Bitcoin’s inscriptions have been added to the National Vulnerability Database (NVD), which highlights them as a security vulnerability that played a key role in the creation of the Ordinals Protocol last year.

Investment manager VanEck’s proposed spot Bitcoin exchange-traded fund (ETF) would carry the ticker “HODL,” according to a recent filing with the U.S. Securities and Exchange Commission (SEC) in a nod to retail investors.

Leading stablecoin issuer Tether has frozen the wallets of those sanctioned by the U.S. Office of Foreign Asset Controls (OFAC) in a bid to “proactively prevent any potential misuse of Tether tokens and enhance security measures.”

US National Vulnerability Database Adds Bitcoin Inscriptions

Bitcoin’s inscriptions have been added to the National Vulnerability Database (NVD), which highlights them as a security vulnerability that played a key role in the creation of the Ordinals Protocol last year.

The NVD's records indicate that certain versions of Bitcoin Core and Bitcoin Knots are susceptible to a datacarrier limit bypass, which allows data to be disguised as code. The document mentions that the issue was exploited in the real world by Inscriptions in 2022 and 2023.

The NVD’s database, which is managed by the National Institute of Standards and Technology (NIST) includes cybersecurity vulnerabilities that have been recognized, catalogued, and considered important for public awareness.

The vulnerability of Bitcoin’s network is being examined. One possible consequence is that the blockchain could be flooded with large amounts of non-transactional data, which could inflate the network size and negatively impact transaction speed and fees.

The NVD’s website showcases a recent post from Bitcoin Core developer Luke Dashjr on X (formerly Twitter), in which Dashjr says that inscriptions use a Bitcoin Core flaw to spam the network.

If the flaw is patched, Ordinals inscriptions on the network would no longer be possible, although existing inscriptions wouldn’t be affected.

VanEck Proposes Bitcoin ETF to Trade Under ‘HODL’ Symbol, SEC Filing Shows

Investment manager VanEck’s proposed spot Bitcoin exchange-traded fund (ETF) would carry the ticker “HODL,” according to a recent filing with the U.S. Securities and Exchange Commission (SEC) in a nod to retail investors.

The firm’s amended Form S-1 filing states that shares of the ETF are “expected to be listed for trading, subject to notice of issuance, on the Exchange under the ticker symbol 'HODL.”

Various companies, including major asset managers BlackRock and Fidelity, have filed to launch a spot Bitcoin ETF in the United States. The SEC hasn’t yet approved any such funds, but has held meetings with representatives from these funds to discuss technical aspects of their proposals.

Tether Freezes OFAC-Sanctioned Wallets

Leading stablecoin issuer Tether has frozen the wallets of those sanctioned by the U.S. Office of Foreign Asset Controls (OFAC) in a bid to “proactively prevent any potential misuse of Tether tokens and enhance security measures.”

The firm noted that any new wallets added in the future to the OFAC list will be frozen along with the existing wallets. The move comes as seemingly one of the first significant decisions from CEO Paolo Ardoino who took helm this month.

Although Tether has previously frozen funds linked to illegal activities, the company was hesitant to freeze wallets interacting with the sanctioned Tornado Cash protocol, citing a lack of formal requests from U.S. law enforcement

However, following its recent announcement, blockchain data shows that Tether has now blacklisted the contract addresses associated with Tornado Cash.
