Blockchain
What is Blockchain?
A blockchain is a database that stores information in blocks, linked together in a chain. Each block contains a batch of transactions, and once a block is added, the data in it can't be changed without altering every block that came after it. This makes the record tamper-resistant.
The "decentralized" part means no single company or server controls the database. Copies exist across thousands of computers worldwide. Bitcoin runs on one blockchain, Ethereum runs on another, Solana on another. Each has different speeds and costs.
For sports betting, blockchain matters in three practical ways.
Deposits and withdrawals. When you deposit Bitcoin or USDT into a sportsbook like BlockBet, that transaction is recorded on the blockchain. You can verify it arrived by checking the transaction hash on a block explorer (like Etherscan for Ethereum or Solscan for Solana). Withdrawals work the same way. No bank involved, no 3-5 business day wait. Crypto withdrawals typically settle in minutes depending on network congestion.
Provably fair games. Some casino games use blockchain to prove the outcome wasn't rigged. The game generates a cryptographic hash before each round. After the round, you can verify that the result matches the hash, proving the outcome was determined before you placed your bet. This is called "provably fair" and it's only possible because of blockchain's transparency.
Smart contracts. These are programs that run on a blockchain and execute automatically when conditions are met. In betting, a smart contract could hold your wager in escrow and pay out the winner automatically based on the verified result, with no human middleman deciding whether to release your funds.
Not every crypto sportsbook uses all three of these features. Most use blockchain for payments (deposits and withdrawals) at a minimum. Provably fair verification and smart contract settlement are more common in crypto-native platforms.
BlockBet accepts 15+ cryptocurrencies including Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Tether (USDT), Tron (TRX), Ripple (XRP), Dogecoin (DOGE), and Litecoin (LTC).
