That means somebody who wants a loan can sell some bonds and whoever owns that bond receives the re-payments and any interest that accrues. The bond, being an asset like any other, is transferable - if you get tired of receiving the repayments you can sell the bond to somebody else. Once the full amount of the bond has been repaid, we say it has reached maturity.
Some bonds never mature and yield interest payments in perpetuity. A stock is somewhat similar to a bond, except it never matures, yields irregular dividend payments instead of regular interest payments and confers voting rights upon the owner.
In this document we will talk mostly about bonds, but the same ideas can be applied to build a stock market too. A ratings agency evaluates the creditworthiness of bond sellers and assigns bonds a consistent score AAA, AA, junk, etc. Bitcoin script allows some flexibility, eg, by allowing threshold signatures or password based coins.
But we lack the ability to pay to anyone who satisfies an arbitrary policy. Ciphertext-policy attribute based encryption CP-ABE allows you to encrypt some data such that anyone in possession of a key with attributes that match a formula can decrypt it. A common problem encountered when designing advanced financial markets on top of Bitcoin is the need for a place to temporarily store small pieces of data, keyed by hash.
This is because the block chain is not always the right place to put non-trivial amounts of data. The Kademlia protocol and similar designs have solved this problem, albeit in a way that is vulnerable to a variety of DoS and Sybil attacks.
But there is no network designed specifically for use in Bitcoin related systems. Today, their most common usage is in file sharing networks that are typically used for copyright infringement.
A separate Kademlia network can be built that is optimized solely for financial usage. Nodes would restrict the size of the stored data and artificially throttle the serving of it, thus discouraging storage of movies, games, MP3s and other such things. Initial insertion or value longevity could be made subject to proof of a Bitcoin stake aged balances or posted bond , deterring garbage.
This means users who are interested in the financial applications but don't wish to assist file sharing can donate their resources to the network without issue. We start with the familiar structure of an independent P2P broadcast network that connects to the financial hashmap. There is no need for an alternative block chain. Bonds can be modeled as if they were Smart Property. The issuer, timestamp and value fields should be self explanatory.
The bond message would be inserted into the hashmap so others who know its hash can find it. The start point identifies an output on the Bitcoin network that is created by the bond issuer. That output has a special form: it is of zero value and contains a script like this:.
This output tracks the current owner of the bond. The owner receives the repayments and any accrued interest. Retrieved 10 June January 5, October 5, The Globe and Mail. The Woodbridge Company.
