-## **Interact with smart contracts via the OKP4 Explorer**
-
-A smart contract is a piece of code that runs on blockchain nodes, enabling automated and decentralized execution of programs. There are three types of smart contract interactions with Cosmos-based blockchains like OKP4. The OKP4 Explorer enables one to deal with all these operations:
-
-- **Instantiate:** This is the process of creating a new instance of a smart contract. It requires you to pay gas fees, as it involves computation and storage on the blockchain.
-- **Execute:** This is the process of running a smart contract function that changes the state. This could involve transferring tokens, updating variables, or triggering other contracts. Executing a function requires you to pay gas fees.
-- **Query:** This is the process of getting data from a smart contract. As it only reads the state, you don't have to pay gas fees when you query a smart contract.
-
-Consider the following smart contracts with the OKP4 blockchain:
-
-- `objectarium`, used to store unstructured data like Prolog programs
-- `law-stone`, used to manipulate rules (Prolog programs)
-- `cognitarium`, used to store structured data (ontology)
-
-To get all available methods and parameters, you can check the *msg.rs* file of each smart contract from the [OKP4 contracts GitHub repository](https://github.com/okp4/contracts). For example, you can retrieve [how to instantiate a `cognitarium`](https://github.com/okp4/contracts/blob/572a420d5414a86f31920e420861d0991656230d/contracts/okp4-cognitarium/src/msg.rs#L8C4-L8C4) and its [possible `Execute` messages](https://github.com/okp4/contracts/blob/572a420d5414a86f31920e420861d0991656230d/contracts/okp4-cognitarium/src/msg.rs#L16C1-L17C1).
-
-Below are examples of using a `cognitarium` smart contract. The approach is the same for other smart contracts.
-
-### Instantiate OKP4 smart contracts
-
-Anyone can deploy a new instance. Each smart contract is linked to a specific `CODE_ID`.
-
-|CODE_ID|Smart contract|Description|
-|-|-|-|
-|4|[`objectarium`](https://github.com/okp4/contracts/tree/main/contracts/okp4-objectarium)|Unstructured object storage|
-|5|[`law-stone`](https://github.com/okp4/contracts/tree/main/contracts/okp4-law-stone)|Source of rules|
-|7|[`cognitarium`](https://github.com/okp4/contracts/tree/main/contracts/okp4-cognitarium)|Structured object storage, ontology|
-
-Let's create a new database to populate the ontology, with a `cognitarium` smart contract instantiation (`CODE_ID = 7`).
-
-1. Click on the "Cosmwasm" tab to have the list of the available smart contracts. Click on the `CODE HASH` link next to `CODE_ID` `7`.
-
-
-
-2. Click on "Instantiate contract". Then a modal shows up. You see your OKP4 address in the "Sender" field. Set your OKP4 address as "Admin", and provide a unique name for the instance in the "Label" field. For the "Messages" field, you can set `{}` if you don't need to specify `limits` regarding store usage, or you can submit a configuration like the following:
-
-```json
-{
- "limits": {
- "max_triple_count": "1000000",
- "max_byte_size": "1000000000",
- "max_triple_byte_size": "999999",
- "max_query_limit": 30,
- "max_query_variable_count": 30,
- "max_insert_data_byte_size": "99999900",
- "max_insert_data_triple_count": "10000"
- }
-}
-```
-
-Then click "Send" and "Approve" when the Keplr window appears.
-
-
-
-3. Click on "View transaction" once executed to see all instantiation details. The transaction response from the JSON section gives you the resulting contract address. `okp41rprnv4g92cwhjsr226hkxzysxcsjgeh3llw0ps4wpuwsky4w38fq2gpy7z` is the instantiated address from [the `Instantiate` transaction](https://explore.okp4.network/OKP4%20testnet/tx/D132548E38BF942CEC242E1D380BC385335C4DC80DF68AEA37625C9C404A804E).

-
-4. The instantiated contract appears in the [contract list of `CODE_ID = 7`](https://explore.okp4.network/OKP4%20testnet/cosmwasm/7/contracts). We can see the `okp41rprnv4g92cwhjsr226hkxzysxcsjgeh3llw0ps4wpuwsky4w38fq2gpy7z` address:

You can only add it in a `cognitarium` contract you instantiated.
-
-1. The Turtle file data should be encoded in base64. You can use an [online tool](https://www.base64encode.org/), or you can use your terminal:
-
-```bash

-```
-
-2. Click on the "Execute" button for the `cognitarium` previously instantiated. Copy and paste the encoded data in the "Messages" field, following this JSON structure:

- "prefix": "core",
- "namespace": "https://ontology.okp4.space/core/"
- },
- {
- "prefix": "dataset",
- "namespace": "https://ontology.okp4.space/dataverse/dataset/"
- },
- {
- "prefix": "metadst",
- "namespace": "https://ontology.okp4.space/metadata/dataset/"
- }
- ],
- "limit": 2,
- "where": [
- {
- "simple": {
- "triple_pattern": {
- "subject": {
- "variable": "metadataid"
- },
- "predicate": {
- "node": {

## Recap'
- You can check any blockchain transaction details with an explorer.
- Transfer, delegation and governance operations are also possible with this type of user interface.
-- You can **instantiate** (deploy from code), **execute** a message (which modifies the blockchain state) and **query** (read request) a smart contract with the [OKP4 Explorer](https://explore.okp4.network/OKP4%20testnet). No need to [use your terminal with the CLI](https://docs.okp4.network/tutorials/cli-1), and you can more easily analyze transaction results.
-Explorers are powerful tools that allow you to interact with the OKP4 blockchain in a user-friendly way. Whether you're a developer looking to deploy and test smart contracts, or an end-user wanting to verify transactions, the OKP4 Explorer has you covered. So why wait?
