- Lightning Network Fix Blocks Probe Linking Private Channels to On-Chain Funds — this brief
The Lightning Development Kit (LDK) has introduced a new fix to enhance user privacy on the Lightning Network. This update, released on October 25, specifically addresses a probing technique that could link private payment channels to on-chain 
Bitcoin addresses.
The probe in question required connections to both endpoints of an unannounced channel to perform a funding-location lookup. The LDK's recent update rejects this lookup, effectively blocking the probing technique and preventing the exposure of private channel information.
This development is particularly significant given the increasing use of the Lightning Network for faster and more private Bitcoin transactions. The fix ensures that users can maintain the privacy of their payment channels without the risk of their on-chain Bitcoin addresses being exposed.
According to DeFiLlama, the total value locked (TVL) in the Lightning Network currently stands at $247.66 million, marking a 9.6% decrease over the past week. This decline may reflect broader market conditions, as the overall crypto market remains relatively flat.
Bitcoin's price is currently at $77,270, with a 24-hour decrease of 0.64% and a 7-day decrease of 3.35%. The total crypto market cap is $2.66 trillion, and the Fear & Greed Index is at 26, indicating a state of 'Fear' among investors.
Since this brief published about 2 hours ago, Bitcoin (BTC) has moved from $77,270.00 to $77,705.00 — +0.56%.
The chart plots BTC's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from TLT's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
At today's peer-to-peer rate, 1 BTC ≈ ₦107.47M (about $77,705.00), up 0.5% over 24 hours. The naira itself trades about 2.8% above the official rate on the P2P market, so a Nigerian buyer's effective cost differs from the headline dollar price.
