On the EDC blockchain platform, the hybrid LPoS algorithm (Leased Proof-of-Stake), i.e, leased proof of ownership interest, works. This consensus mechanism has its significant advantages: for example, it attracts all users, regardless of their stack, to work on protecting and securing the network, and distributes the reward fairly, as each participant receives their share in proportion to the contribution. This is an excellent opportunity even for owners of a small number of coins to get bonuses. The essence of the algorithm is that owners of smaller amounts of cryptocurrency rent their coins to full-fledged nodes, while the nodes form a block, therefore, the owners receive their share of the total reward. This principle is similar to mining pools, which now serve almost the entire Bitcoin network. Due to the initiation and stimulation of network members with smaller amounts, the level of its security is also increased. The EDC blockchain platform is one of the few pioneers which is switching its mining algorithm to the LPoS algorithm. All coin holders are merged into masternodes.
So, if I understand correctly, users can stake their coin to masternode candidates without launch a node. Right? But this is the same method which are using in DPOS system. And this is using a long time ago (the first blockchain was EOS as I know, who used this system).
As I know in DPoS mining token are given for some activity, for example for voting or participating in comunity life. In LPoS mining token are given for leasing. It is not necessary to do something. Just lease tokens.
