Blockchain Technology: What it is & how it works

What is a Blockchain Protocol

Being able to continuously update and record important records and statistics (i.e. medical journals, government statistics) could offer the ability to ensure statistics are public, easily accessible, auditable and at the same time secure and un-editable. This has many potential benefits, one of which being that a person does not need to rely a on a third party to provide safe keeping of important records. A cryptocurrency is basically a currency which, rather than being issued and controlled by a central bank, such as US dollars or British pounds, uses an encrypted, mathematical blockchain model, as described above, to track exchange of value and ownership. Since then, thousands of other cryptocurrencies based on the same principle have emerged. It also contains a timestamp to record when the information in that block was created or edited. Finally, it contains the data itself – which is whatever the blockchain is being used to record.

What is the difference between blockchain and blockchain protocol?

In short, a blockchain network is the blockchain ledger plus everyone contributing to that ledger; a blockchain protocol is the rules that govern the network. These two terms may seem to be used interchangeably, but as a rule they should not be.

Moving the e-commerce database to a blockchain will probably be the lesser task. The business is likely to bear the cost of setting up and running the blockchain 2.0 application and to unilaterally draft the terms and conditions of the smart contracts. It should be obvious that smart contract terms with groups of users that are protected by legislation have to comply with minimum rights and prohibitions. The legal position of a consumer, a wage earner, a minor or a tenant cannot be worse under a smart contract than under traditional contracts. If this is the case, courts will invalidate a smart contract that fails to comply, regardless of automation and self-enforcement. The original Bitcoin code has been released under an open source licence and all blockchain 2.0 applications have also been open source.

The pair wanted to create a system where a document’s timestamps (the digital record of how it’s changed over time) could not be tampered with. Inefficiencies in the current business environment often arise due to duplication. For example, in loan documentation or bond trading, multiple parties track documentation, ownership and trading. This type of duplicated effort could be reduced by a Blockchain solution which inherently requires all versions of the database to synchronised. Cryptocurrencies like Bitcoin get all the attention (and notoriety), but it is the underlying Blockchain technology that will revolutionise global business.

If someone tries to alter data, all participants will be alerted and will know who make the attempt. Digital identity – As blockchains are almost totally tamper proof and secure, digital identities stored on a blockchain can protect individuals against any form of identity theft, granting them greater control over their identity. The miner that solves a block is allowed to include a transaction in his block and receives a block reward for doing so, most commonly in the respective cryptocurrency they are validating the transactions of. Anyone can become a validator and support the blockchain, the only requirement is to have access to the internet.

If solved, crypto experts think, it could facilitate a seamless transition from Web2 to Web3 and have added benefits. They suggest a TCP/IP-like standardized communication system between blockchains, as it can address interoperability. For example, it’s been reported that the power usage of the network used to track and verify Bitcoin transactions was around 30 terrawatts last year. By comparison, the entire country of Ireland used 24 terrawatts in the same time period. This obviously has high environmental cost, although blockchain proponents say this could be offset by moving to cleaner and renewable energy. It’s for this reason that countries like Iceland with huge supplies of geothermal energy have become hubs of bitcoin mining activity.

The move is justified because oversight is reduced when private actors can enforce legal rights (think of shareholder suits for fraud). This approach will also hasten legal protections on-chain – the ultimate goal for any regulatory scheme. Such capabilities are available through layer 1 protocols that enforce the law on-chain. These protocols obviate the need to seize private keys from pseudonymous criminals by enabling direct action on wallets and smart contracts.

How are cryptocurrencies and/or virtual currencies defined and regulated in your jurisdiction?

Each blockchain is a unique and secure ecosystem, providing lucrative benefits to others. Imagine a system where users can benefit from each without stressing the need for interoperability. Lovell stressed the need for interoperability and its pivotal need in the financial institutions working on tokenizing real-world assets. Only with this facility can they ensure that a closed ecosystem does not constrain liquidity. The file containing this article can, in theory, simply be stored on one computer and accessed over the internet by however many people want to use (i.e read) it. A blockchain, on the other hand, is duplicated, in its entirety, across many computers.

With respect to smart contracts, blockchain may further be suitable for the management of access authorization and the grant of licenses. For example, access to digital online content[12] (e.g., music, videos, photos, other documents) would only be provided if the respective payment made by the user was validated in the blockchain. Similarly, in case of licensing relationships, the smart contract/blockchain could track the grant of licenses and/or sublicenses and the orderly payment of royalties (which could be calculated based on the number of acquired licenses or other data). Mandating minimum enforcement standards is one, but the multijurisdictional nature of public blockchains makes this impracticable. Self-interest should drive adoption given that property becomes more valuable as legal protections are strengthened. A third is for influential agencies like the US Treasury and the Securities Exchange Commission to offer a regulatory sandbox when providers use blockchains with on-chain enforcement.


For instance, General Data Protection Regulation (GDPR) assumes data is centralised on at least one legal entity, while blockchain decentralises data storage to an anonymous network of nodes. Blockchain technologists should study the regulations thoroughly before implementation. High level of data integrity
From the verification process to storing transactions, data is verified by a consensus algorithm specific to the blockchain protocol. The integrity and security of blockchains make them immutable, transparent and unimpeachable.

With a centralised system of control, a single weak point could, if compromised, place the entire business network at risk. Decentralised Blockchain can, therefore, significantly increase accounting and transaction security. In light of the explosive growth of e-commerce, online banking, and the proliferation of mobile transactions globally, businesses need transaction processing networks that are fast, secure, transparent and efficient.
