We are pleased to release Litecoin Core 0.16.0 release candidate. This is a new major version release, including new features, various bugfixes and performance improvements, as well as updated translations.
It is recommended for power users to upgrade to this version. After sufficient testing, Litecoin Core v0.16.0 final will be released and is recommended for all users to upgrade.
Litecoin Core 0.16.0 introduces full support for segwit in the wallet and user interfaces. A new
-addresstype argument has been added, which supports
p2sh-segwit (default), and
bech32 addresses. It controls what kind of addresses are produced by
-changetype argument has also been added, with the same options, and by default equal to
-addresstype, to control which kind of change is used.
address_type parameter has been added to the
addmultisigaddress RPCs to specify which type of address to generate. A
change_type argument has been added to the
fundrawtransaction RPC to override the
-changetype argument for specific transactions.
- All segwit addresses created through
*multisigRPCs explicitly get their redeemscripts added to the wallet file. This means that downgrading after creating a segwit address will work, as long as the wallet file is up to date.
- All segwit keys in the wallet get an implicit redeemscript added, without it being written to the file. This means recovery of an old backup will work, as long as you use new software.
- All keypool keys that are seen used in transactions explicitly get their redeemscripts added to the wallet files. This means that downgrading after recovering from a backup that includes a segwit address will work
Note that some RPCs do not yet support segwit addresses. Notably,
verifymessage doesn’t support segwit addresses, nor does
importmulti at this time. Support for segwit in those RPCs will continue to be added in future versions.
P2WPKH change outputs are now used by default if any destination in the transaction is a P2WPKH or P2WSH output. This is done to ensure the change output is as indistinguishable from the other outputs as possible in either case.
BIP173 (Bech32) Address support (“ltc1…” addresses)
Full support for native segwit addresses (BIP173 / Bech32) has now been added. This includes the ability to send to BIP173 addresses (including non-v0 ones), and generating these addresses (including as default new addresses, see above).
A checkbox has been added to the GUI to select whether a Bech32 address or P2SH-wrapped address should be generated when using segwit addresses. When launched with
-addresstype=bech32 it is checked by default. When launched with
-addresstype=legacy it is unchecked and disabled.
HD-wallets by default
Due to a backward-incompatible change in the wallet database, wallets created with version 0.16.0 will be rejected by previous versions. Also, version 0.16.0 will only create hierarchical deterministic (HD) wallets. Note that this only applies to new wallets; wallets made with previous versions will not be upgraded to be HD.
Wallets directory configuration (
Litecoin Core now has more flexibility in where the wallets directory can be located. Previously wallet database files were stored at the top level of the litecoin data directory. The behavior is now:
- For new installations (where the data directory doesn’t already exist), wallets will now be stored in a new
wallets/subdirectory inside the data directory by default.
- For existing nodes (where the data directory already exists), wallets will be stored in the data directory root by default. If a
wallets/subdirectory already exists in the data directory root, then wallets will be stored in the
wallets/subdirectory by default.
- The location of the wallets directory can be overridden by specifying a
<path>can be an absolute path to a directory or directory symlink.
Care should be taken when choosing the wallets directory location, as if it becomes unavailable during operation, funds may be lost.
The minimum version of the GCC compiler required to compile Litecoin Core is now 4.8. No effort will be made to support older versions of GCC. See discussion in issue #11732 for more information. The minimum version for the Clang compiler is still 3.3. Other minimum dependency versions can be found in
doc/dependencies.md in the repository.
Pruned nodes can now signal BIP159’s NODE_NETWORK_LIMITED using service bits, in preparation for full BIP159 support in later versions. This would allow pruned nodes to serve the most recent blocks. However, the current change does not yet include support for connecting to these pruned peers.
The SHA256 hashing optimizations for architectures supporting SSE4, which lead to ~50% speedups in SHA256 on supported hardware (~5% faster synchronization and block validation), have now been enabled by default. In previous versions they were enabled using the
--enable-experimental-asm flag when building, but are now the default and no longer deemed experimental.
- The option to reuse a previous address has now been removed. This was justified by the need to “resend” an invoice, but now that we have the request history, that need should be gone.
- Support for searching by TXID has been added, rather than just address and label.
- A “Use available balance” option has been added to the send coins dialog, to add the remaining available wallet balance to a transaction output.
- A toggle for unblinding the password fields on the password dialog has been added.
A new RPC
rescanblockchain has been added to manually invoke a blockchain rescan. The RPC supports start and end-height arguments for the rescan, and can be used in a multiwallet environment to rescan the blockchain at runtime.
savemempool RPC has been added which allows the current mempool to be saved to disk at any time to avoid it being lost due to crashes / power loss.
Safe mode disabled by default
Safe mode is now disabled by default and must be manually enabled (with
-disablesafemode=0) if you wish to use it. Safe mode is a feature that disables a subset of RPC calls – mostly related to the wallet and sending – automatically in case certain problem conditions with the network are detected. However, developers have come to regard these checks as not reliable enough to act on automatically. Even with safe mode disabled, they will still cause warnings in the
warnings field of the
getneworkinfo RPC and launch the
Renamed script for creating JSON-RPC credentials
share/rpcuser/rpcuser.py script was renamed to
share/rpcauth/rpcauth.py. This script can be used to create
rpcauthcredentials for a JSON-RPC user.
validateaddress RPC output has been extended with a few new fields, and support for segwit addresses (both P2SH and Bech32). Specifically:
- A new field
iswitnessis True for P2WPKH and P2WSH addresses (“ltc1…” addresses), but not for P2SH-wrapped segwit addresses (see below).
- The existing field
isscriptwill now also report True for P2WSH addresses.
- A new field
embeddedis present for all script addresses where the script is known and matches something that can be interpreted as a known address. This is particularly true for P2SH-P2WPKH and P2SH-P2WSH addresses. The value for
embeddedincludes much of the information
validateaddresswould report if invoked directly on the embedded address.
- For multisig scripts a new
pubkeysfield was added that reports the full public keys involved in the script (if known). This is a replacement for the existing
addressesfield (which reports the same information but encoded as P2PKH addresses), represented in a more useful and less confusing way. The
addressesfield remains present for non-segwit addresses for backward compatibility.
- For all single-key addresses with known key (even when wrapped in P2SH or P2WSH), the
pubkeyfield will be present. In particular, this means that invoking
validateaddresson the output of
getnewaddresswill always report the
pubkey, even when the address type is P2SH-P2WPKH.
- The deprecated RPC
getinfowas removed. It is recommended that the more specific RPCs are used:
- The wallet RPC
getreceivedbyaddresswill return an error if called with an address not in the wallet.
- The wallet RPC
addwitnessaddresswas deprecated and will be removed in version 0.17, set the
getnewaddress, or option
dumpwalletnow includes hex-encoded scripts from the wallet in the dumpfile, and
importwalletnow imports these scripts, but corresponding addresses may not be added correctly or a manual rescan may be required to find relevant transactions.
- The RPC
getblockchaininfonow includes an
- A new
blockhashparameter has been added to the
getrawtransactionRPC which allows for a raw transaction to be fetched from a specific block if known, even without
fundrawtransactionRPCs now have optional
iswitnessparameters to override the heuristic witness checks if necessary.
walletpassphrasetimeout is now clamped to 2^30 seconds.
- Using addresses with the
createmultisigRPC is now deprecated, and will be removed in a later version. Public keys should be used instead.
- Blockchain rescans now no longer lock the wallet for the entire rescan process, so other RPCs can now be used at the same time (although results of balances / transactions may be incorrect or incomplete until the rescan is complete).
loggingRPC has now been made public rather than hidden.
initialblockdownloadboolean has been added to the
getblockchaininfoRPC to indicate whether the node is currently in IBD or not.
minrelaytxfeeis now included in the output of
-debuglogfile=<file>can be used to specify an alternative debug logging file.
- litecoin-cli now has an
-stdinrpcpassoption to allow the RPC password to be read from standard input.
-usehdoption has been removed.
- litecoin-cli now supports a new
-getinfoflag which returns an output like that of the now-removed
- The default regtest JSON-RPC port has been changed to 19443 to avoid conflict with testnet’s default of 19332.
- Segwit is now always active in regtest mode by default. Thus, if you upgrade a regtest node you will need to either -reindex or use the old rules by adding
vbparams=segwit:0:999999999999to your regtest litecoin.conf. Failure to do this will result in a CheckBlockIndex() assertion failure that will look like: Assertion `(pindexFirstNeverProcessed != nullptr) == (pindex->nChainTx == 0)’ failed.

Robinhood Testing New Cryptocurrency Wallet as Demand Rises
The millennial-focused trading portal is edging closer to launching a long-awaited app that will enable its growing user-base to send and receive cryptocurrencies.
A beta version of Robinhood’s iPhone app showed the company’s latest upgrades on the new digital asset features, according to Bloomberg.
There is a hidden image showing a waiting list for users eager to get their hands on the app and code referring to crypto transfers, it added.
Delving Deeper into Crypto
Robinhood users can already buy and sell cryptocurrencies on the platform but they need to convert them to and from USD. With a native app, users will be able to send crypto assets to each other directly and set up two-factor authentication for additional security.
Robinhood Chief Executive Officer Vlad Tenev stated that adding crypto wallets is a priority for the company’s developers and they are actively working on such.
“The ability to deposit and withdraw cryptocurrencies is tricky to do with scale, and we want to make sure it’s done correctly and properly.”
He did not specify a launch date, but the beta app leak suggests it is not too far away. Users of the new functions will need to activate crypto sending and receiving and the registration page will require an identity check, the report added.
On Sept. 11, CryptoPotato reported that Robinhood had launched incentives to promote longer-term cryptocurrency investing. The zero-fee recurring purchase feature enables users to schedule digital asset purchases for regular intervals with buys as low as a dollar.
This will encourage customers to build their cryptocurrency portfolios over time and “become a whole coiner,” stated Robinhood.
Robinhood Users Hungry For Crypto
Cryptocurrency trading has been one of the biggest drivers of revenue for Robinhood this year. Dogecoin has been the crown jewel, according to the company. It reported that 62% of its $233 million in second-quarter crypto income came from DOGE trading.
It added that more than half of all transaction-based revenue on the platform came from digital asset trading. The firm did warn that Q3 would not be as prosperous due to “seasonal headwinds and lower trading activity across the industry.”
Robinhood share prices have already fallen 43% since their all-time high of a little over $70 in early August. They are currently trading down 1.68% since Monday’s open at $40.70 according to Yahoo! Finance.

Snoop Dogg Reveals His Connection With Twitter Account on NFTs
Rate this post American rapper Snoop Dogg tweeted on Monday that he’s the owner of a Twitter account that talks about nonfungible tokens (NFTs). The account, named @CozomoMedici, shares “insights and tales from the wild world of NFTs” and has 27.7K followers at the moment. Snoop Dog Claims to Be Popular NFT Advocate on Twitter Snoop Dogg left the crypto community stunned this week after he revealed himself as the owner of a Twitter account dedicated to NFTs. The account Cozomo de’ Medici, named after an Italian banker, is only a month old. However, it has already garnered attention from industry watchers and even a mention from crypto-focused news outlet The Block. According to The Verge, the person behind the Medici account had been creating hype around their real identity for “at least a few days” and even conducted a poll for their followers to take a guess. The poll featured Democratic congresswoman Alexandria Ocasio-Cortez and Matt Bellamy, the lead singer of the rock band Muse. Snoop, however, was not mentioned in the poll. On September 20, @CozomoMedici tweeted that they were about to reveal their identity from their account. Shortly after, Snoop Dogg tweeted “I am @CozomoMedici.” Interestingly, after making this revelation, the Medici account bought two weed-themed collectibles from an artist named NyanDogg, The Verge reported. Additionally, Snoop’s alleged OpenSea account has been sent “a cloud of blunt and Snoop-themed NFTs” following the reveal. Is Medici Account an Elaborate Prank? The Medici account could likely turn out to be an elaborate prank, one that Snoop might have engineered himself or just participated in. Many reactions to Medici’s reveal have also expressed skepticism about Snoop’s involvement. “I have a hard time accepting that this account is Snoop Dogg. Like seriously Snoop Dogg muted his live stream for a week (?) by accident. And he is that deep into NFTs out here owning crypto punks… Owning Eth using OpenSea. Would love that to be true but I can’t believe it,” Twitter user @Brandolf485 wrote in the comments. Nonetheless, the crypto community will have to continue looking for concrete proof till Snoop’s involvement with the account is confirmed.

- Ethereum started a fresh decline below the $3,300 and $3,200 support levels.
- The price is now trading below $3,200 and the 100 hourly simple moving average.
- There is a key bearish trend line forming with resistance near $3,020 on the hourly chart of ETH/USD (data feed via Kraken).
- The pair could a steady recovery wave if there is a close above $3,050 in the near term.
Ethereum Price Corrects Losses
The bears gained strength below the $3,200 support zone. Finally, ether spiked below $3,000 and extended its decline. A low is formed near $2,807 and the price is now correcting losses. There was a break above the $2,920 and $2,950 resistance levels.
The price recovered above the 23.6% Fib retracement level of the recent decline from the $3,455 swing high to $2,807 low. An immediate resistance on the upside is near the $3,020 level. There is also a key bearish trend line forming with resistance near $3,020 on the hourly chart of ETH/USD.
