Hedera Hashgraph Continues Global Expansion With Apac Leadership Announcements

Hedera Hashgraph Continues Global Expansion with APAC Leadership Announcements

Jan 29, 2019Hedera Team

Singapore — January 30, 2019 Hedera Hashgraph, a next-generation public ledger designed to have highly diversified governance and the most distributed consensus at scale, today announced the continued expansion of its APAC operations. Hedera now has a presence in Singapore, Korea, and Japan.

Transaction Confirmation Methods In Hedera

Hedera Technical Insights: Transaction Confirmation Methods in Hedera

Jan 24, 2019Paul Madsen

After a client submits a transaction to Hedera, the client may seek confirmation that the transaction was added to consensus state and also to perhaps retrieve information associated with that addition. As an example, if the transaction is a transfer of hbars for the purchase of a coffee, then the coffee shop will likely want confirmation that its account received the customer’s payment before pouring the brew.

2018 Hedera Hashgraph Year in Review, and a Look Ahead

Jan 18, 2019Mance Harmon

What an amazing year it has been. Looking back on all that we have accomplished, and how far we have come in 2018, we are grateful and continue to be inspired by the ongoing support we receive from the Hedera community. In 2018 we made substantial progress on our platform, raised funding to sustain the business for years to come, and have formally engaged so many organizations that have chosen to use Hedera to solve real-world problems.

Hedera Technical Insights: A hybrid DLT architecture for gaming

Jan 11, 2019Paul Madsen

Online gaming architectures have historically relied on an intermediary to facilitate the game play — running centralized servers to which users would connect in order to find opponents and then managing the game state (e.g. where all characters are in a Massively Multiplayer Online (MMO) game, or how much gold each has, or where the pieces are in chess).

Community Testing Program 1

Hedera Hashgraph Launches Mainnet Early Access Program

Dec 18, 2018Hedera Team

Dallas TX – Dec 18, 2018 – Hedera Hashgraph, a next-generation public ledger designed to have highly diversified governance and the most distributed consensus at scale, today announced the launch of its initial community testing program. The first phase of the program allows developers and the community to test the mainnet and testnets, and earn up to 1,000 hbars, Hedera’s native cryptocurrency, for testing the network and developing third-party applications.

Hedera Technical Insights: Code is law, but what if the law needs to change?

Dec 05, 2018Paul Madsen

Distributed Ledger Technologies (DLTs) commonly have simple and inflexible forms of immutability. Hedera supports a more flexible form of controlled mutability, which allows certain changes under certain circumstances, but prevents other types of changes. One area where this is particularly important is for smart contracts.

These Hedera SDKs are so freakin’ cool

Nov 13, 2018Ken Anderson

We’re still so early in this journey we call Hedera Hashgraph. We just started opening up testnets to a wider audience of developers and boy did we learn some really cool things…things that have informed how we want to build our SDKs. Frankly, we need to make sure that developers absolutely love the SDK experience. So we’re getting smart and fun about building our SDKs with the help of those very same developers.

Hedera Technical Insights: Fragility in DLT

Nov 08, 2018Paul Madsen

Some consensus algorithms are fragile — they cannot adapt to changes, either in the membership of nodes, or in the influence of those nodes towards consensus. The result is that such changes cause consensus to be prevented or corrupted. This can be a problem for some types of distributed ledgers, but it is not a problem for Hedera.

Formal Methods: The Importance of Being ABFT in a World with Bad Actors

Oct 29, 2018Hedera Team

The highest security standard for consensus algorithms is known as Asynchronous Byzantine Fault Tolerance (ABFT). The hashgraph algorithm, as used in the Hedera public ledger, achieves this gold standard, with a mathematical proof that it is ABFT. This proof-of-stake consensus system was first proved to be ABFT in a rigorous math proof published in 2016. That proof has now been verified by computer in a formal verification completed by a Carnegie Mellon University professor — and we think it is important to explain what that means.
