subnode

subnode

aggregated proxy for sub-archive-nodes of tendermint/cosmos chains

Archive node data is big, major chains could grow 5TB/year and will stop working at some point.

This project is to make archive node could scale forever by breaking data into multiple smaller nodes (called sub-node). Each subnode stores data of 5 millions blocks or 5 TB. Old subnodes are read-only.

As data is spreaded over multiple sub-nodes, its required to have a proxy which aggreates data from sub-nodes and provides compatible rpc/api.

Supported Protocols

• Tendermint RPC/JSONRPC on port 26657
• Tendermint Websocket
• LCD/API on port 1337
• GRPC on port 9090
• Eth JsonRpc on port 8545
• Eth JsonRpc Websocket on port 8546

Usage

install:

make install

start:

subnode start --conf=/path/to/config/file

Configuration

See sample config test.config.evmos.yaml.

blocks config example:

• [1, 100] => from block 1 to block 100 (subnode). In case its last subnode, set to-block to 0 to indicate newest block [101, 0]
• [10] => last 10 recent blocks (for pruned node)
• [] => for archive node

Node on the top of the list has higher priority when selecting.
