first_img Lighter average block proof time decreased from 5.3 minutes to about 1 minute

The decentralized perpetual contract protocol Lighter announced that its average block proof time has decreased from about 5.3 minutes to about 1 minute over the past month. This progress was achieved through two independent optimizations launched on July 23 and August 23. Lighter can now complete block verification faster, thereby increasing processing capacity, reducing infrastructure costs, and creating space for further expansion.The first optimization is the Heavy/Light decomposition. This solution splits the transaction circuit into light circuits and heavy circuits, allowing simple quote updates, which account for the vast majority of transactions, to only pay for light constraints, thus halving the proof time. The second optimization comes from the Prover backend optimization brought about by the proof competition held in collaboration with Eigen Labs, which again halves the proof time under the same circuit conditions. The first batch of optimizations went live on August 23, with more batches still in progress. Additionally, on August 10, all Schnorr signature verifications were incorporated into a single Plonky3 proof for each block, resulting in approximately a 20% improvement.The above optimizations are orthogonal and their effects are cumulative. The remaining competition optimizations are expected to bring about an additional 2x improvement, potentially reaching a total of about 10x compared to mid-July. Currently, Lighter's sustained processing capacity has exceeded historical peak loads, and the finality limit for withdrawals has been reduced from about 21-22 minutes to about 16-17 minutes, maintaining stability during peak traffic periods.

first_img Term Finance permanently closes Meta Vaults after governance attack, resulting in a loss of approximately 8.5 million USD

The development team of Term Finance, Term Labs, announced that after the governance attack incident, all Term Meta Vaults have been permanently closed, DAO governance rights have been revoked, but the withdrawal channel remains open. In an update on August 23, Term stated that this closure is irreversible and permanently prevents subsequent deposits, but did not disclose the scale of the remaining assets in the vault, only indicating that it will "explore pathways" to address any gaps, and the amount that depositors can recover remains undecided.Blockchain security company PeckShield estimates that the attacker stole approximately 2,843 ETH (worth about $6.87 million at the time) and 1.68 million USDC (which was later exchanged for about 1.68 million DAI), with total losses estimated at around $8.5 million. On-chain records confirm the related transfers: one transaction transferred 2,841.74 WETH to an address labeled "Term Finance Exploiter 1" by Etherscan, while another transaction transferred 1.68 million USDC to an address labeled "Term Finance Exploiter 2".Yearn stated that Term's vault contract uses its V3 architecture, but the attack occurred on Term's custom governance wrapper, which is not applicable to standard Yearn vaults. Term indicated that, according to the current investigation, its underlying protocol and direct lending market were not affected and is working with external security teams for remediation and recovery, but did not provide any compensation commitments or timelines.

Strategy has annual liabilities of approximately 1.76 billion USD, with 66.7 billion USD in Bitcoin holdings relying on capital market financing

The Bitcoin treasury company Strategy currently has a Bitcoin holding valued at $66.7 billion, with annual obligations such as preferred stock dividends and interest amounting to approximately $1.76 billion. Regime Intelligence analysis shows that the company's 840,447 Bitcoins correspond to about $22 billion in debt and preferred claims, making continuous access to capital markets for financing the basis for its performance.Stress tests indicate that the Bitcoin price would need to drop by about 96% for Strategy's Bitcoin holdings and reserves to be insufficient to cover convertible bonds; its debt is not traditional Bitcoin collateral margin loans, and there is no BTC margin call mechanism triggered by price declines. Report author Sherif Saad stated that Strategy needs to maintain a financing cycle to cover annual debt and preferred stock expenses, with cash reserves currently covering about 2.6 times the related annual expenses. If the financing environment worsens, the company may rely more on reserves and selling Bitcoin to fulfill its obligations.Since May, Strategy has sold Bitcoin four times, with the most recent sale of 1,690 Bitcoins, with the proceeds used to pay preferred stock dividends, buy back shares, and increase dollar reserves. CEO Phong Le stated earlier this month that the amount of Bitcoin purchased by the company this year is about 25 times the amount sold, and plans to resume purchases later this year.

Analysis: The VIX curve is rising, and anxiety in the stock market is increasing as the U.S. midterm elections approach

Although Nvidia's upcoming earnings report and Federal Reserve Chairman Waller's speech at the Jackson Hole annual meeting are the main events of interest for investors this week, traders in the stock derivatives market have already begun preparing for potential volatility increases around the November U.S. midterm elections.Traders focused on volatility in the futures market linked to the VIX index have noted signs indicating that demand for hedging S&P 500 index volatility has increased before and after the elections. VIX futures expiring in September are currently trading at around 17.4, but October contracts have risen to 19, and November contracts have further increased to 19.7.Matthew Thompson, co-portfolio manager at Little Harbor Advisors, stated, "The U.S. elections are approaching, and you are entering a time window where the elections will impact the VIX. You can already see this 'backwardation' in the term structure of VIX futures."A study by analysts at the Chicago Board Options Exchange Global Markets shows that since 1945, in 80% of midterm election years, actual volatility has been higher than the previous year, with an average increase of 3.5 volatility points. In years when both the White House and Congress are controlled by the same party, actual volatility increases by an average of 6 volatility points.
