Transaction acquiescence is already afresh affecting the absolute Bitcoin network. Generally, this causes a lot of abashing added than annihilation else, and after-effects in acutely alike affairs until the next block is mined. This can be apparent as the following:
Your aboriginal transaction never confirming.
Another transaction, with the aforementioned bulk of bill traveling to and from the aforementioned addresses, appearing. This has a altered transaction ID.
Often, this altered transaction ID will confirm, and in assertive block explorers, you will see warnings about the aboriginal transaction accepting a bifold absorb or contrarily accepting invalid.
Ultimately though, just one transaction, with the absolute bulk of Bitcoins accepting sent, should confirm. If no affairs confirm, or added than one confirm, again this apparently isn't anon affiliated to transaction malleability.
However, it was noticed that there were some affairs beatific that accept not been mutated, and aswell are declining to confirm. This is because they await on a antecedent ascribe that aswell will not confirm.

Essentially, Bitcoin affairs absorb spending inputs (which can be anticipation of as Bitcoins "inside" a Bitcoin address) and again accepting some change back. For instance, if I had a individual ascribe of 10 BTC and capital to forward 1 BTC to someone, I would actualize a transaction as follows:
10 BTC -> 1 BTC (to the user) and 9 BTC (back to myself)
This way, there is a array of alternation that can be created for all Bitcoins from the antecedent mining transaction.
When Bitcoin amount does a transaction like this, it trusts that it will get the 9 BTC change back, and it will because it generated this transaction itself, or at the absolute least, the accomplished transaction will not affirm but annihilation is lost. It can anon forward on this 9 BTC in a added transaction after cat-and-mouse on this accepting accustomed because it knows area the bill are traveling to and it knows the transaction advice in the network.
However, this acceptance is wrong.
If the transaction is mutated, Bitcoin amount may end up aggravating to actualize a new transaction application the 9 BTC change, but based on amiss ascribe information. This is because the absolute transaction ID and accompanying abstracts has afflicted in the blockchain.
Hence, Bitcoin amount should never assurance itself in this instance, and should consistently delay on a acceptance for change afore sending on this change.

Bitcoin exchanges can configure their primary Bitcoin bulge to no best acquiesce change, with aught confirmations, to be included in any Bitcoin transaction. This may be configured by active bitcoind with the -spendzeroconfchange=0 option.
This is not abundant though, and this can aftereffect in a bearings area affairs cannot be beatific because there are not abundant inputs accessible with at atomic one acceptance to forward a new transaction. Thus, we aswell run a action which does the following:
Checks available, unspent but accustomed inputs by calling bitcoin-cli listunspent 1.
If there are beneath than x inputs (currently twelve) again do the following:
Work out what ascribe is for about 10 BTC.
Work out how to breach this into as abounding 1 BTC affairs as possible, abrogation abundant amplitude for a fee on top.
Call bitcoin-cli sendmany to forward that ~10 BTC ascribe to about 10 achievement addresses, all endemic by the Bitcoin marketplace.
This way, we can catechumen one 10 BTC ascribe into about ten 1 BTC inputs, which can be acclimated for added transactions. We do this if we are "running low" on inputs and there twelve of beneath remaining.
These accomplish ensure that we will abandoned anytime forward affairs with absolutely accustomed inputs.
One affair charcoal admitting - afore we implemented this change, some affairs got beatific that await on mutated change and will never be confirmed.
At present, we are researching the best way to resend these transactions. We will apparently zap the affairs at an off-peak time, although we wish to itemise all the affairs we anticipate should be zapped beforehand, which will yield some time.
One simple abode to abatement the affairs of acquiescence accepting an affair is to accept your Bitcoin bulge to affix to as abounding added nodes as possible. That way, you will be "shouting" your new transaction out and accepting it accustomed absolute quickly, which will acceptable beggarly that any mutated transaction will get drowned out and abandoned first.

There are some nodes out there that accept anti-mutation cipher in already. These are able to ascertain mutated affairs and abandoned canyon on the accurate transaction. It is advantageous to affix to trusted nodes like this, and account because implementing this (which will appear with its own risks of course).
All of these acquiescence issues will not be a botheration already the BIP 62 accessory to Bitcoin is implemented, which will accomplish acquiescence impossible. This abominably is some way off and there is no advertence accomplishing at present, let abandoned a plan for clearing to a new block type.
Although abandoned abrupt anticipation has been given, it may be accessible for approaching versions of Bitcoin software to ascertain themselves if acquiescence has occurred on change inputs, and again do one of the following:
Mark this transaction as abandoned and abolish it from the wallet, as we apperceive it will never affirm (potentially risky, abnormally if there is a reorg). Possibly acquaint the bulge owner.
Attempt to "repackage" the transaction, i.e. use the aforementioned from and to abode parameters, but with the absolute ascribe data from the change transaction as accustomed in the block.
