Hi Mohan, 

Here are our team's thoughts, but we'd love to hear the community's feedback as well.

In the short term we see the majority of interop and cross ledger communication happening at layer 2.  We are actively working with teams in the wider community to ensure that Besu facilitates layer 2 cross ledger communication, particularly working with the web3j team who are adding support for Hyperledger Fabric, and the Truffle team who are doing the same.

In the medium-term we are very interested in interoperability between chains, and we will be investing increasing effort in this direction, and in doing so expect to leverage many of the existing Hyperledger projects to do so. The two most obvious projects for collaboration currently are Burrow due to it’s EVM execution environment and aim of providing a practical base for EVM extensions in a many-chain world. In addition we look towards working with Quilt for its implementation of the interledger protocol. Quilt is a natural collaboration opportunity due to both the technologies it supports, and the fact that it is a JVM based technology.  

Thanks,

Grace

Thank you Grace, for the kind response

How do you foresee Besu converge with Hyperledger technologies. For example, do you see Besu converging or inter-operating with Fabric or Sawtooth anytime. I do see blockchain networks going Hybrid as they evolve. There are several other yperledger projects like URSA and Transact. Quite interested in knowing Besu leveraging these.

Thanks

Hi All,

Thanks for the thoughtful questions. We've responded to them below.

Virgil’s Question: 

Why the name "Besu"?  That seems an odd choice, I'd imagine you'd want to pick an Ethereum-related word like "Rainbow", "Unicorn", or some such.

PegaSys' Response:

As Dan mentioned, we had a trademark challenge with Pantheon and we have to switch our name regardless of the Proposal. We chose Hyperledger Besu because “besu” means base in Japanese. We felt like base indicated how we developed the Ethereum client. We believe it is a solid foundation for blockchain developers to work on to run networks, build applications or send transactions, as an example.

Hyperledger’s naming principles target names that are not “common” words and that are easy to trademark. Unicorn, rainbow and all other words we explored that have more direct connections to Ethereum will have trademark challenges.

Mohan’s Question: 

Hyperledger technologies support a permissioned blockchain. They do not, at least to my understanding, have a crypto aspect. Is the intent to incubate Besu as a permissioned ethereum based blockchain and support interoperability with other platforms like Sawtooth, Iroha , Fabric? Also, how does this relate to Hyperledger Burrow?

PegaSys' Response:
The intent for Besu to be submitted in its current form. It can be run on the Ethereum public network or on private permissioned networks, as well as test networks such as Rinkeby, Ropsten, and Görli. We think public chain compatibility aligns with the enterprise market’s growing interest in using mainnet for a broader and more diverse set of use cases. Because this project is a protocol, it can be used for many different applications. Enabling cryotocurrency is only one of the applications. This project would be the first public chain compatible client within Hyperledger.

Silas provides a great response on his thoughts about how the project relates to Burrow and some ideas around collaboration here. Burrow is most well known for its EVM, which could connect in with Besu. They have a number of other components that we have started discussing with Silas. We are excited about closely working with the Hyperledger community to find areas for interoperability across the other projects. We have ideas mentioned in the Proposal around who we can collaborate with. 

Thanks,

Grace

There were some trademark issues around "Pantheon", unfortunately

Hi All, We are excited to share that PegaSys, the Protocol Engineering team at ConsenSys, submitted the Proposal for our Ethereum client, Hyperledger Besu (currently known as Pantheon), for your consideration as a new Hyperledger project. 

We welcome your feedback on the Proposal and look forward to engaging with you on it. Feel free to send our team feedback via email or comment directly in the Proposal document.

Thank you,
