Overview of Ethereum Block 15,599,534
Mined at 12:08:35 UTC on September 24, 2022, this block represents a snapshot of Ethereum’s state during a period of active usage. It contains 494 transactions, with a total value transferred of 101.0515 ETH (approximately $133,775** at the time). The average transaction size was **0.2046 ETH ($270.80), indicating a mix of small retail transfers and larger movements.
The miner who successfully added this block to the chain received a total reward of 2.4521 ETH, consisting of:
- Base block reward: 2.00 ETH
- Transaction fees (priority fees): 0.4521 ETH ($598.48)
This structure reflects Ethereum’s pre-Merge consensus mechanism — Proof of Work (PoW) — where miners were compensated for computational effort and included transaction fees as incentives.
Key Block Metrics and Their Significance
Hash & Parent Chain Information
- Block Hash:
0xba1-d260d(truncated for readability) - Parent Hash:
0x9dc-6d38a - Sha3Uncles:
0x1dc-49347
These cryptographic identifiers ensure immutability and traceability. Each block references its parent, forming an unbroken chain. The absence of uncle blocks (Uncles: 0) indicates smooth consensus without orphaned chains.
State Root and Network Integrity
- State Root:
0xbbe-e04e7
The state root is a Merkle root representing the entire state of all accounts and smart contracts after processing all transactions in the block. Any discrepancy would indicate tampering — making it crucial for verifying network integrity.
Nonce and Mining Process
- Nonce:
0
In PoW mining, the nonce is adjusted repeatedly until the resulting hash meets difficulty requirements. A nonce of zero suggests either a rare early success or post-processing simplification in display.
Depth and Confirmation Security
- Depth: 7,245,485 confirmations
This high depth means the block is deeply embedded in the chain, making reversal practically impossible. In blockchain terms, deeper = more secure.
Gas Usage and Network Efficiency
Gas is Ethereum’s unit of computational effort. This block used:
- Gas Used: 29,987,555 (99.96% of limit)
- Gas Limit: 30,000,000
Operating near full capacity indicates strong network demand at the time. High gas utilization can lead to increased fees but also reflects robust activity — such as DeFi interactions, NFT mints, or token swaps.
With nearly full blocks, users may have experienced slightly elevated transaction costs. However, efficient packing of transactions maximizes throughput under constrained block sizes.

Transaction Volume and Economic Impact
This block processed:
- External Transactions: 494
- Internal Transactions: 112 (often associated with smart contract calls)
Total value sent: 101.0515 ETH (~$133,775 at the time). Adjusted for today’s prices (as of 2025), that amount equals approximately **$258,136**, highlighting Ethereum’s long-term value appreciation.
Key statistical insights:
- Average Value per Transaction: 0.2046 ETH
- Median Value: 0.08978 ETH
The significant gap between average and median suggests a skewed distribution — likely due to a few large transfers inflating the mean, while most transactions were smaller in size.
Such patterns are common in blockchain networks where whales (large holders) coexist with everyday users.
Miner Reward Breakdown
The successful miner address: 0x4675c7e5baafbffbca748158becba61ef3b0a263
Received:
- Block Reward: 2.00 ETH ($2,647.66)
- Fee Reward: 0.4521 ETH ($598.48)
- Total Earned: 2.4521 ETH (~$3,246.14)
This fee-to-reward ratio (~18% from fees) shows healthy user participation. Even before EIP-1559 reformed fee mechanics, user-driven demand contributed meaningfully to miner income.
Network Context and Historical Relevance
At the time of mining, Ethereum was still operating under Proof of Work. Just days later, on September 15, 2022, the network underwent The Merge, transitioning to Proof of Stake (PoS). While this block predates that shift by about nine days, it stands among the final PoW blocks ever mined — adding historical significance.
Post-Merge, block rewards are no longer paid to miners but to validators, and fee structures have evolved with base fee burning and priority fee rewards.
Difficulty and Total Difficulty
- Difficulty: Not applicable (PoS transition complete)
- Total Difficulty: 5.875 × 10²²
Total difficulty was a cumulative measure of computational work required to mine all previous blocks — a metric critical for chain validity during PoW. After The Merge, this concept became obsolete.
Frequently Asked Questions (FAQ)
Q: What does "capacity" mean in a blockchain block?
A: Capacity refers to the percentage of the gas limit used in a block. Here, 8.22% likely refers to another metric or is mislabeled; actual gas usage was 99.96% of the limit.
Q: Why is there a difference between average and median transaction values?
A: A few large transactions pull up the average, while the median reflects typical user behavior. This divergence signals wealth concentration or institutional activity within the block.
Q: What happened to Ethereum mining after this block?
A: Ethereum fully transitioned to Proof of Stake with The Merge on September 15, 2022. Mining ceased to exist; validators now secure the network using staked ETH.
Q: How can I verify this block data independently?
A: You can use any Ethereum blockchain explorer like Etherscan or OKX Web3 Explorer to search by block number or hash and view real-time validation.
Q: What are internal transactions?
A: Internal transactions are message calls between smart contracts or contract-to-external-account transfers triggered by external transactions. They don’t consume gas directly but occur as side effects of executed code.
Q: Is this block still relevant today?
A: Yes — especially for historical analysis, forensic auditing, or understanding pre-PoS Ethereum economics. Blocks like these form the foundation of Ethereum’s legacy.
