Walmart has yet another delivery-focused blockchain patent in the works.
The application published on July 5 is entitled "Delivery Reservation Apparatus and Method," and as suggested, it outlines a way for managing package reservations in the context of the purchaser not being available to actually receive it.

It's the latest "smart delivery" intellectual property play from the retail giant, which in the past year has submitted a number of U.S. patent applications in this area. Indeed, the company seems to be looking at the technology as a way to automate elements of the delivery process, but to date, much of the company's public-facing work with blockchain has been focused on food supply chain tracking.
In the newly released filing, Walmart detail system of delivery lockers – located at a person's home, transportation hub or other location – that can safeguard the delivered items until their recipients can come and actually sign for them. Blockchain fits into the conceived picture as a method of connecting those lockers in order to track which ones are occupied and which ones are free to be used.
"Each space on the docking station has a corresponding capacity unit for each location on the docking station. The transactions for the capacity units are tracked in a ledger, with available capacity units indicating an open location on the docking station or contracted out capacity units indicating that either the location has a locker secured thereto or that the location is reserved for a future delivery," Walmart wrote, going on to add:
"In some embodiments, the docking stations utilize a blockchain reservation system. As such, each docking station can be a node within a blockchain network."
The application makes frequent reference to a "public ledger," suggesting that the proposed system would be openly accessible to some extent rather than closed off to certain participants. That leger, according to the filing, "contains a record of available and reserved capacity units for the plurality of locker docking stations."
This perhaps suggests that Walmart wouldn't necessarily be the only operator of these docking stations, and possibly is aimed at enabling a degree of participation by outside parties.

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

Silver nears $1 billion in volume on Hyperliquid as bitcoin remains frozen: Asia Morning Briefing
Silver perps have more volume on Hyperliquid than SOL or XRP.
What to know:
- Silver futures on the Hyperliquid crypto derivatives exchange have surged to become one of its most active markets, ranking just behind bitcoin and ether in trading volume.
- The SILVER-USDC contract’s high volume, sizable open interest and slightly negative funding suggest traders are using crypto infrastructure for volatility and hedging in macro commodities rather than for directional crypto bets.
- Bitcoin is holding near $88,000 in a "defensive equilibrium" with cooling ETF inflows, uneven derivatives positioning and rising demand for downside protection, while ether lags and capital rotates toward hard assets like gold and silver.
