+
+
+Transactions block is an added record to the block which allow to attached values transfer to the block.
+
+A transaction descript a transfer of value between account protected via [ECC][1]
+(we use [secp256k1][5] see code [ECKeys.pm][2]).
+
+You can register your [keypair][4] in the [admin](/admin/) section under [signup / keygen][3].
+
+A transaction has inputs, outputs, and signatures,
+in order be valid 
+
+- the total of inputs must be greater than the total of ouputs
+- every account on the input side must have enough balance to satisfy the transactions
+- all signature attached to the transaction must be authentic and the signed message not tempered
+
+example of transaction in ([yaml][6] format)
