Sky System layout spicy big, or first look at sky and consensus it.

Sky Coin/sky is a very old-style project, the current market value ranking in about 100, its liquidity is very small, only 10%, the remaining tokens are mainly used to motivate, so that the whole system of sky can be good, vigorous development.

Sky the whole system is more complex, its ecology contains all aspects of the product, using a picture to understand the sky ecology

The above architecture is supported by five core components of sky

Skycoin: Fast, secure currency supported by bandwidth.

SkyWire: A truly centralized mesh network.

Skyminer: Implements the hardware facilities of the real skywire mesh network.

Fiber: An open, de-centralized blockchain network.

Skysuite: Distributed Application Suite.

From the various products to the target of a variety of products, you can see that Sky wants to do the ecology is very large, there is the skycoin of the standard Bitcoin, there is a standard Ethereum smart contract CX, there is a CXO distributed storage, by the standard Internet system SkyWire, As well as the Sky-messenger and BBS for mobile communication and design communication.

So it is not only a currency, because I rarely write money (mainly feel that there is nothing to write about), as if only a stable currency dai,dai or more complex, can write more content.

First look at the characteristics of skycoin, and how these characteristics are achieved, of course, these characteristics and their use of the consensus algorithm is of great relevance.

1, fast, 2 seconds to complete the transaction;

2, 0 handling fee, transaction consumption of coins, is a kind of holding skycoin and free of charge to obtain tokens;

3, security, set up on the Golang, not affected by 51% attacks, reversals, duplication and other threats;

4, privacy, can mix multiple transactions together to ensure that the transaction can not be differentiated;

5, sustainability, no computing needs, mobile phone processor can be run;

6, incentive, the user through the SkyWire system to provide resources to earn the substitution of money, you can also use tokens to pay access to network resources;

7, physical support, based on the provision of resources to obtain tokens of the use of the scene, means that the skycoin with physical asset support, that is, bandwidth.

From the overall view of sky innovation is relatively large, and the general product has a large difference, such as its use of the consensus system is not common POW, POS, dpos and other mainstream consensus algorithm, but obelisk this new and stronger novel algorithm.

The more typical of the algorithms that are proven to be highly available are the POW and POS (Dpos and POS, which are transformed on top of the POS, are similar, not mentioned), and both have their own distinct characteristics, in a simple comparison.

POW's energy consumption, has always been the focus of debate, not to deny the meaning of the POW, from the overall and long-term considerations, the power of the POW is really too much, there is also the general project can not support the POW, not what projects are willing to pay the cost of mining machine to dig mine.

POS in fact quite in line with the form of shareholders, holding tokens is a shareholder, more shares have more voting rights and dividend rights, which is a more consistent with the traditional model of the algorithm, the centrality of risk is relatively high, and the blockchain to the central spirit is not quite consistent.

So sky does not choose these mainstream algorithms, but uses the obelisk distributed consensus algorithm.

Obelisk internal node is made up of ordinary computer or Sky system hardware Skyminer composition, do not need a special mining machine, each node can subscribe to other nodes of their own trust, the more subscriptions, the greater the impact of the node.

Each node has its own personal blockchain (this should be achieved through the fiber of the sky system, fiber is an open de-centralized network, can be customized blockchain), node operation will be recorded on the individual blockchain, you can easily audit the node, to prevent all kinds of things that affect the security of the system to occur , such as cutting off nodes and network connections.

And the IP address of the node is exposed only to the node to which it subscribes, there is no fixed port, and there is no known plaintext in the wired format.

There are two kinds of nodes in the obelisk system, namely the block node and the consensus node, the block node is responsible for validating the transaction and packing block, the consensus node is responsible for acquiring all the blocks and building new blocks, and the new blocks are generated according to certain rules.

Some features

In the obelisk system, the calculation cost is very low, does not need to undertake the responsible computation to compete the block right, therefore is one kind of low energy consumption consensus mechanism.

Nodes can be trusted to connect, and because the node has a separate blockchain, the review of the node is very easy, and the malicious node to clear out the network, the nodes will form a trust network, which will increase the security of the system.

And each node a blockchain and IP hiding and other design, also take into account privacy.

Since tokens are not mined, there is no threat to POW and POS, and as an established project, the security of its token storage has been proven in its recent crisis.

Ms. Li, blockchain practitioners, 007er, peer to the major portal column author, fund practice, securities practitioners, individuals, Weimuzimuke, willing to work with you to progress together.

Pull a small group, chat, regaling, common learning, common progress, may be able to provide some value information, perhaps not, interested can add me, send 2.8 yuan red envelopes into the group.
