Technology has always been a driving force behind the evolution of the internet, and the emergence of web 3.0 is no exception. One of the key technologies that is poised to play a significant role in this next stage of the internet is Hashgraph
So, what is Hashgraph and how does it differ from the more well-known technology of blockchain?
First, it's important to understand that both Hashgraph and blockchain are distributed LEDGER technologies (DLTs). This means that they are systems that allow multiple parties to record and verify transactions in a decentralized manner, without the need for a central authority.
However, there are some key differences between the two technologies. One of the main differences is the way in which they reach consensus on the state of the ledger.
In a blockchain, consensus is reached through a process called "mining," in which participants compete to solve complex mathematical problems in order to add new blocks to the chain. This process can be resource-intensive and slow, especially as the size of the blockchain grows.
On the other hand, Hashgraph uses a different mechanism called "gossip about gossip" to reach consensus. In this process, each participant in the network shares information about the transactions they have seen with a few other randomly selected participants. This information is then passed along to other participants, until the entire network is aware of all the transactions.
This process allows Hashgraph to reach consensus much faster than a blockchain, as it doesn't require the intense computational work of mining. It also allows for higher levels of scalability, as the network can handle a larger number of transactions per second.
Another key difference between the two technologies is their approach to security. In a blockchain, the security of the ledger is dependent on the work required to solve the mathematical problems in the mining process. This means that, in theory, a malicious actor with enough computing power could potentially compromise the security of the blockchain.
On the other hand, Hashgraph uses a different approach called "virtual voting" to achieve security. In this process, each participant in the network votes on the order in which transactions occurred, and the majority vote determines the final order of the transactions. This makes it much harder for a single actor to compromise the security of the network.
Overall, Hashgraph has the potential to be a powerful technology in the web 3.0 era. Its fast consensus mechanism and strong security make it well-suited for a wide range of applications, including supply chain management, financial transactions, and even voting systems. While it may not completely replace blockchain, it is certainly a technology to watch as the web continues to evolve.
There are a number of cryptocurrencies that are built on top of the Hashgraph technology. One example is Hedera Hashgraph, a decentralized public network that uses the Hashgraph consensus algorithm to power a range of decentralized applications (dApps).
Hedera is unique in that it is governed by a council of reputable organizations, rather than being run by a single entity. This adds an additional layer of trust and accountability to the network.
Another cryptocurrency that utilizes the Hashgraph technology is , which is used to power the distributed ledger for their own proprietary cryptocurrency called "Hashcoin." Swirlds claims that their Hashgraph-based distributed ledger is faster, more secure, and more efficient than traditional blockchain technologies.
It's worth noting that these are just a couple of examples of cryptocurrencies that use the Hashgraph technology, and there are likely to be others as well. As with any new technology, it's important to do your own research and due diligence before investing in any cryptocurrency.
