Cardano, the coin who wants to solve the problems of cryptos! Cardano is the world's first **peer-reviewed blockchain**. This means that the Cardano team made sure that experts from all around the world, check their papers and approve them. This is why the cardano asset took more than 2 years to be created. The cardano **blockchain** is made up of 2 layers: ➖Cardano Settlement Layer, where the **transactions** of ADA occurs ➖The Control Layer, which will be used for the **smart contracts**. Cardano aims to solve the **problems** of cryptocurrencies: ◼️**Scalability**: ➖The system of PoW is known for being slow and inefficient, both for wasting computer power and electricity. Cardano, instead, adpots the PoS. The network elects a few nodes to mine the blocks. Cardano (actually its algorithm) divided time into **epochs**, and then epochs into **slots**. To each slot (which represents a fixed period of time) is assigned a **slot leader** which has the duty to **verify** the transactions and write them in the block in the specific time frame. If a slot leader fails to verify all the transactions in time, it is no more allowed to produce blocks and has to wait to be **elected** again from the network. This whole method (which is called **Ouroboros**) is much better than PoW because it allows to split epochs in more slots and lets run multiple epochs in parallel to face the increasing number of transactions. ➖With the old sistem of PoW, each node in the network receives a copy of the transacion that needs to be verified. Thousands of transactions per second * thousands of miners make the **PoW unsustainable** on the bandwidth side. Cardano instead **splits** the network into **subnetworks**, reducing the amount of bandwith needed. This splitting tecnique called **RINA**. It allows the different networks to **communicate with each** other if needed but letting them still to be split and **operating individually**. ➖The **storage** of the blockchain is also a problem of scalability. For now the problem isn't still tackled, but the cardano team will use methods of **Partitioning** , **Compression** and **Pruning** to reduce the "weight" of the blockchain. ◼️**Interoperability**: ➖The cardano team aims to make a blockchain that "**talks**" to other blockchains. This would result in moving assets **across** multiple chains. ➖Cardano wants even to be trusted by banks, allowing users to "name" their transactions, setting a **sender/receiver** name plus a **reason** for the movement of coins. This still remains a **choice of the users** whether to put this information or not. ◼️**Sustainability**: Many cryptocurrencies born recently launched a ICO (initial coin offer) to obtain a **capital** to develope the asset. Have you ever wondered what happens if those money isn't enough for the whole existence of the asset? Cardano team did and they came to a solution! Each transaction will pay a "**tribute**" to a treasury who will store a **capital** for the **developers**. The treasury itself is basically a **smart contract** which will hold the coins that will release part of the funds to **improve** the cardano **protocol**. Developers will submit a proposal of improvement to the community. The **community** will vote for the **best** of the **ideas** proposed and after some time the **treasury** will give enough money to **develope** the **improvement**.
