The Casper Network is a fully decentralized (permissionless), scalable, and highly secure Proof-of-Stake layer 1 blockchain. Casper has solved the layer 1 trilemma; it is secure, fully decentralized, and scalable/fast.
Powered by Highway, an innovative, correct-by-construction (CBC) Casper-based Proof-of-Stake consensus protocol, Casper is leveraging popular workflows, innovative developer tools and multiple programming languages. Casper makes blockchain services easier to use, more upgradable and more predictable, thus removing barriers to mainstream adoption.
Developers can build on Casper utilizing common languages, plus Casper has built a Solidity Compiler which allows those developing currently on Ethereum using Solidity to quickly migrate to Casper in two easy steps so that they can start to build and test their applications on the future of Ethereum today, instead of waiting 4 to 5 years from now.
Key Highlights
CBC Casper: Early Ethereum developers designed CBC Casper to bring finality and flexibility to blockchain-based consensus protocols. Finality increases security as it guarantees past decisions are irreversible and makes decisions deterministic rather than probabilistic. Furthermore, Casper is flexible and block times can adjust based on network conditions. These benefits make transaction settlement faster and improves users’ confidence in the protocol’s data output.
Casper Exceeds the Goals of Ethereum 3.0 - Faster, And We Enable a Seamless Transition from Ethereum
Enterprise Grade: The protocol is designed for enterprise adoption with focuses on flexible privacy permissions, low latency, and security. Casper allows enterprises to choose between public, permissioned, and private network iterations depending on their confidentiality preferences without sacrificing security or performance. This has attracted multiple enterprise and Web3 teams to develop partnerships with Casper.
Future Proof: Casper is built to withstand changing business and developer preferences. Upgradeable contracts ensure devs and enterprises can improve their applications over time; Stable/predictable gas fees ensure apps remain performant even when network activity spikes; WebAssembly support ensures non-crypto devs can onboard quickly; On-chain governance mechanisms ensure governance based on network contribution and reputation.

Technology Overview

  • Started with Vlad Zamfir’s 2017 CBC Casper whitepaper, but the Casper team then finished the architecture (mathematical liveness proof) and actually coded the future of Ethereum 3.0, today.
  • Began coding in Nov. 2018, launched Alpha Testnet in March 2020, currently in the final stage of Testnet (Delta TestNet).
  • Currently, 120+ validators (incl. staking providers such as HashQuark, SNZ Pool, Stake.Fish, Stake.US, etc.).
  • Consensus algorithms code audit by Trail of Bits recently completed with no major items to correct.
  • Currently integrating with BitGo (more on this below) and undergoing smart contract audit and soon pressure testing of network by Cardinal Cryptography.
  • MainNet launch on track for early March 2021.
With the ​Delta Testnet​, our network is now “permissionless” which means validators can join and leave the network independently. The Testnet currently has 100 slots available for validators. Through this stage of Testnet, we will gradually increase the number of validator slots to approximately 200 by the time of Mainnet launch.

Casper's Ecosystem - Update Jane 22th
Casper is heavily focused on enterprise adoption with MOU’s signed with several notable enterprises. Due to NDAs we cannot disclose the names of a few of these partners yet, here are some of the businesses we’re working with:
  • Hera - Gold backed asset token (Anthem Gold) utilizing the casper network
  • PlasmaPay - A decentralized financial services and infrastructure platform.
  • Actus -
  • IPwe - Intellectual Property - top provider for IP rights management migrating from IBM’s

We’ve also just recently signed a partnership agreement with BSN as one of their public chain partners to increase awareness and achieve more engagement from the blockchain and application development community in China.
Along with these larger institutions we’re also working with several startups, Dapp developers and projects that are currently interacting with our network. Our current version of testnet has over 60 participants with 100 slots available for validators. Through this stage of Testnet, we will gradually increase the number of validator slots to approximately 200 by the time of Mainnet launch.

China & Asia Focus

From day 1, Casper has appreciated the importance of the Chinese market. In addition to dozens of visits to mainland China, the team is heavily focused on community development and engagement in China. With over 10,000 community members through WeChat and the Lichang platform, Casper continues to expand its reach in China through their strategic partnerships with notable advisors, investors and partners such as: Huobi Pool, Hashkey Capital, NovaClub, Rocktree Capital, QCP/QSN, Consensus Lab, WaterDrip Capital, Chain Capital, Jinse/Mars Finance and Oasis capital. In addition to global investors, many retail and institutional investors from China purchased CSPR in the private round, providing distributed community involvement and liquidity for the token when it trades.
Casper will hire a China Country Manager (anticipated prior to Spring Festival), which is a ​new position​ on the Casper business team and will be working directly with our China based advisors and investors to develop a massive China-focused marketing Campaign prior to launch.

Developer Growth

Casper is planning a Hackathon & Casper Building Incentives campaign co-hosted with Gitcoin, planned for early 2021. Casper will activate a month-long campaign in late February / beginning of March focused on our Mainnet launch and showcasing several aspects of our core value prop to Web3 builders.
