Grandma leaned on the sofa, pointing at the three words 'blockchain' on the TV news screen, a look of confusion in her eyes: "What exactly is this thing? Just the name sounds quite scary." I was momentarily lost for words, the definitions and white papers in my head were of no use. I simply took out my phone and opened a transparent lottery application’s winning record to show her: "Grandma, imagine this, it's like the vending machine at the entrance of the community. You invest one unit of money, the system gives you a participation qualification, and the draw is completely executed by the program automatically, the whole process and results are recorded in a ledger that the whole world can see—no one can tamper with it, cheating is simply impossible." She leaned closer to the screen and looked for a long time, her fingertips gently poking at those transaction records, and finally smiled: "So that's how it is, this is indeed much more transparent than the lottery we used to have at our workplace, no one can pull any tricks." I felt a warmth in my heart—truly good technology never relies on complex jargon, but rather allows ordinary people to see its essential logic at a glance.

The electronic screen at the restaurant entrance flashed: Table 57 is still waiting. The customer sat in the waiting area, scrolling through his phone, his brow furrowed, a restless atmosphere gradually spreading. The project docking had already been going on for half an hour, and the atmosphere began to feel a bit cold. I suddenly had an idea and took out my phone: "Have you heard of that kind of transparent lottery mini-program? You can participate for just a few bucks, it's a nice way to kill time." He nodded, half in disbelief. We huddled together like two elementary school students, staring closely at the countdown seconds, watching the number of participants getting closer to the limit. The prompt 'Congratulations on winning' suddenly popped up, I had gained an asset in my account, and he suddenly burst out laughing: "This speed is a hundred times faster than our company's reimbursement process!"

The previously tense business conversation atmosphere relaxed at that moment, and the subsequent cooperation discussions went unexpectedly smoothly—sometimes, business scenarios do not require carefully crafted rhetoric, just a sincere, unguarded emotional resonance. $BTC $ETH
