Welcome to IOTAmarkets! -- IOTA is a quantum-resistant distributed ledger protocol launched in 2015, focused on being useful for the emerging m2m economy of Internet-of-Things (IoT), data integrity, micro-/nano- payments, and anywhere else a scalable decentralized system is warranted. IOTA uniquely offers zero fees, no scaling limitations, and decentralized consensus where users are also validators. The digital currency 'iota' has a fixed money supply with zero inflationary cost.
Jeff Garzik talked about the "Fidelity Problem" since 2015. With the BCH stress test we are giving more confidence to institutions to build on Bitcoin. Time for miners to start making 32MB blocks and show the world what we can do!
 If you had free Electricity, what miner would you buy for mining bitcoin?
What is the most cost effective set-up where energy is free? There is a trade off between getting a high-hash-rate miner (that's also $$) and getting a low-hash-rate miner (that's less $$ but you would have to buy more power supplies)? Links would be helpful!
Miners: You'll (very likely) need to upgrade your Bitcoin Core node soon to support BIP66 | Peter Todd | Jun 12 2015
Peter Todd on Jun 12 2015: Summary The BIP66 soft-fork recently passed the 75% support threshold. This means that 75% of the hashing power has upgraded to support BIP66; 25% of the hashing power has not. Once 95% of the hashing power has upgraded, blocks created by the 5% who have not upgraded will be rejected. If you operate a pool, solo-mine, or mine on p2pool you'll very likely need to upgrade your Bitcoin Core node to support the BIP66 soft-fork, or your blocks will be rejected. If you only sell your hashing power to a centralized pool you do not need to do anything. How does the Bitcoin protocol measure BIP66 support? Miners that have upgraded to support BIP66 create blocks with the version field set to 3; non-upgraded miners set the version to 2. Bitcoin Core measures BIP66 support by counting how many blocks with version >= 3 exist in the blockchain within the last 1000 blocks. If 750 out of the last 1000 blocks support BIP66, blocks with the version set to >= 3 that do not follow the BIP66 rules are rejected; if 950 out of the last 1000 blocks support BIP66, blocks with version < 3 are rejected. When will the 95% threshold be reached? It's unknown exactly when the 95% threshold will be reached. The BIP34 soft-fork went from 75% to 95% support in a about two weeks, however more or less time is possible; it's possible that the 95% threshold will be reached in just a few days. How can I monitor BIP66 adoption? See Pieter Wuille's graphs:
http://bitcoin.sipa.be/ver-50k.png http://bitcoin.sipa.be/ver-10k.png http://bitcoin.sipa.be/ver-2k.png The 'ever' and '50k' graphs show the 75% and 95% thresholds. What software supports support BIP66? Bitcoin Core releases later than v0.10.0 support BIP66. In addition, v0.9.5 supports BIP66, however we recommend that you upgrade to v0.10.2 If you run a pool, you may also need to upgrade your pool software as well. For instance, eloipool versions prior to May 22nd 2015, git commit f5f4ea636fb38f38e6d9a04aad1f04427556a4bc, do not support BIP66. (For Eloipool, cb8a5e8fbb4bfdfe9e35f670082603caff65e1b2 is a clean merge that should work for any branch more recent than 2013 April 6) Solo miners and decentralised miners using GBT need to also update their mining software to a currently supported version of BFGMiner to get support for v3 blocks. The official BFGMiner binaries include this update with 5.1.0, 4.10.2, and 3.10.9. What is BIP66? BIP66 - "Strict DER signatures" - is a soft-fork that tightens the rules for signature verification, specifically the way that signatures are encoded. The Bitcoin Core implementation currently relies on OpenSSL for signature validation, which means it implicitly defines Bitcoin's block validity rules. Unfortunately, OpenSSL is not designed for consensus-critical behaviour (it does not guarantee bug-for-bug compatibility between versions), and thus changes to it can - and have - affected Bitcoin software. (see CVE-2014-8275) By tightening these rules BIP66 reduces the risk that changes to OpenSSL will cause forks in the Bitcoin blockchain, as seen previously by the March 2013 fork. Secondly reducing our dependency on OpenSSL is a step towards replacing OpenSSL with libsecp256k1, a signature validation library from Pieter Wuille and Gregory Maxwell, that is designed for consensus-critical applications, as well as being significantly faster than OpenSSL. Is it possible that the BIP66 soft-fork will not happen? In theory yes, though it is unlikely and rejection of BIP66 would be a very ugly process. Unfortunately the existing soft-fork mechanism provides no mechanism for a soft-fork to expire, so once set in motion there is no clean way to stop a soft-fork. There is a proposal from Wuille/Maxwell/Todd, to reform how soft-forks are adopted that aims to fix this issue, as well as allow multiple soft-forks be adopted in parallel: http://www.mail-archive.com/[email protected]/msg07863.html 'peter'[:-1]@petertodd.org 0000000000000000127ab1d576dc851f374424f1269c4700ccaba2c42d97e778 -------------- next part -------------- A non-text attachment was scrubbed...

Chihuahua Media Projects Ltd., 2A Simeon Pironkov Street Sofia Bulgaria, [email protected] The Bitmain Antminer S7 is one of the most popular bitcoin miners since it is easy to set up. In addition, the mining hardware is reasonably priced, powerful and efficient. Launched in 2015, the mining rig gained notoriety the following year with users claiming to experience an average of 4.7 to 4.9 TH/s hash rate. The problem is miners creating invalid blocks. Some software can detect that those blocks are invalid and reject them; other software can’t detect that blocks are invalid, so they show confirmations that aren’t real. Bitcoin Core 0.9.5 and later never had any problems because it could detect which blocks were invalid.
