It's interesting that SpiderPool, one of the largest mining pools in the world, has just launched support for NAT distribution. Overall, this seems like a serious move — on April 17, they implemented NAT broadcasting directly into a Bitcoin block, which symbolically marked the transition to a two-tier reward system.

For those who are not in the know: NAT (DMT-NAT) is a cryptocurrency generated along with each Bitcoin block every ten minutes. Its feature is that it has the same computational power and structure as BTC itself — the same blockchain, blocks, addresses. Currently, about 386 million NAT are issued per block, which is roughly $38. The project's total market cap is now around $38 million.

What’s interesting about SpiderPool’s approach is that the block reward slowly decreases depending on difficulty and block height. All the code is open-source, adding transparency. When the reward reaches $50,000 (this will be at a market cap of $50 billion), it will seriously offset some of the miners’ costs and could completely change the dynamics of Bitcoin mining. SpiderPool seems to be betting that this could truly be a game-changer for the industry.
