Overview ¶
Package bootstrap checks for the bootstrap/fallback data update from the spacemesh administrator (a centralized entity controlled by the spacemesh team). This is intended as a short-term solution at the beginning of the network deployment to facilitate recovering from network failures and should be removed once the network is stable.
The updater periodically checks for the latest update from a URL provided by the spacemesh administrator, verifies the data, persists on disk and notifies subscribers of a new update.
Subscribers register by calling `Subscribe()` to receive a channel for the latest update.
