We are building EduLadder(ELADR) - Protocol

The Eladr Protocol is a decentralized, security and efficiency enhanced Web3 noSQL database powered by IPFS as the data storage layer https://ipfs.io/, and the Cardano block chain as the rewards token platform, https://cardano.org/. It provides a JSON based, IPFS layer 2 solution for data indexing and retrieval in an 'append only' file system built with open source Node.js API libraries.

The ELADR token was designed to incentivize and reward community members as a proof of contribution. Token holders are also granted access to EduLadder.com premium features as well as associated ELADR token enabled apps.

Reading a cookie using JS is as simple as creating the same. As the value of the document.cookie object is the cookie, use this string whenever you wish to access the cookie.

The document.cookie string keeps a list of name = value pairs, where each pair is separated by a semicolon. The name represents the name of a cookie and the value represents the respective cookie’s string value. For breaking the string into key and value, you can use the split() method.

Web Browsers and Servers use HTTP protocol to communicate and HTTP is a stateless protocol. But for a commercial website, it is required to maintain session information among different pages. For example, one user registration ends after completing many pages. But how to maintain users' session information across all the web pages.

In many situations, using cookies is the most efficient method of remembering and tracking preferences, purchases, commissions, and other information required for better visitor experience or site statistics.

How It Works ?
Your server sends some data to the visitor's browser in the form of a cookie. The browser may accept the cookie. If it does, it is stored as a plain text record on the visitor's hard drive. Now, when the visitor arrives at another page on your site, the browser sends the same cookie to the server for retrieval. Once retrieved, your server knows/remembers what was stored earlier.

Cookies are a plain text data record of 5 variable-length fields −

Expires − The date the cookie will expire. If this is blank, the cookie will expire when the visitor quits the browser.

Domain − The domain name of your site.

Path − The path to the directory or web page that set the cookie. This may be blank if you want to retrieve the cookie from any directory or page.

Secure − If this field contains the word "secure", then the cookie may only be retrieved with a secure server. If this field is blank, no such restriction exists.

Name=Value − Cookies are set and retrieved in the form of key-value pairs

With JavaScript, cookies can be read like this:

var x = document.cookie;

document.cookie will return all cookies in one string much like: cookie1=value; cookie2=value; cookie3=value;
