Terraform Labs Co-Founder Daniel Shin Denies Wrongdoing in LUNA CollapseShin Hyun-seong, popularly known as Daniel Shin, has refuted accusations against him related to the $40 billion collapse of the stablecoin TerraUSD and its companion token, LUNA, according to a report by local news outlet Newspim. He presented this defense during his initial trial at the Seoul Southern District Court on October 30 (local time).Shin co-founded Terraform Labs, the company responsible for issuing TerraUSD and LUNA. His co-founder, Do Kwon, is currently serving a four-month prison sentence in Montenegro for passport forgery.Photo by Tingey Injury Law Firm on UnsplashProsecution’s allegationsKorean prosecutors allege that since 2018, Shin and his colleagues have concealed the fabricated nature of the “Terra project.” By manipulating trades and releasing misleading information, they purportedly misled investors into thinking the project was successful. It’s believed they sold off their tokens before the LUNA crash in May 2022, earning KRW 462.9 billion ($343.3 million) from these activities. They are suspected of personally taking KRW 376.9 billion from this amount.Prosecutors are focusing on Shin as the potential orchestrator of the LUNA crash. They speculate he began selling LUNA tokens around when Terraform Labs launched the Anchor Protocol in March 2021. This DeFi protocol increased the popularity and value of LUNA tokens. Before the crash, Shin is alleged to have gained at least KRW 154.1 billion.Defense argumentHowever, Shin’s legal team countered by asserting that Shin had cut ties with Kwon in 2020. They argued the decline of TerraUSD and LUNA was due to Kwon’s mishandling of the Anchor Protocol and an external attack, neither associated with Shin. Regarding the exploit, Terraform Labs has pursued legal action in the United States Southern District of Florida, claiming that American market maker Citadel Securities played a part in undermining TerraUSD in May 2022.Defending Shin, his lawyers emphasized that at the inception of the Terra project, there were no legal guidelines specifically for cryptocurrency transactions. Additionally, unlike Do Kwon who kept fleeing abroad, Shin willingly came back to Korea and has been cooperating with the investigation. They also noted he received only 32% of the 70 million LUNA tokens initially promised. Regarding classification, they stated LUNA isn’t legally recognized as a security.Shin’s lawyers further argued the prosecution hasn’t clearly identified victims or adequately outlined the components of fraud in this case. They said the prosecution’s case hinges on viewing LUNA as a security. However, Shin’s legal representatives maintained that under the Korean Capital Markets Act, LUNA isn’t a security, making its trades non-fraudulent.To counter a US court ruling the prosecution presented — that a token is a security — Shin’s defense highlighted that the verdict is from a lower court and remains contested. Earlier, prosecutors had cited a ruling from the United States Southern District Court of New York, which classified the XRP tokens sold to institutional investors as securities.

Bank of Japan Publishes Results of CBDC PoCThe Bank of Japan (BoJ) recently concluded the second phase of its central bank digital currency (CBDC) proof of concept (PoC) project, which began in April. The results of this phase were published on Monday, and they shed light on key aspects such as the comparison between account-based and token-based CBDCs and the management of holding limits for users with multiple accounts.Photo by Manuel Cosentino on UnsplashToken-based CBDCsThe experiments conducted by the central bank covered a wide range of topics. Among the most intriguing findings were the advantages and disadvantages of token-based CBDCs and how to effectively impose holding limits for users with multiple CBDC balances.Token-based CBDCs have garnered interest from various central banks, with some adopting the UTXO token model used by Bitcoin without the use of a distributed ledger. A UTXO or unspent transaction output, defines where a blockchain transaction starts and finishes. The Bank of Japan explored this model and analyzed its pros and cons.In the initial proof of concept, both account-based and token-based CBDCs were examined, considering scenarios where the central bank managed the ledger or shared it with intermediaries like banks. In the token-based model, fixed token denominations were used, similar to physical cash in countries like India, and a centralized ledger was employed. However, in the recent phase, the central bank utilized flexible value tokens similar to UTXO and shared ledger functions with intermediaries.The Bank of Japan favored the flexible value token model due to its ability to handle multiple requests simultaneously. However, it acknowledged that this model may require more technical resources compared to the account-based approach. Challenges may arise when implementing additional functions, such as holding limits, while maintaining optimal performance. The European Central Bank (ECB) also noted in a recent report that most payment providers are accustomed to account-based payments and would incur costs to adapt to token-based systems.Another significant aspect explored by the BoJ was how to impose holding limits when users have multiple CBDC balances through different intermediaries. The challenge lies in determining if the overall holding limit has been breached without compromising user privacy.Homomorphic encryptionOne possible solution discussed in the report is the use of homomorphic encryption, which enables computations to be performed on encrypted data without it first needing to be decrypted. That allows for the necessary checks without intermediaries accessing the specific data being checked. Although this solution may slightly increase processing time, it could introduce a higher risk of data inconsistencies.Alternatively, a simpler approach proposed by the central bank is to establish a per-account holding limit and a limit on the number of accounts a single user can hold, rather than imposing global limits. Ideally, users with multiple accounts would have a higher per-account holding limit compared to those with fewer accounts.Phase 3 underwayWith the next pilot phase already underway, the BoJ aims to test the end-to-end process flow and identify challenges related to integrating with external systems. Additionally, they are creating a CBDC Forum to gather input from the private sector, ensuring a collaborative approach to CBDC development.While investigation and research into CBDCs continues, the BoJ has said that it will make a final decision on CBDC implementation by 2026.
