Hashgraph (formerly Swirlds Labs), the founder of the Hedera Hashgraph distributed ledger, is expecting to launch a permissioned DLT, HashSphere, in Q3. One of the current beta testers is Australia Payments Plus, which operates key Australian payment infrastructures and is a long standing governing council member of Hedera.
The DLT company sees a gap with the current permissionless and permissioned offerings. On the one hand, the challenge with permissionless chains for institutions is the need to repeat KYC and compliance steps that their clients have already done internally. Additionally, institutions want greater privacy and control. At the same time, many are looking for a path to interoperability with the permissionless world and stablecoins, an area where HashSphere is positioned as a good example.
There was much excitement when Australia’s eftpos joined Hedera years ago, with the hope of bringing regulated payments to DLT. Eftpos merged with other Australian payment infrastructures which are part of Australia Payment Plus. With stablecoins now on the cusp of going mainstream, perhaps that time has come. Hedera developed various solutions to make onboarding with stablecoins simple. Filipino banks plan to launch the PHPX stablecoin on Hedera this year.
Rob Allen from Australia Payment Plus commented, “As a Hedera Governing Council member, we are interested in HashSphere primarily for its enhanced privacy and regulatory compliance, while also needing network interoperability for the seamless and transparent interchange of stablecoins between public Hedera and private HashSphere, and other Layer1 protocols.”
HashSphere versus incumbent permissioned chains
The arguments about compliance, privacy and control are for those firms not comfortable with permissionless chains. But without additional details (which we don’t have yet), it’s less clear how HashSphere will compete with the existing permissioned chains, although we can make some guesses.
Hyperledger Besu is currently doing well in the institutional space because it offers a path to integration with the Ethereum mainnet. HashSphere can potentially compete because of its EVM (Ethereum) compatible smart contracts. Assuming HashSphere performs similarly to Hedera, it will have a speed and scalability performance advantage over Besu. HashSphere will use many of the features of Hedera, including its consensus, token service and the Ethereum compatible smart contract service.
However, both Besu and HashSphere have a disadvantage compared to some of the other permissioned DLTs on privacy. Canton and Corda were both designed as privacy first and only share data with those that need to know. It’s unclear whether HashSphere takes this approach, but we suspect not. So the options for Besu and HashSphere is Zero Knowledge Proofs or something similar. While that’s progressing, there is no definitive solution so far. For example, Brazil’s central bank wants to go this route with Besu, but is waiting for a solution that is good enough.
Digital Asset will argue that the Canton Network is permissionless, although we consider it a work in progress. We classify public Hedera as partially permissioned because the nodes with write permissions are still controlled by governing council members, although that is evolving. However, all transactions are viewable by anyone.
Hashgraph returns to its roots
In many ways, for Hashgraph this is a return to its roots. Hashgraph was previously known as Swirlds Labs, which started out with a permissioned ledger, including partnering with credit union startup CULedger in 2018. However, at the time Swirlds’ solution was not compatible with other technologies, whereas the Ethereum compatible smart contracts make it more open.
The news comes as the enterprise world seemed to be coalescing around three DLTs: the Ethereum compatible Hyperledger Besu blockchain, Digital Asset’s Canton, and R3’s Corda. Yet in the past week we’ve seen two new permissioned distributed ledgers, the other being Google Cloud’s Universal Ledger. On the one hand, fewer options make for simpler choices. But competition will keep the leading three on their toes.
