Academic Research

Explore our research on Blockchain interoperability

One of the Pantos project’s core goals is to contribute to the scientific community and build a mutual knowledge base.

Bitpanda itself has employed multiple researchers who are well-respected in their field. Besides that, our CDL-BOT partnership with the TU Hamburg and the TU Wien also leads to regular publications in the field of blockchain interoperability and other research fields related to distributed ledger technologies.

Technical Whitepaper 10

In this white paper, we present a framework enabling cross-blockchain smart contract invocations between Ethereum-based blockchains. With just two lines of code, developers can invoke smart contracts deployed on other blockchains, e.g., they can deploy a contract on the Ethereum...

Technical Whitepaper 9

In this paper, we present extensions for a cross-blockchain token transfer protocol to ensure that tokens in transit are eventually recreated on the destination blockchain and to provide transfer confirmations on both blockchains involved in the transfer in a fully decentralized manner. Further, we...

Technical Whitepaper 8

In this paper, we further reduce operating cost of our existing blockchain relay solution by applying the content-addressable storage pattern. Furthermore, we outline how relays can be leveraged to enable blockchain interoperability applications such as cross-blockchain token transfers...

Technical Whitepaper 7

In this paper, we develop an incentive structure for blockchain relays that follow a proof on demand approach where block headers are optimistically accepted and only fully validated if identified as illegal by off-chain clients. The preliminary cost analysis shows that such blockchain relays are able to...

Technical Whitepaper 6

In this paper, we describe concepts that enable the verification of transactions across blockchains in a trustless and decentralized manner. These concepts can be used as foundation for enabling decentralized applications such as cross-blockchain token transfers.

Technical Whitepaper 5

Interoperability between blockchains remains an open problem, with current interoperability approaches providing very limited means of cross-blockchain interaction, mostly in the form of atomic swaps. More general means of blockchain interoperability such as cross-blockchain data exchange, including...

Technical Whitepaper 4

In this paper, we review the current state of the art in the field of cross-blockchain technologies, including our own work within the TAST research project, answer former open questions from today’s perspective, and give an outlook of current challenges and possible future work.

Technical Whitepaper 3

In this white paper, we address existing challenges of this concept. We present a way of creating cryptographic Proof of Intent for cross-blockchain asset transfers, and propose the concept of deterministic witnesses, a solution for assigning witness rewards in claim-first transactions. This work supports the implementation...

Technical Whitepaper 2

This white paper formalizes the cross-blockchain proof problem, showing that in practice, it is not possible to verify the existence of specific data on one blockchain from within another blockchain. Based on this, we describe the concept of a cross-blockchain asset transfer protocol using claim-first...

Technical Whitepaper 1

This paper reviews the current state of the art, both in terms of blockchains and atomic swap technologies. More specifically, we survey twenty of the most prominent blockchains, as well as fourteen currently operational or forthcoming cryptocurrency systems, discussing their features and potential...
