Every day coin EDC blockchain is a blockchain technology that uses the more advanced form of proof-of- Stake consensus in the form of Leased Proof-of-Stake (LPos). Every blockchain project requires a consensus mechanism to help validate a transaction block and check against double spending i.e sending the same money to different people on different chain. 
LPoS is an enhanced version of Proof-of-Stake. In a regular Proof-of-Stake system, each node that holds a certain amount of cryptocurrency is eligible to add the next block to the blockchain.

Proof-of-Work (PoW)
Proof-of-Work is a consensus algorithm which requires a block generator to perform an expensive computer calculation, also called mining, that needs to be performed in order to create a new group of trustless transactions (the so-called block) on a distributed ledger called blockchain.
Mining serves have two purposes:
To generate a chain of blocks which can be considered as the only one main chain (since it's too resource-consuming to create alternative one)
To create new coins (increasing total supply) by rewarding miners for performing the previous task.
When you want to set a transaction this is what happens behind the scenes:
Transactions are bundled together into a block.
Miners verify that transactions within each block are valid.
Then miners should solve a mathematical puzzle to generate a valid block.
Block with solved puzzle considered as valid and broadcast to all nodes in the network and stored in the public blockchain
A reward is given to the first miner who solves each blocks problem.
This “mathematical puzzle” has a key feature: asymmetry. The work, in fact, must be moderately hard on the requester side but easy to check for the network. This idea is also known as a CPU cost function, client puzzle, computational puzzle or CPU pricing function. All the network miners compete to be the first to find a solution for the mathematical problem that concerns the candidate block, a problem that cannot be solved in other ways than through brute force so that essentially requires a huge number of attempts. When a miner finally finds the right solution, he/she announces it to the whole network at the same time, receiving a cryptocurrency prize (the reward) provided by the protocol.
'51% attack' refers to an attack on a blockchain system. By controlling the majority of the computing power on the network, an attacker can release his new fork and regains his coins by executing a "double spend" attack which will allow his own coins to be spent multiple times. The attacker could spend coins in one place, allow the coins to enter the blockchain as normal until the required confirmations are met, then fire up their 51% of the miners to craft a fraudulent fork of the blockchain in which those coins were never spent, allowing them to re-spend the coins. This could theoretically be repeated for as long as the attacker maintained control of 51%.
The advantage of a Proof-of-Work network is that the majority of voting power when implementing important changes to the system is divided among miners, developers and other crucial members of the community. Meanwhile, in a Proof-of-Stake network, major stakeholders have a technical ability to make any changes they like without considering the will of the community, businesses, miners, and developers.
This centralization of voting power and, essentially, control of the network defeats the purpose of a distributed ledger-based cryptocurrency since it contradicts its entire principle of distributing all elements within the network to avoid the presence of a central authority.
#Proof-of-Work Disadvantages
Requires more electric power which in turn costs the miner.
High computing power hardware which is expensive.
Possibility of miners moving their hardware to mine a different coin if the reward is better there (loyalty).
With more and more coins (like more count of bitcoins) getting released, miner’s reward would come down as the coin becomes scarce to mine.
Proof-of-Stake (PoS)
Proof-of-Stake is a different way to validate transactions based and achieve the distributed consensus. The purpose is the same of the proof of work, but the process to reach the goal is quite different.
In PoW number of miner's blocks is proportional to the amount of hardware resources and energy he invested. In contrast, in PoSa person can mine or validate block transactions according to the amount of coins he or she holds. So unlike the Proof-of-Work, the creator of a new block is selected in a practically random manner, with greater amounts of stake increasing the likelihood of adding a block to the chain.
Usually, in the PoS system, there is no block reward, so, the miners take the transaction fees. That's why miners are often called block forgers or generators, instead.
With a PoS, the attacker would need to obtain 51% of the cryptocurrency to carry out a 51% attack. The proof of stake avoids this ‘tragedy’ by making it disadvantageous for a miner with a 51% stake in a cryptocurrency to attack the network. Although it would be difficult and expensive to accumulate 51% of a reputable digital coin, a miner with 51% stake in the coin would not have it in his best interest to attack a network which he holds a majority share. If the value of the cryptocurrency falls, this means that the value of his holdings would also fall, and so the majority stake owner would be more incentivized to maintain a secure network.
Advantages of Proof-of-Stake
Significant advantages of Poof-of-Stake include
energy efficiency
The Proof-of-Stake method is for a more greener and cheaper distributed form of consensus.
In Proof-of-Stake, forgers are always those who own the coins minted.
Leased Proof-of-Stake (LPos)
EDC blockchain uses this type of consensus mechanics.
LPoS is an enhanced version of Proof-of-Stake. In a regular Proof-of-Stake system, each node that holds a certain amount of cryptocurrency is eligible to add the next block to the blockchain but in the LPoS system, on the EDC Platform, users can lease their balance to full nodes. With LPoS, the user will have the ability to Lease EDC from the wallet to different contractors which can pay a percentage as a reward. The larger the amount that is leased to a full node, the higher the chances of that full node being selected to produce the next block. If that full node is selected to produce the next block, the leaser will then receive a percentage of the transaction fee that is collected by the full node.
In a Leased Proof-of-Stake environment, users can choose between running a full node or leasing their stake to a full node with receiving rewards. This system allows anyone to participate in the EDC network maintenance.
User can lease his EDC through leasing on any computer or mobile device that has an internet browser since provides a lite client solution that does not require "Miners", that are leasing their balance to store the whole Blockchain or to have the wallet running.
