"Love on the Blockchain"
In the vast universe of the blockchain, there are two nodes, one is called "Coder Li" and the other is called "Programmer Zhang". They convey subtle emotions through countless transaction data every day. One day, Li decided to confess to Zhang using a smart contract: "If you accept, please leave the first six digits of your private key on this block." Zhang smiled slightly, replied with a carefully designed hash value, and said: "Unlock it, and you will find my answer." After three days and three nights of calculation, Li finally found the secret message corresponding to the hash value: "I am willing to forge a love relationship with you on the chain." From then on, they wove their love code on the blockchain, allowing every block to witness their sweetness.
