Blockchain Notary

Timestamps a cryptographic digest of a given document into the blockchain and connects it to a pubkeyhash to prove a chain of ownership. The document is considered to be owned by the initial creator and can be transferred to others. This is similar to how assets are issued and the issuer remains in control unless he transfers issuer status to a new ownership.

When reading back the blockchain the system should parse out notary data into the local database so when presented with a document, the API it can quickly hash it and determine if it already exists.

• Block no recorded in
• Hash of the document
• Txid

This is a list of unspendable addresses with which to burn coins to. When you send a coin to any of these addresses, they are permanently gone and can never be redeemed. 

You can prove this by sending a small test amount to the address and then checking a block explorer or using `getrawtransaction txid 1`. You should see the coins output to somehting like `"raw_scriptPubKey": "76a914000000000000000000000000000000000000000088ac"` Some block explorers are also smart enough to indicate in their user interface that the coins were destroyed. 

You can find the version number matching to the desired altcoin by checking two places in the code:

Litecoin might make your pockets heavy in 2015

Throughout this year I've been saying LTC under 0.01 would be a steal. In fact anything in the $2 range seems a good deal. My reasoning has been twofold, and frankly, obvious.

Early in 2014 when Charlie Lee (creator of litecoin) joined Coinbase, he gave a presentation about bitcoin. He was asked if Coinbase would add litecoin to which he responded, “not at the moment”. His reasoning was that the mass markets still didn't understand bitcoin, so it would potentially confuse people to add another crypto currency.

2014 has been the year of big bitcoin adoption, with names like Paypal (half in), Microsoft and Time, and the bitlicense. I believe by 2015, bitcoin will be a lot more mainstream and that Coinbase will have to adapt the the business model of GoCoin. The most likely candidate would be litecoin given the connection with Charlie Lee.

Whether this makes litecoin more valuable in the long term, it will bring litecoin in front of millions of existing Coinbas
