The San Jose, Calif.-based company submitted a patent application in June 2018 for a blockchain platform that can be natively integrated in wireless networks, according to a Nov. 26 filing from the U.S. Patent and Trademark Office (USPTO).
The blockchain platform aims to manage data sessions between an equipment user, such as a phone or laptop, and a virtual network. In other words, the new technology can manage part of the data exchanges between a network and a connected device via the blockchain interface.
The company describes how a blockchain platform can be used to support network slices, referring to an architecture that allows multiple independent virtualized networks to run in the same physical infrastructure more efficiently.
“This service-oriented architecture supports network slices, which employ an isolated set of programmable resources that can implement individual network functions and/or application services through software programs within a respective network slice, without interfering with other functions and services on coexisting network slices,” the filing said.
Cisco is among a long list of information technology companies that are exploring the integration of blockchain technologies and Internet of Things (IoT). Companies, such as Bosch, BNY Mellon, Chronicled and Filament, have used Hyperledger, ethereum and Quorum to create or upgrade their products and services.
In September, Cisco partnered with artificial intelligence services provider SingularityNet to decentralize AI systems by preventing one single source from concentrating computers’ capacity to learn through blockchain technologies. The company has also been trying to develop another blockchain technology that would create a more secure environment for group chats in a network, according to a filing dated in March 2018.

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.

Bitcoin hash rate slides during U.S. winter storm while markets shrug off mining disruption
The temporary loss of mining power underscores academic concerns that geographic and pool concentration can magnify infrastructure failures, though markets showed little immediate reaction.
What to know:
- Bitcoin’s hashrate fell about 10 percent during a U.S. winter storm, underscoring how local power disruptions can strain the network’s capacity to process transactions.
- Researchers have shown that concentrated mining, as seen in a 2021 regional outage in China, can lead to slower block times, higher fees and broader market disruptions.
- With a few large pools now controlling most of Bitcoin’s hashrate, the network is increasingly vulnerable to localized infrastructure failures, even as the price of BTC remains largely unaffected in the short term.
