Obelisk:

Each Obelisk node (Skycoin Consensus Node) has a public key (an identity) and personal blockchain (a public broadcast channel). Consensus decisions and communication happen within the personal blockchains of each Obelisk node. This is a public record of everything a node does. This allows the community to audit nodes for cheating and collusion. It gives the community a way identify nodes which are participating in attacks on the network and it makes public how decisions in the network are being made and which nodes are influencing those decisions.

Each node has a list of other nodes that it subscribes to. Nodes with more subscribers are more "trusted" and yield more influence in the network. If the community does not trust the nodes representing them or feels that power within the network is too concentrated (or not concentrated enough) the community is able to collectively shift the balance of power in the network by collectively changing their trust relationships in the network.

Node subscription relationships can be random and/or can be formed through web of trust (subscribe to nodes of people you know and people in community you trust).

When a node receives a new block from a chain it is subscribed to, it publishes the hash of the block it publishes. This is a public acknowledgment of the receipt of the block. Each block is timestamped and counter references blocks from other chains. This creates a dense interlinked chains of block acknowledgments. These chains establish causal relationships and can act as a distributed time stamping system as described in the next section. This allows the network to prove that data did not exist or was not published to the network or establish that particular nodes were active or offline during a particular time interval.

The current Obelisk consensus algorithm is based upon Ben-Or's randomized consensus algorithm.

A Sybil attack in a random graph (worse case) allows the Sybil nodes to control consensus, but the nodes are unable to revert transactions, removing the only economic incentive to attack the network. In real world graphs the Sybil resistance of the network is actually very high and running a node is moderately costly in terms of bandwidth, which make large botnets prohibitive.

Trust relationships are scarce and can be rescinded. In the event of an attack, the network reacts by severing connections to less trustworthy nodes and contracting to a smaller core of trusted nodes. The public record left by each node's personal blockchain makes it very easy to identify the nodes participating in an attack. As attacking nodes are identified individuals sever relationships with those nodes, reducing their influence.

    Skycoin consensus is democratic and nodes are run by the community.
    Skycoin node consensus is public
    Every node is accountable to the community and 3rd party audits.
    Influence within the Skycoin consensus system is democratic and transparent (but unequal).

can tell you one thing.you should invest in something you know about and read about. it will sync just leave you computer. and the price will stabilizes. 

Took me around 3 hours to sync the wallet after downloading it. It's not that bad.

Like I said, I bought siacoins as a long term investment, so I was not planning to sell, but I don't know if it's normal that the wallet sync takes sooo long, and I think that's not good for a plataform that I guess that wants to become popular.

And if I wanted to sell because the price was dropping too much and I could potentially lose a lot of the money I invested, I just wouldn't be able to do it, and I think that Sia should warn everybody that transactions/balances are not available until the sync is completed, and that said sync can take DAYS to be completed, that way I would have been warned to not send my siacoin to the wallet until the sync was completed, and I guess everybody would like to know something like this before using the Sia plataform/wallet.

I downloaded the wallet because I invested in Siacoins and wanted to keep them safe, but if I was a casual user that wanted to check how Sia worked and I saw how long it takes to properly work, I don't know if I would have the patience to wait for so long for the sync. I don't know the technicalities behind this, I'm just saying that something like this should be worked out to avoid losing potential new users.

just take a chill pill. Btc is rising so fast now. And other coins hard to keep up. It will go back to normal! Probably its better for you. That you did not have chance to sell.

Yeah, was this the great news coming this friday or is there something else? Price is going down right now.

EDIT: And I can't do anything with my siacoins because I sent them to the wallet when I installed it and it's taking an eternity to synchronize so I can't see my coins or send them anywhere else, how is it possible that it takes so long? 

I was planning to hold for a while, but if I wanted to sell before the price goes lower, I just couldn't because the wallet is the slowest cr*p I've seen in my life. I don't know the reasons for this, but the devs should definitely work on it if they really want that Sia becomes a truly popular plataform, I can see lots of people thinking "f*** it" and uninstalling it after checking how incredibly slow it is.

WHy is the coin being dumped like that?
Such bad news or what?

ASIC mining rig is a great news!

Agreed. Also, I thought the news was not until Friday - so maybe this is just a foundation for future announcement?

I don't think ASIC mining is a great idea look at bitcoin and all the large mining operations that control everything. I thought their announcement was a technical one with cool features, very disappointing news.

Confused.  ASIC for mining only SIA?  Why?  People are speculating the ASIC miner will have more of a role in the storage infrastructure.  As a GPU miner, not sure what to feel tbh.

What do people think about this announcement?

The Obelisk SC1 – the first ASIC built for Sia mining.

What a sad day, Sia's marketcap is x10 times higher than Storj   

Sia soon, I think, will rise up...
