NEM also has a dedicated team working for them. And decentralization is not based on whether the developers belong to a company. I dont posess the knowledge about RaiBlocks to exactly know where the differences reside in.

The Dogecoin ledger uses the proof-of-work consensus mechanism to validate the transactions on its blockchain. However, a notable difference from bitcoin is that it uses the scrypt hashing function. This hashing function is significant in that it is designed to make it difficult for the development of ASICs miners.

 At all corners of the Internet, you’re going to hear people say to invest in multiple coins, and to avoid over committing yourself to one brand of cryptocurrency. While this advice holds true for practically every other form of investment, it’s not the case here with crypto.

As its popularity mushrooms, so does the transaction processing requirements to facilitate the network. Because of the “proof of work” (or POW) requirements necessary for a decentralized bitcoin network to confirm transactions, it takes brute-force computer effort by many computers (called “miners” in bitcoin-speak) to make that happen.

 The team's goal is to provide a stable open platform for payment systems, banks, and crowdfunding projects, and to create an ecosystem for community-based projects.

Still, the market downtown as a result of Big Bitcoin’s tanking illustrate how the majority of cryptocurrencies still rely on Bitcoin for liquidity and valuations. There is a possibility that in the coming years, Stablecoins will become the new metric by which most altcoins are judged, fulfilling the prophecy of full-scale divorce of cryptos from the necessary Bitcoin pricing. If or when this happens, the actual value of tokens will be more clearly expressed.

I think technology serves a purpose. Most people don’t care how their smartphone or the internet works, as long as they can benefit from what it does for them.So I’ll skip the whole ‘what’s a blockchain’ part.
