BlockStamp

Blockstamp describes itself as a blockchain ecosystem supporting privacy, fairness, authentication, and freedom. According to the team, BlockStamp is a fork of Bitcoin that has been optimized for three specific use cases:

1 - Data sealing - both document storage up to 1 MB and timestamping 2 - Censorship-resistant web publishing via a blockchain domain registry 3 - Gambling edutainment - players can learn about gambling odds and test betting strategies in a provably fair platform with randomness generated via the blockchain's hashes.

BlockStamp also natively hosts the BST crypto coin and has partnered with Hprox, a peer-to-peer proxy sharing network. Users can be paid in BST for sharing their residential IP address with the network.
