Korea unveils detailed plan for retail CBDC transaction pilot with 100K participants

With the general election just over a month away, South Korea’s ruling People Power Party (PPP) has retracted its campaign pledges to allow trading of spot bitcoin ETFs, local media outlet Chosun Biz reported. The PPP has previously drawn substantial attention from the crypto industry, as the party showed its intention to ease a range of crypto regulations in hopes of gaining more votes in the general election.  A political insider familiar with the issue said yesterday that the PPP has recently removed crypto-related agendas from its priority list. The crypto pledges, initially planned to be announced last week, have been permanently suspended, the person said. “The leaders of the PPP are currently focusing on nomination for local constituencies and its satellite People’s Future Party, rather than coming up with additional crypto agendas. As the PPP appears to be embarking on the election campaign starting in March, the likelihood of the ruling party releasing crypto pledges is very slim,” another political circle insider mentioned.Photo by Traxer on UnsplashTalks between PPP and FSC go in vainThe PPP’s decision to retract crypto-related pledges comes after its attempt to approve the introduction and trading of spot bitcoin ETFs met with opposition from the Financial Services Commission (FSC).  Unlike the PPP or its opposition Democratic Party of Korea (DPK) that scrambled to ease crypto regulations ahead of the general election, the FSC’s stance on viewing crypto assets as risky hasn’t changed much. Despite last month’s approval of spot bitcoin ETFs by the U.S. Securities and Exchange Commission (SEC), the FSC continues to ban the issuance of crypto-based financial products or investments in them, stating that crypto assets are not defined as underlying assets under the current Capital Markets Act. This has gotten in the way of the PPP’s plan to delay taxation on crypto gains for as long as two years and allow institutional investments in virtual assets.  The PPP also had to verify all the party members to see if any of them had a record of wrongdoings related to crypto transactions, which further delayed the pledges. This shows politicians’ heightened awareness of crypto-related issues. Last year, the DPK lawmaker Kim Nam-guk made headlines for a scandal, as he was accused of failing to report a considerable amount of crypto assets transactions to the financial authority. PPP lags a step behind its opposition DPKThe DPK has also strived to come up with crypto pledges alongside the PPP. The crypto-related pledges released by the DPK so far largely overlap with those of the PPP, meaning there’s no particular merit to the PPP’s campaign vows leading up to the general election. Many see this as another reason for the PPP’s decision to withdraw crypto pledges. The DPK unveiled its plan on Feb. 21 to legalize spot bitcoin ETFs, and pledged to deduct taxes on crypto gains worth less than KRW 50 million ($37,400). Under the current law, only crypto gains that are worth less than KRW 2.5 million qualify for the tax deduction. Most of these pledges largely align with those of the PPP.  With the PPP’s withdrawal of its plan to ease crypto regulations, the excitement among crypto industry insiders for the upcoming general election appears to have subsided. “Despite the DPK’s promise to allow spot bitcoin ETFs, it is unlikely that we’ll see crypto assets being incorporated into the conventional financial system without the ruling party’s approval, let alone fostering the blockchain industry,” said one crypto insider. 

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.

Korea’s prominent crypto exchanges Bithumb and Korbit have recently resumed charging trading fees, local media outlet Edaily reported. However, these changes in fee policies are reinforcing Upbit’s dominant market position while downsizing Bithumb’s and Korbit’s market shares. Meanwhile, the local banks affiliated with crypto exchanges are benefitting from an uptick in fee revenue from the recent bitcoin boom. According to crypto data intelligence platform CoinGecko on Feb. 28, Upbit accounted for 77.4% of the local market share in crypto transactions, followed by Bithumb (20.43%), Coinone (1.73%), Korbit (0.35%) and Gopax (0.09%). Photo by Markus Winkler on UnsplashShifts in market sharesAs of March 2, the market shares of Bithumb and Korbit decreased by 8.59 percentage points and 0.21 percentage points, respectively. Conversely, Upbit’s dominance grew to 86.57%, up by over 9 percentage points. A Korbit official said it’s too early to pass judgment on Korbit’s market performance, as the exchange’s policies on trading fees could change depending on the market sentiment. The person added that CoinGecko tracks only eight types of tokens traded on Korbit and does not cover all the transactions on the exchange.  Bithumb had previously benefited from charging no fees, driving up its market share to as high as over 40% in December. Following the decision to impose a fee of 0.04% on Feb. 6, however, the exchange has been experiencing a drop in transaction volume. Korbit also reinstated trading fees last Thursday, roughly four months after eliminating them on Oct. 10 as a promotional move. However, it's worth mentioning that the newly introduced trading fee is 0.07%, which is lower than the earlier rate of 0.2%. Meanwhile, Gopax currently exempts fees for users who trade BTC, ETH, XRP and USDC.  No local regulations on fees for crypto transactions At the moment, there are no local regulations on fees for crypto transactions, leaving the task of setting such fees to individual trading platforms. It is known that crypto exchanges in other countries, such as the U.S., set their own rates as well.
