RSK Blockchain
Smart Contracts
for Bitcoin

RSK’s goal is to add value and functionality to
the bitcoin ecosystem by enabling smart-contracts,
near instant payments, and higher-scalability.

How RSK is connected
to bitcoin?

Merged mining
with Bitcoin

The first point of contact is through mining.
The bitcoin miners do what is known as
merged mining, securing both networks with the same
infrastructure and energy consumption.

2-way peg with Bitcoin
The second point of contact is the
2-way peg, also known as the bridge

This component connects both networks to allow the transfer of bitcoins to RSK, thereby allowing
developers to interact with smart contracts. They pay gas using the same bitcoin, the smart bitcoin.

To do so

You send bitcoin to a special address,
where they are locked in the bitcoin network.
Next, in the same address over in the RSK network,
that same bitcoin is released to the user for use
in the RSK network. This is called peg-in.

You can do the reverse operation called peg-out,
by sending your bitcoin to a special address in
the RSK network, and receiving your bitcoin back
in the bitcoin network.

R-BTC Token

The Smart Bitcoin (R-BTC) is the token used to pay for the execution of transactions in RSK. You can
convert BTC into R-BTC by sending BTC through the 2-way peg (both in Testnet and Mainnet), or by using
the faucet in Testnet, or exchanges in Mainnet.

Gas is the internal pricing for running a transaction or contract. When you send tokens, interact with a contract, send R-BTC, or do anything else on the blockchain, you must pay for that computation. That payment is calculated as gas. In RSK this is paid in R-BTC.
