Symbiosis  protocal 基于稳定币的跨链兑换协议.

Symbiosis protocol  组成结构：

Symbiosis Protocol V1  实现原理：

      Scheme 1. Ethereum — BNB liquidity pool {sUSDC, BUSD}.

 

Scheme 2. Nerve-like liquidity pools with {stablecoin <> sToken} pairs in the Symbiosis Protocol V1.

Symbiosis Protocol V2

 

 Scheme 3. Symbiosis protocol V2 with Octopool.

Cross-chain operations via V2

 

Case 1

 

The source and destination blockchains of a cross-chain operation are not S-Chain.

 

As an example, let's see how a cross-chain swap MATICs for AVAXes goes with Symbiosis V2 (Scheme 4).

 

 

Scheme 4: A cross-chain swap MATICs for AVAXes with Symbiosis protocol V2

 

Case 2

 

The destination blockchain of a cross-chain operation is S-chain.

 

As an example, let's see how a cross-chain swap MATICs on Polygon for BOBAs on BOBA BNB goes with Symbiosis V2 (Scheme 5).

 

 

Scheme 5: A cross-chain swap with Symbiosis protocol V2 (MATICs on Polygon for BOBAs on BOBA BNB).

 

Case 3

 

The source blockchain of a cross-chain operation is S-chain.

 

As an example, let's see how a cross-chain swap BOBAs on BOBA BNB for AVAXs on Avalanche goes with Symbiosis V2 (Scheme 6).

 

 

The Symbiosis relayers network (关键点  the key component)

1.  分组.
2.  每接收到一个交易都会生成独有的私钥和签名. 
3.  每组去处理不同的交易签名请求， 组内部进行3/2共识，并选出leader发送交易.
4.  经济激励刺激
