The block chain is an on the web decentralised public ledger of digital transactions which have taken place. It's digital currency's equivalent of a top street bank's ledger that records transactions between two parties.

Just as our modern banking system couldn't function with no way to record the exchanges of fiat currency between individuals, so too could an electronic digital network not function with no trust that originates from the capability to accurately record the exchange of digital currency between parties. block chain software

It's decentralised in the sense that, unlike a traditional bank which can be the only real holder of a digital master ledger of its account holder's savings the block chain ledger is shared among all members of the network and isn't subject to the terms and conditions of any particular financial institution or country.

A decentralised monetary network ensures that, by sitting not in the evermore connected current financial infrastructure you can mitigate the risks of being section of it when things go wrong. The 3 main risks of a centralised monetary system which were highlighted as a result of the 2008 financial crisis are credit, liquidity and operational failure. In the US alone since 2008 there were 504 bank failures due to insolvency, there being 157 in 2010 alone. Typically such a collapse doesn't jeopardize account holder's savings due to federal/national backing and insurance for the very first few hundred thousand dollars/pounds, the banks assets usually being absorbed by another financial institution but the impact of the collapse can cause uncertainty and short-term issues with accessing funds. Since a decentralised system like the Bitcoin network isn't dependent on a bank to facilitate the transfer of funds between 2 parties but instead depends on its tens of thousands of users to authorise transactions it is more resilient to such failures, it having as much backups as you can find members of the network to make certain transactions remain authorised in case of 1 person in the network'collapsing'(see below blockchain technology).

A bank need not fail however to affect savers, operational I.T. failures such as for instance those that recently stopped RBS and Lloyds'customers accessing their accounts for weeks can affect one's ability to withdraw savings, these being a consequence of a 30-40 year old legacy I.T. infrastructure that is groaning under the strain of maintaining the growth of customer spending and a lack of investment in general. A decentralised system isn't reliant on this kind of infrastructure, it instead being on the basis of the combined processing power of its tens of thousands of users which ensures the capability to scale up as necessary, a mistake in virtually any part of the system not causing the network to grind to a halt.

Liquidity is a final real threat of centralised systems, in 2001 Argentine banks froze accounts and introduced capital controls as a result of the debt crisis, Spanish banks in 2012 changed their small print to allow them to block withdrawals over a certain amount and Cypriot banks briefly froze customer accounts and used up to 10% of individual's savings to help pay off the National Debt blockchain database.

As Jacob Kirkegaard, an economist at the Peterson Institute for International Economics told the New York Times on the Cyrpiot example, "What the offer reflects is that becoming an unsecured as well as secured depositor in euro area banks is not as safe as it used to be." In a decentralised system payment happens without a bank facilitating and authorising the transaction, payments only being validated by the network where you can find sufficient funds, there being no third party to prevent a transaction, misappropriate it or devalue the amount one holds.
