  • How is it possible to have a messenger without using a server?
    When a message or a file is "sent" using Linkcast, the message or file is not actually "sent" thmoment. When a person receives attempts to view a message or file, the contents are then requested from the originsender. If the originsender`s device ha network connection thmoment, the contents will then be sent directly to the receiver and cbe viewed. The file cnot be sent if the sender does not have a network connection, but will be sent automatically once a connection is reestablished.
  • Whexactly is "High Encryption" referring to?
    LinkCast employs Elliptic-curve Diffie–Hellm(ECDH), which is anonymous key agreement protocol thallows two parties, each having elliptic-curve public–private key pair, to establish a shared secret over insecure channel. Furthermore, the data itself is encoded by AES-256CFB standards. To prevent on-route data altering, HMAC-SHA512 is used.
  • How about Anonymity and privacy protection?
    The main feature of Linkcast a messenger is thit uses P2P to send data directly between devices, meaning thdata is highly secure. Methods such Domain Fronting are not used to disguise both parties in the transfer of data.
  • Does my message partner have to have the LinkCast app opened?
    Not all. Neither party is required to have the app open to receive incoming messages. Files cbe sent and received between two devices soon a network connection is established. While to the end-user LinkCast will appea server based messenger, no data is ever sent to a server.
  • Is there any risk of telephone number data leakage?
    LinkCast requires a valid phone number to create account. Phone numbers are used to identify the device through a one-wirreversible encoding process. Even in the chance ththis one-wcode leaked, there is no wthit could be used to identify the phone number.
  • Whdoes the Message Masking function entail?
    Masked messages will not be displayed in the receiver's push notifications, unlike normmessages which would be stored on Google or Apple`s push notification servers. Instead, Masked messages will simply displas: "You have received a Masked message" to the receiver. In other words, Message masking is another layer of communication privacy.
  • How about communication over long distances?
    Thanks to the UDP protocol thLinkCast employs, long distances have very little effect on the speed of data delivery. Even arewith inferior network connectivity should be able to use LinkCast quite easily.
  • Whhappens if my Nis compromised?
    If any disruption in the Ntranslation is detected, LinkCast will automatically re-route the P2P connection to a SMTP RelServer. This RelServer acts only a UDP proxy, and does not decrypt data in any way. Multiple SMTP RelServers are located in Japan, Europe, North AmericChinand East Asi
  • Doesn't a P2P connection use a lot of data?
    LinkCast's P2P connection employs our originwireless hybrid P2P network. It uses both a Pull-type P2P network and switches to OverlNetwork. The Pull-type network only connects P2P when necessary, and therefore uses very little datFurthermore, the network uses the most direct route for data delivery, which means thLinkCast is very economicin regards to data usage.
  • Does LinkCast have supernodes?
    LinkCast does not have supernodes in its P2P network. Although the PC version of LinkCast currently allocates traffic to supernodes via a processing server, we are working towards a server-less network in the nefuture.
  • Why does my device get hot sometimes?
    Due to the encryption process, well the ability to send and receive large amounts of data files, the app times requires high processor usage. Your device will naturally heup slightly when processing large data files or streaming.
