1. Satoshi Nakamoto’s paper-Bitcoin White Paper In 2008, under the overly loose credit standards in the United States, a huge bubble in housing loans triggered a series of financial crises that started in September 2008.

On Sunday, September 14, Lehman Brothers declared bankruptcy after the U.S. Federal Reserve refused to provide assistance to support its capital, and on the same day Merrill Lynch announced that it was acquired by Bank of America.

These two events marked the starting point of the financial crisis, which in turn triggered the global stock market crash and the Great Financial Recession. Many investors suffered heavy losses and made people begin to distrust the totalitarian financial system.

2. Genesis Block On January 3, 2009, the first Bitcoin block was born after the first batch of miners obtained 50 Bitcoins through mining. This also marked the official birth of the Bitcoin financial system.

Interestingly, it was several years after the advent of the Bitcoin blockchain that a hexadecimal string was discovered at line #1616 in Coinbase’s genesis block transaction encoding.

After converting this string into alphanumeric characters, you will get "sknab rof tuoliab dnoces fo knirb no rollecnahC 9002/naJ/30 semiT ehT", which in turn reads "The Times 03/Jan/2009 Chancellor on brink of second bailout for

"banks" is the date of Bitcoin's creation and the message left by Satoshi Nakamoto in the original transaction.

3. The first Bitcoin payment – ??Pizza DayLaszlo Hanyecz is a Floridian and engineer working for the online retail company GoRuck, but if you are in the currency circle, you must have heard some of his amazing deeds: Hanyecz in May 2010

On the 22nd, he used 10,000 Bitcoins (BTC) to buy two slices of pizza from Papa John's from a netizen, which is a pizza of US$25. Today, 10,000 Bitcoins are worth approximately US$40 million.

The man named Jeremy Sturdivant (online name "Jercos") was the one who originally received 10,000 Bitcoins in exchange for two slices of pizza to Hanyecz.

The importance of this transaction is that this is the first time in history that Bitcoin has been physically traded, proving that Bitcoin does have the function of price holding transmission in the real world.

4. Mt.Gox, the largest exchange hacking incident in history. On February 24, 2014, Mt.Gox was the largest Bitcoin exchange at the time.

Mark Karpeles, CEO of the exchange, announced his withdrawal from the Bitcoin Foundation in his blog. Subsequent visits to Mt. Gox will only return a blank page.

On February 28, 2014, Mt. Gox filed for bankruptcy protection with the Tokyo District Court. According to data from the bankruptcy research institution "Teikoku Databank, Ltd.", Mt. Gox's liabilities reached 6.5 billion yen. In 2013,

Revenue was 135 million yen; Imperial Information Research Company stated in a press release that Mt. Gox later discovered that 100,000 of its own Bitcoins and 750,000 user Bitcoins had been stolen.

5. The advent of Ethereum On July 30, 2015, the first Ethereum was officially launched, named Frontier.

All the Ethereum promised to early investors was successfully delivered, and developers began to weave their dreams on Ethereum.

Part II of the third version of Ethereum Metropolis—Constantinople will be launched soon (currently postponed to the middle of next year). Although the current price of Ethereum is less than 10% of this year’s high, we have witnessed in the past three years

It includes the innovations that Ethereum has brought to the world: including the Ethereum virtual machine, smart contracts, Dapps, permissioned ledger (Permissioned Ledger), etc.

Although Ethereum is facing expansion difficulties and is still waiting for technological updates, in 2017 and 2018, many underlying public chains emerged as application platforms, that is, many competitors of Ethereum, ushering in the "multi-chain era."

Currently, there are many dApp developers who are turning to other public chains due to the limitations of Ethereum's current TPS. Some people believe that the future will be a scenario of "multiple chains in parallel, each chain facing one aspect."
