Most digital currencies solve the problem by relinquishing some control to a central authority, which keeps track of each account’s balance. This was an unacceptable solution for Szabo. "I was trying to mimic as closely as possible in cyberspace the security and trust characteristics of gold, and chief among those is that it doesn’t depend on a trusted central authority," he said. In 2008, a mysterious figure who wrote under the name Satoshi Nakamoto released a proposal for bitcoin. Nakamoto’s true identity remained a secret, which led to speculation about a long list of people suspected to be Nakamoto. Although Szabo has repeatedly denied it, people have speculated that he is Nakamoto.

unspent outputs of transactionsunspent transaction outputs
In cryptocurrencies, an unspent transaction output (UTXO) is an output of a blockchain transaction that has not been spent, i.e. used as an input in a new transaction. Bitcoin is the most famous example of a cryptocurrency that uses the UTXO model. Outputs are a superset of UTXOs. Accordingly, UTXOs are a subset of the outputs superset. Bitcoin UTXO lifespans have been studied. In the case of a valid blockchain transaction, unspent outputs (and only unspent outputs) may be used to effect further transactions. The requirement that only unspent outputs may be used in further transactions is necessary to prevent double spending and fraud.

Hash trees are also used in the IPFS, Btrfs and ZFS file systems (to counter data degradation ); Dat protocol; Apache Wave protocol ; Git and Mercurial distributed revision control systems; the Tahoe-LAFS backup system; Zeronet; the Bitcoin and Ethereum peer-to-peer networks ; the Certificate Transparency framework; and a number of NoSQL systems such as Apache Cassandra, Riak, and Dynamo. Suggestions have been made to use hash trees in trusted computing systems. The initial Bitcoin implementation of Merkle trees by Satoshi Nakamoto applies the compression step of the hash function to an excessive degree, which is mitigated by using Fast Merkle Trees.

., UBS was experimenting with "smart bonds" that use the bitcoin blockchain in which payment streams could hypothetically be fully automated, creating a self-paying instrument. A smart contract is "a computerized transaction protocol that executes the terms of a contract". A blockchain-based smart contract is visible to all users of said blockchain. However, this leads to a situation where bugs, including security holes, are visible to all yet may not be quickly fixed. Such an attack, difficult to fix quickly, was successfully executed on The DAO in June 2016, draining in Ether while developers attempted to come to a solution that would gain consensus.
