Why do I need to lock 100.000 BitCanna coins in a Masternode?

The 100.000 BitCanna collateral is used as a type of “trust” for the network. The collateral serves to prevent Sybil attacks on the network, whereby an attacker could create numerous masternodes and interfere with network operations. Nodes with so called ‘skin in the game’ are therefore less likely to act maliciously. The more Masternodes that are active in the network, the higher the cost of such an attack.
