What is Blockchain-on-Blockchain?

Blockchain-on-Blockchain (BOB) is a new blockchain built on top of another blockchain called ICP. It’s like a special layer on an existing system. BOB creates a secure digital record book that uses ICP’s network for safety.

How does BOB work?

BOB uses a system called ‘proof-of-on-chain-work’:

• You deploy your own smart contract (canister) at bob.fun.
• This program solves math problems (hashes).
• Main computers (mother nodes) give out these problems.
• Miners solve the problems and tell the mother node.
• If correct, the mother node adds a new block to the blockchain.
• The winning miner gets BOB tokens as a reward.

Initial parameters

• Block reward: 600 BOB
• BOB supply: 21 million
• Halving: Every 17’500 blocks
• Halving expected every 24 days

Mining details

At the current speed of 6B hash/s, and with 1000 miners, the average time to mine a block is 2 minutes. There’s no limit on the number of miners. Miners are chosen by the mother node after paying a fee.

Costs and speed

• On ICP, $1 buys 1T cycles (fuel for the program).
• A miner’s program uses 1T cycles per day at full speed.
• Miners choose their speed, affecting daily solved problems.
• Each message contains 6,000,000 solved problems.
• If a miner’s program runs out of cycles, it stops until refueled.
