Re: How to handle changing public IP address on the node for personal user

David Awad
 

Hey paulo, for future reference, try to use #general on slack.corda.net as it's a much faster way to get answers and input on questions. 

That being said, for a personal use case you're better off using the network bootstrapper when working locally. Don't think about the IP address at all. 

 

Normally what you'd need to do is setup a network map server, we normally recommend you use corda enterprise network manager or cordite to do so. 

 

Hopefully this helps.

Hello Guys, 

 

as this topic was ended couple years ago, also i am new at the Group, i would like to know if a more recent market suitable solution for this is in place?

 

Regards, 

Paulo.

Thank you David,

Perhaps LeanState's scope is not enough for a blog post, but slack shares would be nice: more people, more bugs/feedback.

Cheers,

THIS is awesome, glad to see you're crushing the game out there. 

 

If you're interested we might be able to put together a blog post for the corda medium or maybe a slack share or two if you want this project to get some exposure. 

 

Thanks!

Hey Lan ,

 

You probably know this but, for thread's sake, Java8 support was brought back with CDM 2.116.0 and up, see https://docs.rosetta-technology.io/cdm/releases/all.html

Hi All,

I’d like to have some news about what has been already discussed in the following threads

 

Corda running on Java 9 - Stack Overflow

CORDA-2050 Upgrade Corda to Java 11 (compatibility mode) by josecoll · Pull Request #5356 · corda/corda · GitHub

 

More in detail, we are working on a solution built using Corda and ISDA CDM.

Because of the end of public support for Java 8 by Oracle since January 2019, ISDA CDM migrated to Java 11; this means that we are not able to use Corda and CDM together.

Are there any updates about how and, overall, when Corda will be compatible with the newer LTS version of Java? Will it fully compatible with OpenJDK version (see new licensing terms from Oracle)?

 

Thanks a lot

Lan

Lean State

Manos Batsis
 


Shamelessly lazy or simply tired of manually maintaining ContractState / PersistentState mappings? LeanState [1]  (re)generates perfectly synced and consistent state classes at build-time, based on simple model interfaces.


BTW if you have ideas for checking whether XML liquibase migration files are up-to-date at build time lemme know at https://github.com/manosbatsis/corda-lean-state/issues/1

I believe Corda 5 is aiming for end-of-year to be out to the masses. When it's out we'll certainly be vocal about it with the community.

Re: Token Design: Walking the transaction backchain vs Adding issuer as participant #Corda

David Awad
 

an answer I heard from Matthew Nesbit (within R3): 

 

>    I believe the work is the same whether issuer sees all changes as they happen, or only as it resolves backchain. Just that time span of the loading is different


Re: Corda Masterclasses

David Awad
 

thanks for the share! 


Token Design: Walking the transaction backchain vs Adding issuer as participant #Corda

Clyde DCruz
 

Since an essential part of the tokens lifecycle is redemption, does the regular approach of selective sharing of transactions + backchain resolution have any advantages over simply adding the issuer as a party to all transactions involving the token?

While designing a token, there are 2 available options:  

1. Don't keep the issuer as a participant to all transactions involving the token, issuer will need to verify the backchain during redemption
2. Keep the issuer as a participant to all transactions involving the token. 

Questions
1. In approach (1), does the issuer have to sift through less amounts of data as opposed to approach (2) ?
2. Does either approach have privacy / performance benefits over the other?

How to set permissions for the new CE4.6 RPC APIs?

Sean
 

Hi,
  CE4.6 added some new flow management APIs for RPC such as flowStatus queryFlows or queryById, flow pause or retry, etc. How do we set permissions in node.conf on them for RPC users? I tried InvokeRpc.flowStatus or InvokeRpc.queryFlows. That did not work.
  Please advise.
  Thanks.

Hi there,

 

I am putting together a course for blockchain security. For the Smart Contract-related Vulnerabilities chapter, we covered Ethereum and Hyperledger, yet we have nothing on Corda. So I was hoping to get more info on it. For instance, some subtopics covered are as below:

  • Access control
  • Default visibility
  • Reentrancy
  • Integer overflow and underflow

 

Any help would be appreciated.
