On August 24, 2018, the Hedera mainnet came to life — a ledger governed not by anonymous miners but by a rotating council of some of the world's largest institutions. Eight years later the network is still here, still finalizing transactions in seconds for fractions of a cent, and still answering the same question it started with: what if enterprise governance and a fast consensus algorithm were combined from day one?
This week marks the eighth anniversary of that launch, so here is the story in eight chapters — one per year, roughly — ending with the live numbers you can check on our HBAR Pulse dashboard right now.
Hedera Hashgraph the company was founded in 2017 by Leemon Baird, inventor of the hashgraph consensus algorithm, and Mance Harmon. The mainnet that launched on August 24, 2018 was unusual from the start: instead of a proof-of-work chain, it ran hashgraph's asynchronous Byzantine fault tolerance (aBFT) — the highest formal security grade for consensus — across a council of governing members rather than open validators. Skeptics called the council model centralized. Eight years on, that same model is what institutions point to when they explain why they chose Hedera.
For its first year the network ran in restricted mode while the platform hardened. Open access arrived on September 13, 2019, when anyone could finally create an account and transact. The earliest public transactions are still on record via the Hedera Mirror Node API — the first ones carry a consensus timestamp of September 13, 2019 and fees of a fraction of a cent. That fee floor, roughly $0.0001 for a transfer and capped by design, has remained one of Hedera's signature promises.
In 2021 the Hedera Token Service (HTS) went live, letting projects mint native tokens at the protocol layer — no smart contract required — with built-in compliance controls like KYC and freeze keys. Native minting made Hedera instantly attractive to stablecoin and asset-tokenization pilots, a direction the network never really left.
The 2022 upgrades delivered Smart Contracts 2.0: full Ethereum Virtual Machine equivalence, meaning Solidity developers could deploy existing contracts with minimal changes and use familiar tooling. That single change unlocked the DeFi era on Hedera, because it lowered the porting cost for every team already building on Ethereum tooling.
HTS tokens with metadata became Hedera's NFT standard, and 2022 brought a burst of collections, marketplaces, and community energy. Like NFT cycles everywhere, the froth cooled — but the rails stayed, and today they power everything from collectibles to event tickets to tokenized real-world assets.
SaucerSwap, the network's homegrown DEX, matured from its V1 AMM to V2 concentrated liquidity and then a V3 central limit order book with limit orders and depth. By July 2026 the protocol reported $6 billion in all-time volume across more than 19 million trades (SaucerSwap docs). If you want to watch that flow live, our War Room and Swap Leaderboard visualize it continuously.
Hedera's quietest chapter may be its most important: regulated asset tokenization. abrdn, the UK's largest active asset manager, tokenized a money market fund on Hedera via the FCA-regulated exchange Archax — real fund shares, not a demo. The council itself — abrdn, Deutsche Telekom, IBM, Google, Dell and others over the years — turned from a talking point into a distribution channel for exactly this kind of work.
The most recent chapter is the one HBAR holders know best. The Canary HBAR ETF (ticker HBR) launched on Nasdaq on October 28, 2025 — the first US spot HBAR fund. In August 2026 Grayscale withdrew its own Hedera ETF filing (Form RW, August 7, on SEC EDGAR), which we cover in detail in Grayscale Hedera ETF Withdrawal Explained. One issuer in, one out — but the door to US-listed HBAR exposure is now open, and it did not exist at any prior anniversary.

When did Hedera launch?
The Hedera mainnet went live on August 24, 2018. Open access — when anyone could transact — followed on September 13, 2019.
When was Hedera founded?
Hedera Hashgraph, the company, was founded in 2017 by Leemon Baird and Mance Harmon; the hashgraph consensus algorithm predates the company.
How old is Hedera?
As of August 2026, the mainnet is eight years old and open to the public for almost seven.
What has stayed the same for 8 years?
The fee floor (fractions of a cent, capped), 3–5 second finality, aBFT security, and the fixed 50 billion HBAR supply.
Eight years in, the network's pitch is remarkably close to 2018's: fast, fair, cheap, enterprise-governed. What changed is everything built on top. This article is historical context, not financial advice — nothing here is a recommendation to buy or sell HBAR.
