Blockchain technology is changing industries with its revolutionary distributed ledger technology. Enterprises across the spectrum are exploring methods to make use of blockchain to challenge traditional business models. This guide will cover everything you need to develop blockchain-based solutions.
## An Introduction to Blockchain
Blockchain is a decentralized public ledger that is decentralized and open to all that tracks transactions on an online peer-to-peer system. It's comprised of immutable blocks of cryptographically verified transactions. Each block has a timestamp and a link to the prior block, creating an irreversible chain.
## Key Properties of Blockchain
Decentralization The network is not controlled by a central authority. Network. The consensus of participants verifies the transaction.
Transparency The ledger is accessible to everyone on the network, which increases the level of trust.
Immutability Once the transaction has been recorded, it can't be changed retroactively.
Provenance Participants can follow the entire history of an asset by time stamps.
Security Hashing, cryptography, and digital signatures protect the network. Consensus mechanisms are used to validate transactions.
## Why Use Blockchain?
Reduce costs for transactions through the disintermediation process
Accelerate settlement of transfer and payment
Improve transparency and the ability to audit
Increase security and decrease the risk of
Discover new revenue and business models, as well as opportunities
## Types of Blockchains
Public Anyone can join without authorization. Bitcoin can be a good example.
Private Access is restricted to authorized users only. It is useful for enterprise solutions.
Hybrid Combines public and private blockchain functions. Participants are granted permissions based on their preferences.
Consortium Managed by a consortium of firms or organizations. E.g., R3 consortium.
## Choosing a Blockchain Platform
Things to take into consideration when selecting the right blockchain platform
* Consensus mechanism
* Scalability
* Interoperability and compatibility with existing systems
* Support for programming languages
* Developer Community and assistance
* Model of licensing
Blockchain platforms that are popular:
* Ethereum is used to create smart contracts
* Hyperledger Fabric - To private enterprise blockchains
* Corda for industries that are regulated, such as finance
* Stellar - For payment systems
* EOS - Supports commercial-scale Apps
## How Blockchain Transactions Work
1. The transaction request is broadcast to a peer-to-peer system
2. Network nodes confirm the transaction on consensus rules
3. Validated transactions are combined with other transactions to form an entirely new block
4. This new block will be added to the current blockchain
5. The transaction is completed once confirmation from the network
## Developing a Blockchain Solution
Take these steps to develop the blockchain-based solution you want to use:
### 1. Identify Use Case
Blockchain should only be used to use it for legitimate purposes like transaction tracking and immutable data, transparency processes, etc.
### 2. Choose a Consensus Mechanism
Proof of Work, Proof of Stake, and various other consensus models have multiple advantages and disadvantages.
### 3. Select a Platform
Evaluation of factors such as security, performance, and community support. To choose the best blockchain platform.
### 4. Design Technical Architecture
The design of the network topology interfaces, components infrastructure, and so on. Necessary to implement the solution.
### 5. Develop Smart Contracts
Implementing business rules, logic, and other processes that regulate blockchain transactions.
### 6. Create Nodes
Set up blockchain nodes on networks, such as peer or cloud servers.
### 7. Develop Client Access Layers
Making mobile or web-based apps that allow businesses to interact with blockchain.
### 8. Test, Debug, and Deploy
Conducting thorough testing on local as well as distributed networks. Fix issues before mainnet deployment.
### 9. Plan for Upgrades and Evolution
Accountability for future upgrades, such as improving consensus rules, adding new features, etc.
## Learning Blockchain Programming
### Languages
Solidity and Vyper for Ethereum. Go and JavaScript for Hyperledger Fabric. Java for connecting to different blockchains.
### Development Frameworks
Truffle, Embark, and OpenZeppelin for Ethereum. Hyperledger Composer for Fabric.
### Concepts to Learn
The Cryptography and Distributed Systems Networking, Consensus algorithms, Hashing Merkle trees
### Resources
Official documentation for developers of blockchain platforms forums, online courses, group mentorship, and blockchain developer communities.
