On-Chain Love Letter: Written for You, Forever
The first time Lin Wan met Chen Yu was in a trading group on Binance.
Back then, Bitcoin had just broken the $110,000 mark, and the whole group was celebrating. Someone posted a screenshot of their profits. Someone shouted about charging toward a million. Only Chen Yu sent a single line: "With it up so much, have you ever thought about what you should leave behind for the people you care about?"
Lin Wan stared at that sentence for a long time. She was a programmer, writing smart contracts, spending every day dealing with code—rarely moved by a single line of words. But that night, for reasons she couldn’t explain, she added Chen Yu on WeChat.
Chen Yu was a miner. In a small town in Northwest China, he ran a modest mining operation. He told her he didn’t understand DeFi or NFTs—he only knew that the coins he mined would be stored in a cold wallet, and when the market was good, he’d sell some to send money back to his mother.
"Then why did you ask that question?" Lin Wan asked.
"Because my mom was hospitalized last year. I almost couldn’t come up with the money." Chen Yu said, "How much the coins go up has nothing to do with me. What I want is for the people around me to be well."
Lin Wan didn’t say anything after that, but she began chatting with Chen Yu every day. She told him about the wonders of the on-chain world—how smart contracts automatically execute promises, how the data on a blockchain could never be tampered with. Chen Yu listened seriously, and now and then asked very simple questions, like: "What if I write a sentence there—does it mean I can never delete it in my lifetime?"
"Yes. It’s there forever." Lin Wan said.
After a while, Chen Yu was silent, then said: "Can you help me write a love letter? Put it on the chain."
Lin Wan’s heartbeat skipped.
She spent three days writing a smart contract. The contract was simple—only one thing: to record a piece of text permanently on the blockchain. She chose Ethereum’s mainnet, because the Gas fees were expensive but it was the safest. In her code, she checked every single byte again and again, like she was handling the most important work of her life.
On deployment day, Chen Yu sent her the words he wanted to say.
Lin Wan opened the message, and her tears fell immediately.
He wrote: "Lin Wan, I don’t understand anything about blockchain, but I know this thing can’t be deleted. Just like my feelings for you—they can’t be deleted, can’t be changed, and no one can take them away. I’m not very good at saying sweet words, but I want you to know: every line of code you write, I may not understand, but the way you smile—I recognize it at a glance. This letter is on the chain. When we grow old, when Bitcoin reaches a million, when this world keeps changing and changing, it will still be there. Like I’m still by your side.
Lin Wan put these words into the contract—deploy, sign, broadcast.
The moment the transaction was confirmed, the hash appeared on the screen. From that moment on, a love story entered the genetic code of the blockchain—immutable, undeletable, irreversible.
Chen Yu sent another message: "Did it work?"
"It worked." Lin Wan smiled through her tears. "It’s there forever."
Later, someone asked Lin Wan why a girl who wrote smart contracts fell in love with a miner.
She said, because in this world, some people use diamonds to propose, and some use roses to confess. But Chen Yu told her in the dumbest yet most honest way: I want the promise I give you—like the blockchain—once written, lasts a lifetime.
Nowadays, Bitcoin has already risen to $110,000. MOVR calmly fluctuates around $3.00, and ALICE has climbed from 0.16 to 0.206. The market rises and falls, but every time Lin Wan opens that contract address, seeing those words still lying there, quiet and untouched on the chain, she feels that everything was worth it.
Some loves are like candlestick charts—up, down, with bull markets and bear markets.
But some loves are like blockchains—write them down, and they’re eternal.
