Analysis: What is "double digging"? Not as simple as you think

Under the environment of high mining cost and many new projects flying together, double mining has become a trump card for many projects. In order for miners to achieve a higher profit for a mining machine, dual mining has also become a method that miners are scrambling to take. For many people, double mining or multiple mining can get more tokens, but is it really the end? It doesn't seem as simple as you think. Today, we will focus on the problem that everyone in the Lava community is currently paying attention to-double digging, and see what is going on.

What is double digging? In short, dual mining is a mechanism that allows different cryptocurrencies using the same algorithm to mine at the same time. In other words, miners can use one mining operation to achieve the effective block production of two or more tokens at the same time, and they can get an effective block reward. For miners, the biggest advantage of dual mining is that it can greatly reduce investment costs; for projects, tokens with lower computing power can be obtained through dual mining and anchoring with high computing power projects. High computing power.

In fact, dual mining is not a new product. BTC with PoW as the core mechanism and early Ethereum have miners on the market to maximize the value of the miner through dual mining, although this requires a large amount of graphics. So what is the dual mining for PoC projects? We all know that the biggest difference between PoW and PoC is that PoW uses CPU or GPU mining, while PoC is hard disk mining with more decentralization, low cost and energy saving. However, PoW and PoC adopt the same double-digging method. PoC requires the process of P disk before double-digging.

At present, most PoCs use the "PoC2" Plotting algorithm. This will cause the "answers" searched by miners to have similar generation logic and verification rules. This also makes many PoC projects uninformed. This makes double digging between projects possible. However, it is not necessary to successfully pack blocks to complete effective double mining. It must meet the two conditions: the consensus process and the asymmetric encryption system are the same.

Recently received community feedback, other PoC currencies can achieve dual mining Lava through its Plot ID. The Lava team is very concerned about this issue. Frankly speaking, Lava did not deliberately consider double mining with other PoC currencies at the beginning of the design, and never considered relying on double mining to quickly improve his computing power. Lava's existing computing power is slowly accumulated from scratch, and has never actively sought other currencies to double-dig. For users of dual mining, because the Lava public key system is not connected to other PoC projects, even if the miner digs into Lava through dual mining, it cannot really achieve a profit in Lava's network, that is, mining is invalid.

Lava has implemented open source on GitHub, and all the code has been open and transparent. For the possibility of double-mining the probability of Plot ID common to other currencies and Lava, Lava cannot guarantee it completely. If the user wishes to obtain and use this kind of Plot ID, we only remind the risk and require the user to identify and bear the responsibility. For Lava, dual mining is only a temporary technical reality, not a technical loophole.

It can be said that Lava is based on the proven technical practices in the blockchain field and its own development needs to form the existing core frameworks of existing cryptographic algorithms, public and private key address systems, UTXO models, and flint mechanisms. Lava has never included dual mining in its core research scope. Of course, the Lava team is actively following up on the PoC3 algorithm and is actively verifying the feasibility of upgrading PoC3 or using a hybrid algorithm.

As PoW's energy waste, high cost, and concentration of computing power become more serious, the opposite of PoC is gradually known in the industry. The air is coming, and more and more projects are pouring into the PoC field. Lava, as a leader in the field of PoC, hopes to lead the PoC ecosystem, thereby promoting the further development of the blockchain industry, and thereby making "everyone can mine" a reality, so that the blockchain can truly land, not by people. The price of playthings in the high cabinet.

Lava is based on condensing the global "root of trust" and building a "top-level index" as its vision. By consolidating global storage consensus, it is guided by the use of maximum space resources to prevent meaningless storage resource waste. Through the cross-chain solution, Layer 2 is embedded in an unlimited number of regions and an unlimited number of content-based addressable distributed storage networks, and a de-trusted basic environment is provided through the "spatial computing power" of the main chain to achieve distributed network resources Top-level indexing, resource scheduling, and matching and recording of transaction behavior.
