type AppLayer ¶

type AppLayer struct {
	types.Application
	Sh         *shell.Shell
	Validators []Validator
	Evs        EventChan
}

The Application layer that filters passed transactions for validity. Transactions are formatted as:

tx := []byte(  IpfsHash + "/" + EncryptionPassword  )

Upon validation, the layer pulls the vidshare-object from IPFS, and validates it (including the decryption password). Aside from existence and parse-validity, the metadata passes through an array of validators (.Validators-field) which can decide, whether a media object is Valid or not.

Finally, if passed, it (optionally) sends the ipfs-hash, metadata and password through an event channel so that another thread (or agent) can perform further processing asynchronously.

There is one potential source of Non-Determinism: It uses IPFS.
