Blockchain Basics

Understanding Blockchain Technology and Its Uses

• Blockchain is a distributed database or ledger that maintains a secure and decentralized record of transactions, making data in any industry immutable.

• Blockchains reduce the need for trusted third parties, which can add costs and make mistakes.

• Blockchains consist of programs called scripts that conduct tasks like entering and accessing information and saving and storing it somewhere.

• Transactions follow a specific process, depending on the blockchain they are taking place on, and are confirmed by the network.

• Blockchains allow data to be spread out among several network nodes, which creates redundancy and maintains data fidelity.

• The decentralized nature of the Bitcoin blockchain allows all transactions to be transparently viewed, and each node has its own copy of the chain that gets updated as fresh blocks are confirmed and added.

• Blockchain technology achieves decentralized security and trust by storing data linearly and chronologically, making it impossible to change previous blocks without changing the following ones.

• Banking stands to benefit from integrating blockchain into its business operations, allowing for faster and more secure transactions.

• Blockchain can give those in countries with unstable currencies or financial infrastructures a more stable currency and financial system.

• Healthcare providers can leverage blockchain to store patients' medical records securely and ensure privacy.

• Blockchain can eliminate the need for physical deeds and tracking down physical files in a local recording office, making property ownership more efficient and transparent.

• Smart contracts, which are computer codes built into the blockchain to facilitate contract agreements, have many potential applications, such as in leasing apartments or verifying the authenticity of products.Understanding Blockchain: Pros, Cons, and Applications

• Blockchain is a decentralized form of record-keeping that maintains transparency and reduces the need for third-party verification and associated costs.

• Transactions on the blockchain network are approved by thousands of devices, resulting in less human error and an accurate record of information.

• Blockchain does not store information in a central location, making it more difficult to tamper with and allowing for 24/7 transaction processing.

• Blockchain networks are typically public, meaning anyone can view transaction details, but identifying information about users is not accessible.

• Once a transaction is recorded, its authenticity must be verified by the blockchain network and cannot be altered.

• Blockchain technology can be used for a variety of applications beyond cryptocurrency, including storing medical records and property rights.

• Blockchain is not free and consumes vast amounts of computational power, particularly Bitcoin's proof-of-work system.

• The speed and data efficiency of blockchain can be limiting, but solutions such as sharding and merging between main net and beacon chains are in development.

• While blockchain preserves privacy, it also allows for illegal trading and activity on the dark web, accounting for only 0.24% of all cryptocurrency transactions in 2022.

• Governments could theoretically make cryptocurrencies illegal, but the decentralization of the network makes it difficult to end.

• There are over 23,000 active cryptocurrencies based on blockchain, with several hundred more non-cryptocurrency blockchains.

• Blockchain technology can make business and government operations more accurate, efficient, secure, and cheap, with fewer middlemen, and is expected to see significant growth in the next decades.
