Ethereum's full nodes become more and more expensive to maintain, and even fast synchronization can take a long time. Many contract developers deploy contracts only through Infura, but it has a limited number of times and requires registration, which is cumbersome. In Ethereum 2.0, each beacon chain node needs to connect 1.0 nodes. If it is too complicated for the verifier to build the node by yourself, it needs to build 1.0 nodes, beacon chain nodes and verify the human node. I want to get a batch of RPC nodes through P2P network. The availability of RPC node data can be verified by light les protocol, which can save some costs。
use ethereum devp2p node discovery v4, if peers < 8, local node will find nodes. when i get many enode, i will use rpc.dial(ip+port) try connect. if connect ,i will store it. according chainid and networkid find useful nodes，use les protocol getbalance or other method verify rpc nodes result.
For prerequisites and detailed build instructions please read the Installation Instructions on the wiki.
Building geth requires both a Go (version 1.13 or later) and a C compiler. You can install
them using your favourite package manager. Once the dependencies are installed, run
make gethor, to build the full suite of utilities:
make all
./build/bin/geth --networkid 1
