OpenLedger is based on the BitShares’s “market peg” idea. BitShares differs from WAVES in two fundamental ways. First, its consensus algorithm is DPoS, meaning that only a given number of “delegates” have the power to validate blockchain transactions, as opposed to the PoS consensus where each full node is accredited for validation. This means that the WAVES platform supports full decentralization whereas BitShares team is not taking a step out of their “delegated” version. The second difference is the feasibility of the “market peg” approach. This is of course open to discussion, but one may objectively evaluate the success of that approach by looking at the history of their most praised market pegged crypto-asset, namely, BitUSD. I doubt if any big corporation in the future will ever decide to rely on the idea “if everyone thinks something is worth 1 USD, then that thing is forced to be worth 1 USD.”
