blockchain, and it is globally unique and cross-chain. We use a suffix ending in .bit to identify this account, and in DAS account management you can associate all your blockchain addresses, whether they are CKB/ETH/BSC or any other public chain address.

Once you have a DAS account, you can use it in any wallets that integrate DAS. let’s check out a sample picture and a video of how it works.


You could Click ‘Discover’ and search ‘DAS’ DApp or ‘da.systems’ in a wallet like TokenPocket.

2. So function-wise DAS looks like ENS, can you let us know what’s unique about DAS compared to ENS?

You can think of DAS as a cross-chain version of ENS, ENS can only be used on ethereum, DAS can be used across chains to any public chain, either EVM-compatible or non-EVM-compatible chains.

The main difference is that users can use ANY other public chain addresses (for now DAS supports ETH/TRX/BSC/Polygon address) to register, manage and own an .bit account.

DAS stores its data on the Nervos Network (CKB), but by using CKB’s rent model and capability for verifying foreign-chain transactions it mostly lets users avoid direct interaction with the CKB chain. This makes DAS more accessible, and cheaper compared with ENS.

I will share a picture to show the structure of an .bit account.

DAS is now fully open-source, and you can access our open-source repository on our GitHub at:https://github.com/DeAccountSystems/Documents

3. DAS launched in July, how is the traction so far?

Yes we had a beta launch in July and since then the growth is pretty steady, we grew from 7k accounts and 2k owners in the first month to over 45k accounts and 17k owners in the fourth month. Meantime we have integrated with 20+ wallets and dApps, which also helped a lot in the adoption of .bit.

Selected Twitter Questions

Q1( @YuanEveline ): Dear Kyle, could you please explain what are the main benefits and purposes of cross-chain decentralized accounts on blockchain? Why any Normal user or even any business should have DAS account?

A decentralized identity protocol as a foundational component of Web 3 should be highly compatible and easy to use.

The most important feature of DAS is its cross-chain capability, supporting registering with any public chain address. This is made possible by the highly scalable Nervos CKB public chain on which DAS is based. Any public chain can naturally use DAS without any modification. Now, DAS already supports registering with ETH, TRON, BSC, and Polygon addresses, and more public chains are coming. So far, no other DID has cross-chain capability except DAS.

Our goal is to bring DID to everyone. The user base of DAS will grow as the number of active crypto users grows.

When you have a DAS account, and there are many DApps that already integrate the DAS Reverse Record.

Direct any addresses to a .bit account to make your asset transfer more secure and replace the complicated address with your favorite .bit in applications.

Q2( @Him_Sze ): DAS users are increasing at a rapid rate, and polygon as one of the famous public chains, how the two through deep cooperation, so that the perfect integration of DAS domain name and polygon can be comparable to ENS and Ethereum.

DAS allows users to register and manage the DAS accounts using ANY public chain address or even email, and it’s totally decentralized. For now, you can use your ETH/TRON/BSC/Polygon address (and we are working on adding other public chains — Avalanche/BTC/Doge/Shibi, etc in the near future) to register and manage the DAS account.

This compatibility of DAS makes it the most inclusive name service, which is unmatched by ENS, Unstoppable Domains, and any other name system.

DAS is low-cost for users. ENS is the widely used name service but the users have to pay a high gas fee on registration and pay every time they want to modify the parsed record or transfer the ownership of the account. Users don’t need to worry about the gas fee when using DAS. (Below is a comparison of DAS vs ENS)

ENS is a pioneer and its recent token airdrop brought more awareness to DID in general. We all know that many crypto users buy tokens first before they learn about the product behind them, and ENS is actually helping the industry grow, as their tokens have reacquainted many users who originally had no knowledge of the field.

DAS registration and management already support payment via CKB, which is the only payment token in the trading market(https://bestdas.com ).

At the same time, with the excellent ecological incentive model of DAS, and the huge community power (including DAS DAO), I believe that the user consensus of DAS will catch up and surpass ENS in the future.

Q3( @oceansbaby_bit ): DAS supports reverse record,so does it mean that das will also support logging into blockchain projects directly through das account? When everyone has set up reverse resolution, won’t it avoid some transfer error problems?

DApps lack human-readable usernames, DAS provides usernames for users and creators

Logging in with an address is the first step, but addresses are long, hard to read, and hard to recognize. DApps lack a simple, human-readable username.

DAS provides each creator and user with their own Username, and lists displaying multiple lines of addresses will be clear and straightforward.

Reverse Record makes Secondary Verification in Blockchain — Transfers Are More Secure.

In the blockchain world, the tragedy of losing large assets due to the wrong transfer addresses happens frequently. Here is the most common example of misses.

When using Pancake or other applications, MetaMask transfers show an insufficient balance. At this point, when people withdraw tokens from the exchange to the wallet address, they tend to copy the right-hand side of MetaMask to the exchange. Then the assets are withdrawn to the contract, resulting in lost assets.

However, if we were to see alice.bit → pancake.bit at this point, I believe that this type of tragedy would not have happened.

The forward resolution allows us to transfer assets to Alice by entering a simple alice.bit, and similarly, when we transfer assets to Alice by entering 0x…24de, Apps will also show us that the address has been bound to alice.bit, which is equivalent to secondary authentication in the blockchain. DAS will effectively help to increase the correct rate of transfers.

Q4( @noneptr ): When can reverse analysis support most dapps? I noticed that there is almost no dapp support now. Does the das project have any plans?

Forward resolution means that we map a DAS account to multiple addresses. For example, alice.bit maps alice.bit to records such as ETH addresses starting with 0x…, TRX addresses starting with T…, etc.

> Forward resolution:

alice.bit → 0x4f67…1279

Reverse resolution, on the other hand, resolves an address to a record of a DAS account. Its biggest advantage is that it can transform long, hard-to-read, illegible addresses into human-readable DAS accounts.

> Reverse resolution:

0x4f67…1279 → alice.bit

TQ5Qtf…rNfxQ → alice.bit


1. Universal Cross-chain Username in DApps

DApps are the largest application of blockchain, but DApps now have two serious problems.

DApps lack human-readable usernames, DAS provides username for users and creators

Logging in with an address is the first step, but addresses are long, hard to read, and hard to recognize. DApps lack a simple, human-readable username.

DAS provides each creator and user with their own Username, and lists displaying multiple lines of addresses will be clear and straightforward.

DApps Lack Universal Username, DAS Effectively Protects Creators’ Rights

Recently, copyright issues have come to the forefront. While NFTs largely solves the problem of unlimited reproduction and ownership of digital artwork, it can still be copied and saved. Anyone can mint an NFT with the same image.

However, unlike the real-name registration system in the real world, addresses on the blockchain are extremely anonymous. Since they are difficult to identify, buyers who have not fully researched the work are often vulnerable to fraud. DAS helps to avoid such fraudulent incidents. DAS provides a globally unique name system that provides a universal username for different DApps so that buyers can identify the creator. The same creator’s address will appear as the same, human-readable .bit account in different DApps.

With the cross-chain capability, DAS can provide reverse resolution for any public chain address. All EVM Chains(ETH, BSC, Polygon…)and TRON are now supported. It also means that after setting the reverse record, you have a universal cross-chain Username in the DApp.

2. Secondary Verification in Blockchain — Transfers Are More Secure

The previous question also happens to be mentioned, so I won’t repeat the answer here.

3. More

In fact, with the powerful compatibility and extensibility of DAS, any RSA public key can be set as the reverse record of DAS, just as any RSA private key can hold and manage a DAS account. It also means that DAS can bring us a more secure and friendly experience not only in blockchain but also in other scenarios of Web 3.0 that we can’t imagine yet.

Currently, DAS DApp and BestDAS support DAS reverse record, with more applications on the way. DAS reverse record is just live, and it still takes some time for Apps to integrate.

Q5(@Yang52666 ): I think Das has more advantages than ens, but its popularity is not as high as DAS. Maybe the airdrop of ENS atmosphere improves the viscosity of users and is favored by capital institutions. Facing this situation, how should Das market itself attract capital.?What actions?

This is a very good question. As a serial entrepreneur, I very deeply share the feeling that a good project should not only have good ideas, good features, good business model, but more importantly, it should be able to traverse the bulls and bears and continue to provide the most valuable service.

DAS provides a very basic capability in the web 3.0 world, and the demand is very fresh, DAS only took 4 hours to exceed 3000 registrations on the first day of launch, which is far beyond our expectations.

Secondly, the revenue model of DAS is very simple and effective, we just charge an annual fee for each account, and the price varies according to the length of the account, for example, 5 and above are within $5 a year, 4 are $160 a year, 3 are $640 a year, we collected more than $20,000 on the day of launch, which is a very significant income for a startup team. And we believe that it will be better when we have more wallets and dApps integrations.

I believe that as long as we continue to provide good products and services, focus on user experience, and continue to develop quality partners to grow the ecosystem, we will be able to live a long and stable life!

DAS is committed to becoming the infrastructure of the crypto world, which can’t be built without the community working together and we believe a well-designed revenue sharing system can make the DAS community grow faster. We want to see every DAS community member get the corresponding rewards from contributing to the growth of DAS.

There are several roles we identified in the ecosystem and please note any organization/individual can play multiple roles at the same time.

The channel rewards, promotion rewards, and Keeper rewards are capabilities implemented at the contract level, and the rewards are billed to the corresponding roles in real-time.

DAS also has implemented invitation and channel rewards at the contract level and already partners have earned tens of thousands of dollars this way. Whether you are a community leader, a Twitter/FB/Ins KOL, or a YouTuber or TikToker, we welcome you to join us in building DAS and reap the financial rewards.

The third way we attract users is through the community (including DAS DAO). Currently, DAS has almost 10,000 community users, and we are very confident that we can reach over 300,000 community users or even more next year because our community is very open and has a lot of fun activities including prize bounty, and, as DAS DAO continues to grow, I believe it will help us attract more users as well.
