What are the three primary components in a Blockchain?

Therefore, in this post, I will go over the three main components of blockchain technology: the blockchain itself, peer-to-peer networks and consensus mechanisms. Bitcoin would not be able to exist if any one of these components did not exist. Let’s start with the blockchain.

Which tool is used to create configurations?

The tool to generate the configuration transaction is called configtxgen. The artifacts generated in this step are the orderer genesis block, the channel configuration transaction, and one anchor peer transaction for each peer organization. There will also be a configtx.

What is a Blockchain technology?

Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain.

How many blocks are in a Blockchain?

This means that there are 500311 blocks before this one. Since the creation of the Bitcoin blockchain in 2009, 500312 blocks have been created ( at the time of writing obviously ). A block height is not unique. Several blocks can compete for the same position in the case of a fork, like Bitcoin Cash for example.

Can Blockchain be hacked?

It’s decentralized nature and cryptographic algorithm make it immune to attack. In fact, hacking a Blockchain is close to impossible. In a world where cyber security has become a key issue for personal, corporate, and national security, Blockchain is a potentially revolutionary technology.

How is a Blockchain created?

Miners create new blocks on the chain through a process called mining. In a blockchain every block has its own unique nonce and hash, but also references the hash of the previous block in the chain, so mining a block isn’t easy, especially on large chains.
