Can MASS POC+ cloud computing power bring new liquidity and investment effects to the mining industry?

Preface

As we mentioned in the previous questionnaire, the two largest currencies in the mining industry, Bitcoin and Ethereum, are about to face opportunities and challenges. On the one hand, after the Bitcoin halving in early May, the old Bitcoin mining machines are facing a shutdown trend. The S19 series has become the main model, but the static payback period is not short. On the other hand, the 4G graphics cards for Ethereum mining will be gradually phased out this year, but will they also gradually transition to POS in the next two to three years?

From the perspective of community consensus, POW>POS>various innovative consensuses (POC, POA, POD, etc.). From the perspective of mining, POW is undoubtedly the only No.1, but now POW represented by BTC and ETH is facing halving, elimination of 4G graphics cards, and switching to POS. Small miners and small mines are facing the crisis of elimination. Innovative mining seems to have smelled an opportunity to catch up.

We actually learned about the PoC consensus mechanism from Filecoin. The PoC capacity proof mechanism is simply the process of using the idle space in the computer hard disk for storage to obtain income. As a deep participant in the mining ecosystem, Aladdin PoW Labs has been tracking and observing various consensus mechanism projects such as PoS equity proof mechanism, PoC capacity proof mechanism, DPoS, PoD, etc. while mainly researching PoW projects. Mass is also a PoC project that is really worth introducing among the recently collected research projects.

I just briefly introduced the PoC capacity proof mechanism. The mining process is as follows:

Step 1 In the initialization phase, the miner node generates a series of data according to the protocol and stores it in the capacity space.

Step 2: The miner generates a random number based on the current block parameters, retrieves a part of the data in the capacity space to generate a proof, which is the so-called capacity proof, and submits it to the network along with the block to participate in the competition for the next block.

Step 3 The submitted capacity proof and block data can be verified by any node in the network. The best capacity proof of the entire network is selected according to the quality formula. If the block data and proof are valid, the miner who provides the best capacity proof for this round of block production will obtain the right to produce blocks and the block production reward.

It is the first blockchain developed using the MASS capacity proof consensus protocol. The main network produces a block every 45 seconds, and each block rewards 1024 MASS. It has been running smoothly since its official launch in September 2019. The total amount of MASS on MASS net is 206,438,400. The project has no fundraising and no pre-mining. MASS net provides users and developers with full-node wallet clients, mining node clients and other tools.

MASS Engine

As the underlying support for the project, MASS Engine has the following features:

Security: The MASS capacity proof protocol, which adopts the idea of ​​time-space replacement, ensures the unforgeability of capacity proof; the use of capacity as proof and verifiable random functions ensures that the MASS system has 51% fault tolerance; the fork detection penalty mechanism can resist the fork chain annihilation of the main chain caused by the Nothing-at-Stake attack.

Fairness: The MASS capacity proof consensus protocol ensures that the probability of a node producing a block is only related to the effective capacity proof provided by the node, and the proof of effective capacity size has nothing to do with the storage medium of the data, so that all nodes participating in the maintenance of the MASS network have similar marginal costs.

Low resource consumption: In the MASS capacity proof protocol, computing resources are consumed only when initializing the capacity space. When entering the block consensus stage, the data access to the capacity space is O(1). Therefore, the use of the MASS capacity proof protocol for block consensus does not require continuous power input. When the MASS system performs block consensus, the computer resource consumption accounts for a very low proportion and does not affect the normal use of the computer. When the computer does not participate in the consistency maintenance of the ledger data in the MASS network, it can directly format the capacity space for other uses.

Universal and highly scalable: During the block consensus process, nodes only need to query the initialization space and do not perform data operations on the initialization space. Therefore, the same capacity space can provide capacity proof for multiple block consensus instances. Nodes using the MASS capacity proof protocol can support multiple blockchain instances in parallel.

Layer2

At present, Layer2 is still under development. According to the description of the project masters, I conclude that the functions of this Layer 2 are relatively consistent with those of Layer 2 of most public chains. However, as Laryer 2 under the PoC mechanism, MASS is likely to become the first alliance chain in this mechanism, and continue to empower the development of more PoC projects in the future. The research and development and final implementation of Layer 2 will advance the PoC ecosystem from the BTC (PoC1.0 era) to the ETH (PoC 2.0 era).

Cross-chain

Finally, we also see in the Road Map that MASS will also develop cross-chain functions, that is, it will become the first PoC consensus project that integrates public chain + alliance chain + cross-chain. The direction is quite standard, and we look forward to witnessing the integration of the three chains in the future.
