A couple of days ago, we published an article on Planetwatch. In it, I toyed with the idea of a crypto mining super box that could mine different cryptocurrencies. Well, a few hours after it went live, I received an email from a reader informing me that there was indeed such a device.

It is called the Match X M2 Pro and costs a whopping $2,900. Initially, I was skeptical. The email was from a total stranger on the internet who was, for all intents and purposes, shilling a token in which he had invested. However, after I dug a little deeper, I found something to be explored.

Proof of Participation

The description of the miner states that it uses a “Proof of Participation” model for mining;

Proof of Participation (POP) model, M2 Pro offers a new type of mining in which the amount of tokens mined is determined by the value of the miner’s participation in the network itself.

With POP mining, as opposed to the more common POS or POW, a miner proves his participation in the network by mining “data blocks,” which use next to no power. In fact, the power consumption for the M2 Pro is minuscule, 4-6W. It looks very similar to a home WiFi router because internally, it is very similar and has similarities to Helium miners. The difference is that MXC claims to be compatible with large machines, not just small IoT devices. Oh, and you can mine Bitcoin with it too!

Proof of Participation is the principle behind the MXC token created by The MXC Foundation, a Berlin-based non-profit organization. MXC is an open-source Machine Xchange Protocol that connects Low Power Wide Area Network (LPWAN) technology with the blockchain.

What to mine

So how on earth does a 4W device mine Bitcoin in any real sense? Consumers own the gateway devices that receive rewards based on the POW protocol. Above them are supernodes run by staking partners who also receive MXC rewards. The infographic below details how the protocol works.

Sensor owners connect to the gateway owners via LPWAN. These then connect to supernodes which are created through token staking. The supernodes are, in turn, connected to full nodes, which are operated by parachains and link directly to the data buyers.

The MXC protocol reviews each node based on its participation in the network and removes any that are no longer active. Miners are then rated based on their participation. Rewards are then distributed based on this rating. The system promotes decentralization and for more users to join the network, making the network more secure.

Multi-token mining

The M2 Pro can mine DHX and MXC tokens by design. It can identify itself on the network to mine both tokens. However, this is the juicy bit. The MXC Foundation is about to announce the results of their pilot program to mine Bitcoin using an LPWAN device such as the M2 PRO. The project was called the Das Kaiser Projekt III and was available to the entire M2 Pro network towards the end of last year. To be a part of the project, you need an M2 Pro miner, miner health of 90%+, and 6,000 MXC tokens locked into staking.

How does it mine Bitcoin without hashing? It doesn’t. The device uses the POP protocol to measure participation in the network just as it does with its native token. Miners can then ‘mine’ Bitcoin through their devices and receive their BTC rewards in their wallets. Whether we should call this mining is now up for debate. Squirreled away on their website, they explain the process in more detail. When ‘mining‘ Bitcoin, the network

leverages the collective network strength and reliability into a cloud mining unit that acts as a unified bidder to request for a swap for BTC in a predictive AMM market.

So they are not mining Bitcoin, then?

DKP II utilizes a powerful scraping tool to scan transactions and liquidity orderbook to set a forward-oriented valuation of BTC to ensure maximum bidded swap between POP mining rewards and BTC’s POW mining rewards.

The short answer is, unsurprisingly, no. A 4W device is not capable of hashing at th...
