… most obviously the community is growing - we are about to have an additional 25 validators. Before the Cosmos Hub 3 upgrade, a governance proposal can only serve as a signaling mechanism.
…Cosmos Hub 3 enables voters to modify on-chain parameters without a hard fork. This is a very powerful feature because there are many potential parameters that can be changed on-chain, and each parameter change has the potential to have a significant impact on crypto-incentivized games.

In addition, CosmWasm is officially released.

If you are a Rust developer integrating the Cosmos SDK into CosmWasm, it means:
① You only need minimal Golang knowledge.
If you are a Go developer who also incorporates CosmWasm into the Cosmos SDK, the benefits include:

③ You can use Rust's type safety and testing, as well as the relatively common coding and encryption signatures in Rust-this is ideal for developing highly secure blockchain applications used in DeFi.

Algorand has recently implemented the innovative Algorand Smart Contracts on the first layer, providing multiple application possibilities for controlled transactions using simplified script templates. And these functions are integrated in the first layer of Algorand, with unprecedented speed, less complexity and lower cost, so as to solve the needs of most practical use cases. It is more efficient than other techniques because it consumes fewer computing resources and is less susceptible to programming errors.

8 NEAR

...Layer 2 is developing very rapidly in the field of research and development. In 2020, we will explore in 3 directions: channels, chain-based protocols, and zkp-based protocols. We are actively participating in the research of the zero-knowledge proof protocol, and are building prototypes and channel prototypes based on the zkp protocol.

…In 2020, we will dedicate significant resources to growing the developer community. The success of Nervos Network depends heavily on the developers who experiment and build on the platform. We will deploy these resources through two major programs: the Grants Program and the Regional Leaders Program to encourage developers to optimize their experience and develop Layer 2 projects. In addition to these initiatives, we will vigorously develop: engineering infrastructure, key protocols and standards, ecosystem integration, and education activities and hackathons for developers, etc.

Calculate the number of blocks of the light node and serve the RPC endpoint of the light node
nearcore released v0.4.8
Fixed shard management and network routing table memory leaks in deterministic components
The stake weight is used to store the hash instead of the actual value in the tree node
nearshell released v0.16.0
Allow simpler form input for attonear with NEAR as default unit
Added an API for signing single ratio transactions in the near wallet
