Making a SHA-512 of the complete download takes a long time, so instead we make a SHA-512 hash of every 1st MB block every 1GB. These hashes are then stored in a checksum file. The hash of that checksum file is stored onchain on the cosmos account as a memo. So in short you can verify the SHA-512 of the checksum file by looking up the transaction hash on-chain. Then you can use the checksum file to validate the download. A checksum.sh script is provided to do so.
Quicksync considerably improves the time it takes to re-sync nodes to the current block. We achieve this by creating various compressed archives that we deliver from high-performance services. The service is crucial for validators and other service providers who require fast deployments or quick recovery of existing services.
