# Voken Public-Sale (STOPPED)¶

The entire Public-Sale process operates by a smart contract on Ethereum blockchain, with no other priviledged access given to any party.

Voken Public-Sale Contract is open-sourced under the GNU General Public License v3.0 and can be viewed on the github repository and etherscan.io.

## Service Value & Usage Value ANCHORING¶

• 1 Voken = 100GB client traffic, solid value base.
• 100GB is worth about $8.00 - 8.50 USD in mature IDCs and cloud service platforms, such as Amazon AWS and Google GCP. • You can spend 1 Voken to exchange 100GB traffic to use the unblocked accessible Internet, or earn Vokens by selling/sharing your idle bandwidth. ## About 7.889 billion Vokens for Sale¶ There are about 7.889 billion Vokens would released, accounting for 22.54% of the total supply. All the 7,888,866,400 Vokens for sale were stored in an open-sourced Voken Public-Sale Contract on the Ethereum blockchain, to make sure it is clear and free to check at anytime. Transaction hash 0x5400ab9dcb680641e490f60800c8df20aef033fd4a279f6bef76fbdaebcd80a6, Crypto-currency ETH will be used as the only trading medium to complete the sale. ## Dynamic Audit ETH price¶ Using ETH as the payment medium, we will adjust the Audit ETH price dynamically, according to the latest price in the trading market, in order to ensure that Voken is relatively stable against legal tender at different times during the whole sale phase.

Total sales are divided into 60,000 stages, each step of$0.00001.

In the very first phase, named RAPID-GROWTH PHASE, which is divided into 15,000 stages, each selling 100,000 Vokens, for a total of 1.5 billion Vokens.

Whenever a stage is finished, the exchange price increases by $0.00001: Stage Number Sales Volume Exchange Price Sales Amount 0 100,000 Vokens$0.00100 $100 +$0 = $100 1 100,000 Vokens$0.00101 $100 +$1 = $101 2 100,000 Vokens$0.00102 $100 +$2 = $102 7500 100,000 Vokens$0.07600 $100 +$7500 = $7,600 14999 100,000 Vokens$0.15099 $100 +$15,100 = $15,099 15000 100,000 Vokens$0.15100 $100 +$15,100 = $15,100 After the rapid-growth phase finished, the STEADY-GROWTH PHASE automatically comes (45,000 stages total),$15,100 USD for each stage, until the exchange price reaches $0.601: Stage Number Sales Volume Exchange Price Sales Amount 15001 99993.377922 Vokens$0.15101 $15100 15002 99986.756721 Vokens$0.15102 $15100 15003 99980.136397 Vokens$0.15103 $15100 37500 40159.574468 Vokens$0.37600 $15100 59999 25125.210070 Vokens$0.60099 $15100 60000 25124.792013 Vokens$0.60100 $15100 ## Per transaction¶ • Minimum: 0.1 ETH • Maximum: 100 ETH ## Gas limit¶ • Recommended: 6,000,000 • Maximum: 8,000,000 • The rest will be returned automatically • A transaction with gas limits below 3,000,001 will be automatically reverted, and about 21,290 gas miners’ fees will be exhausted. ## Bonus¶ A single transaction > 10 ETH will receive 10% bonus. ## Whitelist¶ Anyone who participate in the Voken Public-Sale (STOPPED) by using a whitelisted ETH wallet address would enjoy a gift of BUY ONE AND GET ONE MORE FREE. ## 50% - 100% of sales revenue will be used as rewards¶ We introduced whitelist and referral mechanisms in the Voken Public-Sale (STOPPED) rules.

In this sales plan, 50% - 100% of sales revenue is designed as COMMUNITY and PROMOTION TEAM REWARDS, that is about 595.13 million USD: Learn more about: Voken 2.0 Referral Program ## For example¶ If you send 20 ETH to the Voken Public-Sale Contract at the 37500th stage, and the Audit ETH price goes to$200 USD for example:

• This 20 ETH will be treated as $200 x20 ETH =$4,000 USD.
• At the 37500th stage, the exchange price is $0.37600, that is$4000 / \$0.37600 = 10638.297872 Vokens.
• A single transaction > 10 ETH will receive 10% bonus, that is 10638.297872 x 10% = 1063.829787 Vokens.
• Subtotal: 10638.297872 + 1063.829787 = 11702.667659 Vokens.

Finally, the amount is 11702.667659 + 11702.667659 = 23405.335318 Vokens.
