Core Features

Proof of Stake (PoS)

Cere’s PoS Blockchain is an open source blockchain project built using Substrate, which follows the Nominated Proof of Stake mechanism to reach consensus. Using this approach, token holders can pool their resources together to nominate validators by staking validators of their choice to represent them, sharing a portion of the profits in return for their support if the validator nominated operates well.

Validators contribute to the overall security of the decentralized network by locking monetary assets in a staking pallet in an operation otherwise known as Staking. Token rewards are distributed to Validators (and their nominators) for good behavior, and token slashing is used to punish those who are not behaving in the best interest of the network.

The Nominated PoS mechanism used by the Cere Blockchain opens up the possibility for a more decentralized network, as even smaller token holders can actively participate in staking by building up a larger staking pool through the nomination process.

💡 Validators currently operating the Cere Network Blockchain can be seen on stats.cere.network/#/staking & https://explorer.cere.network/#/staking.

What is a node?

Nodes are basically servers and other infrastructure that run a blockchain.

Node Types

Cere Network is Substrate-based chain with 3 types of Nodes: Full Nodes, Archive Nodes, and Light Nodes.

Cere’s Full Node URLs can be found in the Blockchain Info toggle above.
Archive Nodes are used by utilities that need past information – like block explorers, council scanners, or any other tools that need to query past on-chain data quickly.
- Cere Network runs its own Archive Node. More details here.
- In Q1 2023 Cere partnered with Republic Crypto | Runtime to host a secondary Cere Archive node for the Testnet and Mainnet to increase the availability of the Cere Blockchain for Cere Explorer and Cere Bridge tools.
There are no Light Nodes in operation at this time.

Governance, Staking/Slashing, Treasury, and Council docs on docs.cere.network are written with the Cere community in mind.

New Features

Substrate Version | `polkadot-v0.9.19`

NEW: In December 2022 Cere updated it’s Substrate based Blockchain framework from Polkadot v0.8.27 to v0.9.19. Node client consensus required for upgrade execution among all Validator Client nodes was reached in < 60 minutes!

All related tools have been updated as well: https://bridge.cere.network, https://stats.cere.network, https://explorer.cere.network.

We integrated the latest security fixes, performance fixes, and many new features, including upgradability to Smart Contracts, which are required for the next generation of the Cere DDC protocol.

Bags

NEW In the 2.33 release of Cere PoS Node, a feature was added for validators called “Bags.” To briefly recap what the Bags features is, consider the following variables:

“N”, the number of nominators who set their nomination intention, in a given network.

“A”, the number of nominators that can be included in an election process, and consequently become active and rewardable.

Currently, these two values are fixed. With the new bags-list, we can decouple these two values to allow many more nominators to set their intention (i.e. large value for “N”), and only pick a subset of them (“A”) for elections and rewards (based on stake). This means now that once “N” and “A” are different values, it might be important for some nominators to ensure they are taking their best possible position in the bags-list! Check out the bags-list page on the Polkadot wiki for more details.

SS58 Keys | `cere-`

NEW In Q1 2023 Cere selected a specific format for Cere to use instead. If you’re curious to learn more about Substrate addresses, check out this article.

The prefix in Substrate code will be 54. For end user accounts, it will start from 6. Users will be able to see it in the Explorer and Polkadot.js extension after associating their account with the Cere Blockchain.

💡 See update announcement for more details.

Tools & Apps

Cere Bridge

The Cere Bridge (https://bridge.cere.network/) can be used to transfer $CERE ERC20 tokens on Ethereum to the Cere Mainnet, one way. On Polygon, two-way transfers are supported: from the Cere Mainnet to Polygon and from Polygon to the Cere Mainnet.

The Cere Bridge consists of the EVM Smart Contracts, Substrate pallet, Network Relayer app, and a Bridge Frontend UI.

The Cere Bridge project was forked from ChainBridge – a modular multi-directional blockchain bridge to allow data and value transfer between any number of blockchains. The official ChainBridge docs are available here.

A high-level diagram showing how tokens will be transferred from Chain A to Chain B can be found below. More information about ChainBridge can be found in the docs.

Cerestats

Cerestats is a block explorer for Cere Network that shows Cere Network live statistics, block production details, the validation process, staking information, and more.

The Faucet functionality offered on Cerestats allows developers to easily send themselves $CERE tokens on the Testnet.

This project was forked from https://github.com/polkastats/polkastats.

Cere Explorer

The Cere Explorer provides a view and interaction layer from a browser into the Cere Blockchain network, gives Validators and Nominators an interface to stake their CERE tokens in exchange for staking rewards, and will also hold all the Governance proposals and discussions submitted by the community. This tool essentially facilitates interactions between users and the Cere Network.
