Alternatives and detailed information of ckb-indexer

Introduce

All the indexing RPCs built in the CKB has been deprecated since v0.36.0 and removed in v0.40.0. This is a standalone service for creating cell and transaction indexes as an alternate solution.

Usage

Build binary from source

cargo build --release

Connect to default ckb rpc service at http://127.0.0.1:8114 and stores the indexer data at /tmp/ckb-indexer-test folder

RUST_LOG=info ./target/release/ckb-indexer -s /tmp/ckb-indexer-test

Or connect to ckb rpc service at tcp://127.0.0.1:18114

RUST_LOG=info ./target/release/ckb-indexer -s /tmp/ckb-indexer-test -c tcp://127.0.0.1:18114

Indexing the pending txs in the ckb tx-pool

RUST_LOG=info ./target/release/ckb-indexer -s /tmp/ckb-indexer-test -c tcp://127.0.0.1:18114 --index-tx-pool

Run ckb-indexer --help for more information

RPC

`get_tip`

Returns the indexed tip block

Parameters

null

Returns

block_hash - indexed tip block hash
block_number - indexed tip block number

Examples

get indexed tip block hash and number

    "jsonrpc": "2.0",
    "method": "get_tip"
}' \
| curl -H 'content-type: application/json' -d @- \

}

`get_cells`

Returns the live cells collection by the lock or type script.

Parameters

search_key:
    script - Script, supports prefix search
    scrip_type - enum, lock | type
    filter - filter cells by following conditions, all conditions are optional
        script: if search script type is lock, filter cells by type script prefix, and vice versa

        block_range: [u64; 2], filter cells by block number range, [inclusive, exclusive]
    with_data - bool, optional default is `true`, if with_data is set to false, the field of returning cell.output_data is null in the result
order: enum, asc | desc
limit: result size limit
after_cursor: pagination parameter, optional

Returns

objects:
    cells - live cells collection
        output: the fields of an output cell
        output_data: the cell data
        out_point: reference to a cell via transaction hash and output index
        block_number: the number of the transaction committed in the block
        tx_index: the position index of the transaction committed in the block
last_cursor: pagination parameter

`get_transactions`

Returns the transactions collection by the lock or type script.

Parameters

    script - Script, supports prefix search when group_by_transaction is false
    scrip_type - enum, lock | type
    filter - filter cells by following conditions, all conditions are optional
        script: if search script type is lock, filter cells by type script, and vice versa
        block_range: [u64; 2], filter cells by block number range, [inclusive, exclusive]
    group_by_transaction - bool, optional default is `false`, if group_by_transaction is set to true, the returning objects will be grouped by the tx hash
order: enum, asc | desc
limit: result size limit
after_cursor: pagination parameter, optional

Returns

objects - enum, ungrouped TxWithCell | grouped TxWithCells
    TxWithCell:
        tx_hash: transaction hash,
        block_number: the number of the transaction committed in the block
        tx_index: the position index of the transaction committed in the block
        io_type: enum, input | output
        io_index: the position index of the cell in the transaction inputs or outputs

    TxWithCells:
        tx_hash: transaction hash,
        block_number: the number of the transaction committed in the block
        tx_index: the position index of the transaction committed in the block
        cells: Array [[io_type, io_index]]

last_cursor - pagination parameter
