La carta prepagata ora è disponibile a tutti.
E' richiesto però che sia presente almeno 1 g d'oro sul vostro account.

Non è ancora possibile però ritirare sotto forma di Bitcoin ...

284  Bitcoin / Bitcoin Discussion / Bitcoin Core version 0.11.2 released on: November 13, 2015, 12:26:08 PM
Bitcoin Core version 0.11.2 is now available from:

https://bitcoin.org/bin/bitcoin-core-0.11.2

This is a new minor version release, bringing bug fixes, the BIP65
(CLTV) consensus change, and relay policy preparation for BIP113. It is
recommended to upgrade to this version as soon as possible.

Please report bugs using the issue tracker at github:

https://github.com/bitcoin/bitcoin/issues

Upgrading and downgrading
=========================

How to Upgrade
--------------

If you are running an older version, shut it down. Wait until it has completely
shut down (which might take a few minutes for older versions), then run the
installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or
bitcoind/bitcoin-qt (on Linux).

Downgrade warning
------------------

Because release 0.10.0 and later makes use of headers-first synchronization and
parallel block download (see further), the block files and databases are not
backwards-compatible with pre-0.10 versions of Bitcoin Core or other software:

* Blocks will be stored on disk out of order (in the order they are
received, really), which makes it incompatible with some tools or
other programs. Reindexing using earlier versions will also not work
anymore as a result of this.

* The block index database will now hold headers for which no block is
stored on disk, which earlier versions won't support.

If you want to be able to downgrade smoothly, make a backup of your entire data
directory. Without this your node will need start syncing (or importing from
bootstrap.dat) anew afterwards. It is possible that the data from a completely
synchronised 0.10 node may be usable in older versions as-is, but this is not
supported and may break as soon as the older version attempts to reindex.

This does not affect wallet forward or backward compatibility. There are no
known problems when downgrading from 0.11.x to 0.10.x.

Notable changes since 0.11.1
============================

BIP65 soft fork to enforce OP_CHECKLOCKTIMEVERIFY opcode
--------------------------------------------------------

This release includes several changes related to the [BIP65][] soft fork
which redefines the existing OP_NOP2 opcode as OP_CHECKLOCKTIMEVERIFY
(CLTV) so that a transaction output can be made unspendable until a
specified point in the future.

1. This release will only relay and mine transactions spending a CLTV
   output if they comply with the BIP65 rules as provided in code.

2. This release will produce version 4 blocks by default. Please see the
   *notice to miners* below.

3. Once 951 out of a sequence of 1,001 blocks on the local node's best block
   chain contain version 4 (or higher) blocks, this release will no
   longer accept new version 3 blocks and it will only accept version 4
   blocks if they comply with the BIP65 rules for CLTV.

For more information about the soft-forking change, please see
https://github.com/bitcoin/bitcoin/pull/6351

Graphs showing the progress towards block version 4 adoption may be
found at the URLs below:

- Block versions over the last 50,000 blocks as progress towards BIP65
  consensus enforcement: http://bitcoin.sipa.be/ver-50k.png

- Block versions over the last 2,000 blocks showing the days to the
  earliest possible BIP65 consensus-enforced block: http://bitcoin.sipa.be/ver-2k.png

**Notice to miners:** Bitcoin Core’s block templates are now for
version 4 blocks only, and any mining software relying on its
getblocktemplate must be updated in parallel to use libblkmaker either
version 0.4.3 or any version from 0.5.2 onward.

- If you are solo mining, this will affect you the moment you upgrade
  Bitcoin Core, which must be done prior to BIP65 achieving its 951/1001
  status.

- If you are mining with the stratum mining protocol: this does not
  affect you.

- If you are mining with the getblocktemplate protocol to a pool: this
  will affect you at the pool operator’s discretion, which must be no
  later than BIP65 achieving its 951/1001 status.

BIP113 mempool-only locktime enforcement using GetMedianTimePast()
----------------------------------------------------------------

Bitcoin transactions currently may specify a locktime indicating when
they may be added to a valid block.  Current consensus rules require
that blocks have a block header time greater than the locktime specified
in any transaction in that block.

Miners get to choose what time they use for their header time, with the
consensus rule being that no node will accept a block whose time is more
than two hours in the future.  This creates a incentive for miners to
set their header times to future values in order to include locktimed
transactions which weren't supposed to be included for up to two more
hours.

The consensus rules also specify that valid blocks may have a header
time greater than that of the median of the 11 previous blocks.  This
GetMedianTimePast() time has a key feature we generally associate with
time: it can't go backwards.

[BIP113][] specifies a soft fork (**not enforced in this release**) that
weakens this perverse incentive for individual miners to use a future
time by requiring that valid blocks have a computed GetMedianTimePast()
greater than the locktime specified in any transaction in that block.

Mempool inclusion rules currently require transactions to be valid for
immediate inclusion in a block in order to be accepted into the mempool.
This release begins applying the BIP113 rule to received transactions,
so transaction whose time is greater than the GetMedianTimePast() will
no longer be accepted into the mempool.

**Implication for miners:** you will begin rejecting transactions that
would not be valid under BIP113, which will prevent you from producing
invalid blocks if/when BIP113 is enforced on the network. Any
transactions which are valid under the current rules but not yet valid
under the BIP113 rules will either be mined by other miners or delayed
until they are valid under BIP113. Note, however, that time-based
locktime transactions are more or less unseen on the network currently.

**Implication for users:** GetMedianTimePast() always trails behind the
current time, so a transaction locktime set to the present time will be
rejected by nodes running this release until the median time moves
forward. To compensate, subtract one hour (3,600 seconds) from your
locktimes to allow those transactions to be included in mempools at
approximately the expected time.

Windows bug fix for corrupted UTXO database on unclean shutdowns
----------------------------------------------------------------

Several Windows users reported that they often need to reindex the
entire blockchain after an unclean shutdown of Bitcoin Core on Windows
(or an unclean shutdown of Windows itself). Although unclean shutdowns
remain unsafe, this release no longer relies on memory-mapped files for
the UTXO database, which significantly reduced the frequency of unclean
shutdowns leading to required reindexes during testing.

For more information, see: https://github.com/bitcoin/bitcoin/pull/6917

Other fixes for database corruption on Windows are expected in the
next major release.

Credo che si, sia compatibile, ma poi avrai un nuovo seed.
Quello che avviene, da quel che ho capito, è semplicemente un trasferimento dei Bitcoin dagli indirizzi del vecchio seed su quello nuovo.

Mal che vada, basta fare un trasferimento normale.
289  Local / Italiano (Italian) / Re: E' uscito Electrum v2.5.4! on: November 12, 2015, 02:36:50 PM
Il cold wallet credo che sia compatibile con le nuove versioni, nel senso che lui prende i Bitcoin e li sposta sui nuovi indirizzi.

Tu non stai cercando di preservare i tuoi Bitcoin, stai cercando di preservare i tuoi indirizzi.
In genere questa non è una cosa prevista da nessun software Bitcoin, si cerca invece di sconsigliare come pratica.

Quella stringa è il tuo backup, devi avere anche la password.

Con quella stringa dovresti riuscire a riattivare il wallet anche su iPhone.

Sembra che sia possibile prendere il backup dall'app precedente.

Se però non hai un backup, e l'app sull'Ipad non è accessibile, credo che non ci sia modo.
