Types of Blockchain Data Available
Ethereum's transparent nature allows verification of all on-chain activities. Block explorers organize this data into two primary categories:
1. Execution Layer Data
This includes transaction-specific information found in each block:
Standard Block Data
- Block height/number
- Timestamp of block proposal
- Transaction count
- Fee recipient address
- Block reward amount
- Gas usage metrics
Advanced Technical Details
- Block hash (unique cryptographic identifier)
- Parent block hash
- StateRoot (Merkle tree root hash)
2. Gas Metrics
Block explorers provide crucial gas-related insights:
- Current network gas prices
- Estimated transaction costs
- Average confirmation times
- High-gas-consuming contracts
- Frequent network users
Transaction Data Breakdown
Track transactions with these detailed metrics:
Essential Fields
- Transaction hash
- Status (pending/failed/success)
- Block inclusion details
- Timestamp
- Sender/receiver addresses
Technical Specifications
- Gas limit and usage
- Gas price paid

Frequently Asked Questions
What's the difference between execution and consensus layer data?
Execution data refers to transaction details within blocks, while consensus data relates to block validation and validator activities.
How often are new blocks added to Ethereum?
Approximately every 12 seconds under normal network conditions.
Can I track pending transactions?
Yes, most block explorers show pending transactions before they're included in blocks.
Are block explorers free to use?
Most offer free basic services, with some providing premium API access.
How do I verify smart contract code?
Upload the source code to match it with the deployed bytecode shown in block explorers.
