Expect the Unexpected in Blockchain 2021- Pulsehyip

Blockchain is said to be the most revolutionary innovation that can potentially disrupt every sector. Starting from the financial institutions to basic healthcare organizations blockchain can play a major role. The major benefits include the reduction in settlement time, transaction fees and improvement in liquidity. Gartner, one of the top research and advisory firm has listed blockchain in the top ten strategic technologies in the year 2020. Gartner says that the blockchain has the ability to remodel industries by enabling transparency, trust and facilitating exchange of values across the business.

Also experts predict that 2021 will be the year for entreprise blockchain and it will be a marked time for blockchain to climb out of the trough of disillusionment. Even though the climb will be slower, there may be a steady forward movement.

Compared to 2019 nearly 14% of the entreprise blockchain solutions moved to productions in 2020 which is a 5% increase from 2019. Blockchain projects are very likely to increase in 2021 as many key trends will push the market of permissioned blockchain to the next level. The blockchain techology in 2020 has contributed to the development of more grounded and mature blockchain implementations.

Globally Blockchain technology will grow exponentially

The popularity of Blockchain technology has exploded and increasingly many industries have showed interest to adopt blockchain technology to enhance their businesses. The digital transformation during COVID-19 is very notable especially via the use of blockchain or distributed technology. Because of this, the global blockchain market is expeceted to expand from USD3.0 billion (in the year 2020) to USD 39.7 billion (in the year 2025).

Effect of COVID-19 on Blockchain Technology

Its been predicted that there may be a reorientation of various blockchain projects. This is mainly because 90% of the blockchain are ignoring the key features such as smart contracts, decentralized consensus, tokenization. The practical approach to the new blockchain initiatives can majorly help the daily processes in businesses around the globe. There has also been an increasing amount of institutional participation in blockchain networks.

Acceleration of Digital transformation in Corporates

The businesses at present are now in a critical situation for their survival due to the strain that’s been put upon the businesses due to COVID-19 pandemic. The mere reason triggers the need for corporates to accelerate their digital transformation. Blockchain technology is going to make the most unexpected changes in the ways businesses function in the upcoming years.

Global acceleration of Blockchain projects to Production

Experts have predicted that many blockchain based projects will switch to production stage. This is mainly due to pandemic induced situation and new startup projects that may bring profits in a short span of time. Presently, more than 40% of the corporates has made sure to run atleast one blockchain. And majority of the project will run on private blockchain platforms.

Private Blockchain will Dominate

The Blockchains are now developed and customized based on the corporate business needs and the these blockchains provide more opportunities to the corporates in order to implement blockchain technology for business to business needs with more efficiency and increased security.

Defi and Blockchain Technology

DeFi is now the trending model and it has paves a way for the blockchain to be used in financial services. This type of use case was the main limitation in enterprise blockchain. Defi mainly involves the successful implemention of smart contracts for the financial services.

Currently, there has been an hype about Defi services in various sectors and the initial growth of DeFi even surpassed USD 10 million. It will also speed up during 2021. Also the CeDeFi will come into effect will more financial institutions adopting it, thus bringing together the best of centralized and decentralized systems.

Zero Knowledge Proof with Blockchain

Another important trend that may be seen in 2021 is the launch of zero knowledge proof that are needed to meet the challenges and requirements of preserving the “confidentiality” that holds back various blockchain projects.

The ZKPs allows the companies with various record keeping systems to be in sync on record to record basis without sharing sensitive information. ZKPs has made more progression. Since it provides more security, the corporates are trying to develop more ZApps than DApps.

Central Bank Digital currency Projects

Many central banks around the world will explore and launch their own digital currency. This may get intensified in 2021 that’s mainly because of limited use of cash, digitized economy and use of private currencies like libra.

Banking and Financial sector will dominate the market

When we look into the COVID-19 impacted industries, the financial sector is amongst those. It has faced a tremendous growth in the past years and the present situation has forced them to adapt and meet their client demands with growing digital world. The adoption of Blockchain in Fintech will ease their processes. As a result it may produce contactless transaction.

Conclusion

The Blockchain Technology is growing rapidly and these predicted trend will influence the entreprise blockchain in many ways. There may also be upcoming trends that may intensify the changes in blockchain domain. However, blockchain will transform many industries in various ways. Don’t miss out the opportunity to begin your crypto startup.

5 Blockchain Applications That Have Transformed the World of Technology

The blockchain is the decentralized database of the blocks of information, which gets recorded in the chain format and linked in a secured crypto graphical manner. This technology ensures proper safety of the data due to its secure nature, and it totally changes how people carry out transactions. It also brings about a faster and secure process of validating information needed to establish reliability.

Though blockchain technology came into the market to carry out only digital transactions, it is now used in various industries like supply chain, finance, health care, and many more.

The blockchain technology has made its position in mobile app development as well. Blockchain applications are transparent and accountable. From getting easy access to medical records and buying insurance, you can see blockchain applications everywhere.

Here are some of the areas where you can see the use of blockchain applications and how they have changed various industries.

1. Ripple

Ripple is useful for increasing banking transactions. The implementation of blockchain technology in the financial sector is much more profound than any other sector. Ripple proves this. It is one of the greatest tools to record and complete financial transactions.

It develops a large network despite strict physical boundaries. As there is no such third-party involvement present, the cost of these transactions is lower than usual. At the same time, the network also remains transparent and quite secured.

It is normally seen that financial transactions that happen globally are

error-prone and take a lot of time. In addition to this, when the transaction

fees and exchange rates get added up, the total cost usually gets high.

However, Ripple offers real-time international transactions without spending too much money. It has the network of about 200+ institutions making the process affordable, secure, and fast for all sorts of international transactions.

2. Etherisc

This blockchain application helps in automating flight insurance. Insurance is another area where blockchain is gaining popularity. Through this application, insurers can make smart contracts rather than getting involved in the traditional contracts that are usually complex. Etherisc is the blockchain application that helps customers buy flight insurance. If the flight gets canceled or delayed, they do not have to wait for months to get the payment back. This application ensures an on-time payout.

Skills Needed for A Blockchain Developer in 2021

Blockchain growth is potentially the world’s fastest growing industries today, as businesses look forward to new implementations, systems development and market improvement. They need the services of a Blockchain Developer specialist for all this.

Technology is an ever-advancing thing and Blockchain is the way to go to become an expert in this area and to develop a good career for now and for the future. You need to have power over unique skills to become a blockchain developer.

Let’s address the opportunity to receive a Blockchain developer certification that one can master:

Web Development: Web development is one of the most important elements that the Blockchain developer wants to have the command to reach the profession of Blockchain. Internet architecture concepts such as back-end, front-end, which are commonly used in the development of decentralized applications, need to be commanded.

Data Structures: You have to have comprehensive knowledge of data structures when you begin a Blockchain developer career. In this field, the majority of experts are continuously linked to data structures such as Patricia trees or Merkle trees. The use of various data structures to help create a protected and immutable framework is involved in Blockchain.

Data Architecture: For a Blockchain developer, intense understanding of essential concepts such as hash functions, distributed ledger technology, and cryptography is important. Such ideas should be on the edge of a developer. Blockchain professionals need to know how it operates, how it works and how it is designed around Blockchain.

Learn about Smart Contracts and Solidity: Smart Contracts are concerned about the automation protocols or guidelines used to ensure that no third party is involved in the event of the transaction. Three main components are fundamentally dependent on Smart Contracts: deterministic, terminable and isolation. Solidity is mainly a high-level, statically influenced JavaScript language responsible for writing smart contracts. There are several other languages used for writing smart contracts, such as Vyper, Simplicity, etc.

Experience: Now, in the Blockchain development domain, one must acquire some hands-on experience. Blockchain training is what allows you to bring your theoretical learning into the real world in order to expose you and allow you to become more advanced in technology, software and platforms. You can apply for different internships or training programs to gain the most practical experience. Also, to get valuable insights, you can enter some discussion groups to interact with Blockchain experts.

After all of these, you are advised to go for suitable certification from Blockchain developers such as IBM, CBSA, etc. that would assist you to land many important career opportunities along with providing the learning analysis and validation platforms. The above is the roadmap that would lead you to becoming a good Blockchain developer. Without paying enormous attention, hard work and discipline, it is not easy to become a Blockchain professional. Blockchain developers seem to be taking advantage of ravishing opportunities in view of the growth of Blockchain technology, its growing usage in various industries and the research undertaken by the Blockchain Council to find its scope in the future.

Frequently Asked Questions (F.A.Q.s) & Answers

Q: What's a Blockchain?

A: A blockchain is a distributed database with a list (that is, chain) of records (that is, blocks) linked and secured by digital fingerprints (that is, cryptho hashes). Example from blockchain.rb:

[#<Block:0x1eed2a0
  @timestamp     = 1637-09-15 20:52:38,
  @data          = "Genesis",
  @previous_hash = "0000000000000000000000000000000000000000000000000000000000000000",
  @hash          = "edbd4e11e69bc399a9ccd8faaea44fb27410fe8e3023bb9462450a0a9c4caa1b">,
 #<Block:0x1eec9a0
  @timestamp     = 1637-09-15 21:02:38,
  @data          = "Transaction Data...",
  @previous_hash = "edbd4e11e69bc399a9ccd8faaea44fb27410fe8e3023bb9462450a0a9c4caa1b",
  @hash          = "eb8ecbf6d5870763ae246e37539d82e37052cb32f88bb8c59971f9978e437743">,
 #<Block:0x1eec838
  @timestamp     = 1637-09-15 21:12:38,
  @data          = "Transaction Data......",
  @previous_hash = "eb8ecbf6d5870763ae246e37539d82e37052cb32f88bb8c59971f9978e437743",
  @hash          = "be50017ee4bbcb33844b3dc2b7c4e476d46569b5df5762d14ceba9355f0a85f4">,
  ...

Q: What's a Hash? What's a (One-Way) Crypto(graphic) Hash Digest Checksum?

A: A hash e.g. eb8ecbf6d5870763ae246e37539d82e37052cb32f88bb8c59971f9978e437743 is a small digest checksum calculated with a one-way crypto(graphic) hash digest checksum function e.g. SHA256 (Secure Hash Algorithm 256 Bits) from the data. Example from blockchain.rb:

def calc_hash
  sha = Digest::SHA256.new
  sha.update( @timestamp.to_s + @previous_hash + @data )
  sha.hexdigest   ## returns "eb8ecbf6d5870763ae246e37539d82e37052cb32f88bb8c59971f9978e437743"
end

A blockchain uses

  • the block timestamp (e.g. 1637-09-15 20:52:38) and
  • the hash from the previous block (e.g. edbd4e11e69bc399a9ccd8faaea44fb27410fe8e3023bb9462450a0a9c4caa1b) and finally
  • the block data (e.g. Transaction Data...)

to calculate the new hash digest checksum, that is, the hash e.g. be50017ee4bbcb33844b3dc2b7c4e476d46569b5df5762d14ceba9355f0a85f4.

Q: What's a Merkle Tree?

A: A Merkle tree is a hash tree named after Ralph Merkle who patented the concept in 1979 (the patent expired in 2002). A hash tree is a generalization of hash lists or hash chains where every leaf node (in the tree) is labelled with a data block and every non-leaf node (in the tree) is labelled with the crypto(graphic) hash of the labels of its child nodes. For more see the Merkle tree Wikipedia Article.

Note: By adding crypto(graphic) hash functions you can "merkelize" any data structure.

Q: What's a Merkelized DAG (Directed Acyclic Graph)?

A: It's a blockchain secured by crypto(graphic) hashes that uses a directed acyclic graph data structure (instead of linear "classic" linked list).

Note: Git uses merkelized dag (directed acyclic graph)s for its blockchains.

Q: Is the Git Repo a Blockchain?

A: Yes, every branch in the git repo is a blockchain. The "classic" Satoshi-blockchain is like a git repo with a single master branch (only).

Comments from the reddit ruby posting:

Wait, so a blockchain is just a linked list?

No. A linked list is only required to have a reference to the previous element, a block must have an identifier depending on the previous block's identifier, meaning that you cannot replace a block without recomputing every single block that comes after. In this implementation that happens as the previous digest is input in the calc_hash method.

What about Proof of Work / Waste?

Let's add a proof of work / waste to the blockchain. In the classic blockchain you have to compute a block hash that starts with leading zeros (00). The more leading zeros the harder (more difficult) to compute. Let's keep it easy to compute with two leading zeros (00), that is, 16^2 = 256 possibilites (^1,2). Three leading zeros (000) would be 16^3 = 4_096 possibilites and four zeros (0000) would be 16^4 = 65_536 and so on.

(^1): 16 possibilties because it's a hex or hexadecimal or base 16 number, that is, 0 1 2 3 4 6 7 8 9 a (10) b (11) c (12) d (13) e (14) f (15).

(^2): A random secure hash algorithm needs on average 256 tries (might be lets say 305 tries, for example, because it's NOT a perfect statistic distribution of possibilities).

Example:

def compute_hash_with_proof_of_work( difficulty="00" )
  nonce = 0
  loop do
    hash = calc_hash_with_nonce( nonce )
    if hash.start_with?( difficulty )  
      return [nonce,hash]     ## bingo! proof of work if hash starts with leading zeros (00)
    else
      nonce += 1              ## keep trying (and trying and trying)
    end
  end
end

def calc_hash_with_nonce( nonce=0 )
  sha = Digest::SHA256.new
  sha.update( nonce.to_s + @timestamp.to_s + @previous_hash + @data )
  sha.hexdigest
end

(Source: blockchain_with_proof_of_work.rb)

Let's rerun the sample with the proof of work machinery added. Now the sample will pretty print (pp) something like:

[#<Block:0x1e204f0

See the difference? All hashes now start with leading zeros (00) and the nonce is the random "lucky number" that makes it happen. That's the magic behind the proof of work.

A period in the Dutch Golden Age during which contract prices for bulbs of the recently introduced tulip reached extraordinarily high levels and then dramatically collapsed in February 1637.

Quotes - Blockchains are the next Internets / Tulips

People who compare digital tokens to tulips are essentially saying digital tokens are a bubble backed by nothing but pure hype and speculation.

What they fail to understand is that tulips come from dirt, not a blockchain.

And as we all know, blockchain is possibly the best technological innovation since the internet. It will have a tremendous impact on global business and society in general. -- TulipToken

Certified Blockchain Expert™ | Blockchain Certification | Blockchain Council

A multitude of use cases around the numerous industrial segments are now contained in the blockchain technology that once began as the underlying system for Bitcoin trading. One of the main impacts on the financial sector has been felt. Blockchain technology has been publicly adopted by businesses like JP Morgan. The financial sector is suffering from data protection problems, faster transactions, transparency and other bottlenecks that hamper the growth of businesses that rely on monetary transactions from banks and NBFCs. Blockchain could therefore be a possible solution here. Banks and financial sectors can easily solve the disadvantages that hold back the banks’ smooth functioning with Blockchain’s involvement.

Some of the biggest developments we have seen in the Blockchain sector are the development of Blockchain platforms such as Hyperledger Sawtooth, Hyperledger Fabric, Corda, etc This approved Blockchain not only ensures that the system operates efficiently, but also ensures that transactions take place at a faster rate. It actually helps the banking system work much better and in a more effective way.

How the financial sector is impacted by Blockchain:

1. Providing a safe platform-
The need for a secured platform is one of the greatest challenges facing most banking and financial institutions. As most of the transactions and other work have now been digitised, most banks and other allied companies are looking for a stable platform that is free of any mistakes or defects. In addition, there is also a high rise in the need for a network that can efficiently combat data breach problems, and so we have Blockchain. By time-stamping all information or data on it this DLT platform works. This guarantees full security. And with the introduction of approved Blockchain networks, the security feature is even more assured.

2. No third party- Time lag and paperwork are two weaknesses of the financial sector that appear to hold up the processes and ultimately influence the company’s efficiency as well. We can solve these problems with the assistance of Blockchain technology and thus ensure quicker transactions. Blockchain technology operates on peer-to-peer transactions, ensuring that for authentication and approval, there is no need to rely on a third party, which speeds up the transaction process.

3. Tracking and tracing- For banking firms, these features can be highly beneficial. Banks invest a large amount of money on authentication and verification, amid all the efforts of false identity cases, and fraud reports are growing, we can easily put an end to it with Blockchain.
