In a blog post published shortly afterwards, the company said it will cease to support off-chain fund transfers between WazirX and Binance via the "Login with Binance" option on August 11. The feature currently offers a seamless way for Binance and WazirX customers to move their funds between the platforms in real time without having to pay any transaction fees. The idea catches on with city-dwellers who don't want the hassle and expense of owning a car, but want a quick and easy way to rent one by the hour. ● Tapscript resource limits: the bip-tapscript proposal limits transactions to one signature-checking operation (sigop) for every 12.5 vbytes the witness data adds to the size of the transaction (plus one free sigop per input). ● Why was 550 (MiB) chosen as a minimum storage size for prune mode? This week’s newsletter requests feedback on not allowing P2SH-wrapped addresses for taproot, describes proposed changes to script resource limits in tapscript, and mentions a discussion about watchtower storage costs. ● Watchtower storage costs: a discussion on the Lightning-Dev mailing list examined the storage requirements for current watchtowers as well as watchtowers for proposed eltoo-based payment channels. In the thread, Christian Decker notes that both current watchtowers (as implemented by LND) and future watchtowers for eltoo can have essentially O(1) costs (fixed costs) per user by having each person use a session key to update their latest state information on the watchtower.

However, many of these wallets also use P2SH-wrapped segwit addresses for receiving change sent from themselves to themselves. The Silkroad takedown in October may have not been powerful enough to pause the currency for the long-run, however, China's latest policies regarding Bitcoin surely aren't good for the once-regulation-free currency. Those of us in developed markets that haven’t experienced rapid inflation for decades may not see the need for it, but countless people in emerging markets have experienced many instances of severe inflation in their lifetimes, and tend to get the concept more quickly. If you are just starting and don’t have any previous experience trading, the first option gives a quick view of the market trading pairs and it is recommended before jumping to the more advanced one. This strips away one layer of cryptographic security, even for your BTC addresses. However, one service we surveyed supports spending money to native segwit (bech32) P2WPKH addresses but not bech32 P2WSH addresses. Past that, the field of cryptographic forms of money has extended significantly since bitcoin was propelled longer than 10 years back, and the following incredible computerized token might be discharged tomorrow, for all anybody in the crypto network knows.

Originally only of interest to the internet elite, Bitcoin has gained wider appeal in recent years and commands respect in its own right on the foreign exchange. The hardcoding, which is similar to the BIP90 hardcoding made a couple of years ago, simplifies Bitcoin Core’s consensus code. This week’s newsletter notes a change to Bitcoin Core’s consensus logic and announces a new feature on the Optech website for tracking technology adoption between different wallets and services. The News section from this week’s newsletter introduced a new feature on the Optech website. ● New Optech Compatibility Matrix: a new feature on the Optech website shows what wallets and services support certain recommended features, currently opt-in Replace-by-Fee (RBF) and segwit (with more comparisons planned for the future). ● Most tools support paying bech32 addresses: 74% of the wallets and linked web-site services surveyed support paying to segwit addresses. This ensures results for watch-only addresses are included in results.

1.2.3.4/32. If only an IP address is provided (i.e., no permissions are specified), the behavior is the same as before. 3391 always returns the same error message for failed payments in order to avoid leaking whether or not an invoice exists. The new field added in this merge returns the checksum for the descriptor exactly as it was provided by the user. The RPC already added a checksum to any descriptor provided without one, but it also normalized the descriptor by removing private keys and making other changes users might not want. For example, a motivation for the change was allowing bloom filters to be provided to particular peers (such as a user’s own lightweight wallet) even if the filters are disabled by default. 16248 extends the whitelisting configuration options in Bitcoin Core to allow specifying which services should be provided to different IP addresses or ranges. Although this isn’t the near-universal support we’d like to see, it may be enough support that we’ll soon see more wallets switching to bech32 receiving addresses by default. In some cases, this may have been done for privacy benefits (e.g. Bitcoin Core currently tries to match the type of change output to the type of payment output) but, in most cases, this seems like a missed opportunity for wallets to send change to their own bech32 addresses for increased fee savings.
