  : **Note**: The following is an excerpt from the official [[dido:public:ra:xapend:xapend.a_glossary:b:bitcoin|Bitcoin]] site. It is provided here as a convenience and is not authoritative. Refer to the original document(s) as the authoritative reference.

=== Abstract === 
  : //This BIP describes a new type of Bitcoin address to support arbitrarily complex transactions. Complexity in this context is defined as what information is needed by the recipient to respend the received [[dido:public:ra:xapend:xapend.a_glossary:c:coins|coins]], in contrast to needing a single ECDSA [[dido:public:ra:xapend:xapend.a_glossary:p:private_key|private key]] as in current implementations of Bitcoin.//

  : //In essence, an address encoded under this proposal represents the encoded hash of a script, rather than the encoded hash of an ECDSA [[dido:public:ra:xapend:xapend.a_glossary:p:public_key|public key]].//

=== Motivation === 
  : //Enable "end-to-end" secure wallets and payments to fund escrow transactions or other complex transactions. Enable third-party [[dido:public:ra:xapend:xapend.a_glossary:b:bitcoin_wallet|wallet]] security services.//
