Three serious competitors for Ethereum in 2021

Ethereum has become the blockchain of choice for many developers of decentralized applications (dApp). Ethereum has by far the largest developer community, even surpassing Bitcoin’s. Still, there have been more and more serious projects recently that could erode Ethereum. The three most promising Ethereum competitors under the microscope.

After several years of development, the first phase of Ethereum 2.0 has started. The major upgrade has been in planning since 2015 and the fact that it is far more difficult to change the engine in a moving vehicle than to build from scratch speaks for itself. That is why many former ETH developers took the opportunity and developed their own blockchain. Will Ethereum lose its first mover advantage?

Cardano vs. Ethereum

Cardano (ADA) has been one of the most promising smart contract platforms in the crypto space for some time. The project was originally founded by mathematician Charles Hoskinson, a co-founder of Ethereum. Charles Hoskinson left Ethereum in 2014 and then created the for-profit IOHK Foundation.

The cryptocurrency ADA made more headlines this year as Cardano introduced the Shelly upgrade on its mainnet. Shelly enables Cardano to be staked and, similar to Ethereum 2.0, is just one of many phases. Shelly is only the second phase of the ADA update and three more upgrades will follow. In the end, Cardano should be a scalable blockchain on which smart contracts can also be programmed.

In addition, Cardano ultimately wants to operate an on-chain governance model in which every ADA holder should be able to participate. In the future, Cardano is expected to be best suited for applications in the finance and organization sectors. This is because, unlike Ethereum, Cardano is programmed in Haskell. Haskell is a programming language that is particularly suitable for business applications and data analysis.

Tezos vs. Ethereum

Tezos was founded in 2018 and the foundation behind Tezos, like Ethereum, is located in Zug, Switzerland’s crypto valley. Arthur and Kathleen Breitman developed Tezos. However, the early years of the blockchain project were often characterized by internal power struggles coined between the Breitmans and the Tezos Foundation.

Tezos uses a delegated proof-of-stake consensus mechanism that it calls “liquid proof-of-stake”. However, researchers have found that Tezos, while not having the same level of decentralization as Ethereum, is more decentralized than many other DPoS blockchains.

This is mainly due to the fact that Tezos has not prescribed an upper limit for the number of nodes. This makes it possible for Tezos to become more and more decentralized as it grows. In the future, Tezos and Ethereum 2.0 could definitely compete with each other in terms of security and decentralization. The main difference between the two blockchain projects is Tezos‘ on-chain governance model.

When the Breitmans conceived the Ethereum competitor, their vision was that the Tezos platform could upgrade itself. The goal is to create a competitive blockchain that can effectively evolve from within. Each Tezos holder can vote on what should happen next with the platform.

In contrast, Ethereum has always had off-chain governance. In all probability, this will not change anytime soon. However, it is unclear which system will prove to be superior to the other.
