First build the Sawtooth Lake core using following command: $ /project/sawtooth-core/bin/build_all When the build has completed successfully, in order to run the transaction validator, issue the following commands: $ /project/sawtooth-core/docs/source/tutorial/genesis.sh This will create the genesis block and clear any existing data files and keys.
This command should show an output similar to the following screenshot: Genesis block and keys generation The next step is to run the transaction validator, and change the directory as shown follows: $ cd /project/saw-toothcore Run the transaction validator: $ ./bin/txnvalidator -v -F ledger.transaction.integer_key –config /home/ubuntu/sawtooth/v0.json Running transaction validator The validator node can be stopped by pressing Ctrl + C.
A Complete Guide to Understanding This Blockchain Concept
Once the validator is up and running, various clients can be started up in another terminal window to communicate with the transaction validator and submit transactions.
For example, in the following screenshot, the market client is started up to communicate with the transaction validator.
Note that keys under /keys/mkt.wif are created by using the following command: ./bin/sawtooth keygen –key-dir validator/keys mkt mktclient for marketplace transaction family This completes our basic introduction to Sawtooth.
$ vagrant ssh When the vagrant prompt is available, run the following commands. First build the Sawtooth Lake core using following command: $ /project/sawtooth-core/bin/build_all When the build has completed successfully, in order to run the transaction validator, issue the following commands: $ /project/sawtooth-core/docs/source/tutorial/genesis.sh This will create the genesis block and clear any existing data files and keys.

The example shown above is also quite basic but
Why This Matters for Blockchain Technology
Understanding $ vagrant ssh is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
Key Points to Remember
- Once the validator is up and running, various clients can be started up in another terminal window to communicate with the transaction validator and submit transactions.
- For example, in the following screenshot, the market client is started up to communicate with the transaction validator.
- Note that keys under /keys/mkt.wif are created by using the following command: ./bin/sawtooth keygen –key-dir validator/keys mkt mktclient for marketplace transaction family This completes our basic introduction to Sawtooth.
Conclusion
$ vagrant ssh represents one of the many innovative layers that make blockchain technology so powerful and transformative. As distributed systems continue to evolve, a solid understanding of these core concepts becomes increasingly valuable — not just for developers, but for anyone building, investing in, or working alongside blockchain-powered systems.
Whether you are just starting your blockchain journey or deepening existing expertise, mastering these fundamentals gives you the tools to think clearly about decentralized systems and make smarter decisions in this rapidly evolving space.
