Reverse Record Comes!

Introduction

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

Applications

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 username, 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 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

In the blockchain world, the tragedy of losing large assets due to wrong transfer address 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 token 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.

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 blockchain. DAS will effectively help to increase the correct rate of transfers.

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.

Guide

When you set the reverse record, the relevant information needs to be stored on the blockchain, and it requires 201 CKB of storage space. So please make sure your balance is greater than 201 CKB before setting a reverse record.

Start

Log in DAS Registrar and click on “Reverse Record”, and then set a DAS account.

The reverse record can be set to any DAS account. To ensure the accuracy of the reverse record, any of the following conditions must be met for the reverse record to be valid.

  1. Your address is the Owner / Manager of the DAS account.
  2. Your address is in the records of the DAS account.

For example, set the reverse record of the ETH address 0x4f67…1279 to alice.bit. This will take effect as long as any of the following conditions is met.

  1. The ETH address 0x4f67…1279 is the Owner / Manager of the DAS account.
  2. The ETH address 0x4f67…1279 is in the record of the DAS account.

Reasons for failure

If your reverse record is invalid, please check the following reasons one by one.

  1. the DAS account has been sold and you are not the Owner / Manager of the DAS account.
  2. the record of the DAS account has been changed and your address is not in the forward resolving record of that DAS account.
  3. The Owner permission of the DAS account is transferred, the resolution record is cleared, and your address is not in the records of the DAS account.

The reverse record is valid only if any of the following conditions is met.

  1. Your address is the Owner / Manager of the DAS account.
  2. Your address is in the records of the DAS account.

FAQ

Why do I need to freeze 201 CKB to set a reverse record?

When you set the reverse record, the relevant information needs to be stored on the blockchain and 201 CKB of storage space is required to store the data. When you delete the reverse record, 201 CKB will be automatically returned to your balance. There is no cost to edit the reverse record.

Can I set more than one reverse record for one address?

Currently only one reverse record can be set for an address.

If I set alice.bit as the reverse record of my address, will my reverse record be cleared when the alice.bit account expires?

Your reverse record will be invalid, but it will not be cleared. When alice.bit expires, its records will be cleared. You can delete the reverse record at any time and at the same time 201 CKB will automatically be returned to your balance.

If the DAS account I set is sold or transferred to someone else, will my reverse record be cleared?

Your reverse record will be invalid, but it will not be cleared. When the DAS account is sold or its owner permission is transferred, its records will be cleared. You can delete the reverse record at any time, and at the same time 201 CKB will be automatically returned to your balance.

Can I set someone else’s DAS account as my reverse record?

Yes. Any of the following conditions must be met for the reverse record to be valid.

  1. Your address is the Owner / Manager of the DAS account.
  2. Your address is in the records of the DAS account.

Can I set the reverse records of my multiple addresses to the same DAS account?

Yes. It will work as long as the reverse record for each address meets one of the following conditions.

  1. Your address is the Owner / Manager of the DAS account.
  2. Your address is in the records of the DAS account.

What Apps are integrated with DAS reverse record now?

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.
