Intoduction To Blockchain Technology

Blockchain exchange and transfer occur by means of a shared distributed ledger, which records all the details of every transaction that occurred among the network participants without involving any trusted centralized party for blockchain development. Each copy of the ledger occupies in synchronization with all the involved parties, thus reducing the risk of a single point of failure.

What is the Blockchain and Why is it So Important?

Bitcoin works on Public Key Infrastructure (PKI) in the blockchain for authenticating users and controlling all the access. For source authentication and identification, each transaction is digitally signed by the owner with a separate key.

To keep a track of all transactions occurring simultaneously, multiple transactions are grouped together in a structure called ‘block’ uniquely identified by its separate hash and timestamps. Validation of each transaction and the block, among potentially distrusted users, is done using an agreement mechanism, which means the state of the shared ledger is updated by the accord of the majority of nodes.

This updating in the case of bitcoin employs the proof-of-work consensus algorithm, whereby miners attempt to find a special value to achieve the block’s hash, less than a target value, which is usually set to avoid any dispute and establish trust.

This target value is set in such a way that miners compete to find a nonce in around 10 minutes, hence the block generation time is 10 minutes.

This process by which nodes perform accurate computations, thus giving their resources to find the nonce is called mining and the nodes doing so are called miners. Through this mining, nodes compute the proof-of-work which is a form of achieving agreement among the distrusted modes.

How Is It Possible For Printing 3D Organs?


Have you ever wondered if it would be possible to ‘print,’ human organs for medical use? The recent developments in the medical tech sphere suggest that this may become a reality sooner than we think.

What is the process?

3D organ printing, otherwise known as bioprinting, enables cellular structures to be fabricated using bio-inks that are laced with stem cells. A biomaterial is deposited layer by layer to make tissue, skin, and sometimes even an organ! 

Making high-quality 3D model printed parts suitable for transplantation would result in a long-term solution to help understand certain diseases better as well as deal with a lack of organ donors. Below are some examples of the main bioprinting projects, including some 3D-printed organs!


A 3D Printed Heart

In April 2019 a team of researchers in Israel was able to print a small 3D heart the size of a cherry. The heart possessed cells, blood vessels, chambers, and ventricles, resulting in a first for the industry.

 To reduce the chance of rejection when implanted the researchers used the patient’s fat tissue to develop a hydrogel. Although the heart is about the same size as a rabbit’s, it is a step in the right direction.

3D Printing An Ear

The Queensland University of Technology helped Maia Van Mulligan regain her hearing by using 3D printing to make her a new ear. They used her cartilage cells in order to make the ear so that there was little risk of rejection when installed. They state the ear is fully functional and will allow Maia to hear again, suprisingly this type of printing is less expensive than current alternatives.


Why Consider Mixed Martial Art Gloves?

all Mixed Martial Arts make it a point to make the fighters wear MMA gloves. These gloves function in two ways: they protect the fists of the fighter from being damaged or injured and they also make it possible for the fighter to deal a destructive blow.

MMA gloves are designed with an open palm and open fingers. This allows so much freedom of movement for the hands. There are four types of MMA gloves according to purpose: sparring, bag, fight, and hybrid gloves. You canĀ  “buy your new pair of boxing gloves” (which is known as “Koop uw nieuwe paar bokshandschoenen” in Dutch online).


Sparring gloves, also known as training or practice gloves, are used in practice bouts and they can be divided in two types: the ones that have the traditional look with individual finger slots whereas the others include a padded striking area with finger loops.

The choice of gloves to spar or train with will depend on what the fighter wants or is most comfortable with. MMA gloves have padding, but none more so than the sparring gloves.

Bag gloves are most handy since they are specially created to minimize the impact of strikes and hits. They are more densely padded and usually include a grip bar and increased wrist support.

As they are designed for bag hitting it is inadvisable to use them in fighting or sparring, as they can cause greater injuries to both the opponent and fighter alike.

Signs That You Need Emergency Tree Service

It can be difficult to decide if emergency tree service is necessary. It can be difficult to tell what level of leaning is normal and how to identify broken branches from the leaves. These are some signs that you need an emergency tree removal service.


An arborist should inspect any type of new lean, especially if it is located over a path or structure. An arborist should be able to determine if a tree has a 15% vertical lean.


Call an arborist immediately if you notice any root decay. Strong winds can cause serious damage to the root system, which is the support structure for your tree.

Although it may not be the case every time, mushrooms growing at your tree's base could indicate root disease or internal rot. This should be evaluated by an arborist because the roots are, as mentioned, your tree's support system.


You might not expect the space between power lines and trees to be so large. In wet weather, electricity can reach up to ten feet between trees and power lines. This can cause damage or power outages. These trees should not be cut or pruned by you. To ensure safety, arborists are trained extensively.


Large dead branches must be removed immediately. Strong winds could bring them down onto property or people.

There has been a huge increase in people interested in organic and natural beauty products. Several major companies are releasing paraben-free hair, skin, and cosmetic products. Many reputable studies have demonstrated the negative effect of paraben and other chemicals in our bodies. 

In addition to hair care products, it is advisable to eliminate parabens from other sources as well. They are contained in most personal care products. You will need to start reading labels on cosmetic and skincare products as well.

The more products containing paraben that you use, the greater the effect on the body. For this reason, removing paraben from all beauty products is the best option. 

However, as we wait for companies to change their ingredients we should be informed and reduce or try to eliminate using products containing parabens.
