Navigating the Public Block Chain Ledger

Unlike bitcoin which has a "single" duplicated block chain, the Block Chain Ledger(PBCL), has a fully distributed block chain.

As a fully decentralised Public Block Chain Ledger, there needs to be a  mechanism to support the navigation through the P2P block chain segments, which make up the Global Block Chain Ledger.
Optionally this same mechanism supports the discovery of all block chain nodes, in a similar manner to bitcoin.

Node Discovery.
The PBCL makes use of industry standard DNS.
The PBCL root is the domain blockchainledger.net

This root contains the P2P seed seed.blockchainledger.net which will operate much like bitcoin seeds. The PBCL protocol does not support hard coded seeds, only the hard coding of the seed domain.

Each node within the PBCL is identified by a Secure Identification Number (SIN), this SIN is used as the "host" within the DNS "A" record entry.
This allows navigation to any segment in the same manner as any host on the Internet, the preferred means of linking segments of the PBCL together and navigation along the PBCL.

Secure Identification Number, Attributes
In order to support a number of regulatory and business requirements for identification or other related entity attributes, the PBCL supports optional SIN attributes.

Attribute:

• Sequence of key-value pairs (public proof) and hashes (private proof) to your SIN record. 
• Start out as anonymous identity, and as required, support opt out of anonymity on a per SIN basis, by attaching identifying key-value pairs (real.name = "John Smith").
• All key-value pair updates digitally signed by SIN owner (private key holder)
• Third parties may offer digital attestations:
• Identity Verification, Inc. digitally signs a SIN as passing their 100 points check.
• Auction Provider, digitally signs a SIN as having a certain reputation score, on their website.
• Decentralized market users, digitally sign one another's SINs, building a decentralized reputation, social media.

Example
Host SIN: 01ccf7bcaffbf94ce060c5ee79c2294ee992de521dac8da52e
A Record: 01ccf7bcaffbf94ce060c5ee79c2294ee992de521dac8da52e.blockchainledger.net
Attribute TXT Record:

v=sinatt;type=02;abn=19088024560;sig=0x3045022100970 CE1AD84D5E9012DE04502A67E7EDA5F9979 66C3C1497CF619199116FD27A802201E1DB 771D023A9DD827AAF1E6372FB0BA2A093D7 E3A7F1BA72BD19ACC40AC62C

Type: 01 = Attribute/Hash , 02= Attribute/Value pairs
