Hi guys, today I will teach you about a Witness on Steemit

What is a Witness?

Witnesses are the elected leaders of the community. They are ambassadors for the project, and many of them work on things to improve the value of the platform.

Witnesses are tasked with validating and producing the blocks for the blockchain, which ensures everything in the network operates smoothly and correctly. Every three seconds one of the witnesses assemble all of the transactions that have occurred (such as posts, comments, votes, STEEM/SBD transfers) into a "block" and then they store all that information in the distributed database network called the "blockchain".

Witnesses are also responsible for maintaining an accurate and up-to-date price feed, as well as deciding on several important blockchain parameters. Witnesses control the cost for websites like Steemit.com to create a new account, and decide how much interest to pay for holding SBD. Many witnesses also host a public 'seed' node that other witnesses and the rest of the community can use to interact with the blockchain.
