This is a key point on my todo research list. Federated servers don't work? Or wouldn't be trusted by the market?
Federated servers are just a hack to be able to test prior to getting the necessary softfork. Without the proper two-way peg where coins are secured by an SPV proof against the Bitcoin blockchain, this is fundamentally no different than any other off-chain solution where coins are being held in some form of custody.
This needs to be proved, It doesn't appear to be true, any business relationship is based on trust. The federated service will be (should become) as trusted as the service or product you purchase 100% dependent on reputation.
e.g. if i buy a particular security (product / service) I trust (1) it is what it is, this is
reputation and then I must trust the person proposing the business opportunity, trust (2), this is
reputation.
If trust (2) can be violated, guaranteeing trust (1) is irrelevant because it was misrepresented by an abuse of
reputation. arguing that we need SideChains to increase trust (1) is not a valid reason to reduce trust, we still are reliant on
reputation.
Gmax and Lukejr and other SC proponents see trust (1) as a holy grail, news flash, the mortgage backed securities if constructed in a trust free "blockchain technology" environment would still be dependent on the
reputation of subjective evaluations and selling false promises.
solving the
reputation dilemma is more valuable to society, this technology without Federated servers is not innovation in trustlessness, just because it is done in a trust free way using SPV proofs doesn't solve the problem of trust as reputation, if anything it allows reputation to go unscathed as the SPV proof executed a multistig contract that was agreed, it executed flawlessly as both parties agreed, too bad you trusted some subjective AAA reputation system.
