Cardanoscan

A Cardano blockchain explorer with a host of features and blockchain analytics tools. Statistics for the Cardano blockchain, and ADA, are shown on the home page

Users can use Cardanoscan to search different elements of the blockchain say transactions, blocks, epochs, pools, tokens etc, using filters and a single search bar.

A menu bar contains various functions which allow users to deep dive into certain elements of the blockchain, such as the transactions being done through it and the things being built on top of it. For instance users can view:

Only transactions with metadata
Withdrawals from the blockchain
Protocol updates
Top staking accounts and top addresses
Pools and their statistics
Certificates for pool (registration and deregistration), delegations, instantaneous rewards and more

Cardanoscan allows Stake Pool Operators, SPOs, to verify their pool ownership on the site and then send statistics through a telegram bot to a telegram channel where users can subscribe to as many pools as they want and receive these updates from SPOs.

Cardanoscan also offers a testnet explorer which was funded by Project Catalyst

Metadata

Metadata is an element of a Cardano transaction that can be inputed by the user or automatically generated. It is stored on the blockchain with the transaction that it was sent with. This means that, just like the transactions themselves, metadata is immutable, i.e. unchangeable, and stored forever on the Cardano blockchain.

Anyone can add metadata into a transaction and that metadata is then stored on the blockchain. Many wallets allow you to add custom metadata to a transaction.

Metadata can only be made up of characters i.e. numbers, letters and punctuation, and cannot be a file type, i.e. you cannot unload files like PDFs or MP3s to the blockchain. The size of the metadata you can add to a transactions is limited to 16KB, and a character is, typically, 1 Byte, so that means you can add up to 1600 characters as metadata with any transaction.

Metadata can be used for many purposes the most common is to give some form of context to the transaction. Metadata has been used to store supply chain data, to send arbitrary message to be stored on the blockchain, and to store the hash of a document (allowing the blockchain to be used for proof-of-existence). People have used metadata, on the testnet, to immortalize the Cardano whitepaper, by writing it onto the blockchain as transactions across multiple transactions.

Many block explorers allow users to view and search transaction metadata. Remember, anything you add as metadata to a transaction will always be publicly available on the blockchain.

MYTH

Blockchains are a secret way of transacting money and hiding the exchange of funds from others and authorities.

TRUTH

A blockchain is a transparent ledge, meaning that anyone can explore the transactions on it when given the tools. Those tools exist for all blockchains (except the few privacy chains that have been created that do in fact hid the exchange of funds).

Explorers allow anyone to search and explore all the transactions on the blockchain. The blockchain can be searched and explored in numerous ways using: wallet addresses, transaction IDs (TX ID), block numbers, epoch number, slot/epoch number, stake pool ticker, token ticker, staking keys. Users can also search for individual assets and transaction metadata if they have the information. Developers can use APIs to scrape data from the blockchain to inform all sorts of processes, programs, and to create data sets.
