What is Attestation?

When a company or financial institution deposits valuable assets such as dollars or securities overseas and issues on-chain tokens or stablecoins based on those deposits, the most important question is this: "How can we trust that the deposited assets actually exist and are securely stored?" The answer to this fundamental question and the key infrastructure that supports trust in the Web3 era is Asset Attestation.



What is Attestation?


Asset Attestation refers to the process by which an independent third party (such as an accounting firm or law office) officially verifies that the assets deposited offshore (foreign institutions) actually exist. In other words, it is like having external experts personally come to confirm whether your valuable digital assets are safely stored in a vault.


This verification process is an essential step to transparently prove to all market participants (users, regulators, partners) that the real assets (dollars, deposits, securities, physical goods, etc.) that underpin on-chain asset issuance have "a reliable physical basis." It goes beyond simply claiming that the assets 'exist' to objectively demonstrating that they 'truly exist.'



Why should we focus on Attestation now?


Attestation has become a crucial pillar for the sustainability and growth of the Web3 ecosystem, going beyond just a single process. Its importance is as follows.



1. Core of a Regulation-Friendly Structure: Enhancing Legal Trust


Currently, financial authorities and regulators worldwide attach great importance to whether virtual assets are backed by real value on a 1:1 basis and whether this is verified through independent audits. Especially for digital assets that link their value to physical assets, such as stablecoins, the transparency of the issuer's reserves is key to regulatory compliance. Publishing Attestation certificates meets these regulatory requirements and brings about a significant enhancement of legal and institutional trust. This not only reduces the burden on companies but also contributes to the overall health of the digital asset market.



2. Securing Transparency: Eliminating Uncertainty


The digital asset market still carries risks due to its opacity. Doubts about the authenticity of the collateral assets claimed by the issuer can lead to market anxiety at any time. Attestation serves as a powerful tool to alleviate this uncertainty. Users, token holders, and institutions can individually verify the existence of the deposited assets through independent external audit reports. This transparency reduces the market risks arising from opaqueness or fraud and provides investors with greater confidence. Ultimately, it enables healthy growth based on market trust.



3. Building a Trustless Infrastructure: Creating Systemic Trust


One of the core philosophies of Web3 is 'decentralized trust.' Rather than blindly trusting a specific central authority or operator, it aims to build systemic trust based on objective and independent proof materials (blockchain records, audit reports, etc.). Attestation plays a vital role in realizing this philosophy. An independent third party verifies the assets, transparently discloses the results, and even records them on the blockchain, creating an environment of 'systemic trust that does not require belief.' This closely aligns with the core principles of Web3, including decentralization, openness, and automated trust.



How does Attestation actually work?


The Attestation process generally proceeds in the following flow.


  1. Asset Deposit: First, the operator intending to issue on-chain assets (e.g., stablecoins) deposits physical assets (deposits, securities, cash, or even specific physical goods) with designated overseas financial institutions (global banks, specialist custodian firms, etc.).

  2. Due Diligence by Independent Institution: Next, an independent third party, such as an accounting firm or a trusted audit institution, regularly (e.g., once a month, once a quarter, etc.) investigates and verifies the existence, quantity, and legal ownership of the deposited assets. This process involves cross-checking the financial institution's records with the actual assets, and if necessary, conducting physical due diligence.

  3. Issuance of Attestation Report: Once the due diligence is complete, the independent institution transparently records the verification details and issues an official signed Attestation Report. This report is not just a document but can also be linked to the blockchain in the form of an NFT (Non-Fungible Token), and it is made publicly accessible for anyone to review, maximizing the transparency and accessibility of information in Web3.

  4. Issuance/Linking of On-Chain Assets: Finally, the results of the audit report are connected with smart contracts and oracles (services that connect external data to the blockchain such as Net APIs). This ensures that on-chain assets (tokens/stablecoins, etc.) are issued only to the extent that physical collateral is secured, or the validity of already issued on-chain assets is verified in real-time. If physical collateral is insufficient, the on-chain issuance may automatically be restricted.



Web3 Leads the Innovation of Attestation: Differences from Traditional Finance


In the traditional finance (Web2) environment, the exchange of information between audit institutions and asset managers was mainly done through complex manual reporting processes. However, in the Web3 and blockchain environment, Attestation introduces the following innovative changes.


  • On-demand/Real-time Attestation: Through 'oracles,' verification results are automatically provided to smart contracts. This allows for much faster and more efficient real-time verification than traditional monthly or quarterly audits.

  • Immutable Blockchain Records: Verification results are permanently recorded on the blockchain, meaning they cannot be manipulated or changed, maximizing the reliability and transparency of information.

  • Automated Rule Enforcement: On-chain, rules such as "tokens/assets can only be issued to the extent of verified deposited assets" are automatically enforced by smart contracts. This completely eliminates the risk of errors or fraud arising from manual intervention.

  • Compliance with Global Standards: By adopting verification procedures that comply with global standards such as Proof-of-Reserve, international trust can be established.


Such trustless, automated transparent verification structures become essential prerequisites for regulatory compliance, large-scale international transactions, and reliable digital asset management. It can be likened to constantly checking in real-time whether clean blood flows through the veins of the financial system.



Web2 vs Web3 Asset Verification: A Comparative Overview


To clearly understand the importance of Attestation, let's compare the asset verification processes in traditional finance (Web2) and blockchain (Web3) environments.

In Conclusion: Attestation Illuminates the Future of Digital Assets


Attestation is not just an 'external audit' or checklist; it is key infrastructure that guarantees 'true value,' trust, and legal stability in the era of digital asset innovation and regulatory coexistence. This is an essential step for digital assets to deeply integrate into the real economic system beyond mere technological innovation.


In the future, the importance of Attestation infrastructure in the Web3 and blockchain finance sectors will only grow. To build a reliable and transparent on-chain ecosystem, it is more crucial than ever for both companies and users to understand the principles and necessities of the Attestation process.
