What is Coin Magi?
Magi (XMG) is a PoW/PoS hybrid coin (mPoW/mPoS). Magi is designed with difficulty dependent mining reward for proof-of-mining (PoW) blocks in order to put network hashrate under a certain limit. Magi at the first time implements a novel proof-of-staking mechanism, to frustrate potential attack through accumulating a large number of coins and offline staking time. Magi is at the first concentrating on the low cost in maintaining its block system, for example, through cost effective mining devices. To this end, Magi, aiming at fairness, cost effective and energy efficiency, strives for every single effort to make mining be available to everyone, and provides an even playing field for people looking to issue digital coins without expensive equipment.
mPoW, the magi’s proof-of-work (PoW) protocol, in addition to required computational works to be done to deter denial of service attacks, is also a network-dependent rewarding model system. The mPoW rewards participants who solve complicated cryptographical questions not only to validate transactions but also to create new blocks and generate coins. The amout of coins generated are constantly monitored by the mPoW protocol and tuned on the basis of an attraction-repulsion model: 1) incremental rewarding to stimulate network activities during passive mining phase, and 2) decremental rewarding to mitigate redundant mining sources during agressive mining phase. mPoW can effectively govern the magi’s network and limit it under a certain scale, enabling the general devices to be capable of mining magi. ++ For details - A network-dependent rewarding system: proof-of-mining
mPoS, the magi’s proof-of-stake (PoS) protocol, aims to achieve distributed consensus through operations in addition to mPoW. mPoS is designed such that it rejects potential attacks through accumulating a large amount of coins or offline staking time, either of which leads to security concerns. Similar to mPoW‘s operation, mPoS is constructed in accordance with the concept of the attraction-repulsion model. Magi hybridizes mPoW with mPoS, and integrate both consensus approaches in order to acquire benefits from the two mechanisms and create a more robust payment system.
