I studied Holochain and Hashgraph and would like to talk about these two projects. The following is my own opinion. Again, just my personal opinion. Please share your opinion on these two projects and other projects of next generation of [Suspicious link removed]paring with Holochain, Hashgraph has already lost, totally.
Encrypted psycho-relativism:
HashGraph represents the capitalism and elitism of Silicon Valley. HashGraph Has Presale. Presale is only for a limited number of accredited investor. The majority of investors are not qualified, and they are helpless.
While, Holochain represents freedom, openness, coompatibility, and the spirit of crypto-liberalism. It is Nakamoto's crypto-romantic thought. No presale, No VC, No Instituion. No Bias, No Discrimination. As long as you have discovered the project with your eyes, you can participate without limit. Everyone can join the project.
Market Value Theory
The presale of HashGraph equals holochain's entire financing. Is that a Joke? A project that is born at the 15th place at coinmarketcap and is only at the theoretical stage with a white paper.
The Holochain has a reasonable price, only financing more than 20M dollars. The team has been pursuing encryption fore several years already. The good code of the project is a good proof.
Relativity Theory of Openness
HashGraph has a committee of 39 authoritative agencies and organizations. Individuals are not eligible to join the committee. The committee is fully responsible for making all decisions. Dpos belongs to democratic centralism. There is a vote. There are elections. There is freedom. There is democracy. The HashGraph's committee belongs to the militaristic centralized tyranny rule.
A game of vested interests. Individuals do not have a chance.
Holochain is simple and simple. There is no such cumbersome and redundant committee organization. Everyone can purchase mining machine for mining. Rent your own computer resources to verify the entire network and jointly maintain the security of the network. An open and free public network does not require a cumbersome process.
Technical Relativity
HashGraph is a token trading engine based on the hardcoded consensus algorithm. Holochain is a DApp engine center on an agent-centric agent. Holochain will be more efficient than HashGraph, because HashGraph needs a consensus on everything. Even 99% of the data is non-competitive. HashGraph is relatively inflexible for building DApp applications. HashGraph does not have fragmentation. All nodes must handle all transactions.
From a technical point of view, HashGraph is also a very innovative and high-quality technology.However, Holochain is generally more suitable for establishing decentralized DApps.
Comparing Holochain and HashGraph from four aspects. Which one is the winner?
You should consider renaming the 'blockchain 3.0' part of the title; it is confusing for readers, as both hashgraph and holochain do not use a chain of blocks to maintain a unique proof of records containing transactions. Maybe you can change that part with 'next generation of distributed ledger technology'
