This module allows you to get information about the node and blockchain. It can be accessed from the global variable node
.
node.getBlock(height)
Get a tendermint block at the given height.
height
- String|Number
: The target block height
​Tendermint Block​
node.getBlock(101)
node.getHeight()
Get the current height of the blockchain.
String
- The height of the node.
node.getHeight()
"123"
node.getBlockInfo(height)
Get a summary block at the given height. This block information is indexed by MakeOS (not Tendermint).
height
- String|Number
: The target block height
String
- The height of the node.
node.getBlockInfo(101)

node.getValidators(height)
Get a list of validators that processed a given block.
height
- String|Number
: The target block height whose validators will be returned.
Object
- The result object
node.getValidators(101)
