            How to sum values including entities with missing attributes on Datalog/DataScript/Datomic
            Asked 2021-Jun-14 at 13:00

            I'm learning Datalog/DataScript/Datomic. For this I've setup a simple ledger database on DataScript to play with. By now it basically consists of a set of accounts and a list of records with the attributes :entry.record/account and :entry.record/ammount. Now I'm trying to get the balance of all the accounts, by summing all the :entry.record/ammount for each account. This query gives me the balance for all the accounts that have records on the ledger:

            Datomic's Datalog is definitely uncomfortable for this sort of aggregation; my recommendation is indeed to use or-join so as to emit a zero amount:

            I am curious what database you are using that requires ODBC and does not have a specific provider.

            I have divided your code into user interface code and database code. This makes it easier to maintain.

            Database objects like Connection, Command, and DataReader must be closed and disposed. Using...End Using blocks take care of this even it there is an error.

            You can pass the CommandText and Connection directly to the constructor of the Command.

            Don't hold the connection open while you update the user interface. Comparatively, this is a long process and too long to keep a connection open

            This doesn't make any sense. You are resetting the DataSource to the same value numerous times. But, it won't work anyway because a DataReader is not a valid DataSource.

            QUESTION

            Is QLDB compatible with the Outbox Pattern?
            Asked 2021-Jun-01 at 22:03

            I have a use case for which QLDB makes the most sense. I also think the Outbox pattern makes sense for data reliability. However, I am worried about polluting the Journal with the outbox entries.

            My understanding is that while I can have my 'outbox' table separate from my main data table, the journal is shared across the entire ledger. It seems that the outbox pattern traditionally uses a relational DB where the concept of an immutable journal just isn't a concern.

            Is this going to be a problem as the data set grows? More so, is there an alternate pattern that would make more sense to use?

            ...

            ANSWER

            Answered 2021-Jun-01 at 22:03

            Since the journal is an immutable history of every transaction ever committed to the ledger, if you use the Outbox pattern with QLDB, your ledger will contain a permanent history of messages that passed through your Outbox table. This is great if you need an unfalsifiable audit history of the messages queued for sending and a record of them being sent ("deleted" from the table). However, if you don't need that, then you'll be paying storage for those messages for the life of the ledger and not getting much value from it.

            The typical event-driven approach would be to use QLDB's streaming feature, which associates a Kinesis Data Stream to your ledger. Every time you commit a transaction, QLDB will publish the transaction to the Kinesis Data Stream. This enables you to drive events from transactions occurring in your ledger. With this approach, you commit your business data to the ledger without worrying about the Outbox table. The document should contain the information you would need in your messaging. Upon commit, QLDB pushes the document(s) from the transaction into Kinesis where you process it using a Lambda function that sends the message onward.

            One thing to note is that QLDB offers an at-least-once guarantee of delivering data into Kinesis. This means that you'll need to identify and handle (or just tolerate) potential duplicate messaging. You should always be thinking about idempotence in distributed systems anyway, though.

            If you don't want to pay for Kinesis and don't need a real-time approach, there are things you can do with scheduled QLDB exports into S3 and some batch processing of the export files, but I'd start with streaming. DM me if you want to hear more about the export approach.

            How to create a fixed token and store the state information on the ledger in corda?
            Asked 2021-Jun-01 at 05:08

            I am new to corda token sdk. I want to create a cordapp for creating and selling tickets and are non-fungible. How do I store the ticketToken on the ledger?

            ...

            ANSWER

            Answered 2021-Jun-01 at 05:08

            In case the ticket is not replaceable by others of the same type (e.g. concert ticket) you would need a NonFungibleToken. To build a very basic one you would need to do the following steps:

            • create a state YourState that extends TokenType (or implements ContractState, if you need to have a contract associated with the state that can be verified with the transaction)
            • create a var issuedTokenType = IssuedTokenType(ourIdentity(), YourState). An IssueTokenType associates a TokenType with an Issuer party
            • create a var nft = new NonFungibleToken(issuedTokenType, holder, UUID) this creates a Non-Fungible Token issued by Issuer with holder (a Party) as a receiver
            • issue the token subFlow(new IssueTokens(listOf(nft)))

            There are many other ways, depending on what you need and how rich your State needs to be (it can be QueryableState, SchedulableState etc), and the token-sdk provides many helpers to help you create, issue and redeem tokens. All of them have their pros and cons, it depends on what you need to achieve.

            I suggest you go through the sources here below to learn how to use the token-sdk:

            With the above sources you will definitely be able to find everything you need to create and issue the type of token you need.

            If smart contracts are stored on blocks in the blockchain, how is its state updated?
            Asked 2021-May-18 at 13:14

            I understand that smart contracts are converted into bytecode and stored on a block in the blockchain. Smart contracts could be used similarly to Kickstarter. A project team might set a funding goal that would only be paid out if backers donate enough money to meet the goal.

            But how does the the smart contract know when to pay the project team? A block's hash changes wildly depending on its data. So, keeping track of the amount of donations and transaction IDs inside a block should not be possible because it would change the block's hash. Therefore, how does the smart contract know how much money has been funded, and how does it remember where to donations the money to if the funding goal is not met?

            Is it true that there is a ledger (or blockchain) and also a state database? If so, I'm assuming that we store values associated with a smart contract on the state database.

            ...

            ANSWER

            Answered 2021-May-18 at 13:14

            Bytecode of a smart contract is published in a transaction (that is mined in a block), and then stored in a storage of the network (usually Ethereum or Binance Smart Chain) associated with an address.

            So each time when you're interacting with a smart contract, you're interacting with an address that is associated with a storage chunk containing the bytecode. Plus the bytecode points to other storage slots where the values of its variables are stored.

            All state changes (including changes of the storage values) are part of the ledger database. The raw blockchain data only contain the state changes (not the current state), but most higher layers return the current state by default (you can still chose to fetch an older state, e.g. the "defaultBlock" param here). And some layers even disallow accessing previous states (e.g. Solidity and Vyper languages for writing smart contracts - you can compile this code to the bytecode).

            But how does the the smart contract know when to pay the project team?

            A smart contract can access current balance of any address, including its own. It can also have a variable containing the funding goal. Comparing these two values tells you whether the goal has been reached and whether the smart contract should pay the project team.

            However, smart contracts currently don't have any native timers (such as cronjobs) or event handlers - and functions are executed after a transaction is sent to the address of the smart contract (data field of the transaction states what function you want to execute and what arguments you're passing).

            So you need to either send the transaction (executing the withdraw() function) manually or using some offchain tool (that can watch the current balance and then send the transaction executing the function for you).
