After Bitshare and Steem, Dan Larimer create the EOS, like a operating system in the world of blockchain.

"The EOS.IO software introduces a new blockchain architecture designed to enable vertical and horizontal scaling of decentralized applications. This is achieved by creating an operating system-like construct upon which applications can be built. The software provides accounts, authentication, databases, asynchronous communication and the scheduling of applications across hundreds of CPU cores or clusters. The resulting technology is a blockchain architecture that scales to millions of transactions per second, eliminates user fees, and allows for quick and easy deployment of decentralized applications. "

The EOS Token distribution will take place over 341 days starting on June 26, 2017 at 13:00 UTC. 1,000,000,000 (one billion) EOS ERC-20 compatible Tokens (“EOS Tokens”) will be distributed according to the schedule below:

200,000,000 two hundred million
distributed during a 5 day period beginning on June 26, 2017 at 13:00 UTC and ending on July 1, 2017 at 12:59:59 UTC.

700,000,000 seven hundred million
split evenly into 350 consecutive 23 hour periods of 2,000,000 EOS tokens each beginning on July 1, 2017 at 13:00:00 UTC.

100,000,000 one hundred million
will be reserved for block.one and cannot be traded or transferred on the Ethereum network.

But there is a new rule appeared.

At the end of the 5 day period and at the end of each 23 hour period referred to above, a set number of EOS Tokens will be distributed pro rata amongst all authorized purchasers, based on the total ETH contributed during those periods, respectively, as follows:

Number of EOS Tokens distributed to an authorized purchaser = a*(b/c)

a = Total ETH contributed by an authorized purchaser during the period.
b = Total number of EOS Tokens available for distribution in the period.
c = Total ETH contributed by all authorized purchasers during the period.

That means in 120-hour period, more people join, fewer EOS everyone will get, have to say, EOS come up with a new and effetive method to defend the crazy of crowd.

But, in the first 5 days, there is no this rule, so, be ready and be crazy!
