1. 引言

Polygon zkEVM节点可提供如下服务：

1）synchronizer服务：所运行zkEVM节点必须运行的基础服务，其它服务均需依赖于synchronizer服务。负责在L1与L2网络间同步数据。
2）eth-tx-manager服务
3）sequencer服务：用存储于Pool数据库中的交易构建new batches。
4）sequencerSender服务
5）RPC服务：将交易relay给Trusted sequencer。
启动脚本可为：/app/zkevm-node run --network custom --custom-network-file /app/genesis.json --cfg /app/config.toml --components rpc --http.api eth,net,debug,zkevm,txpool,web3
依赖：
- synchronizer服务
- statedb数据库
- rpc数据库，即pooldb
- Prover所提供的Merkle Tree和Executor服务
6）aggregator服务：作为Prover的服务端，接收Prover连接请求，负责为待证明batches 生成proofs。
7）l2gaspricer服务

Polygon zkEVM节点RPC服务所支持的JSON RPC endpoints与以太坊节点的有所不同，当前支持的JSON RPC endpoints有：

1）对应debug api有：【debug endpoints表示相应接口未经深度测试】【对应endpoints_debug.go内各函数】
- debug_traceBlockByHash
- debug_traceBlockByNumber
- debug_traceTransaction

2）对应eth api有：【对应endpoints_eth.go内各函数】
- eth_blockNumber
- eth_call
  - doesn’t support state override at the moment and pending block. Will be implemented #1990
  - doesn’t support from values that are smart contract addresses. Will be implemented #2017
- eth_chainId
- eth_estimateGas * if the block number is set to pending we assume it is the latest
- eth_gasPrice
- eth_getBalance * if the block number is set to pending we assume it is the latest
- eth_getBlockByHash
- eth_getBlockByNumber
- eth_getBlockTransactionCountByHash
- eth_getBlockTransactionCountByNumber
- eth_getCode * if the block number is set to pending we assume it is the latest
- eth_getCompilers * response is always empty
- eth_getFilterChanges
- eth_getFilterLogs
- eth_getLogs
- eth_getStorageAt * if the block number is set to pending we assume it is the latest
- eth_getTransactionByBlockHashAndIndex
- eth_getTransactionByBlockNumberAndIndex * if the block number is set to pending we assume it is the latest
- eth_getTransactionByHash
- eth_getTransactionCount
- eth_getTransactionReceipt * doesn’t include effectiveGasPrice. Will include once EIP1559 is implemented
- eth_getUncleByBlockHashAndIndex * response is always empty
- eth_getUncleByBlockNumberAndIndex * response is always empty
- eth_getUncleCountByBlockHash * response is always zero
- eth_getUncleCountByBlockNumber * response is always zero
- eth_newBlockFilter
- eth_newFilter
- eth_protocolVersion * response is always zero
- eth_sendRawTransaction * can relay TXs to another node
- eth_subscribe
- eth_syncing
- eth_uninstallFilter
- eth_unsubscribe

3）对应net api有：【对应endpoints_net.go内各函数】
- net_version
4）对应txpool api有：【对应endpoints_txpool.go内各函数】
- txpool_content * response is always empty
5）对应web3 api有：【对应endpoints_web3.go内各函数】
- web3_clientVersion
- web3_sha3
6）对应zkevm api有：【对应endpoints_zkevm.go内各函数】
- zkevm_batchNumber
- zkevm_batchNumberByBlockNumber
- zkevm_consolidatedBlockNumber
- zkevm_getBatchByNumber
- zkevm_isBlockConsolidated
- zkevm_isBlockVirtualized
- zkevm_verifiedBatchNumber
- zkevm_virtualBatchNumber
