Blockchain explorers are the front door to onchain activity. They are how users verify transactions, developers debug contracts, and institutions audit token flows. But when the data on the ledger is encrypted, the explorer has to evolve too.

Today, we are announcing that Blockscout, the leading open-source blockchain explorer, now natively supports ERC-7984 confidential tokens. This means that encrypted token activity can be indexed, explored, and queried without compromising the privacy guarantees that confidential tokens are designed to protect.

This isn't just a frontend update. It's a foundational infrastructure milestone: the first block explorer to recognize and surface confidential token activity as a first-class citizen.

Why Explorer Support Matters

Confidential tokens change the rules of what's visible onchain. With ERC-7984, balances and transfer amounts are encrypted using Fully Homomorphic Encryption (FHE). The blockchain processes these values without ever seeing the plaintext. Only authorized parties can decrypt them.

But transactions and transfer events still happen onchain. They still need to be indexed, categorized, and made navigable. Without proper explorer support, confidential tokens would exist in a blind spot, present on the ledger but invisible to the tools everyone relies on to understand onchain activity.

For the Zama ecosystem, this integration solves a critical usability gap. Developers building confidential applications need to inspect contract activity. Users need to confirm that transfers occurred. And institutions evaluating the Zama Protocol need to see that encrypted computation is happening at scale, without needing to decrypt anything.

Blockscout's native support for ERC-7984 delivers exactly this.

What the Integration Includes

Blockscout's integration introduces several key capabilities for confidential tokens.

Token Type Recognition. ERC-7984 is now a dedicated token type within Blockscout, alongside ERC-20, ERC-721, and ERC-1155. Users can filter and identify confidential tokens on the Tokens page, seeing which contracts implement the standard and tracking their activity across the network, even though balances remain encrypted.

Confidential Transfer Tracking. When a confidential token transfer occurs, the transfer event is emitted onchain as usual. Blockscout indexes these events and displays them as confidential transfers, showing the sender, recipient, transaction hash, and block, while marking the transfer amount as confidential. Users can confirm that a transfer happened without the value being revealed.

API Support. Blockscout's APIs now support querying and filtering ERC-7984 token activity. Developers can retrieve confidential transfer histories and analyze encrypted token usage programmatically, enabling integration with dashboards, analytics tools, and compliance workflows.

A Growing Ecosystem of Real Applications

This Blockscout integration arrives at a moment when confidential tokens are rapidly moving from concept to production. Over the past months, the Zama ecosystem has seen a series of real-world milestones that demonstrate the practical demand for encrypted onchain finance:

Bron executed the first confidential payroll on Ethereum mainnet using cUSDT, proving that organizations can settle salaries onchain without exposing compensation data.

GSR completed the first confidential OTC trade on Ethereum, showing that institutional liquidity providers can operate on public chains without broadcasting their strategies.

And Raycash is building a full consumer finance experience on top of confidential stablecoins, combining self-custody, privacy, and compliance in a single product.

The confidentiality layer for blockchain is here, and applications will generate more and more confidential token activity that now surfaces natively in Blockscout.

What Comes Next: FHE Operation Visibility

Confidential tokens are just the first layer. Behind every encrypted transfer, a series of FHE operations are executed by the Zama Protocol's coprocessor network. These operations, the encrypted additions, subtractions, and comparisons that power confidential smart contracts, represent the computational backbone of the entire system.

Blockscout is already preparing support for tracking and visualizing these FHE operations within transactions. Future updates will allow users to inspect encrypted computation activity, including operation types and associated metrics such as Homomorphic Compute Units (HCU). This will provide unprecedented visibility into how confidential contracts execute and how encrypted computation flows across the network.

Privacy and Transparency Were Never Opposites

The blockchain industry spent years treating privacy and transparency as a binary choice. You could have a public ledger that everyone can audit, or a private system that no one can see into. The Zama Protocol was built on the conviction that this is a false tradeoff.

With FHE, computation is verifiable without being visible. Blockscout's integration of ERC-7984 makes this principle tangible: users can explore onchain activity, confirm that transfers occurred, and audit contract behavior, all without a single encrypted value being exposed.

As confidential token standards mature, this model of "private data, public verification" will become the foundation for bringing serious financial infrastructure onchain. Explorer support is a prerequisite for that future, and with Blockscout, it's now live.

Getting Started

Developers building confidential applications on the Zama Protocol can explore their token activity on Blockscout today. Whether you are deploying confidential stablecoins, building private DeFi protocols, or integrating encrypted payments, the tools to inspect and verify your onchain activity are now available.

Privacy is necessary for an open society in the electronic age. Privacy is not secrecy. A private matter is something one doesn't want the whole world to know, but a secret matter is something one doesn't want anybody to know. Privacy is the power to selectively reveal oneself to the world.If two parties have some sort of dealings, then each has a memory of their interaction. Each party can speak about their own memory of this; how could anyone prevent it? One could pass laws against it, but the freedom of speech, even more than privacy, is fundamental to an open society; we seek not to restrict any speech at all. If many parties speak together in the same forum, each can speak to all the others and aggregate together knowledge about individuals and other parties. The power of electronic communications has enabled such group speech, and it will not go away merely because we might want it to.Since we desire privacy, we must ensure that each party to a transaction have knowledge only of that which is directly necessary for that transaction. Since any information can be spoken of, we must ensure that we reveal as little as possible. In most cases personal identity is not salient. When I purchase a magazine at a store and hand cash to the clerk, there is no need to know who I am. When I ask my electronic mail provider to send and receive messages, my provider need not know to whom I am speaking or what I am saying or what others are saying to me; my provider only need know how to get the message there and how much I owe them in fees. When my identity is revealed by the underlying mechanism of the transaction, I have no privacy. I cannot here selectively reveal myself; I must always reveal myself.Therefore, privacy in an open society requires anonymous transaction systems. Until now, cash has been the primary such system. An anonymous transaction system is not a secret transaction system. An anonymous system empowers individuals to reveal their identity when desired and only when desired; this is the essence of privacy.Privacy in an open society also requires cryptography. If I say something, I want it heard only by those for whom I intend it. If the content of my speech is available to the world, I have no privacy. To encrypt is to indicate the desire for privacy, and to encrypt with weak cryptography is to indicate not too much desire for privacy. Furthermore, to reveal one's identity with assurance when the default is anonymity requires the cryptographic signature.We cannot expect governments, corporations, or other large, faceless organizations to grant us privacy out of their beneficence. It is to their advantage to speak of us, and we should expect that they will speak. To try to prevent their speech is to fight against the realities of information. Information does not just want to be free, it longs to be free. Information expands to fill the available storage space. Information is Rumor's younger, stronger cousin; Information is fleeter of foot, has more eyes, knows more, and understands less than Rumor.We must defend our own privacy if we expect to have any. We must come together and create systems which allow anonymous transactions to take place. People have been defending their own privacy for centuries with whispers, darkness, envelopes, closed doors, secret handshakes, and couriers. The technologies of the past did not allow for strong privacy, but electronic technologies do.We the Cypherpunks are dedicated to building anonymous systems. We are defending our privacy with cryptography, with anonymous mail forwarding systems, with digital signatures, and with electronic money.Cypherpunks write code. We know that someone has to write software to defend privacy, and since we can't get privacy unless we all do, we're going to write it. We publish our code so that our fellow Cypherpunks may practice and play with it. Our code is free for all to use, worldwide. We don't much care if you don't approve of the software we write. We know that software can't be destroyed and that a widely dispersed system can't be shut down.Cypherpunks deplore regulations on cryptography, for encryption is fundamentally a private act. The act of encryption, in fact, removes information from the public realm. Even laws against cryptography reach only so far as a nation's border and the arm of its violence. Cryptography will ineluctably spread over the whole globe, and with it the anonymous transactions systems that it makes possible.For privacy to be widespread it must be part of a social contract. People must come and together deploy these systems for the common good. Privacy only extends so far as the cooperation of one's fellows in society. We the Cypherpunks seek your questions and your concerns and hope we may engage you so that we do not deceive ourselves. We will not, however, be moved out of our course because some may disagree with our goals.The Cypherpunks are actively engaged in making the networks safer for privacy. Let us proceed together apace.Onward.Eric Hughes9 March 1993
