In March 2023, the network suffered a protocol-level exploit in its Smart Contract Service that drained approximately $600,000 in liquidity pool tokens from three decentralized exchanges, requiring a full mainnet proxy shutdown for 41 hours. The platform operates under a council governance model comprising up to 39 global enterprises, which provides institutional stability but draws criticism for centralization relative to permissionless blockchains.","timeline":[{"date":"2016-01-01","event":"Swirlds, Inc. granted three U.S. patents protecting the hashgraph consensus algorithm invented by Dr. Leemon Baird.","source":""},{"date":"2019-09-16","event":"Hedera mainnet launched for open public access with HBAR as the native token.","source":""},{"date":"2021-09-15","event":"HBAR reached its all-time high price of approximately $0.57 USD.","source":""},{"date":"2022-01-19","event":"Hedera Governing Council voted to purchase the hashgraph intellectual property from Swirlds, Inc. and committed to releasing it under the Apache 2.0 open-source license.","source":""},{"date":"2022-08-05","event":"Hedera codebase transitioned to open source under Apache 2.0, completing the IP acquisition and open-sourcing commitment.","source":""},{"date":"2022-11-01","event":"Prolific scammer (account '2015717') allegedly began mass airdrop phishing campaigns targeting Hedera wallet users, sending fraudulent memos to tens of thousands of accounts.","source":""},{"date":"2023-03-09","event":"Attacker exploited a delegatecall precompile bug in Hedera's Smart Contract Service, stealing approximately $600,000 in tokens (DAI, USDT, USDC, WHBAR) from liquidity pools at Pangolin, SaucerSwap, and HeliSwap.
