Pantos is an open-source research project founded by the team behind Bitpanda and is being developed in collaboration with researchers at the Christian Doppler Laboratory Blockchain Technologies for the Internet of Things (CDL-BOT).

CDL-BOT is an application-oriented research laboratory where expert scientists cooperate with innovative companies. The laboratory is funded by the Austrian government via the Christian Doppler Forschungsgesellschaft and the commercial partners, the Pantos GmbH and the IOTA Foundation. It is divided into two different modules. The first department is called “Cross-Blockchain Transactions” and is based at the Hamburg University of Technology (TU Hamburg). The second module, “Lightweight Blockchain Protocols”, is located at the Technical University of Vienna (TU Wien).

The Pantos project aims to establish an open standard for truly decentralised cross-blockchain token transfers and blockchain interoperability. Over the course of the last few years, several working Proof of Concept solutions have been released, displaying derived research results and highlighting the importance of blockchain agnostic solutions.

While today's interoperability solutions are often designed in a (semi) centralised manner, Pantos aims to enable the transfer of tokens to other blockchains without the need for an intermediary blockchain, thus always preserving the security and integrity of the involved blockchains.

NuCypher is a decentralized encryption, access control and key management system (KMS), encryption service for public blockchains. NuCypher offers end-to-end encrypted data sharing on public blockchains and decentralized storage solutions.

NuCypher allows users to share private data between a number of participants in public consensus networks, using proxy re-encryption (PRE) technology. This decryption technology makes NuCypher much more secure and protected than traditional blockchain projects based on public-key encryption, according to NuCypher.

NuCypher (NU) are the native tokens used on the larger NuCypher network. The tokens are used to incentivize network participants for performing key management services and accessing delegation/revocation operations on the network.

The NU tokens are also used for staking to run a NuCypher worker node. The NuCypher network is protected against malicious staking, and would automatically slash a suspected user’s rewards.

NU is also used on the network for participating in the NuCypher DAO. The NuCypher DAO is the protocol that controls network parameters and smart contract upgrades on the network. Users who stake NU can also participate in validating DAO proposals.

NuCypher was co-founded by Mikhail Egorov (the founder of Curve) and MacLane Wilkison. The white paper for NuCypher was first published in June 2017, but the testnet did not launch until November 2018.

Egorov formerly served as the CTO of NuCypher. He is a security researcher, physicist and scientist from the Moscow Institute of Physics and Technology.

Co-founder MacLane is a software engineer and the CEO of NuCypher. Prior to his involvement in blockchain, he worked as an investment banker at Morgan Stanley, where he provided financial services to enterprises in technology, media and telecommunications.

Both Egorov and MacLane participated in the U.S. startup accelerator Y Combinator in the summer of 2016. The following year, the whitepaper for the NuCypher project was published.

NuCypher launched its private testnet in 2018. The private treatment launch saw participation from major staking infrastructure providers including Bison Trails, Figment, InfStones and Staked.us.

The public testnet of NuCypher began in October 2019. However, the incentivized public testnet began in January 2020. The mainnet of NuCypher launched in October 2020 after distributing $45 million in NU tokens to nodes.

Unlike most blockchain projects that are designed to serve customers, better transactions, IoT operations, voting mechanism, and the like, NuCypher was created for other blockchains. NuCypher is a privacy layer for blockchains.

NuCypher provides a privacy infrastructure for the decentralized web with proxy re-encryption (PRE), threshold signatures (TSS), distributed key generation (DKG), and other threshold cryptography.

Using the NuCypher network, users can conditionally grant and revoke access to data with multiple users at a time. NuCypher's encryption service provides almost unparalleled security for sensitive data transfer. It combines this with the trustless and censorship-resistant nature of conventional public blockchains.

The cryptographic libraries of NuCypher include;

At NuCypher’s mainnet launch in October 2020, there was a total supply of 1 billion NU tokens. According to the release schedule, 3,335,938 and 4,460,000 NU tokens are released monthly to the SAFT Series 2 and Team/Equity investors every month.

The WorkLock, NuCypher’s novel network node setup mechanism, is expected to get 225,000,000 NU tokens in April 2021. Factoring in the monthly release of the NU tokens, 1,088,876,961 NU tokens have been issued with 392,750,000 currently in circulation.

The network has a max supply of ~3.89 billion NU tokens. The tokens are released monthly as rewards to stakers, according to the staking economics paper.

NuCypher is a layer 2 resource allocation protocol on Ethereum that uses a proof-of-stake (PoS) mechanism to coordinate worker nodes.

The network runs on a novel node distribution mechanism which NuCypher calls the WorkLock. To run a NuCypher node, a minimum of 2,000 node operators would need to stake 353,913.

The minimum lockup staking period is 30 days. However, NuCypher doesn’t guarantee that staking for longer than one year will provide greater benefits in terms of earning rewards. Unless the user opts out after a staking period, staking rewards are automatically restaked after each period.

Equities are stocks that trade on traditional regulated exchanges. FTX lists tokens on select equities. These spot tokens are backed by shares of stock custodied by CM-Equity. They can be redeemed with CM-Equity for the underlying shares if desired.

CM-Equity is fully regulated in Germany, and is a licensed financial institution permitted to offer such products. All FTX users who trade tokenized stocks may also have to become customers of CM-Equity, and pass through CM-Equity's KYC and compliance. Furthermore, all trading activity may be monitored for compliance by CM-Equity. CM-Equity custodies the equities at a third party brokerage firm. CM-Equity (not FTX Trading LTD) provides the brokerage services.

AppCoins is an open and distributed protocol for app stores based on the Ethereum blockchain and smart contracts. It redesigns app advertising, in-app purchases (IAP), and app approval flows through a circular model. As a higher share of the advertising and IAP revenue is kept within the app ecosystem, more value is retained in the app economy. Being an open protocol, it would theoretically provide more transparency and trust. Multiple app stores can implement and benefit from this and stakeholders will have to contribute to its development and adoption. Furthermore, API integration will streamline implementation.

AppCoins integrates app stores, users, developers, advertisers, and OEMs. This system is app store agnostic, existing across different mobile platforms (Android & iOS). The different app stores act as oracles of the smart contracts, which are associated with each of the platform’s core transactions. This system creates a trust layer for the economy, obviating the need for intermediaries. AppCoins aims to become the universal language of the app economy.

The protocol also includes a so-called Proof-of-Attention system. Users, app stores, and OEMs receive tokens through the Proof-of Attention concept as a reward. Developers that want to advertise their apps can be sure that the user has installed and used it. The users reinvest their tokens via inapp purchases and this would theoretically create a virtuous loop that boosts the AppCoins economic growth.
