When analyzing a project, the Eden Labs team looks for projects that do something unique or do it much better than its competition. Quality projects should be able to explain complex ideas simplified to their audience. In addition, projects that rely heavily on a broad user base have to have an incentive for the first ten people to join the network before a million users is ever achievable. No project will succeed if it requires a million participants to bring any value to its users.
Hedera Hashgraph utilizes a new form of distributed ledger technology, the Hashgraph. This tech enables networks of nodes to communicate with each other and reach consensus in a decentralized manner. The Hedera Hashgraph platform is fast, secure, and only requires a small amount of computation power to maintain the network. Low computation requirements allow anyone to run a node and develop apps on the platform.

The Hedera Hashgraph platform attempts to solve the issues plaguing the mainstream adoption of decentralized ledger technologies. While standard blockchain solutions struggle with performance, security, governance, and stability, Hadera Hashgraph addresses and improves upon all these areas.
Standard blockchain solutions currently lack scalability, stable governance, and satisfactory performance. It is well known that the current state of decentralized ledger technologies lacks the crucial aspects needed to sustain the ever-increasing scalability and finality needs facing the industry. Hashgraph presents a new method for maintaining a decentralized ledger.
A Hashgraph is fundamentally different from a blockchain. While a blockchain is a chronological and continuous chain of blocks, a Hashgraph is much like a tree with its branches woven back into its main body. The Hashgraph is a new approach that significantly differs from other interpretations of distributed consensus and looks to provide an upgrade to the current state of DLT. Essentially, Hashgraph is a data structure and consensus algorithm that is faster, fairer, and more secure than the blockchain.
Hedera Hashgraph is a semi-permissioned network that uses two special techniques to outperform standard blockchain technology. The two methods are their unique Gossip Protocol and Virtual Voting. The Hashgraph consensus does not require any votes to be sent since every member has a copy of the hashgraph. If Alice and Bob both have the same hashgraph, then they can calculate a complete ordering of the events, and they will both get the same answer. Thus, consensus is achieved, even without sending vote messages.
The downside to this process is that the network is semi-permissioned. While anyone can run a node, the system is governed by a council made up of 39 organizations. These 39 organizations have not yet been announced. Additionally, because of the asynchronous nature of the network, each consensus round must have a defined set of nodes. Essentially, each round is permissioned. This is in contrast to more decentralized networks where nodes can come and go as they please and freely participate in consensus.
Hedera Hashgraph is asynchronous and thus, does not make assumptions about the timing of transactions. Its asynchronous structure means that events in the network are not coordinated into an ordered timeline of transactions and processes can run independently of one another. In order to ensure that all information is propagated to all nodes in the network, the Hashgraph gossip protocol is implemented. The Gossip Protocol spreads information among a network of nodes quickly and effectively. It allows a node to randomly select and transmit all known info to another node in the system. This process is repeated across the network until everyone is aware of the given information. While blockchains generally make use of gossip protocols to propagate messages throughout the network, Hadera uses a different method. Instead of ‘gossiping’ about one transaction at a time, the gossip protocol allows for “gossip about gossip.” This means that when one node passes a message, other receiving nodes in the network continue to propagate that message, ensuring that eventually, the entire network receives the message. This ensures, because of the asynchronous nature of the network, that nodes maintain a similar state. Members who have slightly different versions of new events will quickly converge to the accepted state by continuously gossiping with one another. This protocol optimizes the communication process and ensures consistency on the network.
Not only does each node of the Hadera network see the same information, but the gossiping protocol ensures that each node also knows how all other nodes came to learn about the information. This permits Virtual Voting to occur, since nodes can calculate what other nodes would have sent them if they voted, without having to actually vote. Nodes on the network know how and what other nodes know, and what they know. Virtual Voting is used to verify whether a message was valid or forged by some malicious member of the network; thus, all nodes have to vote on the matter. Since each member of the network shares their copy of the Hashgraph, and everyone knows exactly what everyone else knows, Virtual Voting can take place. This means that each node can virtually calculate how other nodes would vote and construct the consensus without ever sending or receiving a message. Virtual Voting is advantageous since it requires very little bandwidth and ensures that members always calculate their votes according to the defined rules. It also does not require a message to be sent between nodes, and thus, it is not vulnerable to a denial of service attack or overhead bottlenecks.
The Hashgraph is fundamentally different from typical blockchain architecture. Hedera Hashgraph has implemented protocols which have enabled it to outperform traditional decentralized ledger solutions. Hadera has already demonstrated speeds of 100,000 tps. Through the use of the gossip protocol and virtual voting, Hedera Hashgraph can retain the chronological ordering of transactions while maintaining scalability and using minimal broadband capacity. However, the downside is that Hadera has a permissioned element and thus, lacks the privacy and decentralization of other platforms.
The Hedera Hashgraph roadmap is simple; there are no dates provided at all but only phases of operation. With Phase I complete, we are currently in Phase II. From the provided information for the roadmap, we can see that the Hashgraph is still under construction. There are still some critical developments needed before Hashgraph can be considered complete; this will take some time.
Token Acronym: N/A
Circulating Supply: TBD
Total Supply: 50 Billion Hedera Tokens
Intrinsic Value of the token:
The Hedera Hashgraph network will have a native cryptocurrency, which is a utility token that grants token holders access to distributed applications on the platform. The token may also be “staked” and used to run a node, thereby providing network security to the public ledger.
Token holders will pay transaction fees to access distributed applications on the Hedera Hashgraph platform. These transaction fees are paid to Hedera and to the network nodes that contribute to the consensus process.
Hedera Hashgraph is missing some vital information regarding the token economics of the network. Currently, no information has been provided about the token. The token will have an intrinsic value as a utility token in the system; however, in order to have a more precise picture, more information is needed.

Hedera Hashgraph has a sizeable social media following and is maintaining frequent activity across its social networks. All major social media platforms are being utilized and frequented by the team members.
Hedera Hashgraph is offering a unique platform through their implementation of key elements such as virtual voting and their unique gossip protocol. These novel systems enable a fast, fair, and secure network. The team behind the project is well suited and experienced for the task. The technology behind Hedera Hashgraph is potentially game-changing and has significant potential, but improved technology may not immediately guarantee adoption. As other forms of DLT continue to improve, much rests on the Hadera’s team’s ability to develop a viable product. In addition, there are centralization concerns around HashGraph. Hadera uses patented technology and will never support a free, open-source platform for dApp development. Thus, Hadera will likely only be optimal for specific use cases. Hadera sacrifices decentralization in favor of security and scalability.
