Here is another candidate for the title of high-speed blockchain. The developers promise to increase the current transaction processing speed and reach millions of transactions per second. If it succeeds, it will be hard to compete with Harmony.
An American company called Harmony is working on the project. Among the features of the project, the team highlights:
- High blockchain speed. In theory, they promise a throughput of up to 10 million transactions per second;
- Energy efficiency and speed of operation. Blockchain platforms use PoW in their work. Harmony has settled on PoS. More important is the number of tokens stored in the wallet;
- A dynamic PoS entry threshold. Depending on the load on the network will change the entry threshold for mining wallets. It is promised to be quite low, and many small players will mine crypto this way;
- scalable network infrastructure. The developers promise a fast exchange of data between shards.
Harmony ONE team is not the only one working in this direction. Among competitors, we should mention Zilliqa, High-Performance Blockchain, and Dfinity. Today you can easily exchange avax to one. 
How the FBFT consensus algorithm works
In general, let’s understand how transactions are confirmed:
- The leader creates a new block. Its header is passed to the validator nodes. At the same time, the validators receive the content of the block using “erasure coding”, the principle of this technique is shown in the figure below. This is called the declaration phase;
- the task of the validators is to check the correctness of the block header, sign it with the BLS signature and send it back to the leader;
- the leader waits until there are 2f+1 responses from the validators. Their answers are then combined into a BLS multisignature and broadcast to the network. This takes into account the “weight” of the node; the more ONE tokens stored in the wallet, the more weight the validator has. The leader also takes his voice into account when counting answers. This concludes the preparation phase;
- the validator nodes come into play again. They now check to see if there is a 2f+1 validation of the block header. They also check the contents of the block (which they got back in the first phase).
The cryptocurrency ensures the existence of the project. The options for its use are:
- As fuel for transactions, the closest analogy is gas in ether;
- Admission to mining by the wallet. The developers promise a low entry threshold for mining, but a certain amount of money in the wallet will have to keep. Miners will provide the demand for ONE token;
- an object for investment and speculation. Like other cryptocurrencies, this token has good volatility and daily volumes. Investors are putting a lot of money into this token..
- As for the rate, crypto has been moving in the $0.020-$0.028 price range since the beginning of June.
