Gateways Module Tutorial

Tutorial

In this tutorial, we will create a gateway that can serve to represent KMD. The following are the steps in the gateway-creation process:

Create a new Smart Chain and provide representative tokens
Prepare a special oracle to monitor Komodo's chain state
Bind the tokens and the oracle to our gateway
Deposit KMD into the gateway
Exchange tokens with other tokens on-chain
Use the tokens to withdraw KMD

Please ensure that you have the KMD main chain downloaded and synced before continuing further in the guide.

Also, please open an empty text file and save all output transaction ids and hex-encoded data from each step. You will need the information at various stages.

Manually Compile and Install Komodo From Source

For this tutorial, please compile and install Komodo software from the source repositories.

Information on manual installations can be found at this linked documentation.

Create a New Blockchain

For this tutorial we will create a temporary Smart Chain called HELLOWORLD for educational purposes.

Make sure that the total ac_supply of this Smart Chain is fairly large. 777777 coins will do for our purposes.

Follow these linked instructions before continuing.

Recall also that a user must have a pubkey enabled when interacting with an Antara-related Smart Chain. View this linked material for an explanation.

If desired, the reader may use an existing Smart Chain instead of a temporary educational chain. Follow this link for a list of smart-chain launch parameters.

Create a Token to Represent an External Cryptocurrency

For the GatewaysCC module to function it must have access to tokens that can represent an external cryptocurrency. We use the Tokens CC module to this effect.

Decide the Number of Tokens to Create

We want the number of total tokens to be the maximum possible amount of the represented cryptocurrency that we expect to hold.

Each token is created not from a full coin, but rather from a satoshi.

For example, 1 HELLOWORLD coin creates 100000000 tokens.

The HELLOWORLD satoshis should pair on a one-to-one basis with KMD satoshis.

For our purposes, we will use 1000 coins of HELLOWORLD.

Creating the tokens

To create the tokens, execute the following command:

./komodo-cli -ac_name=HELLOWORLD tokencreate KMD 1000 KMD_equivalent_token_for_gatewaysCC

This creates a 100000000000 token supply of on-chain tokens with the name of KMD, which represent the external cryptocurrency, KMD.

For more details on the above command, see tokencreate.

This command returns a hex value as a response:

{
  "result": "success",
  "hex": "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" } ```

Select the hex value (01000000022c223c...) and copy it (CTRL + SHFT + C).

Broadcast this value using sendrawtransaction:

./komodo-cli -ac_name=HELLOWORLD sendrawtransaction insert_hex

This returns a string, and this string is our tokenid.

315d16c2dddd737f8a48f81499908897b53d05d20fb1344e349e304fb603f6bf

Copy the tokenid into the text editor we opened at the beginning of the tutorial and keep it available for future use.

Watch the mempool using getrawmempool to verify that the tokenid is successfully mined:

./komodo-cli -ac_name=HELLOWORLD getrawmempool

Once the tokenid disappears from the mempool the transaction is mined.

If this Smart Chain were receiving full dPoW security services, at this point it would be appropriate to wait for notarization. We can use getinfo to watch for the notarizations property to increase:

./komodo-cli -ac_name=HELLOWORLD getinfo

On this educational Smart Chain, however, we can continue without waiting for notarization.

We can check to see that our token is successfully created on the chain using tokeninfo

./komodo-cli -ac_name=HELLOWORLD tokeninfo insert_token_id

We can check the balance of our pubkey using tokenbalance:

./komodo-cli -ac_name=HELLOWORLD tokenbalance insert_tokenid insert_pubkey

Create an Oracle

We use the Oracles Module to add external data to the blockchain.

The name of our oracle should be identical to the name of our tokens, KMD, and the data format must start with Ihh (height, blockhash, merkleroot):

Create the oracle using oraclescreate:

./komodo-cli -ac_name=HELLOWORLD oraclescreate KMD blockheaders Ihh

This returns a hex value:

{
  "result": "success",
  "hex": "010000000185b76ed0fbdb9ee2bdb5693f491b6ea23de6498f42c6e83f9f36c1eaf411dd990200000049483045022100aa198a2ae959ee191e1359df48867480bf5a1a5bd4fa76b4398481c89ff3095102205034824dcd56b312183acd65c27a002a13dae84f5d22c767f1efaae09ef63a5c01ffffffff0310270000000000002321038c1d42db6a45a57eccb8981b078fb7857b9b496293fe299d2b8d120ac5b5691aac378740a804000000232103810d28146f60a42090991b044fe630d1664f3f8f46286c61e7420523318047b5ac00000000000000001c6a1aec43064e5957544852014c0e5765617468657220696e204e594300000000"
}

Broadcast the returned hex data using sendrawtransaction:

./komodo-cli -ac_name=HELLOWORLD sendrawtransaction insert_hex_data

This returns a transaction id, which is the oracleid:

0df7c4d844f08dba08abd4bb174558739f17cfe268feb005fb6333b3761d9203

Record this in the text editor.

Before registering as an oracle publisher, we need to run the oraclesfund method:

./komodo-cli -ac_name=HELLOWORLD oraclesfund 7b6e7745058ffded423546eecc61dcc05069279b90776384c52692765246b64c

Send the raw transaction by broadcasting the hex value:

./komodo-cli -ac_name=HELLOWORLD sendrawtransaction 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

Response:

(Use ./komodo-cli -ac_name=HELLOWORLD getrawmempool to ensure that the transaction receives confirmation.)

To prepare for the oraclefeed instance, use oraclesregister to register as a publisher for the oracle. This must be done on a node which can post KMD block headers and which can execute withdrawal transactions:

./komodo-cli -ac_name=HELLOWORLD oraclesregister insert_oracleid data_fee_in_satoshis`

This returns a hex value (not shown for brevity), which we now broadcast:

./komodo-cli -ac_name=HELLOWORLD sendrawtransaction insert_hex_value

Retrieve the data publisher's pubkey using oraclesinfo:

./komodo-cli -ac_name=HELLOWORLD oraclesinfo insert_oracleid

The property, "publisher", in the entry, "registered", of the returned json object is the data publisher's pubkey, also called the publisherpubkey.

Subscribe to the oracle using oraclessubscribe to receive utxo information for data publishing.

The frequency of data-publishing transactions we can perform in a block is equal to the number of active subscriptions committed to the oracle. Therefore, we must have at least one subscription for the oracle to allow publishing.

./komodo-cli -ac_name=HELLOWORLD oraclessubscribe insert_oracleid insert_publisherpubkey insert_amount_of_funds_to_add

This returns a hex value (not shown for brevity), which we now broadcast:

./komodo-cli -ac_name=HELLOWORLD sendrawtransaction insert_hex_value

Execute the oraclessubscribe and sendrawtransaction methods several times and with the same amount. This gives us the opportunity to broadcast more than one sample of data per block. In our example, we want to publish data for more than one KMD-height per block.

Verify the oracle information to ensure it is properly established:

./komodo-cli -ac_name=HELLOWORLD oraclesinfo insert_oracleid

Activating Gateway Binding

We now create a gateway and bind our information to it, using the gatewaysbind method.

This method requires that we decide how many total gateway signatures we desire (N), and how many signatures are required to withdraw funds (M).

For our educational example, we may set both N and M equal to 1, for simplicity.

As a part of this command we will need to indicate the pubtype, p2shtype, and wiftype values for our chosen coin. For KMD, these values are 60, 85 and 188 respectively.

./komodo-cli -ac_name=HELLOWORLD gatewaysbind insert_tokenid insert_oracleid KMD insert_tokensupply 1 1 insert_gatewayspubkey 60 85 188

This method returns a hex value (not shown for brevity), which we now broadcast:

./komodo-cli -ac_name=HELLOWORLD sendrawtransaction insert_hex_value

The broadcast returns a transaction id, also called the bindtxid. Copy this information into the text editor.

Assuming everything is properly created and executed, we may now review our new gateway using gatewaysinfo:

./komodo-cli -ac_name=HELLOWORLD gatewaysinfo insert_bindtxid

Use the returned information to verify that the tokenid and oracleid match the information in our text editor.

Assemble an Oracle Instance

An oracle instance automates the transfer of merkleroot data to our oracle. The Komodo software suite includes built-in tools for creating an oracle instance.

Change into the correct directory (this command assumes we installed Komodo in the default directory):

cd  ~/komodo/src/

Compile the instance:

gcc cc/dapps/oraclefeed.c -lm -o oraclefeed

Run the instance:

./oraclefeed HELLOWORLD insert_oracleid insert_mypubkey Ihh insert_bindtxid &

Using the Gateway

With our gateway created and our oracle instance running as a background process, we are finally prepared to test our gateway.

First, we need the gatewaysDepositAddress. This is the address where we will deposit our KMD on the main KMD chain.

./komodo-cli -ac_name=HELLOWORLD gatewaysinfo insert_bindtxid

The deposit property contains the gatewaysDepositAddress. When we send funds to this address, we receive in return HELLOWORLD KMD tokens to an on-chain address that we indicate as follows.

Use the z_sendmany method to send funds to two addresses simultaneously. The first address is the normal address for the pubkey that corresponds to our pubkey on the HELLOWORLD Smart Chain which will receive tokens. The second address is the gatewaysDepositAddress on the KMD chain. We send a nominal amount into the first address, and the amount we wish to have available for trading into the second address. This is done on the external chain -- in this case, KMD.

./komodo-cli z_sendmany "insert_address_where_KMD_funds_are_currently_held" '[{"address":"addressOfPubkeyForTokenizedKmd","amount":0.0001},{"address":"gatewaysDepositAddress","amount":0.1}]'

The returned string is the operation_id. Use this with the z_getoperationstatus method.

./komodo-cli z_getoperationstatus '["insert_operation_id"]'

Execute this every few seconds until the status property reads success. Once this occurs, find the txid value. This is our cointxid, and we copy this into our text editor.

Wait for the transaction to be mined. Once confirmed, execute the gettransaction method with the cointxid to obtain more information we will need later.

./komodo-cli gettransaction insert_cointxid

Via the returned information from the gettransaction method, we can verify the addresses were correct by looking at the vout properties. At the bottom, there is a hex value. Copy the value to the text editor for later.

In the returned results there is also a blockhash value, which we can use to find out the height of the block which contains the cointtxid by using the method below.

./komodo-cli getblock insert_blockhash | jq '.height'

Next, execute the following command for more information:

 ./komodo-cli gettxoutproof '["insert_cointxid"]'

This returns a proof value. Transfer this to the text editor.

We now have the necessary data to execute the gatewaysdeposit method on the HELLOWORLD Smart Chain.

The gatewaysdeposit method broadcasts the relevant data on the Smart Chain so that the gateway nodes may validate the information and prepare to distribute the KMD tokens.

Here is the information we need for this call:

BINDTXID: our bindtxid
HEIGHT: the height value of the blockhash containing the cointxid transaction
COIN: KMD for this example
COINTXID: the cointxid returned from z_sendmany
CLAIMVOUT: the vout of the claim (this value should be 0, as it is our first use)
DEPOSITHEX: the hex value that is found by executing gettransaction on the cointxid
PROOF: the proof value returned after executing gettxoutproof on the cointxid
DESTPUB: the public key where the KMD tokens should be received on the Smart Chain (the same pubkey used earlier to retrieve the first address for the z_sendmany method)
AMOUNT: the amount of the deposit (in this case 0.1)

./komodo-cli -ac_name=HELLOWORLD  gatewaysdeposit BINDTXID HEIGHT COIN COINTXID CLAIMVOUT DEPOSITHEX PROOF DESTPUB AMOUNT

Successfully executing this command will return a hex value.

Broadcast the hex data:

./komodo-cli -ac_name=HELLOWORLD sendrawtransaction insert_hex_data

The broadcast returns a transaction id. Copy this to the text editor. It is the deposittxid.

For the deposit to process successfully, the oraclefeed instance must first process the block height of the z_sendmany transaction through the oracle

Claim the Funds on the Smart Chain

To claim the funds we must spend the marker and the deposit asset, and perform the claim.

This method is only available to the owner of the privkey corresponding to the pubkey used previously in the gatewaysdeposit method. The pubkey should be the -pubkey=$PUBKEY parameter used to launch the daemon.

BINDTXID: our bindtxid
COIN: KMD for this example
DEPOSITTXID: the transaction id returned from the gatewaysdeposit call
DESTPUB: the public key where these tokens should be received on the Smart Chain
AMOUNT: the amount of the deposit (in this case 0.1)

./komodo-cli -ac_name=HELLOWORLD gatewaysclaim BINDTXID COIN DEPOSITTXID DESTPUB AMOUNT

Broadcast the returned hex value:

./komodo-cli -ac_name=HELLOWORLD sendrawtransaction insert_hex_data

Once this transaction is successfully confirmed, the gateway will credit tokens to our indicated pubkey. These tokens are now usable as regular Token CC tokens.

For the claim to process successfully, the deposit and bind transaction must be confirmed first. This requires either 101 confirmations, or if the chain has dPoW, 1 notarization.

Withdrawing KMD Funds

When finished with our tokens, we may send them to the gateway and withdraw the corresponding KMD funds via the gatewayswithdraw method. Only the current owner of the KMD funds may execute the gatewayswithdraw method for these funds.

Recall that for the gateway to function, the oracle instance must be running.

Before we execute gatewayswithdraw, we must first import the private key for the gatewaysdeposit address on node which has oraclefeed instance running (this is needed only once).

Find the gatewayDepositAddress in the deposit property of the returned values of the following command:

./komodo-cli -ac_name=HELLOWORLD gatewaysinfo insert_bindtxid

Find the private key returned from this command:

./komodo-cli -ac_name=HELLOWORLD dumprivkey insert_gatewayDepositAddress

Execute the following commands on the node running the oraclefeed instance:

./komodo-cli importprivkey "insert_private_key" "label" false

Information for the next command:

BINDTXID: our bindtxid
COIN: KMD for this example
WITHDRAWPUB: the pubkey where the withdrawn coins should appear on the external chain; in this case, the KMD pubkey
AMOUNT: the amount to withdraw

./komodo-cli -ac_name=HELLOWORLD gatewayswithdraw insert_bindtxid KMD insert_withdraw_pubkey insert_desired_withdraw_amount

Once executed, the remaining portion of the withdrawal process should happen automatically.

Congratulations, you have successfully completed the cycle of the Gateways CC module.
