Local Academy Becomes World’s First Martial Arts School to Secure Black Belt Records on Blockchain.

(Aurora, CO) – The Korean Academy of Taekwondo has become (as far as we can see) the world’s first martial arts school to use the power of the Ethereum blockchain to secure their black belt records. KAT Headmaster Bill Pottle explains: “The motto of our school is ‘a mind in the future and a heart in the past‘ so we are always looking at how new technology can benefit either our training or operations.”

Ethereum’s blockchain basically forms an ‘unhackable’ world computer, where transactions are verified by miners solving complex mathematical equations. The system is generally considered secure because of the expense in generating enough power to control 51% of the network – recent estimates suggest that such an attack would cost over $900 million, most of which would be lost. In the near future they will transition to Proof of Stake, making such attacks even more difficult.

Basically, the records are stored and the code is run from so many different computers distributed all around the world, it is unlikely anyone could stop it before the next block comes and the system resets. Also, in the unlikely event that the school were to burn down or go out of business, the records can never be lost.

Blockchains have future applications in all sorts of fields such as storage of medical records, voting systems, resume and degree data, and more.

How to access KAT black belt records.

Accessing the records is ‘easy’, once you are on the chain. (See below for instructions on this) Simply interact with

Contract:  0x4B39691Aa835473078F40140509De6FfeC6ba500

(in the future this will be at katblackbelts.eth)

ABI : 

[{“constant”:true,”inputs”:[{“name”:”currentBBNum”,”type”:”uint256″}],”name”:”getRecordDate”,”outputs”:[{“name”:””,”type”:”string”}],”payable”:false,”stateMutability”:”view”,”type”:”function”},{“constant”:false,”inputs”:[{“name”:”hashToSet”,”type”:”string”}],”name”:”setHash”,”outputs”:[{“name”:””,”type”:”string”}],”payable”:false,”stateMutability”:”nonpayable”,”type”:”function”},{“constant”:false,”inputs”:[],”name”:”kill”,”outputs”:[],”payable”:false,”stateMutability”:”nonpayable”,”type”:”function”},{“constant”:false,”inputs”:[{“name”:”newbbNum”,”type”:”uint256″},{“name”:”newbbDate”,”type”:”string”},{“name”:”newbbName”,”type”:”string”}],”name”:”setRecord”,”outputs”:[],”payable”:false,”stateMutability”:”nonpayable”,”type”:”function”},{“constant”:true,”inputs”:[],”name”:”getHash”,”outputs”:[{“name”:””,”type”:”string”}],”payable”:false,”stateMutability”:”view”,”type”:”function”},{“constant”:true,”inputs”:[{“name”:”currentBBNum”,”type”:”uint256″}],”name”:”getRecordName”,”outputs”:[{“name”:””,”type”:”string”}],”payable”:false,”stateMutability”:”view”,”type”:”function”},{“inputs”:[],”payable”:false,”stateMutability”:”nonpayable”,”type”:”constructor”}]

How to Use:

Use the function getBBDate with the certificate number to get the dan number and date that it was awarded. Use function getBBName with the certificate number to get the black belt’s name. The function getHash() provides the hash of the full records, not just the ones used in this pilot program. This is to check that the full records file is correct.

Reading any of the records is free.

Records 197, 212, and 214 are currently filled in.

How to Get on Block Chain

There are several methods. The following is the easiest.

  1. Download the Chrome extension MetaMask. (Explanation Video – Ignore Wordcoin info)
  2. Go to MyEtherWallet.com   and read through the popups and the click on the ‘contracts’ tab and enter the info above.

2017 Fall Elementary League Results

(Aurora, CO) – The Fall Elementary Schools League Championships were held on November 18th, 2017. The League has seen exceptional recent growth, and this year’s event featured 90 competitors from twelve different schools. Due to the size of the event, the new venue was Crescent View Academy.

Each year, it is getting more and more difficult to win in the league. CVA showed a great ‘home field advantage’, earning 52 points to take first place. Montessori Del Mundo came in second with 47 points. To put that in perspective, both of those totals were more than any other team (except one) has ever scored in an entire year. 

The tournament was held in both the cafeteria and the gym. The cafeteria provided two floors of stadium style seating for parents and spectators.

The championship features 4 separate events. In the Forms competition, students try to perform a set pattern with a high level of technical accuracy. In the Breaking competition, students create a routine where they destroy boards of varying thicknesses with a combination of different techniques. In Sparring, students earn points for kicking and punching their opponents. In Grappling, students try to hold others down or force them to give up. 

Although the competition is fierce, sportsmanship and cooperation is stressed over results. Students know that their primary goal is to become stronger as a person and help others to do so as well.

 

 

Here are the team standings so far. Trophies will be awarded for the final standings, which will also take into account the White Tiger Championships on April 28, 2018.

2017 Lone Wolf Classic and Colorado Elementary School League.

(Aurora, CO) – The 2017 Lone Wolf Classic was held at Aurora Quest Academy on April 22nd, 2017. Improbably, it once again snowed, although this time it was just early in the morning during setup. After asking “What are the odds” so many times in a row, Master Bill Pottle actually calculated the odds conservatively at 1 in 500.

Nonetheless, the tournament was a great success, with 315 competitors and participants registered from 3 countries and 5 states. The new event this year was Totem Forms, where one person does the hand techniques of a form while the other does the stances. Although there were only 8 competitors, it garnered a lot of compliments and applause.

Master Kunkel’s ALL TKD continued their streak of demo team victories, defeating Team Xtreme in the Championship Demo Division.

Elementary League Results – . In our 6th season, we have a new champion! Congratulations to Ins Paola Andrea and MDM Taekwondo! Although they were the clear winner, the competition for 2-4th places was fierce, with only a couple of points separating the winners. Congratulations to CVA Taekwando Team, Aurora Quest TKD, and Carbon Valley Academy (under Ins. Dean Leverett). These are just the top 7 teams.

 

 

All in all the tournament was a positive experience for those who participated. The Phoenix Medal was a big hit, and may make a comeback. Next on tap is the 2018 White Tiger Championships!

Historic Event Coming to Denver

(Denver, CO) – There will be several historic events coming this June to Denver, CO, timed to coincide with the US Open Taekwondo Hanmadang. (www.usopentkd.com)

The Kukkiwon is celebrating its 45th anniversary, and is working together with the Korean government and the US Taekwondo Centers to give tremendous opportunities to US Taekwondo instructors. There will also be many, many, senior martial artists in attendance.

Special Promotion Test – They will hold a Special Promotion Test which will feature regular promotions of all Dan ranks, including 8th and 9th Dans. This is the first time this has ever been held outside of Korea. They will also hold a ‘skip dan’ testing, which is for people whose masters never ordered their Kukkiwon certificates, or for other special circumstances. The test is on Thursday, June 15th. Everyone doing the Special Promotion Test must also attend the Master License Seminar.

Master License Seminar – The Kukkiwon will also hold a training for all instructors. The seminar will cover proper techniques, as well as how to teach them to students. The seminar will be on Friday, June 16th and Saturday, June 17th. The seminar is usually $350, but in this case it is only $200. They are also offering 2 nights in the hotel as well as 2 banquet dinners, making it an even better value. Everyone who completes the seminar will also be invited to participate in the Korea Trip.

Korea Trip – Everyone who completes the Master License Seminar will get to go to Korea from July 27- Aug 3rd. Participants will have to pay for their own airfare, but hotel, food, ground transportation and more will be covered. Participants will get to spend 3 days at the Kukkiwon and 3 days at the newly constructed Taekwondowon in Muju. (http://www.tkdwon.kr/eng/)

What’s the Catch? 

At this point, many people may be wondering about the fine print. There are two important restrictions –

  1. The trip to Korea is only for 4th Dan Kukkiwon holders and up.
  2. The event is limited to the first 300 people who sign up.

As of press time on April 3, there are still a few spots open. For more information or to register, please visit www.kukkiwonlicense.com

Lunch for the Homeless

Black Belt Service Project for Yilun Parkhouse-Song

For my service project I organized donations for lunches for homeless people. I also organized a group of people to make sandwiches, pack the lunches, and go downtown to hand the lunches out to the homeless on November 13th, 2016.  The lunches had a ham and cheese sandwich, granola bar, chips and a bottle of water. There were about 30 people who helped. Some only helped pack and make the lunches and some only helped pass out the lunches to the homeless people. We made about 130 lunches for the homeless. I was very surprised when I saw how many homeless people there were along the streets near the Samaritan House. There were easily more than 100 homeless people along the streets. The homeless people were very thankful when we gave them the lunches.  I felt happy that the homeless got some food and some water.

Fall Elementary School League Results

(Aurora, CO) – Students from 15 different schools competed in the Fall Elementary League Championships on November 12th, 2016 at the Korean Academy of Taekwondo. Events contested included forms (memorized patterns of movement), board breaking, grappling (trying to earn points by getting partners into a dominant position or causing them to tap out) and sparring (earning points by kicking and punching opponent’s targets).

The event was popular, with 81 athletes competing in a total of 149 events. This marked an 86% increase in the number of events contested over last year’s championships. The battle for top overall points was intense – with 12 points, this year’s fifth place winner would have earned first last year.

Instructor Paola Perez’s Montessori Del Mundo Team was the clear winner throughout, diversifying their sparring only performance from last year. In fact, their 42 points was more than last year’s champion, Aurora Quest, earned the entire 2015-2016 season (28).

Twin Dragons Tournament Results

12376745_1117904631575662_7927685613278872855_n(Denver, CO) – The Twin Dragons Tournament was held at Metro State University on April 16-17. It seemed fated, but once again it snowed. The forecast caused the addition of a new event, the best school spirit snowman contest. Fortunately, although it snowed for 40+ hours straight at the venue, the snow didn’t stick except during the earliest hours of Sunday morning. Despite the weather, almost all of the 300+ competitors managed to make it and compete successfully. The event also completed the 2015-2016 CO K8 School League Season. 

Saturday featured all of the events besides sparring and grappling, and the level was high across the board, especially in the black belt divisions. In the Men’s Black Belt Forms division, Joshua Sallee (ALL) top top honors followed by Chris Endo (Victory) with John Lynn (Left Foot) and Ian Fleddermann (CU Denver) earning the bronzes. On the Women’s side Angela Olsen (ALL) took first with Summer Cannon (ALL) in second and Emma Hatfield (UNC) in third.

In board breaking, Master RJ Tomas (KAT) won with a mind-boggling routine that included 3 separate boards with spearfingers as well as a 2 board break with one finger. See the video here. Joshua Sallee (ALL) took second while Chris Garcia (ALL) and Sam Waters (ALL) finished third. On the Women’s side Angela Olsen (ALL) took gold. The boys 15-17 breaking had incorrect results. The order should have been Matthew Doyon (ALL) Gold, Janus Tomas (KAT) Silver, Jeremiah Manzanares (ALL) Bronze.

13010825_10204482017810123_3572031381055871719_n

Yes that actually happened.

 

Blaster Pad sparring and Junk Weapons were once again a big hit, with students young and old alike going all out and coming up with creative martial arts uses for all sorts of everyday household objects. The team forms and group forms were amazing, with a special performance by the ALL Snapdragons, a team of women in their 40s and 50s who were amazingly skilled and synchronized.

The new Cloud Chess event featured few competitors but fierce matches, with Theo Sisson (Victory) and Master Laron Younger (LaKai) taking the Jr and Sr divisions respectively. They were unable to play for the Grand Championship, and the event will have to be scheduled for a later time.

Matthew Doyon (ALL) captured gold over Janus Tomas (KAT) by virtue of long combinations and thunderous crowd noise.

Grandmaster Barb Kunkel’s ALL Competition Demo Team continued their domination of the main event, with a poignant and powerful Olympic themed demo. It was the 5th year in a row that they took top honors. The trick kick battle provided some fantastic aerial stunts, including several competitors landing full twisting flips and Master RJ throwing a 540 Gyro. The Trick Kick Battle is one of the most positive events, with competitors cheering loudly for their opponents, crowd noise factored into the judges’ scores, and even an impromptu kindergarten/pre-school division.

Shin’s Academy took home the School Spirit Snowman building award

Sunday featured some great sparring and grappling matches at all levels from young beginners to top black belts. In the Men’s Black Belt Lightweight division, Augustin ‘El Tinito’ Luevano (Luevanos) dominated, bringing home the gold in one of the largest divisions. Brandon Lau (UNC) finished second with Dylan Badiga (Delgados) and Trenton Alberts (Han Lee) taking bronzes.

The Men’s Middleweight Black Belt Division was won by Bruce Mejia (Rock) with Jacob Gonzalez (Gonzalez TKD) earning second and Andrew Lopez (ACT) and Francisco Santos (Gonzalez) rounding out the podium.

The Men’s Heavyweight Division champion was Farhang Mousavizadeh (KAT) who defeated Sam Douglass (KAT). 

Adult women’s black belts had a combined weight division, which was won by Eva ‘Bubbles’ Luevano (Luevanos) with Angela Olsen (ALL) in second and Katelyn Wiegand (UNC) in third

In the adult advanced grappling divisions, Andrew Lopez (Auraria Campus Taekwondo) took gold for lightweight and Sir ‘Reaper’ Salonis (STORM) took it for heavyweight. In the women’s division, Angela Olsen (ALL) earned the top honors.

All in all the tournament was a big success, with numerous compliments and not a single complaint about the organization. Still, there is much that can and will be improved to make it an even smoother experience.

Many students won the Grand Champion ring (11 points) but the MVP of the tournament has to go to Angela Olsen (ALL) who dominated the women’s black belt divisions, winning gold in Forms, Breaking, Demo, and Grappling and silver just in sparring.

Much thanks to all the competitors, coaches, and parents who attended and we look forward to seeing you at the 2017 Lone Wolf Classic.
