Bitcoin block explorer script prompt
An open-source Bitcoin solution written in Go language golang. It can be built for every platform that has a working Go compiler. It uses a proprietary license, though is free to use for non-commercial purposes.
Gocoin's architecture is quite different from the reference implementation of the Satoshi client. The core of the software is a library that essentially provides the blockchain protocol parser. That includes script parsing, ECDSA signature verification, but also things like address encoding, parsing of canonical signatures or extracting hashes that need to be signed for specific inputs of a given transaction. Inside the package, there is also a blocks persistent storage database blockdb. The core library interfaces directly with a UTXO database backed.
For this purpose Gocoin uses its own database engine, that has been designed to deal with the specific characteristics of bitcoin's UTXO database. To speed up the Elliptic Curve operations the secpk1 library by sipa has been ported to Go. The online client is a kind of a server software or a peer-to-peer node that is meant to be running all the time.
It handles the network related communication, feeds the core lib with new incoming blockchain data, monitors balances on the wallets' addresses, manages transaction memory pool and the peers database. It also provides an interactive user interface. The wallet application is responsible for creating private keys from a seed password and for signing transactions with them. It can also sign text messages with private keys and decode raw transactions.
Unlike the client, the wallet is not an app that is meant te be running continuously. A user runs it with the requested task - the wallet does the job and exits back to the command prompt. There is also a set of more and less useful tools github. For instance btcversig can verify a validity of a bitcoin signature - it is the substitute of the reference client's verifymessage RPC-API.
The tool type2determ can, at the other hand, calculate Type-2 deterministic addresses, without a need to access the wallet the private keys. It is possible to use Gocoin's wallet, without a need to have a running client node.
This may come handy since the node requires quite an advanced hardware and a large amount of time for the initial bootstrap. In such a case the required balance files are fetched with a tool called baliofrom popular block explorers.
The wallet app has very little hardware requirements. As long as you can build it for a specific architecture, it should work there. For security reasons it is strongly recommended to run the wallet on an encrypted file system, with an encrypted swap file. The software's first public release was announced in May on Bitcointalk forum. It happened twice that the client wasn't able to catch up with the blockchain, because of the implementation difference of the chain parsing protocol that was causing it to reject a block transaction that the reference implementation would accept.
In both cases the issue was fixed within single days. The fist case happened in July and the fix was introduced in version 0.
The second time was in March - the fix came with release 0. Retrieved from " https: Navigation menu Personal tools Create account Log in. Views Read View source View history.
