Privacy Policy


This page contains the privacy policy of BLOCKCHAINJOURNAL.COM. Privacy policies typically have a lot of legalese in them and so I wanted to preface this privacy policy with a plainspoken note about my personal intentions when it comes to protecting the privacy of the users of BLOCKCHAINJOURNAL.COM. I've been in the media industry for over 30 years and, as an insider, have seen the lengths to which media companies will go to track their users. I've seen it all; the buying and selling of lists, the use of retargeting technologies, IP address matching through third-party services, and so on. In many cases, the mechanisms that websites have installed to facilitate these activities have significantly interfered with the quality of the user experience. There are certain sites that I refuse to visit on the basis of all the pop-ups, browser notifications that I must block or allow, auto-playing videos, etc. It's a mess.

Here at BLOCKCHAINJOURNAL.COM, it is my intention to disrupt that mess. In particular, I'm interested in finding new ways to put the user in direct control of their personal information. For example, wouldn't it be great if users were in so much control of their personal information that they get to decide who their information gets shared with before that sharing takes place? Not just "who" in terms of broad classes of parties that personal information might get shared with, but exactly which parties on a one-to-one basis and when. In essence, you should be able to say "Yes, I'm willing to share my personal information with specific party A, but not specific party B, and when that sharing can take place." Furthermore, after granting a party access to your personal information, wouldn't it be great if you could revoke that access as well?

There are a lot of unanswered questions on how to achieve these goals. But I have ideas on how we might be able to affect that future and I have every intention of pursuing them because I and the BLOCKCHAINJOURNAL.COM team are wholly committed to not just maintaining your privacy, but reinventing how such maintenance is done.

To set the tone for this direction, you should notice how, upon visiting BLOCKCHAINJOURNAL.COM, the overall user experience is devoid of all of the awful intrusions found on other sites. Most notably banner advertisements, but also all the pop-ups and auto-playing media that just stands in the way of the reader getting to our comprehensive article content on how to use distributed ledger technology (DLT) as your business's means to digital transformation, business innovation, and industry disruption. In fact, we are dogfooding that very mission. We ourselves are looking for ways to disrupt the media industry with DLT.

However, given the current state of the Web, there's only certain ways to accomplish certain things. For example, if, after we make it possible for you to log in to our website, you want to remain logged in even after closing your browser tab (which many users like to do), we need to issue a persistent cookie to your system as a means of connecting your next visit to our site with your unique account. This approach doesn't reveal any personally identifying information to any third parties. But technologically speaking, while cookies are often used as a means of intruding on end-user privacy, cookies are also the main way to optimize the user experience for you. When BLOCKCHAINJOURNAL.COM itself issues a cookie to your system, our intention here is strictly to optimize the experience for you.

However, not all cookies that end up on your system, as a result of using our site, will be a result of cookies that BLOCKCHAINJOURNAL.COM itself delivered to your system for the purposes of giving you a better user experience. For example, we have launched a YouTube channel and will be using YouTube's technology to embed videos onto various pages of our website.

As a result of using YouTube to facilitate this part of our multimedia experience, you may find other cookies on your system that came from YouTube. It's not ideal. But that's how it works and, for the record, BLOCKCHAINJOURNAL.COM doesn't even have access to those cookies. You are of course free to block those cookies as you should be. However, blocking those cookies could also disable your ability to view the videos in their embedded form. Again, in the spirit of enabling you to engage with BLOCKCHAINJOURNAL.COM in as private a way as possible, we will look to enable workarounds to such challenges. For example, everywhere we embed a video, we will endeavor to provide a direct link to that video on YouTube. This way, you can visit the video directly on YouTube where maybe, YouTube will make it possible to view that content without forcing the delivery of a cookie.

The same arrangement may be true of other third-party services that we rely on to deliver the best user experience possible. For example, if we enable the ability to login to our site through a single sign-on provider such as Google or Facebook in order to make logging in more frictionless (and give you one less user ID and password to remember).

Just like any business that has to keep track of its business performance, we have our own metrics and KPIs that we track in order to know if we're doing a good job. For us, like other media destinations, that means reporting on the usage of BLOCKCHAINJOURNAL.COM in terms of metrics like daily, monthly, and annual page views, the number of pages viewed per visit, which pages are getting viewed more than others, etc. To facilitate this part of our business, we use Google Analytics. As a result of our usage of Google Analytics to help us better understand how our website is getting used, the Google Analytics service may issue cookies to your system. Similar to other cookies (such as those from YouTube), you are free to block the cookies from Google Analytics. We wish you wouldn't because doing so also distorts our statistics and dashboards. But, I also believe that it is you that should be fully in control of your privacy and if you deem it necessary to block those cookies, then so be it.

All this said, there are a great many circumstances where we may come into contact with your personal information in the course of running our business. For example, if you write an email to one of our editors or to our support team, then, naturally, we now have your email address. This is a good example of where we shouldn't use your personal information for a purpose other than the original context under which we received that information. For example, if you send an email to [email protected], your email address should not get used outside of the context of getting support without consent from you. We might retain the actual email in our email system only so that if you email us again, we can see the history of our support relationship with you (which in turn speaks to how we might store your email address and the nuances involved wherever a privacy policy mentions something like the storage of personal information).

The long-winded point I'm trying to make here is that I believe when it comes to respecting your privacy, my intention is to handle your personal information in the same way that I personally wish all businesses would handle my personal information; with the utmost care. Having been personally exposed to the inner machinations of the media industry, I have a pretty good idea of exactly what I wouldn't want done with my personal information.

All of this said, having a privacy policy is a standard operating procedure for any website. As spartan as BLOCKCHAINJOURNAL.COM is when it comes to putting cookies on your system or using "web beacons" (typically used with email newsletters, a feature that was not offered at the time the website was launched) and other mechanisms that readers might consider to be intrusions on their privacy, there may come a time when we introduce them for the various intentions stated above. So, for those reasons, here is a privacy policy that accounts for both current and forward-looking scenarios. I welcome your feedback at [email protected].

David Berlind 


BLOCKCHAINJOURNAL.COM ("the Service") is a wholly-owned subsidiary of Swirlds Labs Inc. This BLOCKCHAINJOURNAL.COM privacy statement ("Privacy Statement") describes the privacy practices of the Service.

When our terms and conditions use the words "we," "us," and "our," we mean the Service. When this privacy policy speaks of "you" or "your" it means anyone who uses the Service.

Please read this Privacy Statement carefully and thoroughly to learn how we may collect, use, share and otherwise process your information ("Personal Data"), and your rights and choices regarding our processing of your Personal Data.


This Privacy Statement applies to the following processing activities:

  1. Visiting the Service or using an authorized application offered by the Service (e.g.; an application offered specifically by the Service through an app store) which displays or links through to this Privacy Statement 
  2. Registering or attending physical or online events that are produced or sponsored by BLOCKCHAINJOURNAL.COM

The Service may contain links to other websites, applications, and services maintained by third-parties. The information practices of such other services are governed by third-party privacy statements, which we encourage you to review to better understand those third-parties' privacy practices.


  1. Personal Data we collect directly from you:

    The Personal Data that we collect directly from you may include the following:

    if you express an interest in obtaining additional information about our services, request customer support, use a "Contact Us" or similar feature offered by the Service, register to use the Service, sign up for a physical or online event, or download certain content, we may require you to provide us with your contact information, such as your name, email address, account ID, account alias, or distributed ledger-related wallet ID;

    if you attend an event that is produced or sponsored by the Service (e.g.; conferences, hackathons, meetups), we may, upon your consent, scan your attendee badge or your personal QR code (associated with an account that you control on a third-party service such as LinkedIn), require an online registration form, collect your business card, ask for hard copy sign-ups, which may provide us with one or more of the following: name, title and company name, address, country, phone number, and email address;

    if you use and interact with the Service, we may automatically collect log files and other information about your device and your usage of the Service through cookies, IP-addresses or other identifiers, which may qualify as Personal Data (view the "What device and usage data we process" section below);

  2. Personal Data we collect from other sources:

    Where the Service relies on integration with other online services for specific end-user features and functionality (including but not limited to third-party single sign-on services), we may collect information about you from those third-parties to better facilitate the provision of the Service and all of its features and functions to you.


We use common information-gathering tools, such as log files, cookies, and similar technologies to automatically collect information, which may contain Personal Data, from your computer or mobile device as you navigate the Service or interact with emails we have sent you.

  1. Log Files:

    As is true of most websites, we gather certain information automatically via log files. This collected information may include your Internet Protocol (IP) address (or that of your proxy server), device identifiers, your location, your browser type, your Internet service provider and/or mobile carrier, the pages and files you viewed, your searches, your operating system and system configuration information, and date/time stamps associated with your usage. This information is used to analyze overall trends, to help us provide and improve the Service and to guarantee their security and continued proper functioning. We may also collect IP addresses from users when they log into the Services as part of the Service's security features. To the extent that we use third-party services to provide the best possible user experience to you, including but not limited to third-party analytics services or third-party content delivery network (CDN), those third-party services may collect the aforementioned information in this section (section 3a) in their logs. For analytics, the Service uses Google Analytics. For CDN capabilities (to offer the best performance of the website), the Service uses Cloudflare. Users of the Service are encouraged to review the privacy policies of these and other third-party services that we rely on.

  2. Cookies and other tracking technologies:

    We use cookies, tags, and Javascript alone or in conjunction with cookies to compile information about usage of the Service.

    When you visit the Service, our servers or an authorized third-party may place a cookie on your browser, which can collect information, including Personal Data, about your online activities over time and across different sites. Cookies allow us to track overall usage, determine areas that you prefer, make your usage easier by recognizing you and providing you with a customized experience.

    We may use both session-based and persistent cookies. Session cookies exist only during one session and disappear from your computer when you close your browser software or turn off your computer. Persistent cookies remain on your computer or device after you close your browser or turn off your computer. You can control the use of cookies at the individual browser level, but if you choose to disable cookies, it may limit your use of certain features or functions on the Service. We use Google Analytics to measure and improve the Service and offer the ability for users of the Services to reject cookies that Google Analytics serves to your device. To opt-out from tracking by Google Analytics, please use the specific opt-out mechanism as indicated further below.

    We may also place web beacons in emails that notify us when you click on a link in the email that directs you to the Service. Such tracking technologies are used to operate and improve the Service and measure the clicking of links or opening of emails.

    The following sets out how we use different categories of cookies and similar technologies, as well as information on your options for managing the settings for the data collection by these technologies:

    Required Cookies: 
    Required cookies enable you to navigate the Service and use its features, such as accessing secure areas of the Service.

    If you have chosen to identify yourself to us, we may place on your browser a cookie that allows us to uniquely identify you when you are logged into the Service and to process your online transactions and requests.

    Managing Required Cookies: 
    Required cookies are essential to operate the Service and there is no option to opt-out of these cookies. Please refrain from using our site if you do not consent to these cookies.

    Functional Cookies: 
    Functional cookies allow us to remember information you have entered or choices you make (such as your account ID, account alias, language, or your region) and provide enhanced, more personal features.

    Functional cookies may also be used to improve how the Service functions and to help us provide you with more relevant content. These cookies collect information about how the Service is used, including which pages are viewed most often.

    We may use our own technology or third-party technology to track and analyze usage and volume statistical information to provide enhanced interactions and more relevant content.

    In particular, we use Google Analytics, a web analytics service provided by Google, Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA as our processor. Google Analytics uses cookies to help us analyze how the Service is used, including the number of visitors, the websites visitors have come from, and the pages they visit. This information is used by us to improve the Service.

    We also use Cloudflare CDN, a content delivery network service provided by Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA as our CDN. Cloudflare may currently or at some point in the future use cookies or collect IP addresses to perform its function. This information may be used by us to improve the Service.

    Managing Functional Cookies: 
    To manage the use of functional cookies on the Service, consult your individual browser settings for cookies. Note that opting out may impact the functionality you receive when using the Service. For example, if the Service relies on a third-party service such as YouTube for video content playback, disabling the receipt of cookies from YouTube may disable the Service's video display and playback features. We also endeavor to provide such opt-out capability through a cookie consent feature and will make every reasonable effort to ensure the proper functioning of the feature. Per our Terms of Service, we do not guarantee the feature's feature's availability or proper functioning at the time(s) of your visit to the Service.

  3. Opt-Out from the collection of device and usage data:

    You may opt-out from the collection of device and usage data (see "What device and usage data we process" section above) by managing your cookies at the individual browser level. Please note, however, that by blocking or deleting cookies and similar technologies used on the Service, you may not be able to take full advantage of the Service.

  4. Social Media Features:

    The Service may use social media features, such as the Facebook "like" button, the "Tweet" button and other sharing widgets ("Social Media Features"). You may be given the option by such Social Media Features to post information about your activities on a website to a profile page of yours that is provided by a third-party social media network in order to share with others within your network. Social Media Features are either hosted by the respective social media network or hosted directly on the Service. To the extent the Social Media Features are hosted by the respective social media networks, the latter may receive information that you have visited the Service from your IP address. If you are logged into your social media account, it is possible that the respective social media network can link your visit to the Service with your social media profile.

    The service may allow you to log in using single sign-in services such as those offered by Google, Facebook and other third-party single sign-on providers. These services may authenticate your identity and provide you the option to share certain Personal Data with the Service such as your name and email address to pre-populate a sign-up form.

    Your interactions with Social Media Features are governed by the privacy policies of the companies providing the relevant Social Media Features.
