Stands for *Elliptic Curve Digital Signature Algorithm*. Used to verify transaction ownership when making a transfer of bitcoins. See *Signature*.
### Effective Amount
The total LBC amount assigned to a claim, including the original bid and any tips/supports. During a vanity URL takeover, the effective amount is shown as 0.
### Elliptic Curve Arithmetic
A set of mathematical operations defined on a group of points on a 2D elliptic curve. LBRY, similar to the Bitcoin protocol, uses predefined curve [secp256k1](https://en.bitcoin.it/wiki/Secp256k1). Here's the simplest possible explanation of the operations: you can add and subtract points and multiply them by an integer. Dividing by an integer is computationally infeasible (otherwise cryptographic signatures won't work). The private key is a 256-bit integer and the public key is a product of a predefined point G ("generator") by that integer: A = G * a. Associativity law allows implementing interesting cryptographic schemes like Diffie-Hellman key exchange (ECDH): two parties with private keys *a* and *b* may exchange their public keys *A* and *B* to compute a shared secret point `C: C = A * b = B * a` because `(G * a) * b == (G * b) * a`. Then this point C can be used as an AES encryption key to protect their communication channel.

The initial blob of a stream, which contains encryption information as well as points to other blobs required for a stream.
### Support (Claim Support)
A support is a wallet send transaction that includes claim information, which results in adding to a claim's effective amount. A tip is a special type of suppot that is sent from one wallet to another, so that the receiver can spend it to their own wallet.
### Takeover Period
In order to take over a claim at an existing vanity URL, the bid must be higher and takeover period must pass. In simple terms, the longer the claim is held, the longer the takeover period. For each month held, a day is added to the take over period for a maximum of 7 days. See [Claimtrie Bid States section here](https://lbry.io/faq/claimtrie-implementation) for more information.
