FORSAGE（佛薩奇）系統開發，公排佛薩奇2.0原始碼開發搭建

 　基本運算與加法電路

 

 半加器

 

 兩個二進位制數（A和B）相加，最低位會產生兩個結果，分別是和（S）和進位（C）,能夠實現一個二進位制位加法運算的電路即半加器，半加器可以這樣設計閘電路（根據A、B相加後的運算結果）：S=A⊕BS=A⊕B,C=ABC=AB

 

 全加器

 

 將A、B、C一同運算產生S和新的進位C稱之為全加器，全加器和半加器統稱加法器，全加器相互串聯即構成了二進位制數的加法運算，常見的8位、16位、32位、64位為CPU的暫存器位數，不要混淆為加法器的個數（也和匯流排位數有關）。

 

 現在一個CPU中含有的加法器個數非常巨大。

 基本運算的實現（二進位制）：

 減法：由加法計算A和B的補碼即為減法

 乘除法：由移位實現

 Compared with traditional contracts,smart contracts with the three characteristics of blockchain have the following advantages:

 1.Trust.

 As the smart contract is based on the blockchain,the contract content is open and transparent,and cannot be tampered with.Code is law.Based on the trust of code,traders can trade safely and safely in a distrustful environment.

 2.Economical and efficient

 Compared with traditional contracts,disputes often arise due to differences in understanding of contract terms;Smart contracts can avoid differences well through computing language,rarely cause disputes,and the cost of reaching consensus is very low.On the smart contract,the arbitration result comes out and takes effect immediately.Therefore,compared with traditional contracts,smart contracts have economic and efficient advantages.
