What is the difference between Proof of Work (⛏ PoW) and Proof of Stake (💰 PoS)? 🤓

As you may have heard, the Proof of Work algorithm causes high power consumption all over the world. Nevertheless, it is still used for running blockchains:
⛏ Proof of Work was originally developed to secure the Bitcoin blockchain, because it could achieve a consensus among the nodes on the network. It works by requiring all nodes to solve a cryptographic puzzle in order to create new blocks within the blockchain. Those who try to solve the puzzle are called miners. And the first miner to find the solution gets the miner reward.
⛏ However, this procedure has led to many people building bigger and bigger mining farms to increase their chances of finding the solution and getting the reward. So, in addition to the extreme energy consumption of the Proof of Work, this algorithm causes an unfair “distribution” of the rewards – people with more money and resources have a higher chance of solving the puzzle.
⛏ Moreover, these people often join so-called mining pools in order to bundle their capacities, thus increasing their chances of finding the solution. The rewards are shared between all the people within the pool. This has led to the system becoming increasingly more centralized rather than decentralized.

To stop this, a new algorithm has been developed: Proof of Stake.
💰 Proof of Stake doesn’t have miners, but validators. To create a new block, these validators don’t mine; what they do in the Proof of Stake algorithm instead is referred to as minting, or forging.
💰 Furthermore, the algorithm does not randomly select the validator to validate transactions or a new block. A node has to deposit a certain amount of coins into the network as stake. The higher this amount, the higher the chances to be chosen as validator.
💰 If a node is chosen to mint a new block, it has to check if all transactions within this block are indeed valid. If they are, the node can add the block to the blockchain. As an incentive, the node receives a reward, consisting of the fees associated with the transactions inside the new block. These fees are transferred to the validator after a certain period of time.
💰 How can we trust these validators? Validators really try not to make any mistakes while checking the correctness of the transactions, because if they do and, for example, one of the transactions they have approved turns out to be fraudulent or simply not valid, they will lose part of their stake as penalty. So this is the financial motivation behind this algorithm.
💰 Although Proof of Stake is not the perfect alternative for Proof of Work, this algorithm has significant advantages: The entire system requires less energy for minting new blocks, and more people are motivated to become validators. Consequently, the system is more decentralized and more secure than the Proof of Work algorithm.

Do you know when smart contracts first came about? 🤓 Already back in the 1990s!😲 Since then, blockchain technology has evolved impressively – and smart contracts can now be programmed in any language that can be integrated into any blockchain environment. They can be used for nearly every contract-based matter.

Smart contracts work basically just like a vending machine: someone inserts the required amount of money and the machine delivers the goods – so, they could be described as “self-executing”, as having a built-in “execution guarantee”.

However, like any other technology, smart contracts also have their weaknesses - and this is exactly where our experienced Zentatec expert developers with their specific blockchain know-how come in! 🚀 For example, Zentatec features the so-called oracles that allow smart contracts to access information even outside the blockchain.

As of late, NFTs have increasingly garnered interest and gained popularity, especially since the recent sale of digital sections of Austrian artist Gustav Klimt´s famous painting “The Kiss”. 💋 The digital copy was segmented into 10,000 individual NFT parts for this purpose.

But how did NFTs come about and how long have they been on the market? 👀
The picture shows a brief history of their development.

Owning coins is one thing. Protecting them from theft is quite another...
The coins in your possession are, of course, stored directly on the blockchain and not within your wallet. However, the wallet plays an important role: IT CONTAINS THE PRIVATE KEY TO YOUR COINS. 🔑

👀 Therefore, utmost caution is required when storing your private key - if an unauthorized person gets hold of it, you may suffer significant damage to your assets! 😱

So be careful and remember:
✔ Your private key is the access to your coins. Whoever owns it, owns your assets.
✔ Keep your private key safe and protect it from theft.
✔ Do not carelessly tell anyone where your private key is.

We recommend creating encrypted backup copies of your private key. Yet even unencrypted ones can be useful, even if it's just a handwritten note on a piece of paper in some drawer: If the originally stored private key gets lost, you can still access and manage your assets with your backup copy. 😎

We have already described the function of wallets in blockchain technology in one of our previous posts. 🚀 And now the time has come to show you how our hardware hub prevents unauthorized access to your crypto assets!

The hardware hub is a special hardware wallet that stores the access keys to your assets offline. This has the great advantage of making it impossible to steal your private key with which to access your cryptocurrencies lying on the blockchain. There are other wallets on the market as well, the so-called “custodial wallets”, that manage your private keys.

But what is the difference between custodial wallets and our hardware wallet?
✔ Since the custodial wallets manage your private keys, these keys are not completely in your hands, making them vulnerable. This is why we strived to develop a secure way of key storage: With the hardware hub, you are the only person to have access to your crypto assets.
✔And there is even more to the hub than being just a hardware “safe”: It is also a portal for your digital investments as well as a mining node that contributes to making the blockchain work.

Our innovative team is currently working on the further development of the hardware wallet - stay tuned, there is much more to come! 🤓🚀

develops wallets associated with blockchain technology - but what are these wallets for? 🧧

A wallet is your gateway to the crypto world: In principle, it is a software that makes it possible to send and receive digital currencies. Being kind of a virtual purse, a wallet securely stores your private key 🔑 that gives you access to your crypto assets. Be it hardware wallets, which work offline, or mobile apps, which work online: there are many different types of wallets. The mobile apps, for example, make dealing with cryptocurrencies as easy as shopping online with a credit card.
❗But be careful: online wallets are vulnerable to hacking attacks❗

Unlike a regular purse, your wallet does not contain your assets directly - they are embedded in the blockchain itself. So the purpose of a wallet is to generate and store the private access key to your assets. This key is proof that you are the owner of the digital assets and only with this key can transactions be carried out. Therefore, it is crucial to use a secure storage method so that hackers don't have a chance.

Zentatec wants your assets to be protected from unauthorized access attempts, which is why we decided to develop hardware wallets that store the private key to your assets offline. This means that the wallet and your assets are in your hands only.

Wait for more details about this special wallet in our next post!👀
