What happens if someone adds incorrect entries by accident or intentionally? How do you ensure parity between the real world and the Blockchain?

you can build document versioning into a blockchain-backed protocol - I would assume that Digibuild have done this as documents can be both corrected and extended over time. The important factor being that the old version is not erased and thus you can see the history of the document, which could be beneficial.

But how do you know that what is on the Blockchain matches the real world?

This is the core to if a Blockchain can be trusted for anything which does not originate on the Blockchain.

By uploading said information you are claiming it is true. Whether other people believe it to be true depends on whether they trust you or otherwise have verified for themselves (which can also be asserted cryptographically).

No digital technology can solve epistemology and tell you what is true - but that's not the point, and blockchain applications are not unique in this.

Yes correct. The immutability and provenance of data are key characteristics that make blockchain useful here.

If you think about it, git is itself a block chain, and doesn't suffer from that issue.

Are you familiar with Karius? They turnaround a diagnosis in a day (genomic). I could imagine both assays being run on the same sample.

Yes! Karius is great. They detect resistance genes to provide antibiotic sensitivity. We monitor the metabolic rate, that is how we do it faster.

Will hospitals be able to run your assay? If they have to send out to your lab then effectively it takes a lot longer to get a result.

Hi HN, we're Ravi and Pratik of Enerjazz ( https://www.enerjazz.tech/ ). We make battery swapping stations (like gasoline stations) for electric vehicles, swapping discharged batteries with charged batteries in 2 minutes for light commercial EVs. Commercial EVs or electric rickshaws have 2 pain points. One high upfront cost of battery (can be up to 50% of the total cost of vehicle). Two, high charging downtime result…

Very good idea. Are you operating in the northeast part of india (Assam). I am from barpeta (781301) a small town in assam, india. Here charging is a big problem the ASEB electricity supply is not reliable. We sometime can not operate for battery. enerjazz can change our life.

Hi HN! We are a rather unusual team of six founders (Pei, Amit, Sunil, Jack, Bo, and Kartik) spread across India and China, building Karbon Cards ( https://www.karboncard.com/ ). We help companies in India get instant access to a corporate card. We came across this problem separately while Amit was doing VC and Sunil was running his own fintech. We saw that a startup with $1M in the bank was facing mind-numbing issue…

I currently use open.money to manage our startup. What's your pitch to move to Karbon? Also, none of the virtual cards worked with AWS. Have you checked if your cards work with AWS?

Hello Sagar,

Our cards work on AWS. On monthly basis, our cards process around Rs. 5 Crores worth of transactions on AWS. Plus, your company might qualify for flat 2% discount on your AWS bills.

There are other features as well that you would love when you switch to Karbon. Unlike other companies, we are focused on cards, and our cards are the best in the industry.

Send an email with your coordinates ( email and phone number ) to sales@karboncard.com, and we can then share additional details with you.

Hi HN. My name is Mustafa Al-Adhami. I am the founder and CEO of Astek Diagnositcs Inc. ( https://astekdx.com ). We have a platform to determine antibiotic sensitivity in one hour. Every year, 1.7 million Americans are evaluated for sepsis - and too many die while waiting days for the correct antibiotic. Imagine a one-day-old baby having to wait twice as long as they have been alive to receive accurate treatment. Or…

Congratulations.
