Following a successful pilot of its blockchain-powered eB/Ls platform that lasted for over a year, the shipping firm ( Zim) has claimed that blockchain can not only replace the currently existing paper-based processes, but also improve the workflow conducted via email, fax, and other channels.

Supply chain and shipping containers on Blockchain are ideal scenarios. The wonder is how to secure and solve the IOT and sensor and automation problem. RFIDs May help , but from end to end tracking and transparency is the real key.

Smart farming on Blockchain

The idea of bringing community back to farming is an interesting concept. Shop and buy local has been a trademark in certain communities spawned by the backlash against a Walmart or other big box franchise stores. Cities like Greenville, SC are already trying to foster a better localized community and startup incubator.

Smart cities and the Internet of things isn’t new. Still a work in progress though and a long way to go . But how can these small Local farms flip the script and change into a more successful community of local farmers. A Community that thrives and grows.

Smart farming is a pie in the sky dream or a realistic endeavor ? Is it organic or raw or not ? Did they use Monsanto seeds or not ? How do they distribute to the next town over? And earn income ? How do they better market, farmers markets ? How do they turn communities with limited access to fruits and vegetables and healthier food into a smorgasbord of red, greens, blues , oranges and yellows ? And how can it all be transparent and immutable ? And smarter ? And affordable?

Smarter farming. Let Pagarba show you how.

Hyperledger has added a lot of partners to their community. But what does that really mean ? Some company paid $25k and up to market the logo? That’s the challenge with alliances and partnerships. Most have little to no real value on either end.

Hyperledger Ursa will act as a repository of “trusted” cryptographic implementations, aimed to make it easier for blockchain developers within its community and the wider open-source space to avoid duplication of development efforts.

The library will lead to simpler project maintenance and cut down on bugs, Hyperledger said, with most or all of the crypto code being kept in a single location and reviewed by security experts – including developers who work on Hyperledger’s Indy, Sawtooth and Fabric projects, as well as cryptographers with academic backgrounds.

“Our goal in creating Ursa is to combine the efforts of all the security and cryptography experts in the Hyperledger community and move all of the projects forward,” Hyperledger said. “

Good infograph about an STO vs ICO. The bigger challenge is it gets back to the rich get richer and average person left out concept.

Blockchain will keep you young …

Can Blockchain help you stay young ?

Maybe, maybe not but here are a few ways to look and feel younger….

  • Exercising and staying active
  • Learn a new skill or language
  • Sleep
  • Well balanced diet
  • Friends and family

Exercising and staying active

It’s well known that any kind of exercise, whether 20 minutes a day or a walk up the stairs, helps you stay healthy and young.

In fact , exercising helps your brain remove proteins like amyloid. This is one of those proteins that accumulate over time and some believe play a part in Alzheimer’s or make those with Alzheimer’s worse. And there hasn’t been a drug that lowers amyloid.

Blockchain and exercise….

maybe with a Fitbit and some heart-rate sensors that monitor whether your heartbeats faster or slower, maybe written to the Blockchain. Possibly obtain rewards with a token or bitcoin for more steps , better heart rate , cholesterol, etc. maybe some amyloid like sensor. If possible.

So there is a use case for Blockchain here.

Learn a new skill or language

There is a ton of research around challenging your brain to reduce your risks of dementia. But how complex does the challenge have to be to reduce dementia? Learn mandarin at 75? Learn cryptography at 65? Learn how to salsa dance at 90? Skydive at 100? And how often , how much is needed ?

Finding new activities that interest you and trying to get better is the important part. Your brain stays active and interested.

Instead of your brain just giving up sometimes , it’ll find alternative options because it’s always finding new challenges.

Blockchain and new challenges …

Of course learning about Blockchain, cryptocurrency, and technology is a challenge , but it serves no purpose if someone quits in a few minutes. Find something that you’ll enjoy and stick with it. And mix it up every year.

Who says a 91 year old can’t build smart contracts in solidity ? Why not. Maybe they would bring a different perspective. It might also create an adventure or new bonding experience with grandkids or great grandkids.


Sleep is something the tech space and some musicians, actors, etc brag they don’t ever need or get. But it’s well known a good nights sleep is not only good for you , but can help you stay youthful and attentive and productive.

Blockchain and sleep …

Turn off the tv. Don’t put your smart phone near your bed. Stop eating unhealthy and drinking caffeine right before bed. Do some yoga and meditation. Breathe deeply.

Sleep patterns could be stored on the Blockchain and maybe if you add smart sensors that listen to your breathing and voice and heartbeat, a Blockchain like token or bitcoin reward for sleeping better and longer could be a good incentive.

Well balanced diet

Eating more vegetables and fruit makes you healthier and younger. And is great for your memory and cognitive capabilities. A well balanced diet is key.

Stay away from saturated fats and trans fats. They damage you and your heart and your brain. Avoid fried foods.

Certain studies claim you can reduce your risk of Alzheimer’s by like 40% by eating Blueberries, raspberries, blackberries (all high in antioxidants), Leafy greens like kale , & fish. But you need to avoid things like red meat , butter , fried foods , anything with high saturated and trans fats.

There are tons of Blockchain and IOT and artificial intelligence use cases for supply chain , food , agriculture , and restaurants. Look at the recall for lettuce now.

It’s not a ‘Blockchain will save lettuce ‘ but it could be one piece of an integrated ecosystem platform that catches recalls long before people get sick or even die form poison food.

Friends and family

There are many studies that show us having a good social circle helps people live a healthier longer life. Many Studies about Grandkids and grandparents and happy kids becoming happy adults and grandparents extending their lives and being healthier. Same with good friends.

Blockchain and family

The thanksgiving dinner this year might not be a happy medium if you brought up bitcoin and crypto last year. So tread lightly. But Blockchain and Wallets and economic theory are all conversations people should have. What better way to teach various generations.

Sawtooth security

Leader selection is a major task of the consensus algorithm in hyperledger sawtooth. It helps decide which competing peer node can publish a new block on the blockchain.

What are some security implications of a consensus algorithm?

  • A secure consensus algorithm is important to prevent a “rogue” or bad actors from “gaming” the system
  • Bad actors can publish transactions favorable to it
  • A third-party can publish transactions before or in lieu of transactions from other nodes
  • Multi-tier and/or distributed applications having better timing and speed can be a distinct advantage. Think high frequency trading and Wall Street
