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.

Bitdeer Technologies, led by Jihan Wu and based in Singapore, has unveiled the very latest development in the world of Bitcoin mining technology with the announcement of the successful testing of its proprietary Bitcoin mining chip, slated for integration into its forthcoming mining rig. In addition, the firm has followed up on March 4 with the publication of financial results for Q4 2023.Photo by Thought Catalog on UnsplashSealminer A1The company revealed on X that its inaugural crypto mining chip, known as the SEAL01, destined to drive the Sealminer A1 mining rig, was engineered utilizing four-nanometer process technology, a feat achieved in collaboration with a semiconductor fabricator. Bitdeer boasts that this chip exhibits a power efficiency ratio of 18.1 J/TH. At the heart of Bitdeer's latest achievement lies the SEAL01 chip, the culmination of years of dedicated research and development. By harnessing state-of-the-art technology and meticulous planning, Bitdeer aims to tackle the pressing challenges confronting Bitcoin miners, including skyrocketing operational costs and environmental implications. The company claims that the efficiency of the SEAL01 chip not only promises a shift towards more sustainable mining practices but also holds the potential to significantly reduce energy consumption, thereby bolstering profitability and return on investment for miners. "This powerful chip offers enhanced Bitcoin mining performance with minimized power consumption, leading to lower operating costs and a reduced environmental footprint for miners," Bitdeer affirmed in the X post. The firm stopped short of disclosing the launch timeline for its upcoming mining rig. On the financial front, Bitdeer disclosed its financial results for Q4 2023, on March 4. The company reported a total of 111,966,634 outstanding ordinary shares as of Dec. 31, 2023, including class A and class V ordinary shares. Additionally, Bitdeer revealed key operational metrics for Q4 2023, including total Bitcoin mined, power usage across its mining data centers, average cost of electricity and miner efficiency. Bitdeer's shares closed up 2.11% at $6.76 on Nasdaq on Friday, indicating a positive market response to its recent newly developed Bitcoin mining chip. However, trading outside regular hours, going into March 4, have seen the share price peak at $7.52, yet having retraced to $6.9 at the time of writing.
