SnapShot Mainnet updated every 5 hours

You can check the size and time of snapshot creation with this command curl -sI https://server-1.stavr.tech/Mainnet/Regen/regen-snap-1.tar.lz4 | grep "last" && curl -sI https://server-1.stavr.tech/Mainnet/Regen/regen-snap-1.tar.lz4 | grep content-length | awk '{printf "%.2f GB\n", $2/1024/1024/1024}'
