A blockchain is a public ledger, recording every transaction involving the currencies and virtual tokens running on it. This structure makes it impossible for a token holder to “double-sell” a token—accepting a transfer for the same token to two different sources. Blockchains are distributed ledgers, which means that no one person, group, or organization controls them. In addition, blockchains rely on advanced cryptography to provide security to users. Each user has his or her own private key that allows access to his or her blockchain assets. That key is a long string of random characters that is very difficult for a computer—let alone another user—to guess. After a transaction has been recorded and confirmed on the blockchain, it cannot be changed. This helps assure investors that no one can falsify transactions after the fact. These protections are also embedded in technologies like smart contracts and multi signature wallets, utilized on this platform to ensure every step in the real estate transactional process is verified through digital consensus, thus making every step more efficient, more transparent and more secure. There is no higher level of investment security.
