The Ethereum blockchain continues to serve as a cornerstone of decentralized innovation, processing thousands of transactions daily and supporting a vast ecosystem of decentralized applications (dApps), smart contracts, and digital assets. In this deep dive, we explore Ethereum Block 20,256,138, mined on July 7, 2024, to uncover key performance metrics, transaction dynamics, and miner rewards. Whether you're a developer, investor, or blockchain enthusiast, understanding block-level data provides valuable insights into network health and activity trends.
Overview of Ethereum Block 20,256,138
Mined at 05:30:59 UTC on July 7, 2024, this block represents a snapshot of Ethereum’s real-time transaction processing capability. It contains 245 transactions and 80 internal transactions, with a total value transferred of 13.8994 ETH, equivalent to approximately $41,442.35** at the time of mining. The average transaction value was **0.0567 ETH ($169.15), indicating a mix of small retail transfers and larger institutional movements.
This block was validated by an unknown miner associated with the address 0x95...afe5. While the identity remains anonymous — consistent with Ethereum’s decentralized ethos — the technical details reveal much about how consensus and incentives function in the post-Merge proof-of-stake (PoS) environment.

Key Metrics at a Glance
- Block Number: 20,256,138
- Timestamp: July 7, 2024, 05:30:59 UTC
- Miner Address:
0x9522...bafe5 - Total Transactions: 245
- Internal Transactions: 80
- Total Value Transferred: 13.8994 ETH (~$41,442.35)
- Average Transaction Value: 0.0567 ETH
- Median Transaction Value: 0.0000 ETH (indicating many zero-value or contract calls)
- Gas Used: 19,251,113 (64.17% of the 30,000,000 gas limit)
- Block Size: 77,336 bytes
These figures reflect efficient utilization of block space without congestion, suggesting stable network conditions during this period.
Miner Rewards and Transaction Fees
One of the most critical aspects of any block is the reward structure for validators (formerly miners). In Ethereum’s current PoS model, validators earn income through base issuance and priority fees (tips).
For Block 20,256,138:
- Base Reward: 0.06 ETH (~$178.90)
- Fee Reward: 0.09712 ETH (~$289.58)
- Total Validator Earnings: 0.15712 ETH (~$468.48)
The fee reward came entirely from the 245 transactions included in the block. This indicates strong demand for block inclusion at the time, likely driven by dApp interactions, token swaps, or NFT trades occurring across DeFi platforms.
Notably, the fee reward exceeded the base reward, highlighting a shift toward user-driven validator compensation — a trend increasingly common during periods of elevated network activity.
Technical Deep Dive: Block Headers and Consensus
Understanding the structural components of a block helps assess its integrity and place within the chain.
- Block Hash:
0xb8f...c8955 - Parent Hash:
0x9ee...f3749— links securely to the previous block - State Root:
0x796...880d9— represents the global state after all transactions are executed - Sha3Uncles:
0x1dc...49347— confirms no uncle blocks were referenced - Nonce:
0— irrelevant in PoS; retained for backward compatibility - Total Difficulty:
5.875e+22— historical metric from the proof-of-work era
Although Ethereum no longer uses proof-of-work, these fields remain for compatibility with legacy systems and explorers.
The absence of uncle blocks (Uncles: 0) is typical in PoS, where forks are minimized due to the deterministic nature of slot-based block proposals.
Network Health and Capacity Insights
This block operated at 4.92% capacity relative to total chain depth (depth: 2,589,264), indicating normal progression without reorganization risks. The gas usage rate of 64.17% suggests moderate network load — far below congestion levels that typically trigger high fees.
Additionally:
- Distance since last block: ~11 minutes (within expected parameters for 12-second slot times)
- Value Today (ETH price fluctuation): The transferred ETH is now worth $35,422.65, reflecting market depreciation since mining
This variance underscores the importance of timing in blockchain transactions — both for users and validators assessing realizable returns.

Frequently Asked Questions (FAQ)
What does "unknown miner" mean in Ethereum block data?
Since Ethereum transitioned to proof-of-stake in 2022, the term "miner" is technically outdated. Today’s blocks are proposed by validators, not miners. When an explorer labels a validator as “unknown,” it means the entity hasn’t publicly identified themselves or linked their address to a known staking pool or service.
Why is the median transaction value zero?
A median value of 0.0000 ETH often occurs when many transactions involve smart contract executions rather than direct ETH transfers. These zero-value transactions may trigger functions like voting, minting NFTs, or updating contract logic — common in DeFi and Web3 apps.
How are validator rewards calculated post-Merge?
Validator rewards now consist of:
- Base rewards based on total staked ETH
- Priority fees (tips) paid by users to prioritize transactions
- MEV (Maximal Extractable Value) — optional, not reflected in standard explorer data
In this block, fees surpassed base rewards, showing active user participation.
Is low block capacity a concern?
No. A capacity usage of 4.92% refers to chain depth, not storage limits. More relevant is gas utilization (64.17%), which shows healthy but not overloaded network conditions — ideal for fast confirmations without excessive fees.
Can I track future blocks like this one?
Yes. Blockchain explorers allow real-time monitoring of upcoming and recent blocks. You can watch transaction volume, fee trends, and validator behavior to anticipate network congestion or opportunities in DeFi yield farming.
What happened to Ethereum difficulty?
Difficulty is a legacy metric from proof-of-work. While still displayed for historical continuity, it no longer applies under PoS. The network now uses total effective balance and randomized validator selection instead.
