What problem does this service solve?

Gulden allows users to make P2P payments. It has gained some adoption in the Netherlands, but it does not appear to have any significant advantages to other coins.

Sphere's goal is to create a digital currency with a fair distribution model.

ZClassic is a fork of ZCash. The key differences are that ZClassic doesn't charge miners a fee and there are no limitations to create artificial scarcity in the coin supply.

Company Description

Gulden is a Dutch cryptocurrency based on a native blockchain with a Proof-of-Work (PoW) consensus mechanism. Gulden has gained traction in the Netherlands, where it can be used to make P2P payments, as well as send funds to an IBAN account. Gulden's marketing efforts emphasize the network's security and faster transaction times. Gulden's PoW² consensus combines aspects of PoS with PoW, and allows witnesses to add transactions to blocks after they have been mined. The network is powered by the NLG coin.

Sphere is a smart contract platform and peer-to-peer payment network. The network has a hybrid PoW and PoS consensus mechanism and is powered by the native SPHR token, which can be swapped for an ERC20 token over the Ubiq smart contract platform.

ZClassic is a privacy focused crytpocurrency that is a fork of ZCash. ZClassic enables a high degree of privacy and anonymity of transactions.The key differences between ZClassic and ZCash are the elimination of the 20% mining fee that are allocated as a "founders' reward" and the removal of ZCash's block limit, that was intended to create scarcity.
