Ethereum`s Limitations 

The most significant limitation of Ethereum – like with Bitcoin – is its scalability, which, as with Bitcoin, is hard to achieve without sacrificing  decentralisation or security,  Fiat currency achieves security and scalability but sacrifices decentralisation to do so. In contrast, Bitcoin achieves decentralisation and security but sacrifices scalability to do so. At the moment… Continue reading Ethereum`s Limitations 

Ethereum Ecosystem and Innovations

Since 2013, many decentralised applications have been built on Ethereum. The surrounding Ethereum ecosystem has grown to a market cap of over $140 billion. Famous decentralised applications include digital art marketplace Foundation and browsers such as Brave that let you earn cryptocurrency from browsing the internet.  More recently, Ethereum has powered the explosion of the… Continue reading Ethereum Ecosystem and Innovations

Ethereum`s Unique Characteristics and Ecosystem

So how does Ethereum achieve these objectives? Ethereum was designed as a blockchain with a built-in ‘Turing complete’ programming language – called Solidity – that can be used to create smart contracts. All that ‘Turing complete’ means is that Solidity is a programming language capable of programming for any hypothetical computation. Thus, in theory, any… Continue reading Ethereum`s Unique Characteristics and Ecosystem

What is Ethereum

Ethereum is a blockchain-based system where anyone can build and securely deploy any digital service without going through a formal, centralised approval process – such as getting an App added to Apple’s App Store.  It is the brainchild of Vitalik Buterin, a Russian born computer programmer, who was an early Bitcoin advocate, but thought it… Continue reading What is Ethereum

Lightning Network – Bitcoin`s killer Application? 

By enabling the transaction to occur through payment channels rather than on-chain, the lightning network offers a potential way for bitcoin to address its scalability problem. People have likened this to what fiat currency did for gold, arguing that the lightning network could be bitcoin’s ‘killer application’.  The analogy works when you think about it,… Continue reading Lightning Network – Bitcoin`s killer Application? 

Lightning Network: Channels and Invoices

The Lightning Network is an example of Layer 2 bitcoin service. It is an off-chain approach first formally proposed in a paper by Joseph Poon and Thaddeus Dryja in 2015. The technology uses micropayment channels to scale the bitcoin blockchain’s capability by processing transactions more efficiently.  Micropayment channels are opened between two parties looking to conduct a… Continue reading Lightning Network: Channels and Invoices

Separating the Layers

The idea of Layer 2 is to build protocols or secondary infrastructure (e.g. the Lightning Network) that can interact with a fundamental base blockchain (Layer 1 e.g Bitcoin) but not be restricted by its scale limitations. This is where we make a clear distinction between on-chain (Layer 1) and off-chain (Layer 2).  Transactions described as… Continue reading Separating the Layers
