Block Explorer

Explore Real-Time and Historical Snapshots of Your Blockchain

When building blockchain networks and applications you need to be able to explore the chain. With Kaleido's block explorer you can easily gain insights by exploring block data in real-time.
What it is

What It Is

A dashboard that provides real-time and historical snapshots of your blockchain.

Gain new insights with real-time visibility into the transaction history and operations of your blockchain network. Visualize your ledger, smart contracts and transactions, with a dashboard backed by a time series database and robust APIs.

Fully Transparent Dashboard

Block Explorer allows you to view on-chain activities by easily browsing blocks, transactions, smart contracts, gas rates, gas consumption and more in your environment.

Customized Data Views

Leverage the intuitive ledger API to create customized views of data on the chain. Drill down into block detail and extract patterns from relevant subsets of information.

Source Code Verification

Integrated source code verification feature to turn indecipherable byte code of a smart contract into plain text that can be verified by a counterparty prior to the issuance of a transaction or query.

How it works

How it Works

The Kaleido Block Explorer is an environment-specific console that provides realtime and historical snapshots of the blockchain.

It can be leveraged for both high-level analytics (e.g. chain height, commonly called contracts, transaction rate, etc.) and more granular insights (e.g. block contents, transaction hashes, sending accounts, etc.).

Search Bar

Use the search bar to jump directly to a specific subset of the ledger. The search bar accepts three valid inputs:

  • Block Number: The number of the desired block for inspection. For example, enter 0 to see the contents of the chain’s genesis block. Bear in mind that the Kaleido consensus mechanisms may cut blocks regardless of transaction presence (PoA and IBFT output multiple blocks in a minute). As a result, if you are operating in an environment with low transaction throughput and running PoA or IBFT consensus, a large allotment of blocks will be devoid of transactions.
  • Contract Address: callable address of an Ethereum smart contract deployed within the environment.
  • Transaction Hash: The ID of a specific transaction. A transaction implies that byte code has been executed by the EVM. These include deployments of smart contracts and subsequent invocations.


By default, the Block Explorer home screen displays the 25 most recent blocks on the chain. As mentioned above, blocks are minted in accordance with the consensus protocol’s system configuration and do not necessarily contain transactions. Click the block number to see the contents of a specific block. 


Transactions are listed chronologically with the most recent transaction at the top of the list. The transaction table exposes truncated values for transaction hash and the sending account. Additionally, if the transaction is a smart contract deployment, it is denoted with a 'New Contract Created' tag.
