Transparency: Transaction are verified by the network. The network verifies that the information are trusted and true and are then saved on the blockchain. This network of computer get incentives to operate in a fair and honest manner.

Security: The blockchain is based on math. All transactions are verified and it’s impossible to make changes to it. This is why it is impossible to alter informations and to be hacked.

Improved traceability: Transactions are saved on the blockchain and can be traced at anytime by anyone.

Increased efficiency and speed: The blockchain has no need for middle man organisations to operate making transactions a lot faster.

Reduced cost: Transactions are verified by the network therefore there is again no need for middle man to be included making it cheaper.

  1. Transparency:
    Blockchain transparency gives trustability, as no data can be changed or deleted by anyone.
    It’s a public ledger, so everyone can see it.

  2. Security:
    Security is a very important benefit of using blockchain, as each new transaction it is encrypted
    and linked with the previous one and it has to be confirmed by all. You don’t need to trust
    anymore to 3rd parties. We trust in protocols!

  3. Improved traceability:
    The importance of traceability is when you really want to know truth about were the goods come
    from. Using blockchain gives you the truth about it, as it is all chained from the beggining and it
    cannot be modified.

  4. Increased efficiency and speed:
    As it is decentralized , blockchain takes out the need of having a midle men to do a transaction
    and that make faster the transaction in the blockchain.

  5. Reduced cost:
    As it is a technology, is no needed to much cost.

Explain with your own words, why these are the benefits of using a blockchain.

Transparency: Anyone can see what happens in blockchain.

Security: You don\t have to trust any third parties, only trust math and protocol. There is also not possible to erase any data from the blockchain that gives high security.

Improved traceability: Everything that happens in blockchain is visible to anyone so you can trace what every you like from the blockchain.

Increased efficiency and speed: There is no middleman needed because blockchain is decentralized system which makes it very fast system

Reduced cost: With this kind of decentralized technology it does require for high costs.

Transparency:
Anyone can verify the ledger and track where the products/money comes from.
Security:
The ledge can’t be altered you can only add on top of it make it hard to hack
Improved traceability:
Like with transparency, since you can check the ledges and where things come from you have a clear traceable path.
Increased efficiency and speed:
Having a single ledge and a P2P connection makes the transactions efficient with no middle man that can alter the transaction
Reduced cost:
There is no need for middle man, plus all the transactions are saved on the ledge.

Hashing

  1. Secure Hash Algorithm (SHA) SHA-256

  2. It can only be solved to find the ultimate hash output, they cannot be reversed to calculate the initial raw data. The one-way mechanism is guaranteed through intricate mathematical equations which do not allow the reversal of a new hash. Bitcoin hash is only solved in a linear, unidirectional manner.

You posted your homework in the wrong thread. :slight_smile:

You as well, is there an issue with the links in the academy? They usually redirect to the correct thread.

Transparency: 1. Blockchain is a public ledger
2. In blockchain before a data gets added to the blockchain it has to be agreed on collectively by consensus.

Security: Database is spread out on many computers and the system is secured by mining and nodes.

Improved traceability: You can track the origin of the product, way and etc. and verify every step trough the public ledger

Increased efficiency and speed: High availability; There is no middleman; The transactions are p2p.

Reduced cost: There is no third party, middleman or bureaucracy (e.g. audits can be done online). The transaction fees are not pegged to the amount, e.g. 300mil for a few dollars. It’s reduce the transaction time.

Transparency: Blockchain’s transaction ledger is available to the public.
Security: All transactions are verified collectively by the members of the network. The transaction cannot be retrieved once it is verified and data cannot be removed.
Improved traceability: The data can be checked accurately.
Increased efficiency and speed: Transactions are easily accessible.
Reduced cost: Blockchain is decentralised hence there is no middlemen needed.

Transparency is a benefit of using blockchain because the ledger is available for everyone to see; all transactions are recorded and can be traced back to source or destination. This makes users accountable for their transactions and adds consensus to the network.

Security within blockchain is proven from the way blocks & chains are formed. The chaining of blocks via combining new and previous transaction data creates an encrypted and impossible to hack data that users can trust and verify, thus making transactions between entities trustless.

As mentioned briefly, transactions are transparent and can be traced from source to destination, thus goods can be traced and authenticated.

Eliminating third parties in transactions provides for faster transactions speeds using blockchain and digital currencies that are globally traded and decentralized.

Integrating blockchain technologies within companies and the global financial infrastructures can cut down on cost through improved auditing, secure digital contracts, and extremely low transaction fees which closes transactions faster.

  1. Transparency: It forces integrity for the business.
  2. Security: All information has to be verified by all the computers in the blockchain network before its added. It is not possible to change or remove information in the blockchain which makes it much more secure regarding hacker attacks or fraud.
  3. Improved traceability: It provides provenance to any business where the authenticity of the product is important.
  4. Increased efficiency and speed: There is no need for a third party to verify the information as the network works altogether making it quicker and more efficient.
  5. Reduced cost: As there is no need for third parties, just the network verify the information. It can save a lot of money for the fees when transactions are made around the globe.

The benefits of using a blockchain:

Transparency: the ledger that records all transactions is available for anyone to view. For businesses, it means that customers and other organisations in the supply chain can check to make sure that the business in question is being honest.

Security: the protocol inherent within blockchains mean that transactions can be added but cannot be removed or reversed. It is also decentralised, which means that users are not forced to trust a single institution that is storing their information and data.

Improved traceability: every transaction is saved onto the blockchain, leaving an audit trail. Because of the immutability of the network, those attempting to trace specific assets or transactions can be sure that what they are looking at is true.

Increased efficiency and speed: the removal of centralised authorities renders the need for intermediaries superfluous. Financial institutions, insurance companies, and numerous other industries that rely on agents would no longer be required in the same way they are now, increasing speed but also lowering costs. Additionally, high availability - inherent within blockchains through mining - means that the network will never go down.

Reduced cost: as mentioned above, the removal of intermediaries will lower the cost of transactions. Additionally, the transparent nature of the technology will allow users to self-audit, rather than relying on organisations.

These are the benefits of using blockchain

Transparency:
Blockchains ledger is transparent and immutable and requires a consensus from a number of nodes before the transaction is confirmed. Once the transaction is confirmed anyone can view the transaction which promotes accountability and integrity from the parties involved in the transaction.

Security:
Blockchain requires a consensus from a large number of nodes before it is confirmed and added to the ledger of the blockchain. It becomes extremely secure due to the fact that any new transactions are linked to previous transactions on its ledger, via a complex mathematical mechanism. These transactions are verifiable and immutable. With the speed in which new transactions are added to the ledger, and distributed across many nodes on the network, it makes it near impossible to tamper with.

Improved traceability:
Every transaction is recorded on the blockchain and therefore possible to audit. You can trace back to the origin of the exchange of goods (transaction) and see where it originated from. This could help with ownership, authenticity and security of the goods exchanged.

Increased efficiency and speed:
Eliminating the need for a third party, transactions can be processed faster and more efficiently. As the ledger is transparent and accessible to everyone, information and verification can be attained and confirmed by any party, instantaneously.

Reduced cost:
As blockchain works by consensus of nodes on a network you eliminate the need for a third party or middleman, hence making the process of a transaction less costly and more efficient

Explain with your own words, why these are the benefits of using a blockchain.

Transparency:
Thanks to transparency offered by blockchain technology each transaction is visible so this lead to unprecedented layer of accountability and can make real time audit in financial systems and business.

Security:
Since each block need to be confirmed by miners, and they use energy for keep the network secure because they are incentivised to play with the rules, it result impossible (if there are a lot of miners) that the blockchain is altered once formed. So it lead

Improved traceability:
Each transaction/movement that is added to the blockchain can be instantly seen from where it comes from. This is incredible powerful in supply chain traceability because you can make audit in real time.

Increased efficiency and speed:
Blockchain technology lead to more efficiency and improved transaction speed because there is no middle man but it is P2P transaction.

Reduced cost:
No middle man, means also less fees to pay, moreover, because you can program some kind of operation regarding to what is happening on the blockchain, this lead to more automation in the real word and so less operational cost for business.

Transparency:

The public addresses are public and anyone can see the transactions, this is not the case in today’s business world be it in bank accounts or insurance transactions or supply chain monitoring. By being public the blockchain adds a completely new layer of transparency that was not possible with out the blockchain. all the participants have access to the same information/documentation

Security: blockchain are highly secure, historical data verify the authenticity of assets. The blocks are “chained” and no previous or predated dat can be changed. each new transaction is encrypted and linked to the previous transaction.

Improved traceability:

In blockchain one can trace back where an asstet or exchnagde item comes originally from. this will prove highly valuable in supply chain data management system in the fields of medicine, foods and many other areas

Increased efficiency and speed:

The blockchain does not need a third party to verify a transaction it therefore provides higher efficiency in transacting and speed by cutting out the middleman. The automation process also reduces the chances of human error.

Reduced cost:
The blockchain can replace or is not in need of many bureaucratic, time demanding and high cost tasks such as accounting if used correctly by not needing to mathc the invoice to the transaction for example. Also by removing third party brokers all together like a bank or auditing firm.

  1. Everyone can see what is the source off the money, information, supply chain, etc…
    Which gives big benefits for the customer.
  2. Because the system is decentralized it is far more difficult to harm it.
  3. Because of the blockchain trancparency you can trace every information down to the begining
    which makes the system more fair.
  4. Everything is automated and all the transactions are non reversable and also there is
    no third party involved which makes the system faster and more efficient.
  5. The costs are lower because there is no third party needed and everything is automated.

  1. Blochains public ledger holds everyone accountable by making everything in plain sight of the public. This automatically compels everyone to act in their and the companies best interest.

  2. Blockchain is extremely secure due to group consensus of each transaction through mining and verifying the last block and the next block. Incentives create a multitude of miners which in turn strengthens the security of the system.

  3. The blockchain produces an unalterable record of all transactions making tracing the history of each transaction very easy by just following the chain back to its origination.

  4. Blockchain increases efficiency by eliminating many middle men that are needed in traditional systems due to relying on trust. Eliminating the need for trust eliminates the need of audits and monitoring. This in turn also speeds up many processes by eliminating steps that are unneeded in a “trust less system”.

  5. Same as above, blockchain reduces cost by reducing middlemen and the cost associated with them through the use of smart contracts.
