Hive mining: Litecoin developers Cash offered his protection from attack 51%

For anybody not a secret that in recent years, cases of attack of 51% when the network algorithm attacks the PoW of the attacker having power to maintain more than half Hasrat. Having 51% Hasrat, an attacker can overwrite and cancel transaction to carry out double-spending of funds through the exchange and another . Attacks from 51% at the time hurt Bitcoin, not so long ago — Bitcoin Gold Verge, Litecoin, Cash, and possibly other network. Under threat of Bitcoin and Ethereum Cash Classic. Mining giant Bitmain is coming to own 51% of the network power of Bitcoin. Fear and horror.

How to protect your network from attack 51%?

Many coins are working on the encryption algorithms other coins. SHA-256 use Bitcoin, Bitcoin Cash, Cash Litecoin, Peercoin, Zetacoin and others. Ethash ensures the security of Ethereum, Ethereum Classic, Pirl, Ellaism, Expanse and many others. As soon as "Junior" cryptocurrency decides to use an encryption algorithm that is already in use "older" crypt, she puts herself in danger of attack 51%.

In the case of Litecoin Cash, the risk is compounded by the fact that you use the SHA-256 algorithm, which runs the Bitcoin network is the most secure and sophisticated network in the world. Even the tiny fraction of power is not very large mining-pool is enough to compromise a weaker network.

Obviously, require additional verification of transactions on the network. With this purpose, Ethereum, for example, introduces the Casper Protocol, which (PoS) and reduce the reward received by the miners.

What's wrong with Proof-of-Work?

In the classical blockchain security based on the algorithm PoW miners are competing, hoping a huge number of potential block hash to find the one that corresponds to the given target complexity and meet the parameters of the consensus network.

What happens if the difficulty of mining will suddenly drop to zero and any hash will be accepted by the network as valid? Because "work" in a proof-of-work will no longer be any node in the network can easily mine blocks.

At First, such a scheme may seem attractive; mining will no longer require energy expenditure. But in practice, any cheap will mine these blocks and push through them to the network simultaneously, which will lead to the emergence of many candidates among blocks to prolong the chain. Because the miners will not know which block to choose for the continuation of the blockchain, a lot of abandoned chains (orphan).

Although such a network could achieve some kind of consensus, it probably will include numerous reorganizations of the chain and cancelled transactions. This situation is familiar to anyone who watched the launch of the pure PoW coins with an inadequate algorithm adjusting the difficulty.

With zero complexity, when for the production of block don't need anything else the network will not only be able to tell which candidate chain is better and a priority, but the miners will be able to work on different chains with impunity.

This thought experiment shows that the main purpose of proof-of-work, proof-of-stake or proof-of-anything — to give the network a sure mechanism to determine who has the right to mine or otherwise to extract the next unit, so agreed with him the rest of the participants. In addition, the miner should not have the possibility to create different combinations, without risking anything.

What is a hive-mining?

Hive-mining (hive, hive = a hive) is an alternative form of competition for the unit, where the production unit is provided by the agent working on behalf of the user. These agents, the "worker bees" are in the blockchain. They are fully decentralized and are created when the user performs a particular transaction.

After creating the worker bees work as a mining-farms, and their owners become "keepers". When a worker bee successfully finds a block, the reward per unit (including Commission) paid to the beekeeper. Bees do not require any energy, so for the production units will not require any specialized equipment.

The worker bees live for a limited time, and the creation of bees is expensive. The success of a given bee depends on the population of bees in the network, although some bees may never find a block, while others would be disproportionately successful. In this sense it is more like solo mining.

hive-mining or proof-of-work/proof-of-stake?

Hive-mining requires very little energy expenditure. In the scheme in which proof-of-work is replaced by hive-mining, the total energy cost is approximately two times smaller if compared with pure PoW, if the difficulty will equally share the production of blocks for each algorithm type. So say the developers.

Hive-mining does not require investment in hardware and additional work on the circuit would mean that for the attack 51% on the network, the attacker will need to own 51% Hasrat network and 51% of the bee population. It will be immediately obvious.

The Need to invest in bees means that the internal inequality proof-of-stake, when the rich getting richer will be eliminated. In proof-of-stake reward per block is mostly a passive process for the Staker, which requires that only his wallet was online. To provide in such a system, the distribution in which the bulk of the currency will not accumulate a large stake holders, and small business owners cryptocurrency impossible.

Well, let's see how LCC will be able to implement your protection method. The developers promise to introduce the function to create the bees in the next few weeks.
