As a small, independent Tezos blockchain validator, we play an important role in enhancing the network and preserving art.


Delegators earn passive income on the Tezos network by participating in our baking service. We receive rewards when selected to bake or attest, and we distribute these rewards to delegators after deducting a baking fee.

How to Delegate

Delegations can be made to our regular wallet address:
Delegations can also be made to our .tez wallet address:

  1. In the Temple browser extension wallet, scroll to the "TEZ" entry.

  2. If it is your first time delegating, select the blue "NOT DELEGATED" button, scroll to the bottom, select "DELEGATE", copy our wallet address noted above, paste it into the BAKER field, scroll down and select "DELEGATE".

  3. If you would like to select a new baker, select the blue "APY" button, select "RE-DELEGATE", copy our wallet address noted above, paste it into the BAKER field, scroll down and select "DELEGATE".

Baking Environment

Our baking environment consists of a room with regulated temperature and humidity, a high-speed wired internet connection, an Intel NUC (i5 processor, 32 GB RAM, 1 TB solid state drive), and 2 Ledger cold storage wallets. Two uninterruptible power supply units are in use: one dedicated to the high-speed wired internet connection and another dedicated to the Intel NUC.

Q: Which cryptographic curves does Tezos support?
A: Tezos supports three cryptographic curves, each identified by the prefixes 'tz1,' 'tz2,' and 'tz3' in the public key hash:
      ‘tz1’: Ed25519 elliptic curve
      ‘tz2’: Secp256k1 elliptic curve
      ‘tz3’: P-256 elliptic curve
These curves are integral to generating cryptographic key pairs within the Tezos blockchain, providing security and functionality to the network.


Q: What is the smallest monetary unit in Tezos?
A: 1 tez (or xtz) is divisible to six decimal places. The smallest unit is called a micro tez and is referred to as one_mutez in the protocol. So, 1 tez = 1,000,000 micro tez. Learn More ➜
Q: As a Tezos baker, how can I keep track of rewards after payments?
A: Bakers can use this formula: ((stakingBalance - bakerBalance) / (stakingBalance) * receivedRewards * bakerFee). The bakerBalance is equal to (stakingBalanceMutez - delegatedBalanceMutez) / 1000000. Note how the balances are in mutez (1 tez = 1,000,000 mutez). See these balances in the API endpoint here ➜
Q: When processing payments, what does the error "subtraction_underflow" mean?
A: When processing payments, if you encounter a "subtraction_underflow" error, it may be due to a low balance in the wallet that processes payments. The Tezos Gitlab Errors page describes "Underflowing tez subtraction" as "a subtraction of two tez amounts underflowed (i.e., would have led to a negative amount)."
Q: Why aren't my profiles on and showing the latest version of my baking software?
A: After an upgrade to baking software, profiles on and will be alerted to fact of the software upgrade the next time your validator is chosen to add a block to the blockchain because the information is included in the block.


Q: What are the repercussions of overdelegation?
A: Reward dilution. If our service is overdelegated by 1%, our service (and all delegators) will get 1% less than the amount we would have received if not overdelegated. Learn More ➜
Q: What is the annual energy consumption and electricity cost for a Tezos baker?
A: Baking environments vary and energy costs vary throughout the world. As an example, we use an Intel NUC (i5 processor, 32 GB RAM, 1 TB solid state drive). Our annual energy consumption is 78.84 kWh/year and the electricity cost per kWh is approximately $0.25 USD. So, our annual electricity cost is approximately $20.00 USD.
Q: Which layer 1 blockchains use formal verification and why is it important?
A: Tezos, Cardano and Algorand use formal verification. Formal verification techniques enhance security and reliability. On Tezos, developers verify the correctness of their code mathematically which mitigates potential vulnerabilities and ensures integrity of the protocol. Learn More ➜
Q: How or when is a delegator's amount of delegated XTZ noted for a given cycle?
A: The node takes 16 snapshots per cycle (every 512 blocks) and then, when a new cycle starts, it uses a randomly-selected one of those 16 snapshots of delegated XTZ. Learn More ➜
Q: If the validator computer is undergoing maintenance and attestations are missed, will delegators miss out on attestation rewards?
A: More than likely not. Validators need at least 67% of the attestations to go through to get the full cycle reward. We would have to be offline for more than 33% of our attestations to miss out on attestation rewards. Learn More ➜


Q: What are some important dates related to art in the Tezos ecosystem?
A: See the table below. As a reference, the Tezos blockchain (mainnet) launched on September 17, 2018.
