==================== Given a string that may contain lowercase English letters and a special wildcard character '*', implement a function that determines if the string is a palindrome. The wildcard character '*' can match any single character.
For example: - "racecar" is a palindrome. - "r*cecar" is a palindrome ('*' matches 'a'). - "r*cec*r" is a palindrome (both '*' match 'a'). - "hello" is not a palindrome. - "h*llo" is not a palindrome (no single character can make it a palindrome). - "a*" is a palindrome ('*' matches 'a'). - "*" is a palindrome ('*' matches itself or any single character).
Write a function is_wildcard_palindrome(text: str) -> bool that returns True if the string is a palindrome considering the wildcard, and False otherwise.

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
