redfish	e1c7af35d4	cmake: transitive deps and remove deprecated LINK_* ... Keep the immediate direct deps at the library that depends on them, declare deps as PUBLIC so that targets that link against that library get the library's deps as transitive deps. Break dep cycle between blockchain_db <-> crytonote_core. No code refactoring, just hide cycle from cmake so that it doesn't complain (cycles are allowed only between static libs, not shared libs). This is in preparation for supproting BUILD_SHARED_LIBS cmake built-in option for building internal libs as shared.	8 years ago

moneromooo-monero	c3b3260ae5	New "Halfway RingCT" outputs for coinbase transactions ... When RingCT is enabled, outputs from coinbase transactions are created as a single output, and stored as RingCT output, with a fake mask. Their amount is not hidden on the blockchain itself, but they are then able to be used as fake inputs in a RingCT ring. Since the output amounts are hidden, their "dustiness" is not an obstacle anymore to mixing, and this makes the coinbase transactions a lot smaller, as well as helping the TXO set to grow more slowly. Also add a new "Null" type of rct signature, which decreases the size required when no signatures are to be stored, as in a coinbase tx.	8 years ago
moneromooo-monero	6f526cdff8	rct: log why verification fails ... and remove some unnecessary variables in the checking code	8 years ago
moneromooo-monero	d4b8991e44	rct: serialize txnFee as varint	8 years ago
moneromooo-monero	d4b62a1e29	rct amount key modified as per luigi1111's recommendations ... This allows the key to be not the same for two outputs sent to the same address (eg, if you pay yourself, and also get change back). Also remove the key amounts lists and return parameters since we don't actually generate random ones, so we don't need to save them as we can recalculate them when needed if we have the correct keys.	8 years ago
moneromooo-monero	93f5c625f0	rct: rework v2 txes into prunable and non prunable data ... Nothing is pruned, but this allows easier changes later.	8 years ago
moneromooo-monero	d93746b6d3	rct: rework the verification preparation process ... The whole rct data apart from the MLSAGs is now included in the signed message, to avoid malleability issues. Instead of passing the data that's not serialized as extra parameters to the verification API, the transaction is modified to fill all that information. This means the transaction can not be const anymore, but it cleaner in other ways.	8 years ago
moneromooo-monero	3ab2ab3e76	rct: change the simple flag to a type ... for future expansion	8 years ago
Shen Noether	c5be4b0bea	rct: avoid the need for the last II element ... This element is used in the generation of the MLSAG, but isn't needed in verification. Also misc changes in the cryptonote code to match, by mooo.	8 years ago
moneromooo-monero	b337aea6cc	rct: do not serialize senderPk - it is not used anymore	8 years ago
moneromooo-monero	9b70856ccb	rct: make the amount key derivable by a third party with the tx key ... Scheme design from luigi1114.	8 years ago

Shen Noether	4fd01f2bee	ringct: "simple" ringct variant ... Allows the fake outs to be in different positions for each ring. For rct inputs only.	8 years ago
moneromooo-monero	35dce5c70c	ringct: fix size unit mismatch calling keccak	8 years ago
moneromooo-monero	20e50ec7f7	ringct: do not serialize what can be reconstructed ... The mixRing (output keys and commitments) and II fields (key images) can be reconstructed from vin data. This saves some modest amount of space in the tx.	8 years ago
moneromooo-monero	73d59f17e1	ringct: catch errors from ge_frombytes_vartime	8 years ago
moneromooo-monero	359f46901e	ringct: add missing size check for ecdhInfo	8 years ago
moneromooo-monero	229968eafc	ringct: change asserts to return false for boolean functions	8 years ago
moneromooo-monero	dc4aad7eb5	add rct to the protocol ... It is not yet constrained to a fork, so don't use on the real network or you'll be orphaned or rejected.	8 years ago
moneromooo-monero	dee42d6dac	ringct: add functions to commit to an amount ... One to commit to an amount with zero key (for use with fake commitments for pre-rct outputs), and one with an arbitrary key (for rct outputs).	8 years ago
moneromooo-monero	cc7f449d57	make rct tx serialization work ... It may be suboptimal, but it's a pain to have to rebuild everything when some of this changes. Also, no clue why there seems to be two different code paths for serializing a tx...	8 years ago
moneromooo-monero	54f7429cf6	ringct: allow no outputs, and add tests for this and fees	8 years ago
moneromooo-monero	e99904ac31	ringct: make fee optional	8 years ago
Shen Noether	f8c04ad94f	ringct: txn fee stuff	8 years ago
moneromooo-monero	66f96260b2	ringct: new {gen,decode}Rct APIs for convenience ... A new version of genRct takes the mixRing as parameter, instead of the inPk. inPk are part of the mixRing, and it is cleaner to pass the mixRing data than to fetch it from the RingCT code. A new version of decodeRct also returns the mask. Also, failure to decode throws, so errors are properly detected.	8 years ago
