3. Question about the Sia System

Question about the Sia System

  • 2

    Hi there so I have a bunch invested in SiaCoin and really like the idea/team/website, was just wondering if you could help me with a concept that has been bothering me.

    Say you have distributed a bunch of data using SiaCoin over the network to be stored in various locations, then isn't there a high risk that one of the locations could go offline (and never come back online) which means you are never able to access the data stored on that location that went offline...?

    Thanks
    Steve

    Every bit is stored on 30 different servers. If one goes down, you're not impacted. If 10 go down, you're not impacted. If 20 go down, you're still not impacted. I think your renter will even start re-uploading the file to new hosters once >10 of your hosters went down, to come back closer to 30 hosts again.

    Note that files are not necessarily stored as one, instead they may be split up to reasonably sized chunks, and this applies to each of the junks.

  • Hi 24Caliber...
    Take a look at Taeks very good write up on hosting: https://forum.sia.tech/topic/1037/the-hosting-handbook
    THe way sia works when uploading data is, the data is split into little chunks encrypted using the key only you know, and distributed to a number of hosts that effectivly do not know what content they host. not only once but is duplicated a number of times. As you say hosts come and go (the whole story about "collatteral" is thought of to incentify hosts to STAY online by having sia cons at stake in the event they do not fullfill the renting contract). However if hosts do get off line, the SIA protokoll will take care of a new re duplication so the data is always kept intact - it is clever thinking :-)

    Thanks for the detailed and fast responses Maol and Larsfloe: All the systems seem to be very clever thinking on the blockchain...bit over my head, or at least, I try not to go too deep down the rabbit holes (although do like to know what I am investing in!).

    OK I will take a look at the handbook.

    30x duplicate sounds like a lot...although secure, is that very efficient for resources?
