Cardano recently released a research paper on its expansion solution, Mithril. Mithril was launched on the Cardano mainnet in July, and the Mithril 2 research paper introduces "innovative cryptographic technology." Romain Pellerin, Chief Technology Officer of Input Output Global (IOG), summarized the key points covered in the Mithril 2 paper. Pellerin explained that the paper introduces a technology called "Approximate Lower Bound Arguments" (ALBA). The goal of ALBA is to allow individuals to prove ownership of large datasets without disclosing the entire record. According to Pellerin, this method is applicable for proving ownership of multiple digital signatures from different individuals without disclosing the details of each signature.

FASB's fair value accounting standard for Bitcoin officially takes effect today
On December 16th, according to The Bitcoin Historian, an editor at Bitcoin Magazine, the fair value accounting standards for Bitcoin by the Financial Accounting Standards Board (FASB) officially took effect. Previously, companies could only measure their held Bitcoin assets by historical cost and could not reflect their market value growth. The new standard allows companies to use fair value measurement methods to more accurately reflect the actual value of their Bitcoin assets, which will reduce accounting barriers for companies to include Bitcoin on their balance sheets. MicroStrategy founder Michael Saylor previously stated that FASB has officially passed fair value accounting rules for Bitcoin, which will apply to fiscal years beginning after December 15, 2024. This improvement will encourage companies to adopt Bitcoin as a reserve asset. -
