Will blockchain and IoT cybersecurity emerge with defenses?

With the rise of ransomware attacks demanding cryptocurrencies, will blockchain and cybersecurity emerge with defenses based on cryptocurrency technologies in the near future?

Surely the attacks are not on blockchains or Bitcoin, but on computers running vulnerable Microsoft software.

I don't really see what kind of blockchain solution can help with ransomware. Perhaps one of those decentralized clouds, but other then that, not really.

Yes, the attack was not on block chain or bitcoin but the attack was on bitcoin/crypto currency users and nothing about the malicious was mention before the existence of crypto currency.

The issue is topical and judging by this news IBM there are work in that direction:

IBM Files Patent For Proof-Of-Work Protocol Tailored To IoT Networks
Smart PlanetApril 27, 2018

Tech giant IBM has filed a patent for an Internet of Things (IOT)-focused Blockchain configuration which would tailor the proof-of-work (PoW) protocol in order to address potential security issues in IoT networks, in an application published April 26.

The patent proposes:

“A method, comprising: determining a proof-of-work via an [IOT compatible] device; using a predefined set of nonce values when determining the proof-of-work; storing the proof-of-work on a blockchain; and broadcasting the proof-of-work as a broadcast message.”
Nonces are used in PoW systems to vary the input to a cryptographic hash function so as to obtain a hash that fulfills certain conditions. IBM’s idea to restrict a nonce - literally, a “number that can only be used once” - to a predetermined range could potentially solve two challenges currently facing Blockchain solutions for IoT networks.

IoT devices are embedded with software, sensors and network connectivity, and a Blockchain solution could decentralize the interaction between these devices as well as enable them to execute smart contracts.

Many IoT devices - for example an IP-enabled doorbell of a smart dishwasher - are however “low-power” devices, meaning that they don’t have enough computational power to compete with dedicated mining devices, such as application-specific integrated circuits (ASICs). A network of such devices that would deploy a proof-of-work protocol thus faces a problem of being unable to conduct resource-intensive PoW calculations and at the same time remain secure from malicious external actors, as IBM describes:

“Most IoT devices are constrained in the amount of energy they can consume. To enable such low-power devices to compute proof-of-work for smart contracts, the complexity of a crypto-effort or crypto-puzzle should be reduced. However, reduction in the complexity of the crypto-puzzle can enable malicious participants to manipulate the smart contracts.”

i really agree with that opinion, that IoT and Blockchain it is a perfect match for future.
What you think about it ?

IoT, Blockchain, AI, Big Data etc will all eventually merge into the same thing.

You can't have Big Data analysis without AI, you can't gather enough data without IoT, you can't have a secure IoT without blockchain.
