Open Access to Hedera’s Mainnet Beta Allows Any Developer to Build on Network

Dallas, TX — September 16th, 2019 — Hedera Hashgraph, an enterprise-grade public distributed ledger platform, today announced Open Access (OA) to its mainnet beta. OA allows anyone from the general public to create an account and any developer to build decentralized applications (dapps) on the Hedera Hashgraph platform. With hundreds of developers already building on the network over the last few months during its closed beta, the Hedera mainnet launches with 26 dapps and solutions now running live.

Amongst the dapps to go live on Hedera today are AdsDax, a decentralized advertising platform and marketplace, which has already conducted over two million transactions in 10 days on the Hedera network during live customer campaigns; Certara, a global, model-informed drug development and decision support leader, that is running a mirror node to provide insight on transactions on the Hedera network, with the ultimate goal of providing advanced analytics and demonstrate data provenance on health related transactions; and Chainlink, which will provide Hedera-based applications with reliable oracles and connectivity to off-chain data.

Mance Harmon, co-founder and CEO of Hedera Hashgraph, said, “Today we are thrilled that, through open access, dozens of decentralized applications are now live and running on the mainnet, along with mirror nodes and other parts of the ecosystem designed to expand Hedera’s reach and adoption. We thank these teams for being early supporters of Hedera, and are excited to see how each is making their own vision of a fairer, more secure and more distributed internet a reality.”

With Open Access, the Hedera Hashgraph network offers three services: 1) Cryptocurrency, throttled to 10,000 transactions per second, 2) Smart Contract and 3) File Service. Hedera’s smart contract and file service offerings are both currently throttled to 10 transactions per second. Hedera plans to increase speed methodically throughout the remainder of 2019, as part of a strategy designed to roll out network services in a measured and responsible way. The recently announced Hedera Consensus Service will be publicly available later this year and is expected to deliver similar performance and speed to Hedera’s cryptocurrency service.

Dr. Leemon Baird, Co-Founder and Chief Scientist of Hedera Hashgraph, said, “Today, we welcome developers globally to build decentralized applications on our platform, and are excited to see what they will build. With Open Access, our council members have also begun running nodes, marking the next step in our journey to become the industry’s most decentralized public network.”

The Hedera Governing Council governs changes to the software run by the Hedera distributed nodes, and brings stability and continued decentralization to the Hedera Hashgraph public ledger. Designed to comprise of 39 term-limited members at scale, from a variety of industries and geographies, a current list of council members can be found at
