S-PAY硬币成为S-PAY生态系统中的主要支付工具。然后可以在市场交易所购买S-PAY硬币或通过采矿赚取。例如,他们可以用来支付费用并获得信用卡。
由于潜在的PoS协议,S-PAY硬币不仅可以被全球每个用户用作支付,折扣或参与S-PAY生态系统的方法,而且每个S-PAY硬币所有者都可以使用&ndquo ;股份”的(&ndquo; save”)他的S-PAY硬币,从而每年赚取高达10%的利息。因此,它可以为自己的S-PAY硬币付出两倍的代价。
用“新”字样S-PAY,我们将完全改变人们使用加密货币的方式。 S-PAY不是使用大量不同的平台,而是通过一次注册从一个帐户访问所有相关服务。我们的客户将像使用欧元和美元等FIAT货币一样简单地进行加密货币支付。
我们的客户可以在系统内交换加密货币,实时付款,直接交换进入菲亚特货币或在ATM取款。甚至可以向没有加密货币钱包或S-PAY账户的人付款。
商家可以通过自动转换以加密货币或菲亚特货币获得货物和服务的付款,并消除汇率风险。公司可以使用S-PAY客户管理系统创建自己的支付系统,拥有自己的账户模型,费用和佣金结构,例如促进投资发展甚至提供贵金属存款账户系统给他们的客户。用例是无限的,每个公司都可以利用自己的企业形象。
全面的API支持自动批量支付–允许直接集成到公司自己的系统中。
一张自己的借记卡,将提供给所有商家和商业伙伴(白标,如果他们愿意,正在制作整个S-PAY服务完成。
Within the proof of stake (PoS) algorithms, an inequality is created/modified depending on the credit of a user's specific PoS cryptocurrency and not on the basis of block properties or calculations. Consider a user with address A and a balance of bal(A). Widely used PoS algorithms are based on these values using the following condition:
hash(hash(Bprev); A; t) ⩽ bal(A)M/D
where,
Unlike PoW (proof of work), the only variable that the user can change/influence is the time stamp t in the left half of the equation above. The credit of the active address is blocked by the protocol; e.g. The protocol can calculate the balance based on the deposits on this account that were not moved/transferred for one day. Alternatively, a PoS cryptocurrency may use undelivered transaction outputs, similar to Bitcoin; in this case the credit will be automatically blocked. A PoS protocol limits the possible values t can take. For example, if t is not allowed to deviate from the UTC time on the network nodes for more than 1 hour, a user cannot test more than 7200 possible values of t. Therefore compared to Proof of Work (PoW), no resource-intensive computing power is required.
Together with a valid address A and a sufficient time stamp t, the user must provide evidence of ownership to this address A. To accomplish this, the user can sign a newly generated block with his digital signature; in order to create a valid digital signature the user must own the address A private key.
The time to find a block for address A is exponentially distributed at the rate bal(A)/D. It follows that the use of Proof of Stake (PoS) is fair: the probability of producing a valid block equals the share of the user's credit in the total amount of coins in circulation. The time to find a block for the entire network is distributed at the rate ∑abal(a)/D.
Therefore, if the amount of available coins ∑abal(a) is fixed or increases at a predictable rate, the difficulty D should be known in advance:
where Tex represents the expected time between blocks. In practice, D must be adjusted based on the last blocks since not all users/ coin owners participate in block mining.
