 CADT relies on all participants publicly sharing their data over Chia Datalayer, which includes sharing the Chia-generated `.dat` files over HTTP.  The files are located in `~/.chia/mainnet/data_layer/db/server_files_location_<NETWORK>/` (where `<NETWORK>` is the Chia network, usually either "mainnet" or "testneta") and can be shared over any web-accessible HTTP endpoint, including

Datalayer-http runs on port 8575 by default which may need to be opened in your firewall configuration or forwarded by your router.  Additionally, a static IP address will be required, which is not offered by default on many hosting providers.  On AWS, assign an Elastic IP to the EC2 instance or use an Application Load Balancer to solve this.

-* Use [S3](https://aws.amazon.com/s3/) or other object store.  Datalayer .dat files can be synced to any cloud file storage solution that can serve them publicly over HTTP.  Chia installs with a [plugin that natively integrates with S3](https://docs.chia.net/guides/datalayer-permissions/#the-chia-s3-plugin), but it requires all participants to have an AWS login, which is not appropriate for the public nature of CADT.  To use S3 to serve .dat files publicly, [use this script and follow the installation and usage instructions in the README](https://github.com/TheLastCicada/Chia-Datalayer-S3-Sync).
