Blockchain technology is also gaining attention.By allowing digital information to be distributed but not copied, blockchain technology created the backbone of a new type of internet.

Blockchain Analysis

Blockchain technology can enhance the basic services that are essential in trade finance. At its core, blockchain relies on a decentralised, digitalised and distributed ledger model. By its nature, this is more robust and secure than the proprietary, centralised models which are currently used in the trade ecosystem.
Blockchain technology creates a viable, decentralised record of transactions – the distributed ledger – which allows the substitution of a single master database. It keeps an immutable record of all transactions, back to the originating point of a transaction. This is also known as the provenance, which is essential in trade finance, allowing financial institutions to review all transaction steps and reduce the risk of fraud.
  • Blockchain keeps a record of all data exchanges — this record is referred to as a “ledger” in the cryptocurrency world, and each data exchange is a “transaction“. Every verified transaction is added to the ledger as a “block”
  • It utilizes a distributed system to verify each transaction — a peer-to-peer network of nodes
  • Once signed and verified, the new transaction is added to the blockchain and can not be altered
  • With a set of cryptographic keys, you get a unique identity. Your keys are the Private Key and Public Key, and together they are combined to give you a digital signature. Your public key is how others are able to identify you. Your private key gives you the power to digitally sign and authorize different actions on behalf of this digital identity when used with your public key.
  • In the cryptocurrency world, this represents your wallet address (public key) and your private key is what let’s you authorize transfers, withdrawals, and other actions with your digital property like cryptocurrencies. As an aside, this is why it’s so important to keep your private key safe — anyone who has your private key can use it to access any of your digital assets associated with your public key and do what they want with it!
  • Everytime a transaction occurs, that transaction is signed by whoever is authorizing it. That transaction might be something like “Alice is sending Bob 0.4 BTC”, will include Bob’s address (public key), and will be signed by a digital signature using both Alice’s public key and private key. This gets added to the ledger of that blockchain that Alice sent Bob 0.4 BTC, and will also include a timestamp and a unique ID number. When this transaction occurs, it’s broadcasted to a peer-to-peer network of nodes — basically other digital entities that acknowledge that this transaction has occurred and adds it to the ledger.
  • Each transaction in that ledger will have the same data: a digital signature, a public key, a timestamp, and a unique ID.
For all its complexity, blockchain’s potential as a decentralized form of record-keeping is almost without limit. From greater user privacy and heightened security, to lower processing fees and fewer errors, blockchain technology may very well see applications beyond those outlined above.


Transactions on the blockchain network are approved by a network of thousands or millions of computers. This removes almost all human involvement in the verification process, resulting in less human error and a more accurate record of information. Even if a computer on the network were to make a computational mistake, the error would only be made to one copy of the blockchain. In order for that error to spread to the rest of the blockchain, it would need to be made by at least 51% of the network’s computers — a near impossibility.


Blockchain eliminates the need for third-party verification and, with it, their associated costs. Business owners incur a small fee whenever they accept payments using credit cards, for example, because banks have to process those transactions. Bitcoin, on the other hand, does not have a central authority and has virtually no transaction fees.


Blockchain does not store any of its information in a central location. Instead, the blockchain is copied and spread across a network of computers. Whenever a new block is added to the blockchain, every computer on the network updates its blockchain to reflect the change. By spreading that information across a network, rather than storing it in one central database, blockchain becomes more difficult to tamper with.


blockchain is working 24 hours a day, seven days a week. Transactions can be completed in about ten minutes and can be considered secure after just a few hours. This is particularly useful for cross border trades, which usually take much longer because of time-zone issues and the fact that all parties must confirm payment processing.


Many blockchain networks operate as public databases, meaning that anyone with an internet connection can view a list of the network’s transaction history. Although users can access details about transactions, they cannot access identifying information about the users making those transactions. It is a common misperception that blockchain networks like bitcoin are anonymous, when in fact they are only confidential. That is, when a user makes public transactions, their unique code called a public key is recorded on the blockchain, rather than their personal information. Although a person’s identity is still linked to their blockchain address, this prevents hackers from obtaining a user’s personal information, as can occur when a bank is hacked.


Once a transaction is recorded, its authenticity must be verified by the blockchain network. Thousands or even millions of computers on the blockchain rush to confirm that the details of the purchase are correct. After a computer has validated the transaction, it is added to the blockchain in the form of a block. Each block on the blockchain contains its own unique hash, along with the unique hash of the block before it. When the information on a block is edited in any way, that block’s hash code changes however, the hash code on the block after it would not. This discrepancy makes it extremely difficult for information on the blockchain to be changed without notice.
