Bitcoin Reference Line is a Bitcoin Fork which happened on block 523118 of the Bitcoin blockchain. Also, Bitcoin Reference Line is a fork from „Reference line coin“ on the block 57017. Every owner of Bitcoin and Reference line coin can claim their Bitcoin Reference Line with their private keys.

Bitcoin Reference Line supports an encrypted reference line. This means you can send a free text to the receiver of the transaction along with the transactions like „Payment for invoice #123“. The reference line is encrypted. Only the sender and the receiver of the transaction can see it.

The coin has a block time of 2 minutes instead of 10 minutes. It has a maximum block size of 36 MB.
It contains the complete UTXO set of Bitcoin and the size of the blockchain is only 4 GB instead of 200 GB.

So anybody who owns Bitcoin and has the private keys can also claim their Bitcoin Reference Line.

Supply and premine:

The maximum supply of the coin is 143 million coins. 38 million coins have been pre-mined. 17
million from the pre-mined coins have been distributed to the Bitcoin holders. 6 million coins have
been distributed to the Reference Line Coin holders. 5 million coins are for one initial investor. 4
million coins are for sale during the ICO. 6 million coins are currently being held by the development
team.

The reference line
As Bitcoin Reference Line shares most of its features with Bitcoin, but the “reference line” is not
available for Bitcoin. That is also the reason why Bitcoin Reference Line addresses are longer than
Bitcoin addresses. The addresses not only contain the public key hash for sending the coins but also
include a public key for the reference line encryption (AES encrypted). This assures that only the
sender and receiver are able to decrypt the reference line.
In fact, the sender of a payment can send any text message to the receiver of the payment along
with the transaction. And only the sender and the receiver are able to decrypt this message.
This reference line can have up to 1000 characters after it is encrypted and Base58 encoded. This
means you can use approximately 650 characters for the reference line (also including Chinese
characters).
The encryption key for the AES encryption is derived from a private and a public key pair through
elliptic curve multiplication.

ICO
The ICO is now live and will end on June 30th.
The price for one Bitcoin Reference Line will start at 0.00001000 BTC and will be increased after each purchase. After one million sold Bitcoin Reference Line the price will be 0.00002000 BTC. The price will reach 0.00005000 BTC for the last Bitcoin Reference line.

Up to 4 million coins are for sale.

Exchange listing
The coin will be listed on exrates.me in July. This exchange has a daily trading volume of 40 million USD. We already received the 3 BTC needed to the listing the coin there from an investor.
