Coda Daemon Beta 2

Installation

See Getting Started section of our docs for instructions!

Changelog

• Improved coda client status output to be cleaner, and have formatted properly values (#3010)
• P2p layer attempts to reconnect to nodes that drop off every so often (#3005)
• Nonces can be specified and increment properly even before a block has been sent (#3021)
• Fixed the too many open files issue (#3056)
• Fixed an issue with retrying bootstraps (#3099)

We also merged in 4 weeks of code from master that was being developed while we hardened the release branch. Hence a lot more commits than usual:

• Incremental ledger catchup (#2842) - catchup is more efficient because it gets data from more than one peer, and doesn’t rely on a monolithic request
• Better logging (#2977, #3002, #3054, #2939)
• Commit transactions to SNARKed ledger in a batch when moving root (#2944)
• Refactored Snark work system (#2847)
• Switched over to Bowe-Gabizon Snark from Groth-Maller (#2755)
• and more...

Coda Daemon Beta 1

Changelog

• Initial beta release 🙌

Known Issues

• Kademlia child dies — mitigation: Restart your node. If that fails, restart your computer. This seems to be non-deterministic.
• Unattached mask — mitigation: Add your logs and your visualization to our issue, and then restart your node. #2969
• Excessive status logs in daemon whenever you run coda client status. #2968
• coda -version gives bad information -- mitigation: Use coda version instead. #2971
