What transpired over the past month with regards to multisignature transactions is a true testament to what the Steem community can do if we work together towards a common goal. We now have four great guides on how to use multisignature transactions on Steem!!
For those of you who are just interested in getting the guides, you can scroll down to the bottom of the post. For the rest of you, please read on :)
Multisignature transactions are a security feature that requires a transaction to be signed by multiple parties (each with their own key) before the transaction is considered valid. They are an extremely useful security feature that provide support for a lot of beneficial things.
A lot of investors will consider multisignature transactions a requirement in order to purchase and hold a coin. Many developers can also use multisignature transactions to add additional layers of security to their applications and tools. There are even some creative ways they can be used to design fancy features within applications.
The Steem blockchain has always supported multisignature transactions, although they have been extremely underutilized due to lack of proper tooling and guides.
About a month ago I started talking to other witnesses, developers, and stakeholders about the possibility for offering a bounty to incentivize people in the community to help solve the problem and create better tooling and guides.
I was planning to offer 100 STEEM for a bounty to create a multisignature transaction guide that would give the community the information they need to properly use multisignature transactions. I was amazed to see how many other people quickly jumped in and offered to pitch in 100 STEEM of their own to add to the bounty!
Within a few weeks, we had a total of 1,500 STEEM added to the bounty - thanks to all our contributors: 
Five days ago we officially launched the 1,500 STEEM Bounty to create a multisignature transaction guide. I was blown away by the results!! (Details below.)
There was a reason that we all chipped in 100 STEEM to make this a 1,500 STEEM bounty - the problem we were trying to solve was hard! This is something that had not been addressed in years, and I had spoken to several people who had tried.
When we put together the bounty, we were unsure if we were even going to get a successful submission. We put in a clause to the rules that: If no valid submissions have been received by 23:59 (UTC) on March 31, 2019 then the bounty will be void/canceled - because we weren't even sure if 1,500 STEEM would be enough to motivate someone to solve the problem.
It turns out it was! In fact, within a few hours - we had MULTIPLE PEOPLE who had solved it!!
Even though it was very unexpected to have multiple submissions so quickly, we did have terms on how to deal with it. The terms stated that If there are multiple submissions, they will be evaluated in the order that they are received. The first submission to receive 12/15 approval will be the winner of the bounty.
Congratulations
All four submissions that we received for the bounty contest used the beem library, which

The terms of the bounty state that each of the 15 contributors will send their STEEM individually, so the winners should be receiving their awards from each of us over the next few days.
Here are the four guides that we now have as a result of the bounty:

Now with all the infrastructure in place, the developer community should have what they need to start using multisignature transactions to their full advantage!
We already have one dev who created a multisignature transaction app :) You can check it out here: msteem - Multisignature transaction app
I am constantly impressed by the amazing things that our community does. The results of this bounty are no exception. Everyone involved helped to chip in and make this a success, and the results speak for themselves. We now have great documentation and tools to support multisignature transactions =)
Great job everyone!!!
