2021年区块链生长：Filecoin跃居最活跃开发项现在五名！

The last 12 monthsExecutive summary

ü ETHereum is still the most active developed Blockchain protocol,followed by Cardano and Bitcoin.

ü Multi-chain protocols like Polkadot, Coos and Avalanche are seeinga consistent rise in core development and developer contribution.

ü In the year of its public launch, decentralized file storage projectFilecoin jumped straight into the top 5 of most active developed projects.

ü ETHereum killers Tron, EOS, Komodo, and Qtum are seeing a decreasein core de-velopment metrics.

ü DeFi protocols took the space by storm with ETHereum being thechoice of the undering blockchain and art contracts platform. They saw anincrease in core development and developer contribution activity over the yearwhich was all open sourced. The most active projects are Maker, Gnosis andSynthetix, with Aave and Bancor showing the most growth. SushiSwap and YearnFinance, both launched in 2020, quick grew toward and beyond the developmentactivity and size of most other DeFi protocols.

ü NFT and 元宇宙 projects like collectibles, gaming, crypto art andvirtual worlds saw a market-wide increase in interest, but most follow aclosed source devel-opment approach. A notable exception is Decentraland, whichhas development activity on the levels of some major blockchain technologieslike Stellar and Al-gorand, and ahead of some of the most popular DeFiprotocols like Uniswap and Compound.

In the enterprise blockchain domain,Hyperledger has higher development activity than Corda, but Corda has slightbetter growth.

Top 5 most active

The most active developed protocols areETHereumand Cardano, in a league of their own considering code commits with 866and 761 average week commits.Bitcoin (441), Filecoin (405) and Polkadot (385)complete the top 5 at levels around 50% of ETHereum and Cardano.

Looking at the month active developers,ETHereumleads with 220 month active core developers on average, followed byHyperledger (149), Cardano (144), Bitcoin (103) and Filecoin (92).

Filecoin saw good growth in coredevelopment, especial in the third quarter as they were preparing for theirmainnet launch in mid October. In May, they launched the second phase of theirTestnet, which was the last major milestone before mainnet launch andcorresponds to a local maxima in the commits graph as they released twointeroperable Filecoin implementations (go-filecoin and Lootus), secure proofs (WinningPoStand WindowPoSt), Drand, an overview of the network’s cryptoeconomic structures,a new documentation site, and new security audits before launch. Inpreparations for Slate (an open source file sharing network de-signed forresearch and collaboration) in September and for Mainnet launch on October15th, the commits rose by 175% from opening weeks.

Filecoin saw a steady high level of monthactive developers, peaking around the October mainnet launch.
