The Ethereum mainnet has officially completed The Merge—a historic transition from a proof-of-work (PoW) consensus mechanism to a proof-of-stake (PoS) model. This pivotal moment marks the end of energy-intensive mining and the beginning of a more sustainable, scalable blockchain future. As the world watched this technological evolution unfold, institutions, developers, and crypto enthusiasts embedded symbolic messages into Ethereum’s blockchain, creating digital time capsules that will last forever.
These on-chain inscriptions are more than just text—they represent a collective acknowledgment of progress, innovation, and the community’s shared vision for decentralized technology.
The First NFT Series Minted After The Merge
Shortly after Ethereum produced its first PoS block at height 15,537,394, a user made history by minting what is believed to be the first NFT collection after The Merge. According to Etherscan data, the transaction cost a staggering 36.82 ETH (approximately $58,945 at the time), underscoring the symbolic importance of securing this milestone moment on-chain.
The NFT series, titled "The Transition V2", consists of 100 unique digital collectibles. Each piece symbolizes the shift from old-world infrastructure to a greener, more efficient blockchain paradigm. By paying such a high gas fee, the creator ensured their transaction was prioritized and permanently recorded in the inaugural PoS block—one of the most historically significant blocks in Ethereum’s timeline.
This act reflects a growing trend in the Web3 space: using blockchain not only as a ledger for value but as a canvas for cultural expression and historical documentation.

HashKey Capital Sends a Message of Innovation
Embedded within the same landmark block is a message from HashKey Capital, a leading digital asset management firm focused on blockchain innovation:
Supporting the next wave of blockchain innovation!
This simple yet powerful statement captures the sentiment of many institutional players who see The Merge as more than just a technical upgrade—it’s a catalyst for broader adoption, improved security, and new financial infrastructure. As traditional finance increasingly intersects with decentralized systems, messages like these signal long-term confidence in Ethereum’s role as a foundational layer for the future internet.
Such gestures also highlight how institutions are beginning to participate in on-chain culture, not just through investments, but through symbolic engagement that resonates across communities.
The Final Proof-of-Work Block: A Tribute to Mining Legacy
Before PoS took over, Ethereum’s last PoW block—block 15,537,393—was mined by F2Pool, one of the oldest and most respected mining pools in the cryptocurrency industry. Founded in 2013, F2Pool played a crucial role in securing early blockchain networks, including Bitcoin and Ethereum.
In this final mined block, the miner left behind an emotional message:
"七彩神仙魚F!"
This phrase refers to "Discus Fish F!", a nickname for Mao Shihang, co-founder of F2Pool. It's both a personal signature and a tribute to the human side of mining—the countless individuals who contributed computational power and passion to keep the network secure for years.
But F2Pool didn’t stop there.
They also included a famous quote from American philosopher Terence McKenna, which reads:
“You make the commitment and nature will respond to that commitment by removing impossible obstacles. Dream the impossible dream and the world will not grind you under, it will lift you up. This is the trick.”
This powerful message was inscribed via a transaction funded by the VanityBlocks NFT project—an initiative dedicated to immortalizing significant blockchain events as digital art. The team spent 30 ETH to encode McKenna’s words directly into the final PoW block, turning it into a philosophical monument on the blockchain.
The resulting NFT, named "The Last POW Block", is now available for auction on OpenSea, serving as both a collector’s item and a historical artifact representing the end of an era.
Why On-Chain Messages Matter
Embedding text into blockchain transactions may seem like a small gesture, but it carries deep significance:
- Immutability: Once written, these messages can never be altered or deleted.
- Transparency: Anyone can verify them using public explorers like Etherscan.
- Cultural Value: They capture emotions, philosophies, and milestones in real time.
As blockchain evolves beyond finance into areas like digital identity, governance, and art, these on-chain inscriptions become part of our shared digital heritage.
Moreover, they reflect how decentralized networks enable global participation—anyone, anywhere, can leave a mark on history without needing permission.

Frequently Asked Questions (FAQ)
Q: What was the purpose of The Merge?
A: The Merge transitioned Ethereum from energy-heavy proof-of-work mining to energy-efficient proof-of-stake validation. This change reduces Ethereum’s energy consumption by over 99%, making it more environmentally sustainable while maintaining security and decentralization.
Q: Can anyone leave messages on Ethereum blocks?
A: Yes. Users can include text in transaction data fields when sending ETH or interacting with smart contracts. While not all clients display these notes by default, they are permanently stored on the blockchain and viewable through explorers like Etherscan.
Q: Why did someone pay 36.82 ETH to mint an NFT after The Merge?
A: The high gas fee ensured priority processing during a highly congested network period. More importantly, it secured a place in Ethereum’s history—the first NFT minted under PoS—making it a valuable digital collectible.
Q: What happened to Ethereum miners after The Merge?
A: Miners who previously secured the network via PoW can no longer mine ETH. Many have transitioned to other PoW-based chains (like Ethereum Fair or Ravencoin), repurposed hardware, or exited the space entirely.
Q: Is “The Last POW Block” NFT officially endorsed by Ethereum?
A: No. It was created independently by the VanityBlocks team as a commemorative project. However, its location in the final PoW block gives it cultural and historical weight within the community.
A New Chapter Begins
The Merge wasn’t just an upgrade—it was a revolution written in code. From philosophical quotes to bold artistic statements, the messages etched into these transition blocks remind us that technology is shaped by people.
As Ethereum moves forward with plans for sharding, rollups, and further scalability improvements, today’s historic blocks serve as anchors—connecting past efforts with future possibilities.
Whether you're an investor, developer, or observer, now is an exciting time to engage with blockchain’s evolving landscape. The infrastructure is maturing, use cases are expanding, and opportunities abound.
