Multichain Web3 Advertisements, Buy & Sell

How does W3AD work?
99% of amount spent on your advertisement space goes directly to you automatically the instant the replacement is made.
(The remaining 1% is kept in the contract and later it is used for development/hosting/legal/promotion/etc costs.)
As soon as the replacement transaction is confirmed, the advertisement is “locked” (cannot be replaced) for 24 hours.
After 24 hours, the AD “unlocks” (can be replaced) but to replace it immediately after it unlocks, it will cost you the amount of the previous replacement multiplied by 30.
This is done to discourage replacement soon after someone else changes the AD.
After the AD unlocks, the CTR (or Cost To Replace) will fall by the second and by 48 hours, the CTR will be the amount of the previous replacement multiplied by 29.
At 72 hours, the CTR will be the amount of the previous replacement multiplied by 28.
At 96 hours, the CTR will be the amount of the previous replacement multiplied by 27 and so on until the 31st day.
On the end of the 31st day, the CTR will be the same as the amount of the previous replacement (multiplied by 1).
On the 32nd day, the CTR will be the amount of the previous replacement divisible by 2.
On the 33nd day, the CTR will be the amount of the previous replacement divisible by 3.
On the 34nd day, the CTR will be the amount of the previous replacement divisible by 4 and so on (forever).
This is done to encourage replacement of the AD after 31 days.
The lowest the CTR can get is the amount of gas used for the next replacement.
THERE IS NO GUARANTEE that the advertiser will not add a filter or modify the advertisement.
YOU ARE TRUSTING THE ADVERTISING DAPP/WEBSITE TO HOST AND DISPLAY YOUR AD.
(Data in the blockchain remains the same but an advertiser may choose to modify the AD before it is displayed. For example to remove adult words.)
After you click on “Your Ad Here”, you should verify that the AD displayed on “W3AD.app” matches the AD in the advertiser’s Dapp/website.
The advertisement itself contains 2 lines of text and is 36 characters maximum per line.
The following characters are allowed.
abcdefghijklmnopqrstuvxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789
!”#$%&'()*+,-./:;<=>?@[\]^_`{|}~
The text is stored on the blockchain as a number and the characters are limited to save memory/gas.
It is recommended to set a starting minimum and an initial AD for two reasons.
This will prevent a blank space and prevents someone from taking your AD space for a very low amount.
When you set an AD on your own address, the amount you send comes back to you minus one percent.
For example if you want a starting minimum of 3, you would use 0.1 as the amount. (3 / 30 = 0.1)
When you use 0.1 as the amount for your own address, 0.099 will be returned to you. (0.1 – 1% of itself = 0.099)
Remember that all AD changes are locked for 24 hours.
Developers, be careful when using the AD lines for anything other than plain text.
(If you use one of the lines to hold a link, then you are allowing anyone to change that link.)
Just like blockchain transactions cannot be reversed, once you replace an AD it cannot be reversed.
