Privacy may be the only thing DeFi fans and cypherpunks can agree on. In 2020, political censorship is motivating further adoption of cryptocurrencies which are anonymous - that means the senders’ and receivers’ identities are not linked on the blockchain. From the other side, the DeFi community is waking up to the need for confidential transactions, where the amount being sent is hidden. This will be essential for smart contract derivative instruments, peer-to-peer lending and the like.
Ethereum is one of the most well-known blockchains, and it is about to receive a significant upgrade. The crypto community is now keeping an eye out for ETH 2.0, and for a good reason. The 2.0 upgrade will bring a host of changes to the network that will make Ethereum faster and more secure than ever before. The changes that this upgrade is going to bring in a host of changes like - proof-of-stake, Sharding, eWASM, Plasma, and the Raiden Network.
Since Ethereum first went live in July 2015, developers have stayed the course to improve it consistently. And in comparison to other upgrades over the years, the upcoming phasing in of ETH 2.0 will introduce two significant improvements: Proof of Stake (PoS) and Shard Chains. The shift in the underlying consensus mechanism away from the existing Proof of Work architecture will improve scalability, accessibility, economic incentives, energy efficiency, and lower barriers to entry, amongst other things.
With ETH 2.0 just around the corner, now is a good time as any to look into one of the most critical updates it’s bringing along - proof-of-stake (PoS). In this article, we will look at why the current proof-of-work (PoW) system isn’t refined enough for future scalability needs and then see how eth 2.0 is looking to integrate PoS.
Over the past few days, we gave you a general overview of how Ethereum 2.0, or ETH 2.0, works and then showed you ETH 2.0 Staking and the Casper Protocol’s nuances. In this one, we are going to look into another massive feature of ETH 2.0 – Sharding.
As you are probably aware, we are on the verge of an Ethereum revolution, colloquially known as ETH 2.0. This upgrade is going to bring in a lot of innovations to the popular Ethereum protocol.
Ethereum 2.0 will trigger a seismic shift in the crypto space. Some of the changes that this upgrade is going to trigger are:
The transition to Casper protocol
Raiden state channels
Raiden and Plasma are layer-2 protocols that allow Ethereum to conduct thousands of transactions off-chain in the form of state channels and side chains. Plasma, in particular, can theoretically allow a side chain to process thousands of transactions and commit just one single hash to the main Ethereum blockchain. While this sounds pretty amazing on paper, there is a significant problem here. If there is some dispute in one of these side plasma chains, there isn’t a proper mechanism that the users can use to exit the protocol efficiently.
eWASM is one of the many innovations that Ethereum is looking to implement to make its jump to Ethereum 2.0. Many believe that eWASM will help create an ecosystem that’s fast, scalable, and flexible, encouraging developers to build complex smart contracts on top of Ethereum 2.0’s protocol. This comes in addition to the many different aspects of ETH 2.0 which our previous articles on Staking, Sharding, Ethereum Layer-2, zk-SNARKs and much more explains. So, before we go any further, let’s familiarize ourselves with Ethereum 2.0.
