Check out this blockchain enabled solution for rewarding public contribution to safety...
https://www.vizsafe.com/blockchainVenues have dedicated employees and security teams to deal with such issues, but those who are very best placed to notice anything amiss include the thousands of visitors themselves. The Crowd is a fantastic, but untapped, resource. However, the reality is that in many cases, visitors will overlook a problem for want of a simple but universal process to report it to the appropriate body and the lack of immediate incentive to take the time and effort to do so.
Vizsafe’s blockchain-enabled app provides the only solution to this by allowing any user to upload safety reports on its Geoaware™ Services Platform. Users submit images and videos of any issues they encounter, which are automatically timestamped and geo-tagged, shared with the appropriate authority and stored on Vizsafe’s servers. Meanwhile, hashes of this information are uploaded to the Ethereum blockchain to ensure that there is a permanent, tamper-proof record.
SPOT is the internal reward system of the Vizsafe ecosystem. When users report an issue, a smart contract is created in the Ethereum blockchain that places a value on the information they provide. Once the issue has been addressed by security or an event employee, it is resolved on the Vizsafe platform using the same app. At that point, the person who reported it receives their reward in SPOT tokens.
