An account can be made signable with only its regular key by disabling the master key. Now an account can also be made exclusively multisigned by both disabling the master key and having no regular key. In order to prevent an account from becoming unsignable the network uses these rules: o An account can always add or replace a regular key or a SignerList as long as the fee and reserve can be met by the account. o The master key on an account can be disabled if either a regular key or a SignerList (or both) is present on the account. Either the regular key or the SignerList can be used to re-enable the master key later if that is desired. o The regular key on an account may only be removed if either the master key is enabled or the account has a SignerList (or both). o The SignerList on an account may only be removed if either the master key is enabled or a regular key is present (or both). As a consequence of this change, the tecMASTER_DISABLED error code is renamed to tecNO_ALTERNATIVE_KEY. The error code number (130 decimal) is unchanged.
#The World’s Fastest and Most Secure Payment System
What is Ripple?
Ripple is the open-source, distributed payment protocol that enables instant payments with low fees, no chargebacks, and currency flexibility (for example dollars, yen, euros, bitcoins, or even loyalty points). Businesses of any size can easily build payment solutions such as banking or remittance apps, and accelerate the movement of money. Ripple enables the world to move value the way it moves information on the Internet.
What is a Gateway?
Ripple works with gateways: independent businesses which hold customer deposits in various currencies such as U.S. dollars (USD) or Euros (EUR), in exchange for providing cryptographically-signed issuances that users can send and trade with one another in seconds on the Ripple network. Within the protocol, exchanges between multiple currencies can occur atomically without any central authority to monitor them. Later, customers can withdraw their Ripple balances from the gateways that created those issuances.
How do Ripple payments work?
A sender specifies the amount and currency the recipient should receive and Ripple automatically converts the sender’s available currencies using the distributed order books integrated into the Ripple protocol. Independent third parties acting as market makers provide liquidity in these order books.
Ripple uses a pathfinding algorithm that considers currency pairs when converting from the source to the destination currency. This algorithm searches for a series of currency swaps that gives the user the lowest cost. Since anyone can participate as a market maker, market forces drive fees to the lowest practical level.
What can you do with Ripple?
The protocol is entirely open-source and the network’s shared ledger is public information, so no central authority prevents anyone from participating. Anyone can become a market maker, create a wallet or a gateway, or monitor network behavior. Competition drives down spreads and fees, making the network useful to everyone.
###Key Protocol Features
-
XRP is Ripple’s native [cryptocurrency] (http://en.wikipedia.org/wiki/Cryptocurrency) with a fixed supply that decreases slowly over time, with no mining. XRP acts as a bridge currency, and pays for transaction fees that protect the network against spam.
-
Pathfinding discovers cheap and efficient payment paths through multiple order books allowing anyone to trade anything. When two accounts aren’t linked by relationships of trust, the Ripple pathfinding engine considers intermediate links and order books to produce a set of possible paths the transaction can take. When the payment is processed, the liquidity along these paths is iteratively consumed in best-first order.
-
Consensus confirms transactions in an atomic fashion, without mining, ensuring efficient use of resources.
