Hedera Consensus Service whitepaper

Hedera Services: Cryptocurrency, Smart Contracts, and Files Service

Third-party applications building on Hedera

Hashgraph consensus is asynchronous byzantine fault tolerant (ABFT) and transactions have fairness on ordering, timestamps, and access

Hedera Services are also asynchronous byzantine fault tolerant (ABFT) and have transactions with fairness on ordering, timestamps, and access

Timestamping and revocation real-world use cases

Smart Contracts Service

Hedera Consensus Service allows you to run your service at the speed of a native service and adopts the properties of ABFT and fairness on ordering, timestamps, and access

Scaling a distributed ledger technology (sharding, side ledgers, and consensus service)

Intro

What is hashgraph?

How fast is hashgraph?

How secure is hashgraph? What does asynchronous byzantine mean?

How fair is hashgraph? (Fair access, fair ordering, & fair timestamps)

How does the hashgraph algorithm work?

What incentivizes individuals to gossip?

Gossip protocol, the fastest most resilient way to get a message out.

How does hashgraph prevent double spend?

Consensus for free with math guarantees - gossip about gossip.

How does the number of hashes scale with the number of nodes in the system?

Can hashgraph be used for a public ledger on a large scale?

When pitching this technology to enterprises, how do you differentiate hashgraph from traditional blockchain?

What is the target market that would benefit from hashgraph?

What is next for hashgraph and why haven't traditional blockchain technologies deployed gossip about gossip or virtual voting?

How does hashgraph differ from conventional blockchain and how do you get enough users on board for the system to function properly?

Proof of work and forking.

There are 51% AND 34% attacks on any blockchain/DLT.

How would the cost of a 51% attack differ from a 34% attack?

What kind of transactions per second has hashgraph achieved?

Will there be an ICO?

What is your main product and business model?

Are smart contracts possible?

Will hashgraph swallow up the competition?
