How many confirmations takes place before transaction is successful

Yesterday I attempted to send two bitcoin transfers from Livecoin and almost 24 hours later it hasn't been successful. When I check the transactions they have 99 and 95 confirmations. What does that mean?

what does this mean? is it that my transfer has failed?Anson 2017-11-14T18:28:26.593

No, it means that you never transfered anything in the first place.Rutger Versteegden 2017-11-14T19:54:07.297

Try to broadcast the transaction againRutger Versteegden 2017-11-14T19:54:22.397

Thank you. I will try again. The money was withdrawn from my livecoin account thoughAnson 2017-11-14T19:58:20.830

Actually, you did receive 30$ on https://blockchain.info/address/1BABUhAB7976cP7qVcAEfUrtmitYZYkTw7 with TXID https://blockchain.info/tx/6f5d6cc00cabf6259852048eef2f8d827b7d43c08da361cec08d67e468c5e1de I'm not sure if you were only talking about outputs, or inputs. In this case it seems you did receive the money, if this is your external wallet. sorry for my misunderstanding

But its not showing up in the wallet. Is it simply that I just need to wait some time longer?Anson 2017-11-14T20:10:05.523

No, it should be in your wallet right now. What wallet are you using if i may ask?Rutger Versteegden 2017-11-14T20:31:58.110

1Can you explain precisely how you determined that it hasn't been successful? Be as detailed as you can.David Schwartz 2017-11-16T08:32:26.873

It means that there have been 99 blocks after your transaction that have been succesfully confirmed.

99 blocks have basically confirmed that your transaction is real, and now ( and still does) belongs in the ( bitcoin ) blockchain.

So, yes your transaction has been successful, if you haven't been credited your bitcoin, or received it, something else is wrong. Mind linking me your TXID?

The more confirmations a transaction has, the less likely it will be that it could be overthrown in a 51% attack, or for example a double spend ( 1+ confirmations already makes sure that isn't the case)..

Generally a transaction with over 6 confirmations is seen as "Irreversible", (aslong as there isn't 1 miner with 51% hashpower) since it would be mathematically impossible to throw over these 6 blocks.

See Why is 6 the number of confirms that is considered secure? for more information about why these confirmations are so important.

That said, IIRC, new coins (from mining) may require longer proofs - 100 comes to my mind for bitcoin cash on some exchanges at the moment.TomTom 2017-11-14T16:15:34.780

Yes this is COINBASE_MATURITY and in Bitcoin is 100 blocks: https://github.com/bitcoin/bitcoin/blob/master/src/consensus/consensus.h
