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).
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.
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.
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.
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.
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.
Dallas TX – Oct 18, 2018 – Hedera Hashgraph, a next-generation distributed public ledger with highly diversified governance, today announced the winners of the Hedera18 global hackathon, plus seven regional winners and the inaugural Hedera MVPs. Hedera today also announced the launch of hashgraph.org, a free educational resource to the hashgraph community.
Dallas TX, Hedera18 Developer Conference – October 17, 2018 – Hedera Hashgraph, a next-generation distributed public ledger with highly diversified governance, today announced that the hashgraph consensus algorithm has been validated as asynchronous Byzantine Fault Tolerant (ABFT) by a math proof checked by computer using the Coq system.
Dallas TX – Oct 10, 2018 – Hedera Hashgraph, a next-generation distributed public ledger with highly diversified governance, today announced the public release of the Hedera SDK in Java. The SDK is open sourced under an Apache 2 license, and can be found at github.com/hashgraph/hedera-sdk-java. With the SDK, developers can now begin to develop Hedera-based applications for use on the Hedera platform.
