=== Transactions, Blocks, Mining, and the Blockchain
((("bitcoin","implementation of", id="ix_ch02-asciidoc0", range="startofrange")))The bitcoin system, unlike traditional banking and payment systems, is based on de-centralized trust. Instead of a central trusted authority, in bitcoin, trust is achieved as an emergent property from the interactions of different participants in the bitcoin system. In this chapter, we will examine bitcoin from a high level by tracking a single transaction through the bitcoin system and watch as it becomes "trusted" and accepted by the bitcoin mechanism of distributed consensus and is finally recorded on the blockchain, the distributed ledger of all transactions. Subsequent chapters will delve into the technology behind transactions, the network, and mining.

In this chapter, we saw how transactions build a chain that moves value from owner to owner. We also tracked Alice's transaction, from the moment it was created in her wallet, through the bitcoin network and to the miners who recorded it on the blockchain. In the next few chapters we will examine the specific technologies behind wallets, addresses, signatures, transactions, the network and finally mining.

=== Introduction
((("bitcoin","establishing ownership of")))Ownership of bitcoin is established through _digital keys_, _bitcoin addresses_, and _digital signatures_. The digital keys are not actually stored in the network, but are instead created and stored by users in a file, or simple database, called a _wallet_. The digital keys in a user's wallet are completely independent of the bitcoin protocol and can be generated and managed by the user's wallet software without reference to the blockchain or access to the Internet. Keys enable many of the interesting properties of bitcoin, including de-centralized trust and control, ownership attestation, and the cryptographic-proof security model.

Every bitcoin transaction requires a valid digital signature to be included in the blockchain, which can only be generated with a secret key; therefore, anyone with a copy of that key has control of the bitcoin in that account. The digital signature used to spend funds is also referred to as a _witness_, a term used in cryptography. The witness data in a bitcoin transaction testifies to the true ownership of the funds being spent.

==== Mastercoin
((("meta-coin platforms","mastercoin protocol")))Mastercoin is a protocol layer on top of bitcoin that supports a platform for various applications extending the bitcoin system. Mastercoin uses the currency MST as a token for conducting Mastercoin transactions but it is not primarily a currency. Rather, it is a platform for building other things, such as user currencies, smart property tokens, de-centralized asset exchanges, and contracts. Think of Mastercoin as an application-layer protocol on top of bitcoin's financial transaction transport layer, just like HTTP runs on top of TCP.

Think of Mastercoin as an application-layer protocol on top of bitcoin's financial transaction transport layer, just like HTTP runs on top of TCP.
Mastercoin operates primarily through transactions sent to and from a special bitcoin address called the((("exodus addresses"))) "exodus" address (+1EXoDusjGwvnjZUyKkxZ4UHEf77z6A5S4P+), just like HTTP uses a specific TCP port (port 80) to differentiate its traffic from the rest of the TCP traffic. The Mastercoin protocol is gradually transitioning from using the specialized exodus address and multi-signatures to using the OP_RETURN bitcoin operator to encode transaction metadata.
