🚀 F3 IS LIVE ON FILECOIN MAINNET! 🚀
⚡ As of epoch 4919580, the F3 manifest has been locked in, and the Bootstrap phase is complete. Finality is now just a couple of minutes away – a huge step forward for the Filecoin network 🕒⚡
📢 Please upgrade to the new patch release **Lotus v1.32.3 or s**et
F3_INITIAL_POWERTABLE_CID="bafy2bzacecklgxd2eksmodvhgurqvorkg3wamgqkrunir3al2gchv2cikgmbu"to ensure that the F3 initial power table CID is correctly set in your Lotus node. Read more here.📢💪 This moment is the result of nearly two years of research, testing, iteration, and community collaboration. With F3 now running on mainnet, transactions are confirmed faster, operations are streamlined for SPs, and we're laying the groundwork for a new generation of dapps and cross-chain integrations. 🤝
🙏 Huge thanks to everyone who contributed to making this a reality – implementers, testers, node operators, SPs, and curious minds who followed along on the journey!

🚀 This is just the beginning. Let’s keep pushing what’s possible together 💙 #fil-fast-finality
F3 is now active on mainnet. Node operators should set the initial power table CID so that they don’t need to rely on past blockchain state to compute this. Failure to do so will cause nodes without historical state leading up to the bootstrap epoch 4919580 (2025-04-29T10:00:00Z) to drop from participating in F3.
