func (PersonalAddress) ConvertToOriginInfo 

func (address PersonalAddress) ConvertToOriginInfo() OriginInfo

type PublishTorrentTrans 

type PublishTorrentTrans struct {
	Torrent TorrentFile
}

PublishTorrentTrans represents a transaction that shows a node/user posting a new torrent onto the blockchain This allows other users and nodes to discover what layers comprise what type of file or content, so that the individual layers can be directly/"privately" requested from nodes (users don't request layers on the blockchain)

func (PublishTorrentTrans) GetRawBytes 

func (tt PublishTorrentTrans) GetRawBytes() []byte

func (PublishTorrentTrans) ToString 

func (tt PublishTorrentTrans) ToString() string

type RepMessage 

type RepMessage struct {
	WasValid     bool
	HighQuality  bool
	AccurateName bool
}

RepMessage represents a message that conveys the quality of a Torrent, in terms of the accuracy of the name, the validity of the file itself (does it form a cohesive file that runs/opens as expected?), and if the content itself is high quality

type ReputationSummary 

type ReputationSummary struct {
	//Reputation of all torrents, indexed by their hashes
	TorrentRep map[string]TorrentRep

	//Reputation of all layers, indexed by hash
	LayerRep map[string]LayerRep
}

func (ReputationSummary) ToJSONSummary 

func (summary ReputationSummary) ToJSONSummary() JSONRepSummary

	SharedLayerHash string
	Recipient       Base64Address
}

SharedLayerTrans represents a transaction that shows a node sharing a torrent layer with a particular address This can be used by other nodes to see if a node has indicated sharing with an address, and whether or not that address left feedback on the share, if that address actually received the layer, etc.
