| SOFT FORK | the first or first few blocks of a blockchain. |
| BLOCK | block explorer is an online tool to view all transactions, past and current, on the blockchain. they provide useful information such as network hash rate and transaction growth. |
| BLOCK EXPLORER | a soft fork differs from a hard fork in that only previously valid transactions are made invalid. since old nodes recognize the new blocks as valid, a soft fork is essentially backward-compatible. this type of fork requires most miners upgrading in order to enforce, while a hard fork requires all nodes to agree on the new version. |
| MASF | a ledger maintained by a central agency. |
| OTC EXCHANGE | is the practice and study of techniques for secure communication in the presence of third parties called adversaries. cryptocurrencies are built on cryptography. they are not secured by people or by trust, but by math. it is more probable that an asteroid falls on your house than that a bitcoin address is compromised. |
| BLOCK TIMESTAMP | blocks are packages of data that carry permanently recorded data on the blockchain network. |
| DOUBLE SPENDING | each block contains a timestamp in unix. they help to make it more difficult for someone else to manipulate the blockchain. |
| GENESIS BLOCK | an exchange in which traders make deals with each other directly, rather than relying on a central exchange to mediate between them |
| CENTRAL LEDGER | miner activated soft fork - it’s a mechanism by which miners trigger activation of soft forks when a majority signals the readiness to upgrade. this allows for a faster activation time for the soft fork, leaving full nodes to upgrade at their leisure. |
| CRYPTOGRAPHY | a common flaw in some cryptocurrency blockchains where the system of rules is not in motion properly, allowing malicious users to try and spend their unique codes in multiple places. this causes coins spent that are already spent somewhere else, making one of the receivers end up with nothing. |
