Vizsafe
the decentralized crowdsourcing safety network
Vizsafe’s blockchain-enabled app provides the only solution already in use by high profile Venues, Stadiums, and Smart Cities 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.
Token of valueThis allows venue hosts to access a huge wealth of crowdsourced safety information about their venue in real time. To incentivize guests to become active participants in the process, Vizsafe has integrated its own blockchain token, SPOT.
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.
