Just wonder if a single Corda node can support multiple accounts like Bitcoin does.
A related open question I found on discourse https://discourse.corda.net/t/can-you-have-a-corda-identity-adress-without-running-a-node/1298
From Peter FroystadFroystadP6d
Does Corda support multiple people having accounts/addresses on the network without running a Corda node? Similar to how Bitcoin allow people to own coins with a private key, but not running a full node?
In the financial world, this would correspond to people having an account in the bank, and they would share facts on a 1-1 basis with their bank regarding their dealings. These customers wouldn't run a peer node however. But they would want a service similar to a Bitcoin wallet that would allow them to access their dealings with the bank
回答1:
Corda is designed for varied institutions which are not all banks, so it doesn't have a direct concept of "account" like Bitcoin does. If you want to implement customer accounts on top of Corda you need to track the balances yourself and use Corda for inter-institutional transfers. Corda's ability to easily integrate with SQL databases and MQ makes that kind of integration quite easy though.
If you're asking about multiple identities on a single node, so one machine can do both legal entity A and B at once, the answer is: we're working on it.

According to the blog post by Mike Hearn: https://discourse.corda.net/t/mobile-consumer-payment-experiences-with-corda-on-ledger-cash/966
Note that your balance in this scheme is simply your bank balance. There are no separate wallets.
It looks to me running multiple accounts/parties on a single node is not supported in the moment. Yet, we may expect the support realized in Phase 2 Bitcoin SPV wallet mode.
In phase two this is extended to support a model more like Bitcoin SPV, whereby the sending device manages its own private keys and transaction data. It thus becomes a true wallet app.

It is now possible with Corda 4.3 and the new Accounts SDK
https://github.com/corda/accounts
However, it is not a simple drop in replacement for Party and requires changes to an existing cordapp and implementing several parts of the business logic of what you might consider an "account" or "wallet".
