10 Most Influential Crypto Events of 2021

Major Crypto Events in 2021

Cryptoverse went through many ups and downs in 2021. Numerous innovations, developments, and technology had come in place, some of them were proven a boon for decentralized finance, and some were shut off with initial rollout. In Crypto 2021, many fascinating and revolutionary projects have helped crypto to grow its market cap.

There is a famous quote that if you want to know somebody, look back into their past. The quote is extremely suitable for cryptoverse also. To envisage crypto 2022, you must take a dive into Crypto 2021. Initiatives that were started in the last year will certainly influence crypto this year. So, let’s take a look over the top 15 moments of cryptoverse to know what story we shall see in 2022.

1. Bitcoin Taproot Upgrade

In November 2021, the world’s largest blockchain Bitcoin created history after revealing the Taproot upgrade after a 4-year long span. This upgrade enhances blockchain efficiency through batches of multiple signatures and transactions. This will help the blockchain to verify transactions rapidly. In the upcoming months, the transactions on Bitcoin are expected to scale up due to this fascinating up-gradation.

2. Ethereum 2.0 Upgrade

Ethereum 2.0, the most-awaited and promising project in blockchain history. The developers have decided to roll out its upgrade into three-phase. The first phase was already launched in Dec 2020, which was the induction of the proof-of-stake mechanism through the Beacon chain. 

In 2021, Ethereum initiated the preparation of phase 2 by launching the Kintsugi testnet. In the second phase, the Ethereum mainnet will merge with the beacon chain, hence it will replace the proof-of-work mechanism with proof-of-stake. 

This upgrade will make Ethereum 2.0 more energy-efficient and hence transaction costs will also reduce. The merger was expected to launch in 2021, but due to delay now it is expected in the first half of 2022. 

The third and last phase, sharding, is planned for 2023. The final phase will make the Ethereum blockchain capable of executing multiple transactions at the same time. 

3. Cardano Hard Fork Update & Polkadot Parachain Auction

The world’s third-largest blockchain, Cardano doesn’t want to be left out in the jump of the cryptoverse. That’s why developers are continuously putting efforts to enhance blockchain performance. 

Last year, Cardano received the smart contract capability in face of Alonzo hard fork update. It will continue to implement upgrades to improve the blockchain experience. Its upcoming upgrades include Goguen, Basho, and Voltaire.

Polkadot and Kusma network came out with different kinds of auctions for its parachains in 2021. As per the auction details, the Parachain auction allows defi projects to reserve slots out of 100 parachains slots through the highest Bid. 

In the first year of auction, 20-30 parachain will be given on leases. Last year, the first five slots were reserved by Acala, Moonbeam, Astar, Parallel, and Clover respectively.

4. Increasing Layer-2 Scaling Solutions’ Integration

In the last few years, the DeFi graph soared exponentially and 2021 is not exceptional for this. The spontaneous boom in DeFi activities and projects has helped DeFi to embark on new milestones. In 2021, the total value locked (TVL) in Defi had surpassed $110 billion bar. However, it ended the year with $86 billion TVL.

With the expansion of DeFi activities, the protocols have started integrations with layer-2 scaling solutions to make the transactions faster and cheaper. Some leading scaling solutions are Arbitrum, Polygon, Optimism, Parastate, and Cartesi.

For example, last year, the third-largest lending and borrowing protocol, Aave, announced its integration with Ethereum layer 2 scaling solution, Polygon. Uniswap was also integrated with Optimism in July 2021.

However, the UN has appreciated the alternate option, proof-of-stake (Pos). 

  • United States

Last year, U.S regulatory authorities passed the most controversial ‘Infrastructure bill’ under the presidency of Joe Biden. The bill contains provisions to impose a tax on cryptocurrency trading and yield. Many crypto intellectuals and entrepreneurs have opposed this bill as it degrades decentralized finance.

DAOs (Decentralized Autonomous Organisations) are another most versatile concept in decentralized finance. In 2021, some DAOs formed to achieve certain goals by the contribution of members.

Constitution DAO was formed to place a bid to acquire a rare copy of the U.S constitution. To achieve that goal, members of DAO have raised $47 million. But surprisingly, during the auction, the Constitution DAO’s members have limited their bid for $41 million, while the competitor, Ken Griffin has outbid Constitution DAO and won that rare physical copy of the Constitution.

Last year as a part of the FreeRoss moment, ‘The Ross Ulbricht Genesis’ non-fungible token (NFT) collection’s auction was organized.

These cyberattacks certainly created fear among crypto investors and entrepreneurs, but they will not be able to resist the pace and expansion of cryptoverse. The developer community is working consistently to resolve issues and prevent incidents. In 2022, numerous developments are going to take place, which can be a game-changer for cryptoverse.
