Blockchain Definition Explained

What is Blockchain?

Blockchain is basically a new method of storing data.

  • The traditional way: We store everything on a centralized server. All data is gathered in one place to process. If the centralized server is manipulated, all data will be lost, or maybe modified. Hence, the integrity of data is at risk for most of the time.

 

  • With Blockchain: 
    • We store data in a block, which contains data and timestamp (created time). All created blocks obviously are connected, which create a consecutive chain in an order of time. That’s why we call this technology ‘Block-chain’.
    • Not just that, the Blockchain is hosted by multiple computers. Each one is called ‘Node’, which contains a copy of the Blockchain. Every time a new block is created, it need to be verified by more than 51% of the nodes. Only until then, the new block will be recorded.
    • Created blocks cannot be altered. We can only add new blocks to record an alter version of the recorded data. This mean the integrity of data is intact, and we can always trace back to the original version.

What is Smart Contract?

Smart Contract is similar to regular contract, but it is created by Programming language instead of ink & paper.

 

Smart Contract is created and stored on a certain Blockchain, in a block, with a timestamp.

 

Smart Contract can execute automatically by itself, when a certain condition is reached.

 

It’s a trust-less system with a transparent mechanism.

  1. You can check the code in any Smart Contract, and how it operates before filling up the condition by using any Block Explorer.
  2. Once a Smart Contract is created, it cannot be re-written.
  3. No one operates the Smart Contract, but itself.

 

 

What are Tokens?

Blockchain tokens are created from Smart Contract, an advanced feature of Blockchain. This enables users to create assets that transferable. Technically, everything that exists on Blockchain is data.

 

For example:

A creates a type of token Z that pledged to USD as a median of exchange. Token Z is actually recorded by a Smart Contract on Blockchain that verifies its value is always equal to USD. A actually does not create any physical assets, but a Smart Contract that records the existence of token Z, and tracks movement of token Z, or even its ownership.

B accepts token Z and willing to trade some goods, or even fiat for token Z, so that he can use token Z to achieve something else.  Then, they make a trade. In this case value is created from thin air. The good thing is token Z cannot just disappear as everything is recorded on Blockchain in an order of time. It’s a trustless system as any movement is reported by Blockchain. Of course, B can send token Z to anyone he wants regardless of borders, or administration. That’s the strongest point of Token Z.

The example only reflects a part of all advantages of Blockchain Tokens. On TomoChain, there are two most popular standards for tokens: TRC-21 & TRC-721. TRC-21 is used for tokens that serve the purpose of being a median of exchange. TRC-721 is actually used to create NFTs (Non-fungible Tokens) that exist as collectibles.

What is Private Key?

Private Key is basically the password to access your account. In the Blockchain world, you only need a Private Key to access an account, without a need to know other things like the username, or anything at all. Private Key is all you need.

 

This simply means who has the Private Key will be the owner. You cannot modify your Private Key in anyways, as it’s provided by the Blockchain. In case your Private Key is leaked, you have to move everything to another account immediately. The reason is your account is not secured anymore.

What is Staking?

Staking is the process when you lock on an amount of asset to become a validator in a POS network. In return, you will earn the transaction fees that divided within the network. It basically as similar as creating a saving account to earn interest in a bank.

 

What is TomoChain?

TomoChain is basically a distinguished Blockchain that following POS format, instead of POW. This minimizes the transaction fees, mining costs, and transaction time tremendously.

 

 

The native currency of TomoChain is TOMO. Aside from TOMO, we can also find, or create other tokens (in TRC-21 standard), and NFTs (Non-fungible tokens).

 

What is NFT?

NFT stands for Non-fungible Token.

 

Basically, you can create NFT by using Smart Contract that based on Blockchain. It means everything is store on a certain Blockchain. Any Blockchain that provides Smart Contract feature will be able to generate an environment to create NFT.

 

An NFT would normally contain an image with special attributes. The attributes can be anything that text-based, like a passcode, characteristic of an item, a description, etc.

 

An NFT would last forever on a Blockchain with a unique ID. Each NFT is differentiated by its ID. They might contain the same image and attribute, but the ID will be different. Every data is recorded on a block with created time (timestamp). This creates authenticity for each NFT.

 

Pantogram & Panto NFT are created by facilitating Smart Contract feature of Blockchain Technology.

 

Use Cases

Use Cases Explained

Is Blockchain Safe?

Yes, it’s safe. Blockchain operates on a decentralized mechanism, which means everything is stored on multiple servers or computers, instead of one centralized server. That means saving data with Blockchain is much more secured than the traditional way.

 

Sending to the wrong address?

Blockchain is based on the decentralized structure, which means no one has the authority to alter recorded data. It’s totally different from centralized structure where an entity has the full power to manipulate, or to modify the system.

 

Hence, if you accidentally send your asset to the wrong address. There is no way, or no one can reverse what happened. Please be extra careful when sending your asset.

I lost my device!

The good news is your assets are not actually stored in your device. Everything is on Blockchain. It means as long as you still have your private key, you can always get your assets back safe and sound.

 

You can just get a new device, re-install Pantograph and restore your old account with your private key. From then, it’s a good idea to move everything to a new account. Since device is lost, there is a chance somebody might be able to access your old account, so it’s best to use a new account instead.
