What is a block explorer?
Blockchain browser is a tool and website used to search and query blockchain information. It provides users with the ability to browse and query information on the blockchain. Due to the public transparency of the blockchain, users need a medium to view what is happening on the chain, and the blockchain browser is this medium. Users only need to enter the hash value, wallet address or contract address of the transaction in the blockchain browser to query their details.

Data
Ethereum is transparent by design and all information can be verified. Block explorers provide an interface for obtaining this information. This applies to Ethereum's mainnet and testnet, if you need this data. The data is divided into execution data and consensus data. Execution data refers to transactions that have been executed within a specific block. Consensus data refers to the blocks themselves and the validators who proposed them.
The following is a summary of the data types you can get from the block explorer.
Execution Data
A new block is added to Ethereum every 12 seconds (unless the block proposer misses the proposal opportunity), so there is a near-steady data flow Added to the block explorer. Blocks contain a lot of important data that you may find useful:
Standard Data
- Block Height – Block number and the length of the blockchain when the current block was created (in blocks)
- Timestamp - The time when the block was proposed
- Transactions - The number of transactions included in the block
- Transaction fee recipient - From the transaction Address to get gas tips
- Block Reward - The amount of Ether awarded to the validator who proposed the block
- Size - The size of the data within the block (in bytes)
- Gas Consumed – The total number of gas units consumed by transactions in the block
- Fuel Limit – The total gas limit set by transactions in the block
- Fuel Base Fee – Required Minimum multiple required for a transaction to be included in a block
- Burn fee - the amount of ether burned within a block
- Other data – any additional data added to the block by miners
Advanced Data
- Hash - represents the cryptographic hash of the block header (the unique identifier of the block)
- Parent Hash - the current block's Hash of previous block
- State Root – The root hash of the Merkle prefix tree that stores the state of the entire system.
Fuel
The block explorer will not only provide you with data about gas usage in transactions and blocks, but also provide you with information about the current gas price of the network . This will help you understand network usage, submit secure transactions and avoid fuel overspending. Look for APIs that can help you get this information into your own product interface. Fuel specific data covers:
- Estimated number of gas units required for safe but slow transactions (along with estimated price and duration)
- Estimated number of gas units required for general transactions (along with estimated price and duration) )
- Estimated number of gas units required for fast trading (along with estimated price and duration)
- Average confirmation time based on gas price
- Contracts that are consuming gas – In other words, popular products that are being heavily used on the network
- accounts that are consuming fuel – in other words, users who frequently use the network
Transactions
area Block explorers have become a popular place for people to track the progress of their transactions, because the level of detail you can get provides additional certainty. Transaction data contains:
Standard data
- Transaction Hash – The hash generated when the transaction is submitted
- Status – Indicates whether the transaction is pending, failed, or successful
- Block – The block containing this transaction
- Timestamp – The time the transaction was mined by the miner
- Sender – The address of the account that submitted the transaction
- Receiver – The address of the recipient or smart contract that interacted with the transaction
- Tokens Transferred – The list of tokens that were transferred as part of the transaction
- Value – The total value of Ether that was transferred
- Transaction Fee – Amount paid to miners for processing transactions (calculated based on gas price * gas used)
Advanced Data
- Fuel Limit – This The maximum number of fuel units that can be consumed by the transaction
- Fuel consumed – The actual number of fuel units consumed by the transaction
- Fuel price – The price set per fuel unit
- Random number –
fromThe transaction number of the address (remember, it starts at 0, so the nonce 100 is actually the 101st transaction submitted by this account
- Input data – Any additional information required for trading
Account
You have access to a lot of data about your account. This is why it is recommended to use multiple accounts so that your assets and value transfers are cannot be easily traced. There are also solutions being developed to make transactions and account activity more private. Here is the data available for the account:
User Account
- Account Address - A public address that you can use to send funds
- Ethereum Balance - The amount of Ethereum associated with the account
- Total Ethereum Value - The value of Ethereum
- Tokens - The tokens associated with the account and their values
- Transaction History - A list of all transactions for which this account was the sender or recipient
Smart Contracts
The smart contract account has all the data that the user account will have, but some block explorers will even show some code information. For example:
- Contract Creator - Deploy the contract to the master Network address
- Create transaction - includes transactions deployed to the mainnet
- Source code - solidity or vyper code of the smart contract
- Contract ABI - application binary interface of the contract — Calls issued by the contract and data received
- Contract creation code - Compiled bytecode of the smart contract — Create
- contract events when you compile a smart contract written in Solidity or Vyper, etc. - History of methods called in smart contracts — basically a way to see how a contract is used and how often
Tokens
Tokens are a type of contract, so they Will have similar data to smart contracts. But because they have value and can be traded, they have additional data points:
- Type - follows ERC-20, ERC-721 or other token standards
- Price - if If it is an ERC-20 token, it will have a current market value
- Market Cap - If it is an ERC-20, it will have a market cap (calculated based on price * total supply)
- Total Supply - Number of tokens in circulation
- Holders - Number of addresses holding tokens
- Transfers - Number of times tokens have been transferred between accounts
- Transaction history - Included History of all transactions including the token
- Contract Address - The address of the token deployed to the mainnet
- Decimal - ERC-20 tokens are divisible and have decimal places
NETWORK
Some block data looks at the health of Ethereum more comprehensively.
- Total transaction volume - the number of transactions since the creation of Ethereum
- Transactions per second - the number of transactions that can be processed per second
- Ethereum price - 1 The current market price of Ethereum
- Total Ethereum supply - the number of Ethereum coins in circulation — remember that new Ethereum is created in the form of block rewards with each block Created
- Market Cap - Calculation of Price*Supply
Consensus Layer Data
Period
For security reasons, on each A randomized validator committee is created at the end of the period (every 6.4 minutes). Period data includes:
- Period number
- Final status - whether the period has been completed (yes/no)
- Time - the time when the period ended
- Authentication - the certification in the period Amount (votes against blocks within the slot)
- Deposits - Amount of Ether deposits included in the slot (validators must stake Ether to become a validator)
- Slash - against blocks Penalty amount for proposer or prover
- Voting Participation - Amount of staked ether used to prove a block
- Validators - Number of validators active during the period
- Avg. Validator Balance - The average balance of active validators
- Slots - The number of slots contained in a period (a slot contains a valid block)
Slots
A time slot is an opportunity to create a block. The available data for each time slot includes:
- Period - the period during which the time slot is valid
- Slot number

Block
Proof of Stake divides time into slots and periods. This means new data!
- Proposer - The validator selected by the algorithm to propose a new block.
- Period - The period during which blocks are proposed.
- Slot - The time slot for proposed blocks.
- Certification - The number of certifications included in the slot - Certification is the same as voting and indicates that the block is ready to enter the beacon chain

- Proposed Block - Block proposed by the validator
- Certification - Certification provided by the validator
- Deposit - Sender address, transaction hash, block number of the validator's pledged deposit , timestamp, amount and status
Authentication
Authentication is like voting “yes” to adding a block to the chain. Their data is related to the certification record and the verifier who made the certification.
