When it comes to keeping up with new products, services, and innovations in the tech industry, the realm of conferences and trade shows are largely dominated by the vendor/sponsors. Such is the case with VMworld, Cisco Live, EMC World, Microsoft Tech Ed, Dell World, and others. Not that there’s anything wrong with that — these vendors normally keep the events buzzing with exciting new announcements and informative events. Other vendors are invited, and a good time is had by all, yada, yada, yada.Tech Field Day represents a refreshing change. The event is deliberately set up in such a way that the attendees (who are deliberately chosen independent bloggers and freelance writers) are not obligated in any way to write or say nice things about the vendors. While Tech Field Day is an invitation-only event (you cannot buy tickets), it is immediately available to the tech world at large via video streaming and through live tweeting by the invited attendees. Here’s what Tech Field Day is, what it isn’t, and why you should care.

What Tech Field Day Isn’t

_Tech Field Day_

Unlike field day in school, this field day doesn’t come with being picked for teams last, scraped knees, sprained ankles, and grass stained pants.

Tech Field Day is not a large conference or week-long trade show at a large venue filled with thousands of attendees and hundreds of vendors. Each Tech Field Day event is comprised of a select few vendor sessions, attended by ten to fifteen delegates, plus a handful of event staff. Travel to the event and lodging during the event is paid for by the sponsoring vendors, however, these funds are pooled so that no particular vendor could be attributed to having paid the admission for any particular blogger or writer. Hence, it encourages open and honest questioning of the vendor’s presentation, as well as candid reporting of and commentary on the vendor’s presentation.

You don’t have to sit around watching the mailbox for your invite to Tech Field Day. Watch previous and current events on their YouTube channel and follow live event tweets.

Tech Field Day events are categorized into one of several niches: general tech events, virtualization events, networking events, wireless tech events, and events that focus on storage. Events are spread throughout the calendar year  and are hosted in numerous cities across the country. Most events are held in a particular vendor’s headquarters or facilities, which keeps costs down as it is not necessary to rent out huge conference halls or resort hotels.

Tech Field Day is ideal for both the vendors and the writers and bloggers. The vendors get candid, realistic feedback from the attendees. In many cases, live tweeting during the events  gives attendees the opportunity to ask questions from their followers, as well. It’s an excellent way for vendors to gauge real-world interest, understanding, perception, and acceptance of a given product or service. These events are far more intimate and less hectic and formal than are large conferences and trade shows, so it’s an excellent opportunity to get personalized input for the vendor’s ideas. 

The writers and bloggers, of course, get lots of publicity and exclusive content for their publications and blogs. For example, if a vendor has introduced a new product or service to monitor VMware, the bloggers get the first opportunity to share the news, as well as the chance to ask lots of questions and learn more about the new technology.You can see some of the previous Tech Field Day events on their YouTube channel

Use Case - Tamper-resistant Clinical Trials


Blockchain PoCs were unsuccessful due to complexity and lack of developers.

Still the goal of data immutability as well as client verification is a crucial. Furthermore, the system needs to be easy to use and operate (allowing backup, maintenance windows aso.).


immudb is running in different datacenters across the globe. All clinical trial information is stored in immudb either as transactions or the pdf documents as a whole.

Having that single source of truth with versioned, timestamped, and cryptographically verifiable records, enables a whole new way of transparency and trust.

Use Case - Finance


Store the source data, the decision and the rule base for financial support from governments timestamped, verifiable.

A very important functionality is the ability to compare the historic decision (based on the past rulebase) with the rulebase at a different date. Fully cryptographic verifiable Time Travel queries are required to be able to achieve that comparison.


While the source data, rulebase and the documented decision are stored in verifiable Blobs in immudb, the transaction is stored using the relational layer of immudb.

That allows the use of immudb’s time travel capabilities to retrieve verified historic data and recalculate with the most recent rulebase.

Use Case - eCommerce and NFT marketplace


No matter if it’s an eCommerce platform or NFT marketplace, the goals are similar:

  • High amount of transactions (potentially millions a second)
  • Ability to read and write multiple records within one transaction
  • prevent overwrite or updates on transactions
  • comply with regulations (PCI, GDPR, …)


immudb is typically scaled out using Hyperscaler (i. e. AWS, Google Cloud, Microsoft Azure) distributed across the Globe. Auditors are also distributed to track the verification proof over time. Additionally, the shop or marketplace applications store immudb cryptographic state information. That high level of integrity and tamper-evidence while maintaining a very high transaction speed is key for companies to chose immudb.

Use Case - IoT Sensor Data


IoT sensor data received by devices collecting environment data needs to be stored locally in a cryptographically verifiable manner until the data is transferred to a central datacenter. The data integrity needs to be verifiable at any given point in time and while in transit.


immudb runs embedded on the IoT device itself and is consistently audited by external probes. The data transfer to audit is minimal and works even with minimum bandwidth and unreliable connections.

Whenever the IoT devices are connected to a high bandwidth, the data transfer happens to a data center (large immudb deployment) and the source and destination date integrity is fully verified.

Use Case - DevOps Evidence


CI/CD and application build logs need to be stored auditable and tamper-evident.
A very high Performance is required as the system should not slow down any build process.
Scalability is key as billions of artifacts are expected within the next years.
Next to a possibility of integrity validation, data needs to be retrievable by pipeline job id or digital asset checksum.


As part of the CI/CD audit functionality, data is stored within immudb using the Key/Value functionality. Key is either the CI/CD job id (i. e. Jenkins or GitLab) or the checksum of the resulting build or container image.
