Understanding the bitcoin blockchain

Bitcoin’s blockchain technology creates a decentralized, viable record of all transactions or a distributed ledger.

You’ve most likely heard or read that Bitcoin is a big deal. Maybe you also know that blockchain is the underlying technology for this cryptocurrency. But what is Bitcoin’s blockchain? What makes the Bitcoin blockchain so essential?

Blockchain presents a technology that can improve essential services in trade and finance. At its core, this technology depends on a digital, distributed, and decentralized ledger model.

And these are the traits that make blockchain a secure and robust technology than centralized, proprietary models that the conventional trade ecosystem uses.

Bitcoin’s blockchain technology creates a decentralized, viable record of all transactions or a distributed ledger. And this ledger makes the substitution of every master database possible. At the same time, this ledger keeps all transaction records immutable and similar to the original transaction.

Also called provenance, this attribute is crucial in trade finance because it enables institutions to review the transaction steps, reducing fraud risk.

Blockchain’s application can also facilitate establishing and proving identity better than the way current systems do. This technology simplifies direct trade assets’ transfer while increasing their provenance’s confidence.

Entities achieve this by providing non-forgeable, unique identities for assets and inviolable ownership records. And this leads to a chance for institutions to offer more financial services based on physical goods’ trade.

Blockchain is Not Blockchain

Most people think about Bitcoin when people mention blockchain. But blockchain and Bitcoin are different things. Blockchain is Bitcoin’s underlying technology.

Satoshi Nakamoto, a mysterious entity, introduced Bitcoin as an unregulated, decentralized, digital currency in 2008.

The blockchain serves as the ledger solution for facilitating the secure recording of transactions that people complete with this digital currency. That’s because the system does not involve a government or bank monitoring the transactions.

Therefore, Bitcoin became the first product to leverage blockchain technology. People confuse Bitcoin and blockchain since both concepts emerged almost simultaneously.

Blockchain’s Role in the Bitcoin Network

As hinted, blockchain creates a public ledger that lists all Bitcoin transactions. It also provides a way for miners to verify Bitcoin transactions.

Every miner receives the same information because every participant gets the duplicate blockchain copy with this technology. Additionally, people can use the blockchain to trace all Bitcoins from the initial owner or miner.

It’s worth noting that the blockchain records every Bitcoin transaction. Ti also maintains a link to specific addresses and does not personally-identifying email or name. Consequently, Bitcoin remains pseudonymous.

The purpose of the blockchain is to facilitate the recording and distribution of digital information to all participants in the Bitcoin network.

However, nobody can edit the information once recorded in the blockchain. Bitcoin users call this permanence immutability a vital feature in the blockchain data architecture.

Although people can use a blockchain to store varying amounts of data points, like voting, product inventories, home deeds, and state identification, Bitcoin uses it to record payment ledgers transparently.

Each Bitcoin node has maintained a record of data in the blockchain since inception. That means every node has the entire history of every Bitcoin transaction. And if a single node has a mistake in the data, it can refer to thousands of the nodes to correct the error.

Information in the Bitcoin Blockchain

Bitcoin’s blockchain has information about different cryptocurrency blocks arranged chronologically. This information can be:

  • Timestamp information: This includes the date and time of the block’s creation.
  • Difficulty level: This denotes the problem solved and its difficulty level
  • Nonce: This is the number the miners have to solve

Whether you receive Bitcoins from another person or purchase them on a platform like, the blockchain will store this information.

Nevertheless, the ledger won’t keep information that a person can quickly use to identify you as a person. And this makes blockchain anonymous than a conventional bank statement.
