    Hello All Again. Still working through the example ATestConsumer contract with my node. I am still getting 0 wei returned when running the requestEthereumPrice. My node address is: 0x3De19A3ee2dd348E7045733D9b01c373CFf9dbD3, and it has a balance of 1 eth on ropsten. The transaction from the request is: https://ropsten.etherscan.io/tx/0x486c9621ce3a1a11be08dbebd5c82c071ba246f8ac3c76d07a940c6b1d300b89. Node address: https://ropsten.etherscan.io/address/0x3de19a3ee2dd348e7045733d9b01c373cff9dbd3, and still 0 transaction run on my node. Any ideas where I should look?

    Hello I keep getting "CheckAttempt GetTxReceipt failed: Bad response on request: [ TransactionIndex ]. Error cause was EmptyResponse," errors with my jobs on Ropsten. Anyone else?
    Bryce Blilie
    ^^ switched from Linkpool to Fiews, error went away - no other changes. I saw hints of this in the above conversations regarding using a Light Client. Thanks!

    @thodges-gh Finally sorted out my issue. I confused ORACLE_CONTRACT_ADDRESS with ACCOUNT_ADDRESS, even though it's mentioned in the docs. The real issue must be my multi-tasking. I am not seeing much activity here lately. Is that normal?
    There are phases, I'd say.
    I have a chainlink node running alongside geth and I cannot figure out how to send an erc20 token to another account the curl command looks like this and returns body=FAILED TO READ BODY
    'curl -b cookiefile -H "Content-Type: application/json" -d '{raw: "0x0",tx: {gas: "0x0", gasPrice: "0x0", hash: "0x0", input: "0x0", nonce: "0x5c7", r: "0x0", s: "0x0", to: "0x0", v: "0x0", value: "0x0"}}' http://localhost:8545/v2/transactions/0x0
    curl -b cookiefile -H "Content-Type: application/json" -d '{raw: "0x0",tx: {gas: "0x0", gasPrice: "0x0", hash: "0x0", input: "0x0", nonce: "0x5c7", r: "0x0", s: "0x0", to: "0x0", v: "0x0", value: "0x0"}}' http://localhost:6688/v2/transactions/0x0
    any other attempt returns 401 error not authorized, how do I set the API login information? Do I have to apply for it?

    I have a chainlink node and a quorum local node running, I could create a job and had successful job executions that hit sample API for 0.4. solidity version contracts, however as I used 0.5 version solidity chainlink contracts , the chainlink-node fails to parse the tx logs

    I cannot work with 0.4 version contracts as all our contracts are 0.5, been stuck with this for a week, any help is appreciated. thanks in advance

    Hello, I'm trying to deploy a TestConsumer contract to Ganache via Remix but I get this error:

    Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
    "message" must be a nonempty string.

    It deploys on Ropsten without any problems. Would there be a difference between Ropsten network and Ganache? I've also set my hardfork version to byzantium
    The code I'm trying to compile is this https://raw.githubusercontent.com/smartcontractkit/chainlink/master/examples/testnet/contracts/TestnetConsumer.sol

    @thodges-gh how do nodes get added to the reference contract?

    Hi - I just created a bitcoin adapter for Chainlink. So far it supports querying the current block number but I will soon implement other functionality like querying transactions and addresses. https://github.com/acoutts/chainlink-bitcoin-adapter
    Good work! Let's move technical discussion to our Discord, here: https://discord.gg/aSK4zew
    You'll be able to reach more node operators and developers there.
    It seems Ropsten' ETH/USD Aggregator contract has been redeployed at 7th of Jan. So, the services using old version at 0x0Be00A19538Fac4BE07AC360C69378B870c412BF should update the aggregator address to 0x8468b2bDCE073A157E560AA4D9CcF6dB1DB98507. Also naming of variables has changed, now the price is stored in 'latestAnswer' variable, not in 'currentAnswer'.
    But actually it updates very slowly, last update has been performed about 30 hours ago. Is it possible to speed up updating?
    Can we expect redeployment of Mainnet contract?

    Hi folks, am I right in understanding that buildChainlinkRequest()/sendChainlinkRequest() implements a callback, so computation of my Solidity contract will not proceed until the job has been fulfilled?

    e.g. if I take the requestEthereumPrice() example in the docs, and do this:

    uint256 x = currentPrice;
    uint256 y = currentPrice;

    will x and y have different values (assuming the price changes in the time between requests)?

    Hi everyone, I dont see my LINK balance ever increasing even tho I have successful job runs. Will it change?
    The LINK is going to the contract and currently is not visible on the node operator console.
    The Discord is more active for node operators if you want to join us there.

    Hello Guys.
    I'm trying to use 'Sleep' adapter but requests executes immediately without deley.

      address _oracle = 0xA3Ce768F041d136E8d57fD24372E5fB510b797ec;
      bytes32 _jobId = "00364325dafb410bbdadd7d79e69eab5";
      function _requestSobr(uint delay) private {
        Chainlink.Request memory req = buildChainlinkRequest(_jobId, this, this.fulfill.selector);
        req.addUint("until", now + delay);
        req.add("get", "https://api.loanscan.io/v1/reference-rates/current/Sobr?tokenSymbol=DAI");
        req.add("path", "DAI");
        req.addInt("times", 100000000);
        sendChainlinkRequestTo(_oracle, req, LINK);

    I found an accepted bug, does it works today or am I doing something wrong?

    Hi all. I'm looking at implementing an ETH:USD price feed in my Ethereum dApp via the Chainlink Aggregator template.

    I hear Chainlink prices are updated every 10 minutes. Are oracles synchronized with their price updates, or do they update on their own schedules? I'd like to ideally minimise gas and only request a new price when oracles have updated their data.

    I have some very basic question to determine if I am in the right place. I am looking for decentralised Oracles to feed USD/BTC prices to a smart contract. Does chainlink work with many blockchains or just Ethereum? The prices need to be every second.
    How do I get the 0.5.0 solidity version of the Chainlink contracts from NPM? thanks
    Verified the truffle box is working with 0.5.0 contracts. There appears to be an issue with my "fund-contract.js". I will have a look at this later.

    Hey guys! Two quick questions:
    1 - are there any research grants available for Chainlink?
    2 - are there any in-depth docs available other than whitepaper, official docs and codebase? Especially about the aggregating process on-chain and/or external adapters. Is there a way to get in touch with someone from inside Chainlink to discuss further details - I'm doing research in that area. Would also be great to know which parts of the whitepaper are still valid - e.g. there is a part about Chainlink's goal to combine Trusted Execution Environment in this aggregation process.

    hey hey. i'm trying to use the tutorial for ropsten, but when I put in the jobid "897479ba429445e4a89be90cfcd52a51", it complains that it isnt a bytes32

    for this function:
    function requestEthereumPrice(address _oracle, bytes32 _jobId, uint256 _payment)

    Has anyone ran into this before ?

    (ill put it in the discord too)

    Hi guys. Can someone help me? i am trying to run chainlink node for first time and i get this error: " unable to initialize ORM: PQ: syntax error at or near "NOT error runing migrations"

    Hi Guys,

    I use Chainlink to request data and then save it in a local variable. This variable is then assigned to an array. Unfortunately the data assignment to the array is not synchronous, because I get the result from Chainlink a bit later.
    What can I do so that only when I receive the data from Chainlik, is it assigned to the array?

    Hi team. Might be worth adding to the docs that for the "DATABASE_URL=postgresql://$USERNAME:$PASSWORD@$SERVER:$PORT/$DATABASE" line to connect to the db, it should have "?sslmode=disabled" at the end (no space) for anyone running a local docker postgres image.
    Otherwise there will be a "unable to lock ORM: pq: SSL is not enabled on the server" error
    Additionally the docs say to set ETH_CHAIN_ID to 3 but my geth image defaulted to 0. Something to be aware of/make note of.
    On ropsten btw, I realize the IDs will be different between networks. My ropsten was 0. Started with:
    "docker run --name eth -p 8546:8546 -v ~/.geth-ropsten:/geth -it \
    ethereum/client-go --testnet --ws --ipcdisable \
    --wsaddr --wsorigins="*" --datadir /geth"
