This article explains in detail the different forms of information input on the chain: Ethereum can also be used for chatting?
You know, there are not only robots fighting in the dark forest and attackers in mysterious cloaks on the chain, but there are actually many little stories that are ignored by people. Blockchain can not only be used to transfer assets with rich economic value, but also can be an anonymous public chat software with "permanent preservation" function. Do you remember "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks."?
This article comes from the official blog of Etherscan, the block browser of Ethereum, which introduces in detail the different forms of information input on the chain with various interesting examples. Rhythm BlockBeats translated the original text:
On August 11, the Poly Network was hacked on an unprecedented scale, with a total of $611 million stolen. However, what is different from the past is that this hacker not only stole a huge amount of money, but also sent and received information through his own address, and had a continuous dialogue with PolyNetwork. Not only that, he even attached his own attack process in a self-questioning way The journey of the heart.
Ethereum users have always used their wallets to communicate with the world and each other in a variety of ways. We will take a closer look at these methods in this article, they are:

There are a large number of transactions in Ethereum every day. It will be extremely challenging to identify which of these transactions belong to IDM, because those transactions containing contracts may be converted into UTF-8 encoding. In this case, transaction information becomes a A pile of incomprehensible gibberish. And in those information-type transactions, the character format may be incorrect, resulting in some information still being garbled.
From the information we can identify, their uses can be divided into the following categories:
- Transaction receipts and notes
- property description (presented in JSON format)
- Crypto begging
- Advertising

Transaction receipts and bills
This information is most often presented in the form of receipts or bills. Receipt and ticket appear more frequently than any other term when searching for common terms in IDM that includes a subset of addresses.

information verification
Some addresses will use IDM for information verification, and among them, there is even an address that sends itself an IDM every day.

"Encryption" begging

The effect of the picture above: God V! Please help me! Please lend me 60 ETH! I've lost $150,000 since I entered the currency world, and I'm getting married soon. I'm from India and my dad has a heart attack and he's about to have surgery, the medical bills cost me everything and the corona has cost me my job, I know it sounds ridiculous, but please help me God!

advertising
Different from sending begging messages, some entrepreneurs will send IDMs to popular addresses in order to promote their products. One address sent spam with IDMs to over 150 other popular addresses trying to solicit sponsorships under the banner of "Trollhunters - the first tokenized 3D animated movie", but in the end the The fundraising effort was not considered a success.

byte
Not only that, but converting the data to UTF-8 encoding to make it appear in the form of bytes is also a type of non-standard IDM. To read this type of information, one needs a tool that converts the data text from byte format to string format.

verified signature
Another type of information, while using Ethereum, is not stored on-chain. Wallet users can sign messages with their private key to prove that the message came from the address it was signed from. After that, anyone else can verify the signed message with the tools on Etherscan and Mycrypto.
After verification with platform tools, Etherscan keeps a record of the signed information. While these tools were originally designed to allow contract creators to verify ownership of their contracts, they have grown in popularity as thousands of people use them for other things.
Why would a user choose to use verified signature information instead of IDM? On the one hand, this information is not tied to the receiving address, as long as you log in to the verification signature page of Etherscan, you can view the information list containing this information without navigating to other addresses. Users can get a more intuitive reading experience and no longer need to spend time converting hexadecimal to UTF-8 encoding. More importantly, this model will not incur transaction costs like using IDM.
Looking at this information, it can be found that their purpose is not the same as IDM:
- 30% of the information is used to verify account information on social media.
(Note: For those who want to add public name tags to addresses by verifying account information, Etherscan needs to see links to signed information on social accounts to verify both parties.)
- 29% of the messages were not in the Etherscan format, but in another format, used to verify address ownership.
- Only 9% of messages were written strictly using templates in Etherscan.
- Interestingly, as much as 1% of the information is used for the delivery of goods in the courier business.
In addition to the above uses, this information has the following interesting uses:
- Ask for exchange help
- Issue smart contract license
- Seeking P2P loans on Bitcointalk
- Announce the correct Twitter account for DeFi projects
- Vote on Uniswap governance
- Financial Audit Verification
- Correct wrongly sent USDT

Love letter to the effect: I gave up everything for you, I love you! I won't repeat it! Have you ever looked at me, should I continue to wait for you!
Due to its Turing completeness, Ethereum can be used not only for DeFi and NFT, but also in many ways, one of which is as a messaging. At present, this function of Ethereum has not been further explored, and the development space is still huge. It is expected that it will be able to exert greater value in the future.
