Digital Currency and Blockchain Explained: The Good and the Bad

Are you curious about how digital currencies and blockchain technologies work? These two technology giants are changing the face of many essential industries and won’t be leaving the digital frontier anytime soon.

Digital currency is a decentralized financial system that utilizes nodes to verify digital transaction requests and blockchain to permanently record verified transactions. A transaction can include cryptocurrency, contracts, records, or other information.

Here’s how a digital currency transaction and blockchain work together to create a permanent transaction:

1. Someone requests a digital transaction.
2. The requested transaction is broadcast to a P2P network of computers known as nodes.
3. The transaction is verified when the 64 alphanumeric target is guessed by a node.
4. Once verified, the transaction is combined with other transactions to create a chain of data to create a new block of data for the ledger.
5. The new block is then added to a chain of verified data blocks, the blockchain, in a way that is permanent and unalterable.

And that’s it! Here’s an infographic on the digital transaction verification process:

The Good

Digital currency and Blockchain are truly revolutionary technologies touted as a democratic solution that unhinges financial and other transactions from any one government or one currency system. Blockchain records are unchangeable, permanent, and verifiable records that theoretically will exist forever as a part of the chain created.

Many different types of digital currency exist. You’ve probably heard of Bitcoin, Dogecoin, Ethereum, or the growing handful of other popular digital currencies currently taking over the market. They each make their claim that they are the best.

The same is true of blockchain verifiers - there are many permanent blockchain records already created. They also each claim to be the best in some way. Some blockchains allow you larger storage blocks and some are quite limited at 2MB of verified data block size. Some blockchains offer the person conducting the transaction complete privacy of who they are to others; while other blockchain records are completely public, showing who initiated the transaction, the type of transaction, and the blockchain sequence identifier.

These blockchain verifiers each have a number of minors independently working to verify their transactions. The verification process is a little bit like a guessing game. A random 64 digit alphanumeric code is generated and the winning miner has to essentially guess the 64 digit alphanumeric number that is closest to that target number, winning the digital currency value for that verified block of information. A 64 digit alphanumeric code allows for millions of possibilities to guess.

Blockchain is creating an ecosystem for projects in currencies, developer tools, sovereignty and security, financial technology, currency exchange, sharing data and amassing big data, and identity authentication. These named project types are just the start of the many possible technologies growing out of blockchain technology.

The Bad

Even with all of the benefits that bitcoin Blockchain technologies bring, there are still some negatives that need to be solved. One of the primary negative aspects of all the mining activity is the generation of copious amounts of computer hardware waste and the large amounts of energy consumed to power these super-processing computers.

A regular everyday business or home computer is not capable of mining for bitcoin as the market currently stands. In order to even compete to win a blockchain validation, the miner needs a powerful gaming-type computer processor and most likely you will need many of these machines in a network together to generate the computing power necessary.

All of this computing power uses a lot of energy. And building all of the computer chips, which only lasts for a few years, creates a lot of additional waste. Digital currency miners are quite open about the cost to continually change out their computer processors for newer, faster chips; the power needed to run those machines, the power needed to cool the room that the computers are kept in, and the subsequent waste being generated by their quest to mine [to guess numbers and validate digital transactions] faster than the next miner, and ultimately win the digital currency bounty.

Digital currencies and blockchain technologies hold many opportunities for our future, if they can get over the hurdles of waste generation and energy consumption that they face today.

First Carbon Net Zero Soccer Game: Tottenham Hotspurs vs Chelsea 9.19.2021

Sports bring us together. They give us entertainment and they allow us to settle our political differences in ways other than wars. In almost every American household there is at least one sport regularly playing on the television. In our house that sport is football -- or "soccer" as us Americans know this sport by.

Popular all around the world and huge in every country other than the United States, soccer has been a catalyst for youth in some of the poorest places of the world. It’s popular in these poor places because of tradition but also because it only takes a simple ball and a small target to use as a goal, whereas other sports usually take much more gear or need more people on the team to be a good game.

One of the largest and most well-funded soccer leagues, with some of the best players in the world, is the English Premier League in the United Kingdom. The Premier League and Tottenham Hotspurs Football Club recently made an exciting sustainable leadership choice: to hold the first ever carbon net zero soccer game between teams Tottenham and Chelsea on September 19, 2021. Tottenham Hotspurs partnered with Sky news and the UK government to tackle this monumental reduction in carbon footprint and to bring attention to the climate emergency we're all currently fighting.

Tottenham Hotspurs Football Club Stadium

Carbon net zero status for events and buildings means that the emissions of carbon produced by that venue has been calculated and that sustainability strategies have been put in place to reduce the carbon being generated to zero, with nothing harmful being emitted into our planet's environment.

Calculations for carbon emissions for the soccer game would have captured everything from how the stadium is powered, how far the food travels to get to the stadium and how it is grown; emissions created by how players and attendees travel to the game; and impacts of the water used throughout the stadium. Greenhouse gas emissions calculations are a very complex data gathering and analysis process with many different indicators weighing in on the carbon emissions calculation.

Sustainability efforts are also incomplete without social justice as a key component. The Premier League, its players, and staff are already well known for their progressive support of human equality.

Carbon zero status was achieved through many different methods for the Tottenham-Chelsea soccer game, including the purchasing and planting of carbon offsets. Offsets will unfortunately always need to be used for large scale events and structures to reach carbon net zero status no matter the reduction techniques used, so this isn’t something we’re going to change soon.

Some of the techniques that Tottenham Football Club used to make this a sustainable soccer game were reducing the overall energy usage to power the game and using sustainable sources for energy; encouraging proper waste management and recycling; and making dietary choices at the stadium that reduced travel distance of food and encouraged meatless or meat-alternative options. The club also encouraged their fans to make sustainable choices, such as taking transportation to the games in a way other than driving and to consider water conservation at home and at the stadium.

What’s really exciting is that the Premier League even chose to promote sustainability in this way. With millions of viewers across the world watching their games they can really make a statement about issues essential to human kind.

Remember that even really big things begin with really small steps: How can you positively affect our resources and our planet? Can you be a little more conscious about water or energy use throughout your day? As Gandhi once said, change begins with me. Changing our own behavior is the only effective route to saving our planet.

If you want to change the world, start with yourself.
Mohandas Gandhi

Tottenham Hotspurs soccer players and staff are passionate about their climate goals for the planet, calling themselves the Premier league‘s greenest club. Great job, Tottenham Hotspurs, for setting the new standard for soccer games around the world!

Hiking at Turkey Creek (Gainesville/Alachua)

Nestled between the Gainesville-Alachua area, the Turkey Creek trail system is a little gem of North Florida. Horse riders, bikers, hikers, and dog walkers are all welcome on these trails. The main trail we traveled through the woods on was 2.5 miles long and had an elevation change of over 85 feet. Rated as “easy” due to the broad, even surfaces on the main trails; the elevation change did make this trail a little more challenging than easy.

Peeking from under a mushroom.

The day we went hiking it had been raining off and on over the last month and the trails were still a little damp. One section of the main trail Turkey Creek actually passes over the roadway so we had to hop over the water. The trail has adequate shade for the majority of the hike.

This is really one of the best trail systems in the Gainesville area. Pick a day to visit when it hasn’t rained too much in the previous week and make sure to wear bug spray - there are definitely a lot of swarming mosquitoes and horseflies as you get into boggier (lower elevation) areas.

This is the bug spray I use:

Buy OFF! Deep Woods Bug Spray (2-pack)

 

Along the trail there are several sinkholes and deep washes where water has cut through the terrain. Since Gainesville has had quite a bit of rain over the summer there were also many different kinds of mushrooms growing everywhere in the damp ground.

 

White, wavy mushrooms cover this fallen log.

 

Another huge mushroom.

 

We even saw a family of four deer while we were there: a small buck, a doe, and two fawns hiding just off the road. The buck and doe stood just breathing and looking at us about 10 feet from our vehicle - they were small deer, but truly beautiful to see wildlife so close. Other reviewers have noted seeing turkeys, deer, snakes, alligators, and even bobcat while hiking Turkey Creek.

Two deer by the side of the road: a small buck and a doe.

In addition to the main broad, easy trail; there are many side trails and cut-throughs that are not as well-maintained, but still passable if you are on horseback or mountain bike. There’s even a fitness course that cuts through the middle of the park with fitness equipment installed along the route. We will definitely be coming back with our mountain bikes so that we can take some of the side trails more easily and cover more ground to get to some of the back trails.

You might want to bring a hiking stick with you when on foot at Turkey Creek. A hiking stick would come in handy in some of the higher grass areas or if you ran into some of those poisonous snakes that are advertised everywhere. I almost always carry a hiking stick for snakes or wild animal protection as dangerous situations can arise quickly when you’re out in the wild.

This is the hiking stick I recommend:

Buy Hickory Wood Hiking Stick

I also bring a fanny pack with my phone, keys, and water. A fanny pack doesn’t hold heat against your body like a backpack does, it provides plenty of caring space, and you’re still hands-free.

This is the exact fanny pack I carry (blue/yellow camo):

Buy Blue/Yellow Camo Fanny Pack

Here's a red/grey camo version:

Buy Red/Grey Camo Fanny Pack

 

If you haven’t hiked this really neat trail in the Gainesville area yet, then I highly encourage you to make a trip. It’s so quiet and rural while you’re on the trails that you don’t hear any traffic. It’s a peaceful slice of Florida that you have to visit!

A large tree had fallen across the main trail.

Online Learning, A Pandemic Bandaid

I was hopeful when all of America collectively implemented online learning last year - that people who had never tried it before may come to like it and find it efficient for teaching and learning - but instead the application was poor and many students did not achieve the learning gains possible. Online learning has pretty much been badmouthed in the media - but yet here we go again, rushing to remote learning due to the new rise in more dangerous Covid variants.

Online learning is not for everyone?

Now as another in-person school year is threatened by the Covid delta variant, the same students will be rushed into an online learning system that could produce less than mediocre learning results (and probably being implemented by the same staff badmouthing online learning). It’s normal to be frustrated with technology - but I encourage you to give online learning a try with a fresh perspective and utilizing the tips below.

Through modern curriculum design methods, online learning should be successful for most learners with the proper supports, like having trained teachers (teachers properly trained to support online learners, and who are not overloaded with in-person teaching duties at the same time) and reliable learning management systems. Online learners that are successful are also typically self-motivated and strong readers (usually English is necessary but ESOL programs are available too).

Supporting online learners

To support this rushed transition to online “remote” learning with these students:

Support and structure learning for self-discipline. Use regular turn-in intervals for assignments, predictable activity schedules, mandatory in-person check-ins, a clear agenda posted for each unit, predictable assignment successions, succinct rubrics that are shared in advance of the assignment, and apply metacognitive strategies to maximize your students’ learning. 

Humanize the online environment and build authentic connections. This is really the most important tip - if you don’t build instructor-to-student support, peer-to-peer community, and learner-to-content personal connection; then prepare for your learners to check out from your lesson. Learners are motivated and build connections while learning in an online environment through these elements - these authentic, humanized connections are what we all need in the online environment. 

Create clear instructions. Try to be succinct and don’t be superfluous with your word choices. Sometimes a video is needed to explain an assignment, which is also a chance to build instructor presence. State your instructions starting with a directional verb: look at what is used in this article, telling you to “support,” “humanize,” "build," “create,” and “remember.” Have someone else proofread your instructions (if appropriate, an advanced student in the class) or at least read them aloud to yourself. You could also work in community with other instructors to provide support for each other.

Recognize that every learner is different and will need varying levels of interaction and support to grasp the lesson. The learners that already lack support to be successful in a traditional in-person classroom: these students will likely need the most instructor support on a regular basis. Are you sure that your learners have reliable access to the internet and a device capable of completing the online work? Is there district or school level technical support for teachers to help ensure this access?

One last thought that’s super important about supporting students through this online transition: as we send individual students (or groups of students) home to quarantine for two weeks at a time, are we also sending meals home with them? Hunger is endemic to the children in our school systems. I don’t think this is currently being done. This program could be run similarly to the summer breakfast/lunch pickup program already run throughout the country (through Covid too). Let’s make sure these kids are being taught effectively... and being fed!

Cybersecurity Basics, Revisited

Recently I’ve received more and more of those annoying and potentially unsafe texts and email phishing attempts from scammers. It seems that these criminals had nothing better to do during the pandemic lockdown except to come up with new ways to try and trick us into giving them our personal information or possibly losing money to them.

Although I work in the technology field and I’m well-versed on cybersecurity and online safety, I myself was almost tricked into clicking on a malicious link contained in a text message and had to do a double-take to stop myself. The phishing was a simple text with something about BJ’s Club membership information, and then I remembered that I didn’t even have a BJ’s Club membership, ha ha ha. This is what the text said:

There's an update to your BJ’s club order, please review the change here: bjsclub/randomurl.us

It was such a short simple text, related to “an order that I had made” - we’ve all been shopping more online this year and I’ve definitely been using the curbside pickup option with several stores. That little scam text almost tricked me into clicking almost automatically, without thinking, on the malicious link.

Basic cyber security tips

Scammers continue to get better at trying to steal our information. Realize that attacks may come in the form of a text, an email, through snail mail, or even by phone call. How do you protect yourself when using technology or online? Here are some basic tips to increase your personal security when interacting with technology or while online:

Be cautious when using public wi-fi, including your work network. Public networks give criminals the opportunity to intercept your encrypted transmissions - including when you’re using your “secure” mobile banking app or anything else where your personal data is being transferred over the wi-fi network. Wait until you’re home to conduct your important transactions or learn how to set up a virtual private network.

Plug your own charger directly into the wall outlet, not into another device (especially when traveling or away from home). When you plug your device's charger into another person's computer (or car), that computer can access your device's files.

Use a strong password or use a password manager. I personally choose to use strong passwords AND a password manager. A good password includes several unrelated words, some capitalization differences, some numbers and also some special characters.

Examples of strong passwords:

houseGolf2@cheese32
Nail$?ice5rubiX
452cucumBer#*yoyo!

Use a 2-step login process. A two step log in requires you to verify twice before accessing your sensitive information or computer - many times you will enter a password and verify an image, or enter a password and receive a text message to confirm entry.

Use HTTPS when browsing the web. When you look in the address bar, you should see “https” in front of the website address, not “http.” This ensures that any information you send over the web to that website is encrypted and therefore less likely to be hacked.

Keep your software updated. Be sure that your computer, phone, or other device has the latest software and removes any holes that hackers might exploit. Companies are very fast push out patches, but it’s your responsibility to get them installed as quickly as you can. A sidenote to software updates - always verify the origin of your software update, because this is another hole that hackers like to exploit.

Think twice before clicking any link. Links may appear to be safe, but unless you were totally sure of the sender you shouldn’t click on it. The text in the link may even appear to be safe but could be hiding a malicious site within the link.

Backup your data. Store copies or backups of important files from your phones, tablets, computers, and any other devices. Consider setting up automatic backup schedules through the settings on your device.

Put a sticker on your laptop (or other devices). There are thousands of iPads or HPs or Androids (or whatever you use!) in your surrounding area - a sticker or other identifying alteration quickly makes your device visually recognizable from other peoples’ devices. You mark your luggage- so make sure you mark your laptop too!

Don’t answer or say “yes” to any unknown caller on an incoming phone call - the unknown caller might just be a computer recording your voice to be used maliciously around the internet. Realize that your voice and other human body identifiers are now being captured by scammers to fake your identity online.

I hope you find these simple tips helpful to your safe interactions with technology. Leave me a comment below to share your experiences of scam attempts!

Role Models

There’s been a few times in my life where I’ve needed a new direction or guidance. One of the best sources of this life guidance comes from finding role models that mirror your own personal life goals and then emulating their success to then reach your own goal success. I’m always looking for great role models, most especially female role models - - as they share the same experiences that I have, like motherhood or being a wife, and they have still built immense (and unique) success in life.

As a great financial and business leader, Warren Buffett was really my start to this role models project. His advice advocates that you model your own leadership (and goals) after the very best: find successful people to admire, then simply repeat [or improve] on their methods to success. He also strongly advocates increasing your communication skills, learning something new every day, and to stop using procrastination and excuses to hold you back. Whenever I get stuck, I go back to his basic yet powerful advice to inspire me and get my progress on track again.

Choosing role models

I’ve found that it’s helpful to choose several role models from the different areas of life that you’d like to focus your goals in. Think about the different areas of your life and for what you’d like to set goals. For me, these major life-goal areas and basic guiding questions might be:

Work: Who do you wish to model professionally?
Relationships: Who enjoys and embodies the types of relationships you seek?
Health: Who is, for you, the model of health and wellness?
Spiritual Growth: Who can serve as a model for your spiritual development?
Personal Interests: Who represents “the best” in your hobbies and areas of interest?



Lastly, remember that it’s always important to be yourself. Set goals in line with who you are and your values. As Judy Garland once said: “Always be a first-rate version of yourself instead of a second-rate version of somebody else.” The unique contributions that you can bring to the world are too precious to waste by simply being a copycat. Strive to put your own spin on projects and never give less than your best effort: You’d be cheating yourself otherwise!

The UFO Trend

**UFO and alien are used interchangeably in this article.**

Aliens are a phenomenon that I’ve always kind of been interested in, but never really believed that they were anywhere near or our corner of the galaxy. However, there’s been a lot of new evidence revealed (especially video evidence) that appears to be well-researched and it makes me start to think that maybe aliens aren’t living so far away after all.

Even if you personally don’t believe in UFOs, surely you’ve noticed the increase in TV programming and news reports on unidentified crafts increasing over the last year. The U.S. government released its first-ever report on UFO activity, acknowledging that unidentified crafts are operating in our airspace -- and that even our elite capabilities cannot track or match some of these sighted crafts.

Statistics on American UFO belief

Over the past year, it seems like there's been a big change in how many people believe in UFOs flown by beings not from this world [or from this time period, or dimension...] as credible craft sightings. A 2019 Gallup poll surveyed 1,522 random adults in the U.S. by phone and found that about 33% of Americans believe that UFOs may be alien spacecraft (https://news.gallup.com/poll/350096/americans-believe-ufos.aspx).

In addition to the traditional “aliens“ you think of, it’s possible that there are also multi-dimensional beings, time travelers, and possibly other life forms that we can’t even imagine yet, already present on our planet and possibly interacting with us, and both positive and negative ways.

The Gallup survey question and findings are below:

We have a question about unidentified flying objects, also known as UFOs. Which comes closer to your view -- [some UFOs have been alien spacecraft visiting Earth from other planets or galaxies, (or) all UFO sightings can be explained by human activity on Earth or natural phenomenon]?

 

 

 

 

 

 

 

 

 

 

Mainstream tv channels like History and Discovery channel research/document many sightings and anomalies in a balanced, scientific fashion. While there is always the possibility of exaggeration for tv or someone lying to the audience, the scientific process followed is logical and corroborated by unaltered video camera footage.

Many of these specials detail the many unexplored places on our own planet: the deep ocean, in Antarctica, and even underground. I often wonder if maybe there’s activity occurring in these hidden places where high technology, like cloaking and the ability to fly underwater, remove barriers for our [possible] alien neighbors.

An Earth-centric viewpoint

As typical of humans, we tend to hold a viewpoint where we’re at the center of whatever is going on - in our lives, when relating to the world, etc - and the UFO trend is more of the same. Why is it still difficult for many people to believe that alien life is visiting our planet, given all of the evidence that’s available? Somehow it’s more acceptable to believe that alien life is out there rather than in our own corner of space. Maybe aliens visiting or living here on Earth is a scary idea that is best kept at arms length.

“While Americans are inclined to think UFOs are not alien spacecraft, they are more apt to believe alien life forms exist beyond Earth. A June 2019 poll found 49% of Americans believing there are "people somewhat like ourselves" living on other planets. A much larger percentage, 75%, said that "life of some form" exists elsewhere in the universe” (also from the 2019 Gallup poll https://news.gallup.com/poll/350096/americans-believe-ufos.aspx).

Could it be possible that human life was seeded on this planet from life elsewhere a long time ago? There are many conflicting views of where human life came from (or evolved from) and the possibility of Earth being a zoo planet isn’t that far of a stretch when you view at the evidence without our Earth-centric egos.

Conclusion

Perhaps we’re being collectively prepared for a major reveal of information – and that aliens could already be very active on our planet and interacting with our U.S. government. While the 2021 government report didn’t reveal much, it does confirm that UFOs are enteing our U.S. airspace and that they’re not sure what or who they might be.

I think that having alien neighbors closer than we think and possibly being part of many species of intelligent beings could bring us closer as humans with a collective goal and shared identity... I’m curious what you think about this world-changing issue - please leave me a comment with your own opinions!
