Introducing SteemData Notify
July 05, 2017
## Email and Telegram Notifications *SteemData Notify* is a free blockchain monitoring service, that sends you (the account owner) Email and Telegram notifications when Payments and critical Account Changes occur. ### Example use case Alice has $10,000 SBD in her savings wallet. Unfortunately, Alice trusted a 3rd party app with her Active key in the past, and this app got hacked recently. Alice is on her summer vacation, and doesn't monitor her Steemit web wallet on a daily basis. Meanwhile, the hacker triggers a 3 day process of withdrawing the $10,000 SBD from savings, with the intent of stealing it. Fortunately Alice uses *SteemData Notify*, sending her immediate notification, which alerts her to cancel the withdrawal, and change her keys, locking the hacker out. ## Dust payment based Authentication Every change of settings on your account in *SteemData Notify* is authenticated by a dust payment to @null, containing an unique hash as a memo. The memo hash is derived from a cryptographic signature of the serialized settings object. This ensures that the account owner has authorized a precise and verifiable change. Furthermore the integrity of settings in the *SteemData Notify* database can be verified at any time. Your private keys are never exposed to any 3rd party in this process.  ## Try it: [notify.steemdata.com](https://notify.steemdata.com/) ------- *Please note that SteemData Notify is a free service, provided on an as-is basis, with no guarantees of uptime or correctness.
