人类和微生物的关系也太神奇了!——

免疫系统的存在,不是为了杀死所有外来微生物,而是为了管理好不同的微生物,让大家和谐相处不要越界;

母乳的营养不是为了喂养婴儿,而是为了喂养双歧杆菌,然后它会为婴儿提供营养,并且帮助婴儿初步构建防疫体系;

婴儿出生前六个月,会刻意抑制免疫系统,目的是让第一批微生物入驻;

吃丰富的食物,可以丰富肠道的微生物,微生物种类越丰富越互相制衡,我们越容易保持健康。

How Does Bitcoin Mining Work?

Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.

What Is Bitcoin?

Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
