According to data compiled by CryptoRank and Santiment, Cardano was the most developed crypto project on GitHub in 2021, with over 140,000 events.
Rounding out the top three were Kusama and Polkadot at second and third places, respectively, with roughly the same number of events over the year. Cardano beat Ethereum’s development activity by a wide margin, with the latter coming in fourth place. Santiment defines a GitHub event as either creating an issue, creating a pull request, commenting on an issue or pull request, or forking/starring/watching a code repository, among others.
In a live Youtube session last week, Cardano founder Charles Hoskinson revealed that there are approximately 127 projects under development on the Cardano blockchain. In addition, Hoskinson expects the number of ADA users to grow tenfold from the existing 2 million, thanks to the growing popularity of nonfungible tokens, or NFTs.
Cardano’s technological advancement is also gaining traction post-Alonzo. One of the blockchain's notable works in progress is the layer-two Hydra upgrade, which channels transactions off-chain to staking pools without partitioning the ledger itself. Theoretically, it could enable advanced linear scaling of the network with hundreds of “hydra nodes” each processing hundreds of transactions.
Another notable mention is a novel fintech funding mechanism, known as the initial stake pool offering (ISPO), that’s unique to the Cardano blockchain. In this setup, blockchain enthusiasts delegate their cryptocurrencies in a protocol and receive tokens of the new project they fund as rewards. In contrast, the ADA staking rewards go to the developers. Funds do not leave the delegator’s wallet, making the process rather secure. One such project, Genius Yield, saw its ISPO pools surpass $118 million within 24 hours.
