History:

This particular work took couple of years which originally started for me as a cross chain project based on Steem 0.19.2 which unfortunately was not completed. It was then that @jonathan.bahai magically mentioned similar ideas and cross chain work -- it was quite surprising back then that I almost thought he is mocking me after checking what I am working on ;-) Synchronicity in play for sure!! It took quite a while and amazing work from my team of rockstar developers getting this done.

What is it ? - its not a gateway

We have a trustless system which is part of the core chain and right now we are connected to Bitcoin. In the coming months we are expecting to be able to integrate with Ethereum and few other chains based on demand.

About

SON

Sidechain Operator Nodes (SONs) are democratically elected, decentralized Gateways. Peerplays has implemented cross-chain functionality with the other blockchain network. This enables functionality such as end-to-end withdrawal and deposit of coins between the Peerplays and networks like Bitcoin blockchain network. Currently SON supports Bitcoin blockchain and other blockchain networks will be added in due course.

Bitcoin Sidechain

The SON enables seamless integration of Bitcoin (BTC) token interoperability with Peerplays blockchain. This enables functionality such as end-to-end withdrawal and deposit of Bitcoin between the Peerplays and Bitcoin blockchain networks.

NFT

A non-fungible token (NFT) is a special type of token that represents a unique asset. They are blockchain assets that are designed to not be equal. NFTs have a wide range of applications including video games, fine art, movie tickets and more.

The most popular type of NFT is based on the ERC-721 token standard. Creation of ERC-721 tokens has exploded over the past year with a huge wave of digital collectibles and game-based assets coming online.

Peerplays provides an enhanced version of the ERC-721 token standard wherein there can be both non-fungible and semi-fungible tokens based on the discretion of the token creator. The Peerplays standard also provides flexibility to mark the NFTs non-transferable and non-sellable if the creator choose so.

Non-Transferable Tokens

The non-transferable tokens offers unique capabilities to Peerplays blockchain where by dApps can provide rewards, issue course completion certificates similar to university certificates etc.

Marketplace

Peerplays marketplace is a decentralized, peer-to-peer marketplace for Peerplays NFTs.

The marketplace provides both auction and reverse auction functionality. An NFT owner can list his asset for sale in the marketplace for a desired price and other users can bid to buy the asset until the sale expires. Similarly, users can create a buy offer to an NFT owner.

HRP

Hierarchical Role Based Custom Permissions (HRPs) provides a more sophisticated and fine-grained control of account permissions. Users of the Peerplays blockchain can create new permissions and link operations that can use the created permissions instead of active and owner keys. This increases the security of the user accounts wherein the user need not use the critical active and owner permissions all the time.

Who Should Upgrade?

The witnesses on the ALICE Public network are requested to upgrade to this release. The hard-fork date/time is set to Monday, December 21, 2020 00:00:00 UTC
