 This EIP divides the cross-chain ecosystem into 3 layers and defines the SendPort contract and IReceivePort interface at the foundational layer. The implementation of the other layers is left to ecosystem project participants.

 Under this EIP, an official SendPort contract is deployed on each chain as a unique entity. It is responsible for collecting cross-chain messages on that chain and packing them. SendPort operates as a public, permissionless, administrator-free, and automatic system. Cross-chain bridge operators retrieve cross-chain messages from the SendPort and transport it to the target chain to complete the cross-chain messaging process.

 The essence of cross-chain is to inform the target chain about events happening on the source chain. This process can be divided into 3 steps. The following diagram illustrates the overall principle:

 Upon the completion of packing a new MerkleTree, the package carrier (usually the cross-chain bridge project) pulls the root from multiple chains and stores it in the IReceivePort contract of each chain. It is important to note that the traditional approach involves using a push method, as depicted in the following diagram:

 If there are 6 chains, each chain needs to push to the other 5 chains, resulting in the requirement of 30 cross-chain bridges, as shown in the diagram below:

 When N chains require cross-chain communication with each other, the number of cross-chain bridges needed is calculated as: num = N * (N - 1).
 
 Using the pull approach allows the batch of cross-chain messages from 5 chains into 1 transaction, significantly reducing the number of required cross-chain bridges, as illustrated in the following diagram:

 If each chain pulls messages from the other 5 chains onto its own chain, only 6 cross-chain bridges are necessary. For N chains requiring cross-chain communication, the number of cross-chain bridges needed is: num = N.
